!!! READ THIS BEFORE PRINT !!!
After a lot of requests from the community, I share the 3D files for those who would like to start printing without delay.
This version of the TopsCNC Heavy in NEMA 23 version is still under development!
Most of the parts have already been printed but are NOT YET tested!
Some parts of the NEMA23 version are not yet Upload and may be modified.
For those who cant wait, I advise you to start by printing all the parts in common with the initial version in NEMA 17.
All the parts which have or could be modified are identified by a "_NEMA23" in the file name.
I would test and validate the pieces as I work on them (when I have time) and I will update this page with "update" points.
PS: If you want to say what you think of this version you can leave a comment at the bottom of the page, but if you want to communicate with our small growing community or myself, come on the Forum !
Before finishing I want to clarify that it is Stepper Online who sent me the NEMA23 motors, so I can test and validate this version, so a big thanks to them for allowing this version to exist!
Here is the upgrade video, but warning again, I will make another video for nema23 feedback on this TopsCNC Heavy :
Update 08/04/2020 :
At the moment, the motors which drives the Z axis will remain in Nema17, there is no point in switching it to Nema 23 and weighing down the machine for nothing. Especially since many NEMA23 (like mine) have a 10mm diameter shaft and I have not found a GT2 20 tooth pulley with a 10mm bore.
Update 11/04/2020 :
As some of people asked, here is "nema23 CNC Kit" link. I have the big version, with 3 individual drivers, I recommand them. They run so smooth !
Motors Links :
Big Nema23 CNC Kit : 3x BIG Nema23 + PSU + 3x Driver
Update 24/04/2020 :
Add end leadscrew holder and dragchains holder
Update 26/04/2020 :
I'm working on a improvement of the Z axis course and rigidity, please wait if you can !
Update 10/05/2020 :
I added folowing parts, this are final version to mount leadscrew from T8 to T14, only change needed is the "Nut holder". Theorically we should be able to mount SFU1204 ballscrews too !
For thoose who cant wait to start the build, you can start to print if the short Z axis is not a problem for you ! I continue to work on this point.
Update 11/05/2020 :
Here is finally the modification which allow us to gain 5cm depth on our Z axis ! I made initially a complicated thing, but finally I came back to a simple modification which involves these two parts:
- XAxis_FrontBottom.stl become XAxis_FrontBottom_moredepth.stl
- XAxis_FrontTop.stl become XAxis_FrontTop_moredepth.stl
- XAxis_FrontBottom.stl become also XAxis_FrontBottom_MoreDepth_Vacuum_Holder.stl (coming soon)
PLEASE NOTE: I have not yet tested these parts, if you start anyway it is your own responsibility :P
Update 25/06/2020 :
Sorry for the delay,here is the driver and PSU holder, I had completely forgotten...
Update 09/07/2020 :
I add the dust collector Holder for the "MoreDepth" Z version, Touched / Added files are :
