Can you try using Hal Scope to watch the parport.0.pin-06-out and parport.0.pin-07-out pins?
Ask if you need instructions how to do that.

Wait, just had an epiphany. Duh, I think we forgot to connect the enable for the spindle's stepgen.
Add this line to your hal file.
net spindle-enable <= motion.spindle-on => stepgen.2.enable

Pin 7 is not changing direction, pulses only on pin 6 for steps and 7 to go high or low.
How to change this?

The way I understood what you wanted, pin 6 should get the clockwise pulses and pin 7 should get the counter clockwise pulses. Is that not what you wanted?

If you want all the step pulses on 6 and toggle a direction bit on pin 7. it is as simple changing one parameter value and changing a couple of pin names.
Change these lines:
loadrt stepgen step_type=0,0,1 ctrl_type=p,p,v
net spindle-cw <= stepgen.2.up
net spindle-ccw <= stepgen.2.down
to
loadrt stepgen step_type=0,0,0 ctrl_type=p,p,v
net spindle-cw <= stepgen.2.step
net spindle-ccw <= stepgen.2.dir

Thanks Todd,
will try this tomorrow. It seems clear now what does what.

Problem was xml import and also no way to set parameters in the Stepconfig, only CW and CCW.
This is a learning curve for me, also that English is not my native language so it gets misunderstood.

I´m sure other issues will emerge but I am eager to learn.

Cheers
Bengt
