Here are some pictures of my AT300 CNC conversion.
I Used 3x 282oz in steppers which seem powerfull enough however I think 2:1 ratio is the the best for all gears.
This mill has 2 weak points.
1. The brass Y-Axis nut on the treaded shaft is prone to wear.
2. Back lash on the Y-Axis shaft bearing.
Future plans will be to improve this some how.
The Modifications I made didn't damage/alter the Lathe so I can remove the motors later if I decide to sell it. |
