Re: New STEPPERONLINE Integrated Servo motor

Re: New STEPPERONLINE Integrated Servo motor

Thank you, Keith. Currently I have 8mm screws, which gives me 3.175" pre rev and 1600 steps per rev on my cheap open loop motors. And no measurable lash. I do not think I can easily upgrade my screws to high quality ballscrews due to gantry setup, but when I get my new motors, I definitely go ...

I got the exact same treatment from Centroid with my KP-4 probe. The customer service regarding the probe was terrible. I sucked it ...
