Hi, nice work! Does it fit the 25.4mm version?

Probably not without some modifications.

Hi WorkerDrone,

Neat design!

I have been working on building the first revision MPCNC design (vicious1's first revision of MPCNC 23.5mm (USA) EMT Conduit) but noticed that the center section is not as sturdy as I would like it to be. I am pretty sure your design will be effective in resolving that. Are the tool mounts compatible with the first revision MPCNC design also compatible on your WD_Platform_Mod Version 2? I am looking into using this tool mount: http://www.thingiverse.com/thing:1530328.

Thanks for your help,

FG.

MPCNC IE makita rt0701 tool holder

should be the same

I built a MPCNC - made it large, has a 4x3 foot (~ 1250x920mm) work space - and I've cut a few things, but, don't like the lack of rigidity. I am using the Dewalt DW660 and tried routing out in soft 2x4 pine, cutting across the grain with a 1/4" bit and the motor starts dancing around, even snapped the motor mount, had to print a new one. I was only cutting 2mm deep, and fairly slow. The problem is the lack of rigidity. Viscious1 just came out with a more rigid Z assembly MPCNC 525 . But, how much more rigid is your Z axis then the original MPCNC design? I noticed that you originally had 2 pipes on both X and Y and went to just 1 pipe on one axis, 2 on the other. Was that to regain more lost work area space, or did you find the added pipe didn't add rigidity? Also, i see you are using 3 pipes on the Z axis. I was even thinking of using 4 and using a timing belt to improve the speed, but, maybe the speed is fine. Is the 3 pipe design significantly more rigid then the 2? I will probably go with an 8mm lead screw - currently using the 5/16 threaded rod. If your design is much more sturdy then the original, i will give it a try. Probably too early to tell which is more sturdy - your set up or the MPCNC 525 ? What is your preliminary thought?

I believe my design does add stability, I'm happy with the mod.

I noticed that you originally had 2 pipes on both X and Y and went to just 1 pipe on one axis, 2 on the other.
The additional pipe proved to increase the resistance of movement more than providing rigidity so was discarded.

Also, i see you are using 3 pipes on the Z axis. I was even thinking of using 4
I can't see where 4 would give more than 3. Probably would just increase the resistance and cause problems.

What is your preliminary thought?

I haven't had a chance to use the 525 version yet. I actually intend to set up the new 525 z at some point and check it out; but, haven't had time as of late.

I would give the 525 mod a shot first, looks promising.

Do you have a pdf or doc file of the platform?

Someone maybe made IE version of this ?

Some serious heavy duty setup.
Very neat z axis rethink.

Nicely done,)

Thanks, really been working out great. I'm in the process of an 8 hour run on a fairly complicated 3d relief of an Eagle. I'll post a video in a few days showing off the MPCNC.

can you please upload skp file for 2014? please thanks great work

I added a 2014 save.

How much travel do you loose with this vs the stock arrangement?

I am getting 400mm x & y with 32" pipe. I can't remember exactly what I was getting before, I think around 450mm. Maybe someone else with a similar build can comment. I can squeeze out 425mm if I need to; but, so far haven't even come close to 400mm.

Great work !

Do you plan to release the IE version of this Mod ?

I have no way of testing an IE version. if someone will print out the parts and test for me I could try.

Just let me know if you find some time to create the IE version, I would be ready to give it a try.

sure, do you know how much to add in mm

Not quite sure what you mean. The tube diameter is 25mm. About the distances of the tubes to each other, Ryan aka Allted should be the best person to tell.

Yes looking at the tube diameter and distance between each on the z-axis. I'm starting a remix section and uploading a test piece.

Hi
I am at printing phase of build and wanted make your mod. I have IE version so i Have to remix your Project. I usualy work with solidworks so if You as author want to do it I ll by glad to help. Pipe of IE have 25 mm diameter but i seen that someone make project with 25.4mm diameter. I printed parts from IE version of oryginal mpcnc and they fit perfect. I can check stl diameter in about 5 hours. What you need Only diameter?

Yes I was just looking at the diameter difference between the IE version and the US version. I am starting a remix for the IE version and will upload a test part.

it is exacly 25 mm. it fits perfectly also rollers feels very stable. I start to print test pice. do you think about Moneyhead idea of put x & y pipe closer?

not sure or your question, any distance gained by tweaking the platform could easily be done by just making the xy pipes longer.

i print ie version and it looks good should work just fine

Would love to let my printer assist you! Just finishing the stock version...

This is awesome man, just what the machine needed. Very nicely done

thanks, Allted really made an awesome design, easily expandable

That's true, so many details that show his experience and genius. We can't thank him enough for his work.
