When is PID too high??
« on: January 04, 2010, 03:42:21 PM »
dspMC / Mach3 conversion on a V2XT. Using Axis Works software. Tuning the axis motors (servo) and the machine wouldnt do the same thing twice. Started out at "P" 4000 and "D" an times 25 factor which is 100000. Motors run very smooth but going back to zero is all over the place. All ways and screws are in very good condition. Lube pump is working. I have the P now at 25000 and the D times 25. Seems alot more accurate within 2 or 3 counts. Scale has always been 100. What do I do, just keep going? Or am I way out of typical range as it is. Stock SEM motors and 250 encoders. Anything less than 2500 P wont move the motors. Your thoughts??

Also, motors have a tach but I have the amps in torque mode right now. Still learning
