Hi everyone.
Just found this group and I have been skimming through the posts.
I'm interested in building a CNC PCB mill/drill. Stepper motors,
linear bearings/rods, antibacklash nuts on Acme rod... and a Black
and Decker RTX. The resolution works out to 0.0005" per full step
and
0.00025" if I half step.
Is 1/2 or 1/4 of a thousands a good resolution for this project?
Does anyone have links to similar projects?
Hints? Tips? Insight?
There's a home-brew cnc yahoo group: cad_cam_edm_dro.
I found this group from a post in CCED. I hoped I'd get info here
since Bill (list mom) might consider this Off Topic in that group.
Thanks
mike
