Grizzly G1006 Milling Machine CNC Conversion - LinuxCNC

23/10/2012  Add Chinese ball screws, at least for X and Y, to eliminate the backlash. I'll get a max speed upgrade too, by eliminating the friction of the Acme screws. Put CUI encoders on the ball screws. Then I can have a true CNC system with relatively low cost stepper motors but also have servo feedback of the motion to generate following error and close the loop on the stepper motors. That would allow

Grizzly G1006 Milling Machine CNC Conversion -

23/10/2012  Part of the reason that I didn't do the CNC mill conversion earlier is because it seemed like such an exercise in turd polishing.

That little milling machine has paid for itself five times over on the simple and occasional jobs I've done. It's probably paid for itself ten times over if I ...

Ballscrew Upgrade - How To Make Your Own CNC Milling

01/11/2014  I decided to upgrade the Acme Thread Leadscrews to BallScrews. A Ballscrew (sometimes spelled Ball Screw) is a type of linear actuator that translates rotary motion into linear motion. It uses ball bearing in a helical groove to transfer the motion with very little friction. Because of this low friction fit, ballscrews have less backlash or slop than Acme leadscrews and allow you greater ...
