General Mach Discussion / Re: frustrated....cannot seem to get a motor stepping
« on: March 24, 2011, 05:09:41 PM »
I figured it out! I built the HobbyCNC board over a year ago but ended up putting the project off until now. During the construction of it I remember checking voltages and what not but once it was completely assembled I must have stopped following the instructions....basically I had no motors to test at the time so once soldering all components was completed I stopped. Today after cracking the case that holds it open and going through the instructions I found that I never moved the jumpers used for the VREF to one of the applicable micro stepping settings. Once the jumpers were moved the motors hum like crazy and I could'nt turn them by hand! Opened mach3, motors moved correctly, mission complete! Thanks for the excellent and quick answers ger21!!
