I am trying to dial in my steps on my X, Y and Z for my 4x4 Altmill. What ± tolerances could I expect the Altmill to hold?
@tresguey I think I remember seeing the stepper motor resolution in the documentation along with the corresponding xyz directional movement. If you search, you’ll probably find it. I’m not at my computer and don’t have the patience to look from my phone
Pretty sure it was better than 0.01mm. I have a 0.01mm resolution digital dial gauge and did measure XY movements in that increment. I didn’t check z.
This article does have information on steps. But there’s no corresponding information on the xyz movements that I could see.
I got mine and doing test cuts I was getting within 0.05mm diametrically from programmed size using cheap end mills.
Edit: Worth mentioning I’m using a Makita while I wait for the ATC. Run out isn’t great.
