I am trying to configure parallel port to Mesa 7I43 to 7I29. I have entered the PWM pins but it says I have not. A picture is attached. What am I doing wrong.

Does pncconf startup with all the PWMs pre-assigned to axis? that seems odd

I assigned the xyz axes. I assume the 0., 1., 2., along the left column are the three sets of pins that I should use.

I was wondering why all the unused PWMgens were pre-assigned
to axis

I think that you can continue regardless?

Possibly a pncconf bug?

Here are the screens that led to the problem. Between 3 and 4 I only set the pins that have 0:, 1:, or 3: in the column to the left. The rest set themselves. It will not let me move forward.

The problem seems to be here:
github.com/LinuxCNC/linuxcnc/blob/2b37c8...onf/pncconf.py#L3838

It seems to be a mismatch between signal names and what is being checked for.

A workaround would be to edit the file (it's Python so you can just do that) to simply set pwm = True in the line underneath the "if" and it should work.
(Definitely looking like a bug)

No joy. It is still doing the same.

Is this using linuxcnc's 7i43 firmware or something else?
What version of linuxcnc are you using?

It is not a bug. It is a moron. I did not have the 5v supply connected to the 7i43.
