I am just wondering if this printer is still being in use for everyone in this group? After getting better printers, I will say, mine has been moved to the corner of the bench, still used but rarely.
Sadly, no longer. The thermometer got intermittent and print quality had degraded over time recently anyway. It was an extreme-buget printer and has lasted me 6 years. Pretty good going for an introduction to the field I'd say.
I now have a Prusa i3 MK3S+ and it's a m a z i n g in comparison... A different world. Yes, I invested - in easier more reliable printing :)
I'm still using mine. I recently got a heated bed for it but unfortunately, the connector on it won't fir the plug on the mainboard. I am also planning to buy a new mainboard after I heard the issues of heated beds burning out the original mainboard, and because I wanted a mainboard with silent motor drivers.
My heat bed on mine is not powered by the mainboard, it has it's own temperature controller that I use either an old power supply to power it or I could plug it into the wall(outlet)
I have been considering purchasing or using a separate power supply for the bed, but I'm actually looking at getting a new mainboard, the SKR Mini e3. It has silent motor drivers which is the main reason I want to use it, and it would of course have provisions for a heated bed and doesn't have the issue of burning out that connection. So rather than spending time and money on a temporary solution I'm just waiting to get a new mainboard.
That, of course, will come with its own set of problems. I'd have to make firmware changes but I should be able to get it to work.
I actually already have a BigTechTree version of the the SKR e3 already sat on a shelf which will eventually be replacing the Polturs now aging Ramps controller, though everytime I go to have a look at doing it I find the Ramps is still doing its job flawlessly and just cant bring myself to tear it all out (the whole "if it aint broke" mentality)
Yes, when I get the urge to run it (although it has been several months) I have how ever, just lashed out and bought another machine with a larger swept area.
Add me to the list!
I recently found a 'PrintRite DIY' and a 'PrintRite Compact' both second hand but hardly used and incredibly good value for money.
On the DIY I moded the 'front to back' rails which may have been unnecessary in hindsight but taught me a lot.
I also added an air duct that stole half the air from the extruder fan and redirected it to the end of the nozzle. This was a great success so I did a remake detailing the changes.
It would be better to have a dedicated duct and fan, which can apparently be connected straight into the board as can the heated bed. I think the stories of people frying the main-board may be putting me off as both these jobs have been on my to do list for a while now, couple of months at least.
Also, I've been reading this forum and someone suggested that the up and down stepper motors aren't very good either, they go out of sync. I'd seen the negative affects of this but just had to re calibrate ALOT, I hadn't put it down to the motors not syncing. I'd bolted the thing down to the work top and got to the point where I just gave one of the threaded bars a twist every so often and knew it was pretty close. I'm assuming its a pretty simple swap for a same spec but better quality motor.
If anyone has any advice or tales of what not to do as regards fitting a 'piece cooling fan' and a 'heated bed' and upgrading the stepper motors then please let me know, all advice would be gratefully received.
Another thing I'd like to do is re-configure the frame so that the left to right rods are above one another (like Prusa) instead of side by side which I'm sure negatively affects print quality. However...... is it worth it, should we just spend the money and BUY a solution rather than fixing what we've got? Until I can justify spending for a new one, I'll be fixing what I've got.
Whichever way you look at it, I think the DIY is fantastic and has hopefully inspired many people to take a spanner or a screwdriver to it.
Gonna go and big up the Compact on it's forum now!
update : there isn't a Compact Group 8(
diy - prusa conversaion ihttps://www.thingiverse.com/thing:1792378
designed and made that a while back, kept it in that config for a fair amount of time too, did the job well
the other choice is to just go all in for the increased options, greater flexibility and skip the Mk1 Poltur and go straight for my current evolution of the printrite DIY, the Poltur XL V2.0
made it 3 years ago and absolutely nothings broke, nothings failed, everythings still ticking along niceley on the salvaged DIY hardware
Hi shawdreamer, I only discovered your reply today and I just spent 3 hours down a rabbit hole of your creation haha.
Your designs are great, the first PolTur design is inspiring and although I'm not going to build the whole thing in exactly the same way, I will be using some of your ideas on my PR DIY remake.
Thanks for sharing your ideas with everyone and thank you for bringing it to my attention, can't believe I hadn't seen it before tbh, nice one!
Gonna go and have a look at your XL version now.
Hmm, might have to look at your v2 in a bit. I have been debating trying to cad up a holder for a pen to mount to mine.
As the UK has been in lockdown off-and-on for much of the last year, I'm glad to say the PrintRite is still running well and has got over its "noisy period" - with a bit of lithium grease - and is back to 100% smooth operation. As it is one of the very few creative outlets here, I'm so glad it is still up and running all this time.
Good to see you up and about,
Did you print anything special to keep z axis leveled and stop wobbling? Mine will walk itself out of level eventually.
I find it used to "go out" when I struggled to insert PLA through the feeder. I've taken to rounding the end with a lighted match first. This prevents such struggles.
Don't be too long with the match - or the PLA starts to burn. Not good dripping burning plastic on your printer :-o or anything else for that matter.
So, with careful filament changing and rounded ends, I find it does not go off kilter so often. Remember - when the motors are switched off they have very little resistance to being turned, so almost anything can knock them out of synchronisation. Maybe load filament whilst the printer is starting a fake print, to provide more resistance? You get about 2 minutes which should be plenty. Push some filament through once it gets hot - to prime it (or add some start-up commands to do this, or both.) Then turn off and on again to give it a clean start, and away you go.
Mine has been in use for 5 years - not in a mass production facility but it has made 100s of items - around the house, RC aeroplanes, and for others, etc. Very good printer once you add a glass bed and use double-sided rubber tape for the bed. 3D print yourself some shorter stand-offs to keep vertical capacity.
Yes. Had to rebuild and change bed as bearing holders broke and let the X bearings free. Luckily I had another machine to cannibalise after buying a demonstrator cheap last year.
I thought I would comment - my collido has just been brought back into service - the thermostat went so I changed the print head and thermostat - it is now printing the headbands for masks as part of 3Dcrowd.uk - running constantly during the day and evening - very reliable little printer.
Hi there, Mine's sort of still in operation although the printer itself still has most of its original components it now has Ramps 1.4, an e3d v6 extruder, a proximity switched z home instead of a microswitch, heated bed of course and wiring from a mad scientist's laboratory. As a retired engineer I checked out alignment in all sorts of directions and gradually homed in on as near a perfect set up as I was happy with. One of the first things to go was the plastic bed which was replaced with 10mm aviation quality aluminium plate and a Geckotek magnetic build plate. I keep messing about with the idea of auto levelling but I can't properly get my head round it, anybody with a solution would be welcome lol.
I keep thinking about retiring the machine and getting a new one but I still think there's plenty left that's useful.
Sorry to be late. Lockdown issues.
Auto-leveling is not necessary. 3D-print yourself some shorter stand-offs for the base. Buy some 5mm silicone sheet and put a sheet of glass bed on top of it on the plastic one. Make some screw-down ally clips for the corners. Shim the glass up with carefully cut "contour shapes" of paper until it's level and true. Job's a good 'un. Level forever. This is what I've used the past 3 years. No adjustment required.
where the original printrite was concerned I actually found that all the loss of levelling over time could usually always be traced back to the twin Z axis motors running out of sync rather than anything else mechanical on the machine, even to the point that the bed hadnt moved even a fraction of degree but you'd strangely lose level anyway.
auto bed leveling works by adjusting one of either of the two z axis motors individually until it achieves and balanced level across the bed, the thing is the very same result can be achieved by manually manipulating the z axis rod by hand, takes less time, costs nothing and without the added hardware/software it also means yet one less thing to go wrong on a printer that can often be temperamental even in the best circumstances.
coincidentally, even after I salvaged the parts from the printrite to create my Poltur printer design I found the two z-axis motor would still fall out of sync over time which just confirmed my suspicion that colido had likely just used the most super cheap Nema's they could get hold of.
I still would love to convert mine over to your design. While I was moving it a month or so ago, I accidentally ripped the wiring harness out of a connector to the stepper motor(Z ironically) I havent really cared enough about it to buy the new harness from HobbyKing and pay more in shipping than the harness costs
the connectors for nema motors are pretty much generic tbh (there are a rare few specialized types for more high end printers etc but the colido DIY is far from that catagory lol) so you can pick up a far cheaper set of new cables or even a whole harness off somewhere like ebay/amazon for a fraction of the price Colido have placed on their own, I snapped a couple of connections on the extruder plug during the creation of the Poltur (twas sausage finger syndrome) and as I had the exact same spare connectors available (some flight controller use them, notably the original Ardupilot) I replaced the entire plug....fiddly....sore finger inducing.... and time consumingly annoying.
wasnt till after I found the whole generic harness for under a tenner on ebay (facepalm)
I cant seem to have that luck finding one I guess, I found one for a luzbot and it was $60
here's a simple single lead with appropriate plugs, just look for similar in "Y" configuration if you need the splitter version for the z motorshttps://www.ebay.co.uk/itm/Nema17-4-wire-Stepper-Motor-Cable-4-Pin-XH-2-54-6-Pin-JST2-0-Connector/114154187094?hash=item1a941ea956:g:YKkAAOSwZWlgJU7r
OH those. I thought it was going to be the whole harness lol.
Yes, mines is still in use, not as often as I used to use it, but that's due to my bad health, nothing to do with the printer itself.
It does require a fair bit of setting up but the results are still very good, the axis guide rods are starting to show wear marks but the thing still keeps on printing.
Considering the original cost and the few parts I have made for it, this printer has been well worth the money spent.
I've patiently been waiting on it dyeing to do a Ramps replacement on it, as I really liked the idea of having more control, however as they say... if it ain't broke don't fix it, so I'm still waiting :o)
It's still a load of fun, and been going now for over 4 years. almost 5.
I bought a Compact at Xmas (my first 3d printer), had a great time and then ordered a Anycubic Mega-S direct from them for a steal in their new year sales, I use this mostly, but recently bought this Colido DIY for silly money (£60) with the intention to use it to learn much more, experiment and upgrade. Just bought an Ultrabase heated bed 220x240, bigger than needed but the DIY has lots of room, so now I have to construct a Y carriage plate for it, fit some springs and add a bigger psu & relay/mosfet. It is noisy though, any tips?
Install it on a 600mm x 600mm (2' x 2') kitchen worktop segment. Buy 3 soft squash balls and use the holders in my objects. Quietens mine down nicely.
I dont think there is much that can be done to quiet it down, replace the fan with one that is quiet but then the whole machine is loud, bearings There is a member in this group that made his own printer based on some of the DIY parts, it's called Poltur. you can find it in the things section of the group
skip the Poltur and go straight to converting it to a XL v.2..... the original is three years old now, used everyday, never really failed me and and still going strong.
Oh wow impressive
Welp my Printrite is officially done for unless I can find a wiring harness for it, cheap
original printrite harness is currently 14 quid from HK, considering the usual pricing they place on printrite spares that actually quite cheap lol
Yea it's like $16. I was surprised as well. Now lets hope it's still in stock by the time I get enough to make it worth shipping it lol.
I was moving the printer lastnight, planning on doing a long print with it as my other printer is to loud(fans sound like bushings) anyway, and 2 of the wires that goes into the plugs for the stepper motors ripped apart on it. Or the cat chewed on it while it was at my folks house
Iirc the PR uses uses the standard micro-jst plugs both ends so its likely you can just pick up a single replacement cable off eBay if you dont fancy buying the lot or having to wait, failing that you can just buy some plugs and un-crimped ends to repair the damaged one... Bit fiddly with a pair of needle nose pliers but could save you a couple of bucks.
I cant seem to get it to connect to a slicer now anyways. using the 115200 baud rate, and the com port that it shows.
You can just save to SD and plug it in. Runs without consuming computer resources - and electrical resources!
I've been upgrading in the past year with various things found on Thingiverse, some stuff I made myself, and a little bit of hardware (fans, heated bed, ...). It seems to print quite well with some upgrades.
Mine now has a heated bed powered through the regular board but with a better PSU, a fan to cool the tip, better Z axis, upgraded bearings, and a better filament spool holder. Looking forward to experiment with a different print head and better stepper drivers on a different ramps.
The PrintRite DIY is much fun to improve. Some of the hardware is quite okay, and some things are easy to improve so I guess I'll keep it around for a bit longer.
Status update: Upgraded to RAMPS a while back. Recently added a bowden v6 with BMG extruder using shawdreamer's STLs (thanks!). Just now upgraded further to a Klipper setup.
Had some issues with shawdreamer's extruder assembly but it works! I had to use the Dremel on my print to make everything fit nicely and might use the analysis to design a more optimal fan duct. An airflow analysis of the fan duct shows there's substantial room for improvement. I might post a remix on some parts if time permits.
I'm still tuning in the klipper setup but it seems to work fine in general. The motors run more quietly and it's possible to bump the speed further.
The Bed Mosfet for my rostock decided to smoke itself, so as my PR still doesn't have a heated bed, it now has a not cack control board. For the first time I can do prints without the extruder skipping steps at the drop of a hat.
I still use mine, it is definitely the biggest of the build areas I have. Until recently was still even using the original board, with just basic mods like y/z axis brackets, bearings oh and replacing the warped ass guide rods on the x axis. Then last couple of weeks it has been given an...alternate board. Has a bit more punch in the drivers than original PR board, so no more click of sadness from my extruder. so it is again my designated big stuff printer
Mine's still bveing used (and abused) PR motherboard got binned and converted to RAMPS after the usual heated bed etc. Printed a case for the RAMPS stuff but not got around to actually using it MOSFET bed tamp control after a bit of a smoking incident. Oodles of power available from my 30 amp power supply, wires everywhere might frighten some I just call it "interesting"
Still using it with nice results :-)
just got a ender 3pro, today. thinking of converting this to a DIY laser cnc or something laser....why not!!!
Both this one and my Anet one are both benched at the moment. I haven't had the time to sit down and repair them.
The Printrite needs a new heater as the wire snapped during an "upgrade"
The Anets temp sensor fell out and cooked the entire print end, now jams up printing longer than 10 minutes regardless of what I try.
Absolutely, It just works. My X5S is constantly in need of adjustment and or repair. I'm using the DIY for detailed prints now by installing a .2 mm nozzle and making appropriate setting changes. The print quality is very good.
twas the secret to PR's DIY limited success..... simplify and cheap'en (shame they concentrated on the "cheap'en" part more though), once you start to get more complicated rigs like Tronxy's X5 range there's more to go wrong.
with a coreXY or Delta when you start getting any kind issues you can quickly realise the cause maybe several factors..... with a Cartesian..... the belt needs adjusting LOL
Yes, it is still my only one printer. It works pretty well (with some minor maintenance here and then) but it is robust, prints very well and most importantly, it is still the smallest one!
Mine is just used for flexible filaments now after MANY upgrades/alterations. It still works fine, but I prefer my Creality CR-10 for the PLA/ABS jobs, and I have an Anycubic Photon that is great for smaller detailed work.
Mine died a little while ago. Instead of spending money on it, I'm planning to get a more sturdy-framed printer as a replacement (thinking of a cr-10) Maybe i'll tinker around a bit with the leftovers though. Only the hotend seems broken, so maybe I'll try to equip it with a laser or something like that.
Just bought a cr10s-pro but still using my printrite as a second printer.
Mine is still going strong. Did plenty of upgrades over the years. I'm going to build a D-bot and all parts are printed with the PrintRite.
Bought another printer - but this one is still faster and more reliable than any of the others I have access to
mine still lives on in its PolTur config though bit by bit the hardwares starting to die off and be replaced, original PR endstops were the last recent ones to be swapped out, surprisingly though the motors are all still rock solid performers.
Mine is packed up since I moved onto a Monoprice Select Mini Pro. I got tired of the catastrophic fails, the gouged print bed, the poor print quality, etc. It might run okay if given some TLC, but in my current situation I'd much rather have the printer that prints smaller but more reliable and detailed prints.
It was a decent educational experience and starter printer for me, though. Made me learn more about the settings, issues, dangers, etc.
