If I can see a signal on halscope what in my hal file would prevent it from occurring on the physical I/O? My axis work perfectly. The only difference I can see is in hardware. My i/o pin through the hal file is linked to the servo thread not the base thread. Also based on the halscope scaling I believe my pulses are within the 100 to 10kHz range. I have tried multiple thread rates to manipulate that value with no luck. Coincidentally I don't see a upper limit on PMDX-131 in the manual. They do however specify the 100 Hz low end. I have used the published values from the CNC4PC board and tried values from 100Hz (low end of PMDX) to 15500Hz high end of CNC4PC. My next test will be to see if that output pin works at all.....static on/off. I know Pin 1 works to control my spindle through the on board relay. Have not used the others...until now.
