Hi, I hooked up one of my g201's and I am having a problem. When the
jog buttons are pushed, the motors make a buzzing sound but do not
move. I am switching from thstep25 drivers and I am using the same
breakout board and mach-3 settings as before, but the steps/inch have
been changed to match the 1/10 microstepping. I have tried reversing
the motor winding wires as mentioned in the manual and the motors
still sound the same. I have tried my 80v power supply and my 35v
power supply with the same result. I have tried different motors. I
have tested the common 5v, which I tapped from my breakout board, and
it measures 4.73v. I am using 2.8A nema-23 motors and I have a 33K
ohm resistor across the current set terminals. the red power light
always comes on. I am out of ideas, and this is the only machine I
have and I use it for production, so ideas you have will be greatly
appreciated. thanks
