identify in HAL when Linuxcnc is doing drilling operation (G83/G76...)

Any idea if this is possible?
Motion.motion-type offers only values for linear and arc-feed.
But my goal is to activate some external hardware only when linuxcnc is doing a drill operation.
Any idea or Chance if and how this could be possible?
Thx!

A somewhat clunky way would be to run the gcode through a filter and bracket the G83,G76 with M62/M63

I lke this idea because ist just a little postprocessor modification...
Thx for this!
Any other ideas?

You can also make a filter to make the changes when you open the file.

Awesome! Great! Thx. The incredible flexibility of linuxcnc is sometimes too much "to see/know everything"

Can the requirement be correlated to specific tools? If so then you could set HAL pins in a remap code, or possibly use halui.tool-number to pick from a mux.

Hi Andy.
unfortunately not. We do Drilling-Operations with different tools. Thatswhy i am fine with the solution now:
A Gcode filter adds before G81 a M62 P0 and after G80 a M63P0.
The triggered HAL-PIN is linked to my internal MIST-cooling solution
Works perfect for me...
Greetings
Andreas

Glad you have it working.
But my suggestion with the mux would have worked for as many tools as it needed to, but the tool numbers that got special treatment would be hard-coded in the HAL file, in effect.
Another alternative would have been to add 100 to any tool number that needed the mist cooling, and then handle the differences in a remapped tool change file
O100 IF[ <_tool> GT 100]
M6 [<_tool> - 100]
M7
O100 ELSE
M6 <_tool>
M8
O100 ENDIF.
