They have similar names despite the fact that they are different things. You could probably argue that DEFAULT_VELOCITY belonged in the [DISPLAY] section. And maybe DEFAULT_ACCELERATION should be TELEOP_ACCELERATION [Edit] I just noticed that the PID MAXERROR is set to 0.0005. Set this to zero, I seem to recall this is a Pncconf bug. If that doesn't help, then.... I don't actually know what is wrong. Your config looks a lot like the sample configs (such as parport/gantry) The first thing I would do is short-circuit the feedback loops just to be sure that it isn't something very odd. For the X1 and X2 axes change: net emcmot.00.pos-cmd axis.0.motor-pos-cmd => pid.0.command net emcmot.00.vel-cmd axis.0.joint-vel-cmd => pid.0.command-deriv net motor.00.pos-fb <= hm2_[HOSTMOT2](BOARD).0.stepgen.00.position-fb axis.0.motor-pos-fb pid.0.feedback to net emcmot.00.pos-cmd axis.0.motor-pos-cmd => pid.0.command axis.0.motor-pos-fb net emcmot.00.vel-cmd axis.0.joint-vel-cmd => pid.0.command-deriv net motor.00.pos-fb <= hm2_[HOSTMOT2](BOARD).0.stepgen.00.position-fb pid.0.feedback If that works then I might then try a non-PID version of the stepgen control. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Transform Data into Opportunity.
