My Harborfreight X3 mill CNC conversion progress. Just done setting up the electronics. Took a quick video of initial test and configuration of EMC2 and Keling KL-6852 stepper motor drivers. Here is the X axis. Note on the scope, upper channel is the step pulse, bottom channel is direction which changes from 0v to approx 4V when the direction changes.
