Hi Sam - no am not using that. Here's the relevant bits out the hal file. The lines with # at the end were added in an attempt to smooth it out. (I'm a bit laid up at the moment, has some vision problems in my right eye over the weekend - went to hospital and was operated on yesterday for torn and detached retina - cant see much at the moment and machines are off the menu for the next 10 days or so :) addf lowpass.0 servo-thread # net spindle-cmd <= motion.spindle-speed-out => abs.1.in net spindle-abs-cmd <= abs.1.out => pwmgen.0.value net spindle-enable <= motion.spindle-on => pwmgen.0.enable parport.0.pin-14-out net spindle-pwm <= pwmgen.0.pwm setp pwmgen.0.pwm-freq 0.0 setp pwmgen.0.scale 18000 setp pwmgen.0.offset 0 setp pwmgen.0.dither-pwm true net spindle-cw <= motion.spindle-forward net spindle-ccw <= motion.spindle-reverse setp encoder.0.position-scale 480.000000 net spindle-position encoder.0.position => motion.spindle-revs net spindle-velocity encoder.0.velocity => motion.spindle-speed-in net spindle-index-enable encoder.0.index-enable <=> motion.spindle-index-enable net spindle-phase-a encoder.0.phase-A net spindle-phase-b encoder.0.phase-B net spindle-index encoder.0.phase-Z setp lowpass.0.gain 0.01 # net spindle-velocity encoder.0.velocity => lowpass.0.in # net spindle-rpm-filtered <= lowpass.0.out # Steve Blackmore -- ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
