Mach3 XML and Stepconfig issues.

Still pulsating that you can hear by ear.

The more I think about it Andy is probably right (he usually is). The chip you are using for your analog conversion is made for converting an encoder signal. So it is expecting the step length and step spacing to be equal.

For your direction signal replace this line.
net spindle-ccw <= stepgen.2.dir
with
net spindle-ccw <= motion.spindle-reverse

Is is still pulsing using the type-2 stepgen and the phase-a signal?

You'd also need to change this pin
net spindle-cw <= stepgen.2.step
to
net spindle-cw <= stepgen.2.phase-A

All settings as per your recommendations I can start spindle, Andy's phase = nothing as I have to edit out several lines to get LCNC started.

You should only need to change 3 lines
loadrt stepgen step_type=0,0,1 ctrl_type=p,p,v
net spindle-cw <= stepgen.2.step
net spindle-ccw <= stepgen.2.dir
to
loadrt stepgen step_type=0,0,2 ctrl_type=p,p,v
net spindle-cw <= stepgen.2.phase-A
net spindle-ccw <= motion.spindle-reverse

Will go down and test that, thanks Todd.

oh, and comment out these 3
#setp stepgen.2.steplen 250000
#setp stepgen.2.stepspace 250000
#setp stepgen.2.dirdelay 35000

Still acting as a bad two-stroke.

Can you look a the parport pin with the halscope again? We should be seeing a 50% square-wave now.
