Summary: M4 + CSS = incorrect spindle command outputs
Initial Comment:
CSS mode with spindle going backward gives incorrect output on
motion.spindle-forward, motion.spindle-reverse pins.
To reproduce:
G96 S200 D2000 M4
Expected result:
spindle-speed-out negative and proportional to radius
motion.spindle-reverse TRUE
motion.spindle-forward FALSE
Actual result:
spindle-speed-out is correct
motion.spindle-reverse FALSE
motion.spindle-forward TRUE
halcmd: show pin motion.spindle
Component Pins:
Owner Type Dir Value Name
5 bit IN FALSE motion.spindle-at-speed <== SAtSpeed
5 bit OUT FALSE motion.spindle-brake
5 bit OUT TRUE motion.spindle-forward ==> SpindleFwd
5 bit I/O FALSE motion.spindle-index-enable <=>
SpindleIndexEnable
5 bit OUT TRUE motion.spindle-on ==> SpindleOn
5 bit OUT FALSE motion.spindle-reverse ==> SpindleRev
5 float IN 1777.53 motion.spindle-revs <== SpindleRevs
5 float IN 6.62607 motion.spindle-speed-in <== SpindleSpeedRps
5 float OUT -368.1428 motion.spindle-speed-out ==> SpindleSpeedOut
