Magnifico trabajo el suyo.Por donde empiezo a imprimir?

Hello, pour l'axe X j'ai pu remarquer qu'il valait mieux prendre une tige filetée de même longueur que le profilé alu, comme ça on peut mettre également un roulement au niveau du bâti pour le rendre plus stable.

Super projet en tout cas

building this machine could have been so much fun, but it's turning out to be a frustrating experience. the lack of documentation is the primary cause. the lack of design files the secondary. Things are too small with too less tolerance. this inevitably leads to cracks, as can be seen on your own parts in the video.

you really should mention that we need 4x T8 lead screws + nut and not just 3 times. please correct it. now waiting another 1-2 weeks for missing parts to arrive ...

I mention the 4 lead screw, read the whole list one more time ;) I write 3x T8 100mm shorter than aluminium profil, and 1x 200mm T8. When you think about the machine 10seconds, that become logic that you need 4 lead screw.
However, as I did in the video, I spent some time to clean all parts, to got correct tolerance, 3D printed parts cant be perfect. But things are not to small, all my pieces got correct size. Maybe your printer is not correctly set up ?
I have 1 cracks on 1 only pieces, because of too thin wall, and it's corrected in the v2 which come out soon.

looks incredible... I am brand new to 3D printing but I am going to give this a shot. Did you use limit switches on the end points?

Thank you,
No limit switch, I use software limits

Vivement la v.2, mon panier d'achat de pièces est prêt et l'imprimante 3d aussi! Je trépigne d’impatience.... :)
Vraiment du chouette boulot! Continu! Et merci pour le partage.

Bonjour,
Super de partager toutes les infos :)
Je souhaiterais un peu modifier le projet pour y adapter une torche plasma à la place de la défonceuse (quelques idées ou plans)?

Je souhaiterais une table ou je pourrais mettre la partie de découpe ferait 1100x1100mm.
Les moteurs néma17, support en alu 40, courroie... qui sont avec la description plus bas seront-il suffisant?
Sachant aussi qu'au niveau T° et projection le plasma c'est autres choses que la défonceuse -> fabrication de pare chaleur lol

Merci D'avance pour les infos :) et encore excellent travail :)

I would also like to use a plasma torch for the TopsCNC! I would like to offer my help in any way possible! I am almost done with basic unit. Will post a make very soon

I would be concerned with the heat of the plasma torch weakening the Z carriage. PLA weakens rapidly at even fairly low temperatures

Where would the heat generation be most prominent (i.e the mount for the torch, or possibly all pieces directly above the cutting area)? My current build uses PETG which is generally more robust than PLA but I would consider breaking out the CarbonF Polycarbonate for a plasma build. From what I understand it has a much lower heat transition and with the aid of a coolant jet/water table, I wonder if it can take the heat. That said, operating the torch by hand doesn't generate any extreme heat (at least not degrees 200c), however, the time between cuts are also increased. Please lmk your thoughts NCDoug! Thanks y'all have a good one!

My concern was the parts above the torch. I would assume the handle was sufficiently well insulated. Yes, a water tray is going to absorb a lot of the heat, but not the radiant heat from the plasma. Covering the carriage with something reflective, such as aluminum foil, would help.

Thank you for the swift reply NCDoug! I will remember to consider the use of a radiant barrier. I will also do some testing/research when I start that build and see what materials are stable enough for high temps. I may fabricate the Z-carriage to run on square steel tubing with 608 bearings and remix the X-axis holder to match. I'm not even sure that this router table can move at the speeds necessary to get clean cuts with less dross so this is more of a working theory lol Thanks again!!

I don't know what your application is, but have you thought of water jet cutting? There are a number of tutorials on line on how to make a water jet nozzle from a pressure washer.Water jet would be pretty slow, so the speed of the system wouldn't be an issue.

With a plasma system, you aren't going to need a motorized z-axis, so you could use a much simpler set-up for the Z cart like the sort that are used for laser cutters. That would be lighter, and thus react faster than one designed for a milling/routing head.

Hello sir, any idea on when v2 will be released? I'm currently ready to make one, but unsure if I should wait a bit more.
Great project!

Thank you very much for designing and sharing this nice CNC. I cannot await until v2.0 gets released, so i can start printing things and ordering pieces needed for it.

Any idea when the HD version will be available? I just received my order of 5kg of PETG and tuned my slicer settings, so I am ready to get printing, haha. I almost started printing this version again, but I know we are so close to you releasing the new HD setup.

Hello,

pourrais-tu apporter quelques précisions sur la partie éléctronique stp? Par exemple pourquoi partir sur du microstepping? Y'a t-il besoin de configurer les A4988?

J'en suis à l'étape où j'ai pu tout connecter ensemble, j'arrive à connecter mon PC à l'installation via UniversalGcodeSender et à envoyer 2-3 commandes, mais les moteurs tournent à peine et je ne sais pas trop quoi faire ensuite...

Merci d'avance

bonsoir

Je n'arrive pas a trouver le roulement qui bloque la Vis mère 200 mm T8 comme on vois sur la video (à 5:04)
pouvez vous me donner la référence ou faut prendre ceci https://fr.aliexpress.com/item/32909412373.html?

merci

Oui c'est exactement ceux la, je les ai récupéré très facilement en faisant levier avec un tourne vis ils sortes tout seul

Hello! Thank you for sharing a great project. I think I will start redoing my old CNC. Great project. Thanks!

Thank you !
Have fun it's cool to build a new CNC

Bonjour et merci pour le projet.
Une fois la Heavy en ligne, celle ci sera toujours disponible?
JE compte en faire une de surface raisonnable donc celle ci me suffira je pense.
Combien faut-il compter de différence entre la longueur des profil et la surface de travail? par ex si je prends des profil de 50cm, quelle sera la taille de la zone de travail?

Merci d'avance pour la réponse

Oui évidemment celle ci sera toujours disponible ! En effet pour sur surface raisonnable elle est suffisante, j'en suis pleinement satisfait.

Il faut compté environ 15 a 20cm de moins que la taille des profilés. Pour exemple, avec mes profilés initiaux de 60cm, j'avais une zone de travail de 45 x 45cm :)

Super merci!

what software do you use for osx control software?

I use CNCJS ! :)

I can see why you made this as the prices are super low. Here in the USA the same items from Amazon is 3 to 4 times the price (6 USD becomes 24).

Its actually cheaper to build in the USA using aliexpress and ebay for most of the parts. Here is my BOM for this great build. The whole build was under $ 165 + 3 kg of filament. I used Overture PLA Black at $ 12 a roll as part of a 6 pack and a intro discount. You could save even more if you used the correct sized smooth rods and bushings.

I recently purchased some Overture PETG clear and fell in love with them over Hatchbox but in the following two weeks of purchasing it went up from $11.99 to $16.99 which makes it not nearly as good as it was.

Thank you for the bom and for the price you mentioned wow.

Yes. I have had really good prints with overture filament. I did notice the price has jumped in the last few weeks though. Probably due to the global shortage in PLA right now. Hopefully in a few weeks it will go back down. You can still get a good deal if you get the 3 pack of black or white. Use "10offnew" at checkout and each spool is $11.30 . Right now their PETG is a good price for a couple of colors. Think I'll give that a try next.

Bonjour,

Votre travail est très intéressant ! Cependant je me perd un peu dans la description, celle que vous présentez ici : https://www.youtube.com/watch?v=uwwWx9bmHhY est elle la version Heavy ?

Si c'est le cas, seule la longueur des vis sans fin et des profilés aluminium change ? non ?

Merci pour vos lumières !

Merci !
Non ce n'est pas la version Heavy, c'est la version simple avec de plus grand profilé, je travail actuellement sur la Heavy :)

Ok, j'avais commencé sous fusion à me faire un système semblable à base de profilé 3060 parce que j'avais peur sur une distance d'un mètre que ça ne plie ...
Vous êtes plutot sur la fin ou sur le commencement de la version heavy ??
Merci d'avance.

Je la sort la semaine prochaine je pense

Oh man, I am so excited. Sounds like I will be doing a lot of printing around Christmas! Keep up the good work.

Merci pour le partage !

I just started printing all of the files. I have only two brackets printed at this point and noticed that v2.0 will be coming out soon. I guess I will just stop printing now and wait until the new version comes out. Do you have a timeframe for when you may release the newest version? By the way, I absolutely love the engineering and craftsmanship that went into all of those. Job well done. I am very excited to start building my own CNC. Are you thinking of upgrading the electronics in the new one as well to handle bigger motors and a bigger spindle?

Hi !
For Now I will keep my actual motor / spindle / electronics, then for the material the V2 will need more aluminium profil and V-Wheel and the new 3D printed file set :)

Now you tell me! I have almost finished designing my own stronger version (see enclosed picture) with thicker aluminum hardware and more wheels, and I see your post. Ah well!

Fantastic. I was about to purchase the electronics anyways, but wasn't sure if you were going to upgrade from the 17 motors to the 23. When do you think you will have the v2.0 fileset available for us to start printing?

Also, are you going to be creating a new "Thing" here for the v2.0 with all the files in one place, or are they going to be mixed in with the older ones as well? I almost started printing some 1.0 parts and saw that there were 1.1 and newer parts that replaced those. Real close to printing parts I didn't need, haha. My recommendation would be a new thing to keep them separate personally. Thanks again.

I will create a new thing I think yes

Hello,

bravo pour c projet, je trouve ça génial.

Petite question, pourrais-tu donner un peu de détails sur la partie électronique (ce qu'il faut en dehors de l'arduino/CNC shield), comment tu as réalisé les branchements, l'alimentation et le branchement de la spindle... Et pourquoi pas un peu sur la partie grbl ^^

en tout cas superbe réalisation, la mienne est en train d'être finalisée (partie mécanique on va dire ^^)

Bravo pour cette belle construction.

Je vais construire ta machine, qui pour moi est l'une des meilleurs du genre.

Pour la liste des pièces à imprimer, c'est 1 fois chaque STL ?

Le reste est parfaitement clair.
La liste des pièces est ridiculement basse sur aliexpress une fois les équivalent trouvé, Bravo..

Du Canada ;)

Bonjour,
ça m'a l'air bien sympa tout ça...

Si je résume ce que j'ai compris pour le moment :

On a besoin de (je suis en France pour l'estimation des prix...) :

  • 2/3 kg de PLA (voir un peu d'ABS pour la partie attache de l'affleureuse) pour ~200h d'impression
  • ~200$ de matériel divers (converti en ~200€ au cours du $ informatique...)
  • ~200€ d'affleureuse makita (ou un Chinese spindle ER11, j'en ai vu vers 70€ mais je n'ai pas cherché plus que ça)
    = Entre 300 et 400€ de fourniture

On choisit la taille des rails et donc l'encombrement global (et des travaux possibles), et si ensuite on veut agrandir (ou rétrécir mais j'y crois moins), il suffit de racheter des rails, de réimprimer des morceaux de chaîne et tout démonter/remonter.

Les trucs en plus :

  • un PC de contrôle
  • une table / support etc.. pour accueillir la machine et maintenir le support à graver / découper
  • un aspirateur de chantier
  • un boîtier / caisse / truc pour contenir toute l'électronique un peu à l'abri
  • une ou des fraises si ce n'est pas fourni avec l'affleureuse

N’hésitez pas à me corriger si j'ai écrit des bêtises...
Je sens que le père Noël va avoir une longue liste de courses cette année...

Exact, tu peux prendre une Katsu a 50euros aussi ( https://amzn.to/2EqTVr1 ) mais je sais pas ce que ça donne niveau faux rond pour ce prix la ...

Sachant que je travail sur attention spoiler en avant première une version "Heavy" de cette CNC, avec des pièces imprimé beaucoup plus solide, un Axe X beaucoup plus solide et rigide, des axes Y doublés et renforcé etc...

Coté matériel général, mis a par des rails et quelques roulettes en plus, ça ne changera pas grand chose mais par contre elle sera beaucoup plus gourmande en plastique (disont 4 ou 5kg)

Je vais attendre un peu pour voir alors :)
De toutes façons j'ai des travaux en cours pour préparer mon atelier avant de lancer une nouvelle machine...

This doesn't look lined up. Seems like it would use a bit of correction.
Great looking project though :) Following

Comments deleted.

I had the same issue but has been fixed by adding a washer for each bolt.

I would suggest putting eccentric nuts on the wheel axes - increase the hole diameter to fit 7.2mm, and then you have the possibility to adjust the gap to fit exactly.

I really like the crank on the z axis. Great idea. I will have to add that to mine. Also like the stiffener bars on top. I was going to stiffen the z flex with a block between the z axis carriage but will give your method a shot first.

Yes and i will design a piece to print to prevent this flex

This is a really nice one ! Good job !!

Hello topsie,
could you tell me when you will give some instructions about electric assembly? Is it possible to use tutorials about ESTLCam or CNC-board assembled at MPCNC?

Kind regards!

bonjour, déjà merci pour ce projet au top! je viens de mettre en route ma cnc mais mon transfo ne me délivre pas assez de puissance (vielle alim pc(très vielle même)) du coup qu'utilises tu pour puissance stp? merci

Désolé pour le temps de réponse
j'utilise ce genre d'alimentation : https://amzn.to/2PFpdQ4

pas de soucis, merci pour ta réponse!

Bonsoir, est ce qu’il y a un possibilité d’optenir les plans 3d modifiable, je veut bien intégrer des profile 8040 et des nema plus grandes, si c’est possible, je te transmis aussi mes changement à vous

Tu peut modifier les fichier .stl suivant le logiciel que tu utilise, moi je les modifie avec sketchup et sa fonctionne très bien.

Pas en solidedge, il ne permets pas de convertir du stl dans Une model 3d

Hello ..

Wonderful work .. have you tried it on Aluminum ?

Thanks

Yes, it work !

Superbe machine

Je voudrais savoir si des Nema 17hs 4401S suffisent
car j'ai vu ce kit sur aliexpress
https://fr.aliexpress.com/item/4000154720711.html?spm=a2g0o.cart.0.0.5e5e3c00a6nl5k&mp=1

merci

Oui ça me semble suffisant vu que la transmission est par tige fileté !

In different videos regarding the MPCNC users explained that stepper motors with only 40 newtonmeters could be to weak for CNCs. They recommend the usage of stepper motors with at least 59 NM. Maybe this machine could have the same problems.

Regards

Yes but MPCNC is belt trasmission, here I use leadscrew to move axis, so less torque is necessary ^^

Hi Topsie,
very happy to hear that, because I've ordered motors with only 40NM. Initially I wanted to build the MPCNC but after watching your videos I decided to build your construction.
Two questions:
What size of the bed would be easy to handle?
Is it possible to use ESTLCam with your CNC too?

Kind regards,
Günter

Super design!!
I’m starting in it however having some questions
Are the 2040 profiles strong or;rigid;enough for the xl;machine, or should I integrate 4080 »or 6030 profiles?
On the arduino cnc shield, is there enough IO to integrate endstops and tool leveling, I Will need 7 inputs at least

Yes it's strong enough to cut wood and plastic, but keep in mind, the more big machine is, less rigid it is.
To cut big aluminium pieces, it's may be a good idea to use 4060 C Beam or something else for the X axis, and 2080 for y axis.
Yes it seam to have enought input for endstop and tool leveling !

Hello ! Super projet ! ca me donne très envie de franchir le pas :)
J'ai vu qu'il fallait 2kilo de PLA, en terme de prix global pour la version 1.2m ca revient à combien au total ?
Si jamais tu es pas loin de Grenoble tu peux venir au Laboratoire Ouvert Grenoblois (Hackerspace) on sera ravi de discuter de ta CNC , on a un projet similaire .
Merci !

Hello merci !
ça reviens aux alentours des 400euros en tout :)
ça aurait etait avec plaisir de passer malheureusement je suis sur Marseille ...

Bravo vous êtes un génie

Mdr merci xD

Hi,

Thank you for sharing this project. It's a great job!
Can you publish the Arduino code used, please?

Thank you,
Virgil

Arduino Code is "GRBL", which I got it from here : https://github.com/gnea/grbl

It's really simple to install and use, the whole code is documented and have a large, LARGE community ^^

So about to start printing all parts. While watching your new video it shows removing the back feet. So we no longer need to print rear support?

In the new V1.4 i use front feet as back feet to screw on the "end T8 support", so you have to print 2 time the front feet (left and right 2 times) if you want to use "end T8 support"

Awesome system! What's the stall torque on the Nema 17's you used? Obviously bigger would be better, but yours seems to run pretty smooth and strong!

Thanks !
I use 4 commonly used Nema 17 "1.7A 84oz.in (59Ncm)" to drive this machine :)

Thanx a ton. Never knew you get them in so many torque configs until I started pricing this project up :D Very excited to start printing

Всем привет, вопрос если поставить двигатели nema 23 на ардуино, какие лучше использовать драйвера к ним? Заранее спасибо

Sorry but I dont know :X

In this project, what are the aluminum profile measurements?

they are 20mm x 40mm x what ever length you want. The lead screws should be about 100mm shorter then the profile length If I recall correctly

Right, I cant give a better answer !! :)

hey! THIS IS A GREAT JOB! CONGRATS! There is any way you can modify the Z axis to 200mm Ø12mm chrome steel rod and LM12UU linear bearing and NEMA 23 stepper for more power and speed? If not, can you share/sale the editable project? Thank you!

Hey ! Thank you :)
Yes I will put all editable file for FREE on my website which is in developpment ! :)

Greeting,

I can only say wowuu on a remarkable project. I'm very thrilled with the details of how you designed it. I got a stteper motor a long time ago and I would ask you to put parts in the project for Nema23 motor

Hi ! thank you :))
I hope to find time to make nema23 part in next week

Hello!
I LOVE your CNC project, in fact i was looking for building one and ended up with your youtube video. However I have no idea on how electronics works with the CNC, nor the software I need, nor the things I have to buy.
I see you have a buy-list, but it's not that easy to buy since half of the list i don't even know what are those for, but will get much better if everything is ilustrated. If you have time to list everything with pictures or just sharing the links from where you bought all of them would be much better!

Best regards

Here is my ali and amazon list. Prices are to the USA and in US Dollars. I started building the MPCNC which is why I have 12mm rods and bushings. If you use those, I have remixed the z carriage for that size.

Hey, thanks a lot! This makes things much easier!

Hi, thank you !
Yes, I work on material list based on amazon / aliexpress link, and on a video to explain electronic :)

TOPSIE te felicito por el aporte, dan ganas de ponerse armar una, se ve que usaste arduino para la electrónica, puedes enviarme información de la parte la electronica. Saludos ROAN

Hi, thanks !
Yes I will make a video about electronic :)

Hello, Super projets. Juste quelques petites questions :

  • Je vois dans tes visuels que tu l'as dessiné en 3D, pourquoi ne pas le sortir en complet en .STEP (la manipulation du step est vachement plus agréable pour la prise de cotes, etc)
  • tu n'utilises pas de "butée"/bouton de fin de course? Ou ai-je louper qqch.
  • je remarque que tu utilises une double vis sans fin pour l'axe Y. Comment es-tu sûr du fait qu'ils tourne exactement de la même manière, a la même vitesse?
  • aussi dans ta version agrandie, tu as des vis sans fin très longue (toujours l'axe Y). elle n'a pas tendance a plier quand tu travaille en extrémités?

Sinon, super travail.

Hello, merci !

  • Oui j'y pense a sortir les .step
  • Non j'utilise un zero et des fins de course logiciel
  • Pour la double vis sans fin en Y, aucun soucis car les moteurs pas a pas sont fait pour ça, ils ont un nombre de pas defini par tour, niveau vitesse on les pilotes pas après pas a intervalle défini, pas de soucis de désynchronisation :)
  • Non je n'ai pas eu de problème pour le moment avec de longue vis sans fin, même en bout de course ^^ peut être qu'un diamètre T8 poserai un problème de flexibilité au delas de 1.20m en effet

encore merci, et merci aussi pour les questions pertinentes !

Encore un tout grand merci pour se design très bien pensé, j'ai fait ta pub un peu partout

Merci ! Elle est super en noir :p

Hi, i cant find bearing used in z axis bottom to fix lead screw. Can someone provide link or smth?

Hy, buy an t8 lead screw Support:
https://images.app.goo.gl/E5wS9vSexX1Fec4P9

remove the bearing from the holder and you have what you looking for ;)

How about this idea. Level indicator dial meter. And square dial meter addons? :)

Your machine is install for my gun work :)

But I need some addons for square the pistol slide to be perfect matching CNC axis:)

Hello,

thank you for the upload of your wonderfull design.
Can you also please make a video abaout the Software you are ussing for the Arduino and also for the CNC task himself and how it works?

Thank you

great design but when can we have the v1.4 files thank you.

Good afternoon, tell me about your machine, do you use it only for cutting sheet material? We didn’t have a chance to make bariliefs on it, curly wood cutting .. Thank you

Hello, thanks for this nice design :)
I would start print all parts, is it possible to get the Files for v1.4 ?
Thanks a lot!

King Regards
Emils

Hello and thank you very much to bring this great CNC up and sharing your work with us.
I have started printing parts and need v1.4 Files to complete this awesome machine. Please upload your v1.4 Files ASAP.

Kind Regards,

Thank you !
I will upload it in few hours !

Thanks for fast reply, also I need to know the bearing number that used in Front Top Z Axi and End Lead Screw Support please?

Hi, love the look of this build! I’m just starting to gather and print parts to make this. It will be my first attempt at CNC.

Just a quick few questions, What did you use as a power supply? I was thinking of using the same as what is on my ended 3 pro its 24v at 14.6 A , do you know if that’s suitable? Also have you thought about adding a small screen or anything(if possible) ?

Cheers

Hi ! Thank you :)

I use a standard DC 12V 20A power supply, like used in LEDs light or something else :) I think 24V is to much for the CNC shield, but I never really try it sorry :/

I will maybe do some upgrade for the electronics but a screen is not planned because you need a Computer next to your CNC to drive it !

I will add some features like end-stop or a DIY "RPM Meter" :)

Hi, adding another vslot in the x axis to the rear of the frame would make it more sturdy right?

Hi, not really in my opinion :/

Thanks for sharing your work here - this is a really great design! You actually might want to complement your dust collector assembly with an inexpensive Cyclone to save some money on those expensive filters and bags :-)

30L workshop dust cyclone (stage 1) for less than 25€

Thanks but I have a really good Karcher Vacuum wich do a really good job without any bags !

Nice design. Please tell me how much time did you print the parts and how much did you use the filament for this. I am asking because I'm trying to do your project.

I dont know how much printing time I spent because when developping a machine I print some part, wich not fit perfectly so reprint it with some little modification etc...

I think I use someting about 3Kg of PLA to make it complete.

Nice design! Thank you for sharing it. In order to understand it better I have imported the design into Fusion 360. Would you allow me to post the Fusion files so others can benefit?

Sure you can ! Good job I love it !

Thank you!

Great job. Thanks for doing that.

Hello! Thanks for the project! What you think of I’ll use 2x2020 aluminum profiles instead of 1x2040? Will it work? What about using PETG instead PLA?

Hi !
For 2020 profiles I think that will lost some rigidity, but why not !
For PETG I dont know, all parts are not constrained with a lot of pressure or torsion, it maybe increase really a bit the rigidity but not so much

salut,
il serait possible d'avoir les fichiers mais pour du 3060, je maîtrise pas trop les log pour modifier tous sa.
merci à toi....

Je vais me renseigner sur les 3060 et voir si je peux adapter les modèles 3D :)

Si tu veux je t'en envoi un bout. ;)

Will the aluminium clamp mount that comes with the most ER11 Spindle Motor on aliexpress bolt directly to the Z axis cart without modification?

Comments deleted.

Nop sorry :/
I made a holder for Common ER11 Spindle that I use in test actually, when i validate this holder i will post parts in v1.3, probably tomorrow !

Cool, Thanks for sharing this awesome project, it is appreciated. I finished printing most of the parts except the updated chain and almost everything ordered from aliexpress is here. I was about to order a makita spindle when I saw your update.

Thank you !

The parts are tested and all work well, I uplade v1.3 part today

Super boulot.
La même avec du profil 60x30, des excentriques pour le réglage est nickel.

Merci :)

Oui je suis d'accord pour les profils 3060, les 2040 manque de plus en plus de rigidité sur de plus grandes longueur.

Par contre pour le serrage des roues sur profilés, j'ai volontairement évité les excentriques ! J'ai mis en place ce système de serrage à vis car j'ai une mauvaise expérience des excentriques sur CNC, qui ont la fâcheuse tendance a se dérégler avec les vibrations lors du fraisage...

What is the pitch for the T8 screw? I've got several to choose from on Amazon, including 2mm, 4mm, 8mm, 10mm, and 12mm. I imagine that would affect the rate and precision of the movements. Or, is that something you just adjust for in the settings of the program?

Each revolution, your T8 nut will travel 2mm or 4mm or 8mm etc... :)

Right, but maybe you could just answer the question. If it doesn't matter which one I choose because the software compensates for my choice, tell me. Try being helpful.

For the same motor speed : The less mm the nut travel each revolution, the less you have travel speed BUT the more you have torque.

Logic, Right ?

Now I hope you know this, but here is a reminder :
Each stepper motor, like NEMA17 used here, use a serie of step to rotate. For NEMA17, it make 200 FULL steps by revolution. 400 HALF steps by revolution etc... wich is configured by jumpers put on CNC Shield, under each motor driver.

Okay, So now, in GRBL you have some parameters ($100 $101 $102 -> X Y Z) wich define the number of steps by milimeters.
With a really simple calcul, you can find your parameter value.

But to be helpful, let's do a exemple for you !
With X axis ($100), 8mm pitch and NEMA17 with jumper set for HALF step (400steps) :
$100 = "Nut travel each revolution" / "Number of steps of your motor" = 8mm / 400steps = 0.02mm/step

Simple, Right ?

So 0.02mm is you machine precision. To increase precision, you have to increase step division (remember, the jumper on CNC Shield)

Is it helping enough for you ? If not, tons of tutorials are available on google.

It's basic knowledge if you want to build a CNC.

I'm sorry. You have obviously been helpful since you made the design I am printing in the first place. Thank you for providing more information, that was above and beyond what I was asking about.

Just please keep in mind that what you think is basic knowledge for you, the expert, may not be for a layperson.

No problem !

So let me know when you start to build it !

Comments deleted.

You're right. I was being snarky. I'm not an expert at CNC and it felt like he was talking down to me.

trying to source the parts. Do you have a link for the t8 end bearing. Thanks

For now, I actually dont use T8 end bearing :)

What is the bearing in your video that fits in the front upper z part that stops the t8 rod from dropping?

Ooooh okay sorry my bad !
I use bearing that I'v got from this kind of part :
( it seems sealed but you can get it by turning it with a screwdriver or something else)

Thanks. That was what I had thought about using. Great feedback!

I immediately liked this super project. I've already printed almost all the parts, except the spindle support I don't want to buy other milling machines, I'm waiting for the Chinese spindle er11 upgrade, I hope you can post it soon. again congratulations,

Hi you do CNC but you can not make your parts. A kick then fusion 360 and the turn is played you have the support adapted to your milling machine

Ahah, No problem I will make the part if needed ^^ it's more simple for me to do it and it will add one more possibility to use the design ^^

Thank you !
Yes maybe tomorrow for the standard ER11 spindle !

The machine looks awesome, ordered all my parts from AliExpress at a total cost of about 200$ - looking forward to them arriving:)

I do have to make some changes for the printed parts as my printer only has a 10x10 bed size, but I'm hoping I will achieve the necessary stability.

Also, I would love to see a video or two of the machine in use:)

Thank you !
200$ it's a really good deal !
But yes, with a 10 x 10cm printer it's a bit complicated :x
Maybe can you invest 150$ in a Ender 3 printer ? Ahah
Good luck with the project, let me know !

I did buy some extra parts with that will allow for a bed width extension, so if necessary I hope that'll help:) Apart from that my hobby budget is kinda blown, so I'm hoping the wife will buy me an Ender 3 for christmas... :P

Ahah hope for you ;)

This just keeps getting better. Great Job on the updates. Half way through printing the parts for this and you drop your updates. Back to the printer for me as the drag chains are amazing. I can't wait to see what you have up your sleeve next.

Thank you !!

is there any update on 500W ER11 Spindle holder ? :) or can we use the old one from the first cnc machine ?

oh by the way. what GRBL software do you use ? :D

The old one from the first CNC machine have not the same screw system, but I will very soon design a 500W Spindle holder, stay tuned ;)

Now I mainly use "CNC JS" which is based on Node.js technology, but I previously use "grblControl" wich work very well !

Wonderful, great job! I already have one printed machine. And your machine is my upgrade.
The video is also wonderful and clear.
Keep updating.
Thanks !!!!

Thank you !
I am currently making improvements, upgrades, and the video that goes with

Hi
I did some changes:

  • first one move the motors back
  • design les square
  • design part for the end of the lead screw so it won't be in the "air"
  • Use aluminum profile 30X30 mm (SIMA)
    Thanks
    Dubi

could you share the stl for the designed "part for the end of the lead screw so it won't be in the "air""?

Its a good idea for long range machine, for a 60 x 60 cm machine it's not really important, but for machine in 100 x 100cm it can be usefull, i will maybe design a part for it ! Thanks for idea

Was just starting to purchase parts for the Dremel CNC when I came upon your great design. Looks far more rigid and easily scalable. At least I can use most of the parts to build this design. Have to find something else to do with the 12mm rods and bearings. Maybe I'll try and remix the Z carriage. Nice video as well. Very helpful in understanding how it is put together. Great job.

Thank you !! :o

Merci pour votre beau projet!

Wow! I love this. I'm a large format vinyl & print person and I've always wanted to get into CNC. This seems the perfect place to start! ... Just started printing the first few pieces last night : )

Followed your parts list and sourced everything thru Amazon here (USA) the cost of the parts, including the router, everything comes out to be around $435.00 ... (minus the nuts & bolts which I can buy locally)

That's not bad at all! : )

But a question I have is since it says this is a work in progress, have you come across anything you wish have done differently now that yours has been up & running for awhile? ...and... Have you run into and issues of the heat generated by the Makita and being printed in PLA filament... Was thinking of maybe printing those 2 parts in ABS...

Cheers for the time & effort you spent into making this excellent project!

I myself would like to see the lit of parts as I am having trouble finding the right leadscrew.

Curious if you have an Amazon list of parts you used? That would be really helpful.

Thank you !
All parts here is part I printed to make my CNC
I have actually no problem with makita and PLA spindle support, but it can be a good idea to print spindle support with ABS :)

Great design.! Is there any good links for the wheels ?

Thank you :)
I just write "creality wheel" on amazon and i got it ahah

Amazing build, Looks good, and much better look than my Dremel CNC.

Thank you !!

How rigid is the Y-Gantry ? do you think you can do fine work like PCB track routing ? Milling aluminum ?

For a 3D printed PLA machine, she is reaaally rigid, more than I hoped !
In my opinion, milling PCB track routing will be really easy, and for aluminium, I did some try quickly, and with fine speed and depth adjustement, it should be a usable !

Great idea for tension on the delrin wheels, I feel like those are the weak link in my system. Really keen to see how this turns out in the long run. Myself I am just busy with a new Pick and Place machine but I am using 12mm rod and belt drive. Its my first Fusion360 project all my others are OpenScad / Librecad. My current PnP is lasercut 6mm stainless 2040 and delrin wheels with lead screws.

Niiiice !
I will maybe use your dragchain design to manage my cable :))

Do you think it would be possible to do a remix that uses makerslide and V-Wheels ?

What an amazing job! Good work !
