General Mach Discussion / spindle speed encoder conection
« on: December 14, 2007, 10:28:35 PM »
I have been having a time trying to get my spindle up to speed with the cncpc c6 board. I can get the spindle to start but can't get it up to speed.
tried the spindle tuning and it takes off full throttle and won't turn off. I click the spindle off and it goes full out and when I click it again it slows down(the on state)click the down rate and shuts off. so I thought if I put an encoder on the motor I could have control. Question is how do I tell mach3 where to look , I connected encoder outputs A to pin12 and B to pin 11.
