Greets everybody; I had gone back to an older $config because it had all the A axis stuff it it, and of course had to do a bit of fine tuning in the .ini file.
But when I fired off a proggy that used the M3-4-5 spindle controls, I wrecked the first piece of pcb material I put in the jig. Very carefully zeroed/homed to an electrical contact from the bit to the pcb, it ran a program that should have carved a recess in the board about .005" deep, but went a good 35 thou into it, At which point I noted that the spindle was running backwards. Humm, dig into the .hal file, and reading the newest integrator manual on about page 51, I started to search thru the file & find where I needed to add a reverse to the direction pin. I found a cw assignment, but not a ccw assignment, which, since that signal and the controller are rigged to reverse when that signal is true, and which it appears I could just change the name from -cw to -ccw to effect the logic reversal. But that killed all spindle controls because the value being delivered to pwmgen for speed was stuck at 0 according to hal-configuration->watch. But with that stuff scattered all up and down a 120+ line hal file, I got the brilliant (yeah, sure) idea to move all the spindle related stuff into one contiguous stanza in the file. Make it easier to track the setup, at least in my mind... Unforch, it is now complaining of a doubled pin assignment but the complaint is hidden behind the splash image. I think, I only see it for maybe 50ms before the monitor goes blank and I have to hit the hardware reset to get it to reboot. ATM, I cannot find a doubled assignment in the file. I just checked the times on the emc_debug.txt and emc_print.txt files, and it is not updating those for my startup attempts so I don't have any clues from there. grepping the hal file for parport.0.pin-14: net spindle-ccw => parport.0.pin-14-out grepping for pwmgen: loadrt pwmgen output_type=0 addf pwmgen.update servo-thread addf pwmgen.make-pulses base-thread net spindle-cmd-with-only-positive-magnitude <= abs.0.out => pwmgen.0.value net spindle-enable <= motion.spindle-on => pwmgen.0.enable net spindle-pwm <= pwmgen.0.pwm setp pwmgen.0.pwm-freq 100.0 setp pwmgen.0.scale 1583.33333333 setp pwmgen.0.offset 0.108421052632 setp pwmgen.0.dither-pwm true grepping for spindle:# put all the spindle stuffs here net spindle-cmd <= motion.spindle-speed-out net spindle-cmd => abs.0.in net spindle-cmd-with-only-positive-magnitude <= abs.0.out => pwmgen.0.value net spindle-enable <= motion.spindle-on => pwmgen.0.enable net spindle-pwm <= pwmgen.0.pwm net spindle-ccw <= motion.spindle-reverse net spindle-ccw => parport.0.pin-14-out net spindle-pwm => parport.0.pin-16-out And because the motor controller has no clue, the reversing is being done with a reversing relay controlled by parport.0.pin-14-out, there is an abs function for the pwm speed, grepping for that: loadrt abs count=1 net spindle-cmd => abs.0.in net spindle-cmd-with-only-positive-magnitude <= abs.0.out => pwmgen.0.value addf abs.0 servo-thread How do I best proceed to locate this critter is the question? I want to know what I did wrong & put some notes in the binder. Thanks guys & sending wishes for Happy & Prosperous New Year to all.
