I have made just the nema 34 mount

I apologize for that being incorrect, I still have not corrected it. Would you mind sharing the corrected file? I can upload it as to not cause anyone else any issues. Have you used any of the other components? I'd be interested to hear how it went. Hope to hear back. Would love pictures! Videos!

the bolt holes on the nema 34 mount are the size for bolts that fit a nema 23motor. the 34 mount needs to have the holes enlarged to the same diameter as the the holes on the nema 34 motor.

The consolidated NEMA 34 mount motor mount bolt holes are a bit smaller than the actual NEMA 34 motor mounting holes. Can you tell me what size bolt they were design for?

I'll have to get back to you on that, I'm trying to find the drawings I based everything off of, but I'm away from home currently. I never got to test the Nema 34 mount as I used Nema 23. Do you mean the thru hole diameter of the bolt holes or the nema 34 spacing? It's possible I got something wrong, uploaded the wrong final version, or the drawing was wrong. I remember there being a lot of conflicting information in the different designs vs the machine dimensions etc and revising things many times. Again I sourced information from a lot of different peoples conversions. I apologize if it does not work for you, but please report back what you find out and I can try to fix it and or remove the part. I didn't use the consolidated version either, I used aluminum spacers on the 3d printed bracket. Does the bracket fit your machine dimensions otherwise? I've also had issues with some programs either over or under sizing, skewing things.

Very cool!

I'm in the same position as you - will be 3D printing initial motor mounts and using the stock leadscrews for a rubbish CNC setup, then using that to make steel mounts and buying ballscrews.

Did you get yours working?
