Making progress. Dedicated Ethernet at the moment. So far I've been able to see the charge-pump signal (stepper #04) show up on DB25-17. Machine Enabled on DB-25-1. And all DB-25 pins for the 4 motors show step pulses when they are jogged. Limit switches appear to work.
Haven't been able to get the PWM for the spindle working but that doesn’t really matter at the moment because the Spindle AC Servo I bought takes step/dir but not PWM. Instead I decided to add another step generator. Using pncconf it shows up as StepGen #5 on pins 2,3 of the second parallel port named P1. The problem is that the HAL file contains an axis.9 and as a result now LinuxCNC won't run. ./Stretch-MESA.hal:306: Pin 'axis.9.motor-pos-cmd' does not exist Included with this posting is that error and the fragment of the HAL file that defines all the spindle stuff. Everything for the stepgen.05 is fine until: # ---closedloop stepper signals--- net s-pos-cmd <= axis.9.motor-pos-cmd net s-vel-cmd <= axis.9.joint-vel-cmd net s-output => hm2_7i92.0.stepgen.05.velocity-cmd net s-pos-fb <= hm2_7i92.0.stepgen.05.position-fb net s-pos-fb => axis.9.motor-pos-fb net s-enable <= axis.9.amp-enable-out net s-enable => hm2_7i92.0.stepgen.05.enable As the hal and ini files were generated by pncconf what could cause this? The axis steppers in the ini file are all defined as [AXIS_n] and the spindle as [SPINDLE_9] so I can see how an axis.9 might show up but no other definition anywhere else. Must be really simple but not obvious. Any ideas? Thanks John
