Could anyone help? My DIY 3 stepper / axis router, Y axis is not turning. Gantry moves freely by hand pulling the belt drive. I've double checked my wiring, tried another stepper motor driver and tried another stepper motor. When the controller is turned on the Y axis stepper motor holds it position but if I try to jog, the stepper motor tries to turn and makes a high pitched sound. Other 2 axis work fine. I'm thinking it could be a setting in Mach3 or the CS labs IP/M plugin (I may have messed about with some settings and forgotten how it was set up when it was working).
I'm using CS Labs IP/M controller, DMA860H drivers and low inductance Nema 34 for Y axis. Soft limits and proximity switches for homing.
It was working fine then it became obvious it was losing steps on the Y axis running a job. Then Y axis packed in.
Any help would be greatly appreciated!
Thanks...Chris
