General Mach Discussion / MaxNC spindle setup
« on: March 30, 2007, 11:02:52 PM »
 I'm setting up my Maxnc 15cl with Mach3 and have got the axes moving properly, but am having problems getting the spindle to work. I've tried using the PWM setting, but the motor pulses badly unless I set the base freq. at about 50, but then the rpm's are way out to lunch. Everything I've read in this forum and the manual says that I should be using step & dir., but I can't get that to work either. As soon as I power up the machine the spindle motor starts up. I've tried changing the active low setting for the spindle which is set to pin 1, but still the spindle starts when I put power to the machine.

What am I missing?
