you need to net the pins with a name, so something like:
net external-start hm2_7i76e.0.7i76.0.0.input-22-not => qtplasmac.ext_run
net external-pause hm2_7i76e.0.7i76.0.0.input-23 => qtplasmac.ext_pause
net external-stop hm2_7i76e.0.7i76.0.0.input-24 => qtplasmac.ext_abort

Thanks.
where does the name behind net come from?
Can I freely choose?
I see pin and signal are swapped around and arrow is in opposite direction is this just a different way of writing?

If you think of a HAL net as electrical wiring then the signal name is the name of the wire.

It is the signal name.Thanks.

Yes, for the signal name.Can I freely choose?
Yes, that is just my preferred style.I see pin and signal are swapped around and arrow is in opposite direction is this just a different way of writing?

Thanks it is working now.
So basically it is similar to a variable in programming. Does a signal actually get stored in memory and passed on to a pin?
So I was wondering,
pncconfig nets the signal from my switches. In the Hal file. So for simplicity would it be possible to pass it on directly from net to the qtplssmac pin in the postgui.hal ?

It is stored in the sense that HAL has access to the signal name as does the HAL Python interface.Thanks it is working now.

You could remove the connections from pncconf and do them all manually in a postgui hal file. Hopefully pncconf will be able to handle it completely in the not too distant future.pncconfig nets the signal from my switches. In the Hal file.

Thanks for the info.
It will be nice if pncconfig can handle that in the near future but I also understand that people work very hard to develop and improve Linuxcnc.
and I am very thankful for that.

I have been thinking of adding a laser cross to the machine.
Did a search on this forum. But did not find anything. If I missed it please point me tho the right thread.
My question is how many watts that you can see it nicely. Are there any safety issues for eyes?
Are those cheap ones you get on aliexpress ok?

How do you power it do you have a separate power supply?
Does it need a resistor ion series?

I use a cheap adjustable "buck converter" which is supplied from the 24V supply.
