Servo spindle via step and dir

Not sure but there a few older threads about this:

forum.linuxcnc.org/49-basic-configuratio...663-spindle-step-dir

So looks like you will need to set up a stepgen in velocity mode. For that you might need to edit the hal file directly.

Here is a more recent thread:
www.forum.linuxcnc.org/38-general-linuxc...ike-a-spindle#211162

Looking at your files it seems you don't have anything set up for a spindle.

I doubt stepconf can create a config for a step/dir spindle but the easiest maybe to use stepconf to create a config with a pwm spindle and then edit the hal file to connect the spindle velocity command to the stepgen input.

I'm not used to parallel port setups so this will not be a detailed how to:

This should then give you a 'stepgen.4' which then you will need to connect to the spindle signals:

net spindle-vel-cmd-rps-abs <= spindle.0.speed-out-rps-abs => stepgen.4.velocity-cmd

If in doubt please post your ini and hal after you have created the config with the spindle. There might also be somebody else coming along with more experience in how to set this up.
