Motors Stop In Middle Of Commands

Post by xnex » Sat Mar 18, 2017 6:34 pm

Ive had this little CNC and I cant get it to work properly. I think it might be my wiring but ive never heard stepper motors do this so im lost. Could it be wiring or GRBL? All help would be much appreciated. I have a video of it happening here (Audio might be helpful): https://www.youtube.com/watch?v=mthU4WsmcV8 and here, https://www.youtube.com/watch?v=k3ni4vKbRNQ

You are trying to move the steppers too fast.

To quickly resolve the problem, reduce your Steps/MM ($100/$101/$102). Try 30. Then calibrate your axes for the correct value to put in $100/$101/$102.
