The general approach when using one parport pin to drive multiple
motion controller pins is to have the one pin drive a single signal
which then connects to multiple pins. One pin cannot drive multiple
signals, each of which drives a single pin.
Seems really confusing to me. Is there a specific reason why a single
pin can't drive multiple signals?
Yes, to avoid confusion :)
The point how it wors is that you use one single signal to drive more pins
like this:
newsig limit-home bit
linksp limit-home parport.0.pin-10-in
linksp

Gentlemen,

Jon Elson - thank you very much.
John K. I should be able to find out about the handwheel over run
this weekend.
Many thanks

I had read the manual about the axis.N.index-enable. I had tried

Looking at the code, I see that older versions of the PPMC
might not export the index-enable pin. If you load the driver
and show pin ppmc.0.encoder.02 shows an
