Enable / Disable Output when Spindle is ON /OFF

Hi,

I do have a ATC spindle that requires bearing air. For this, I can enable the solenoid via M64 P05 and disable it via M65 P05. How can I automate it so that it activates the air when the spindle is active (as I understood, every time the M3 command is run)? 
My first idea is remapping the M3 command and add the M64 in it but I do not know how to enable the spindle then in the remapped M3...

If it only needs to be on when the spindle is on,
you could do it all in hal with  single statement:

net spindle-air spindle.0.on air-solenoid-drive

(with names other than spindle.0.on changed as desired)


 

In hal, add the air output pin to spindle-on signal
No remap required.

Ah, even easier. Thanks!

Like so ( I would also like to use manually using code, thus mapped to motion pin)?
net solenoid-bearing_air spindle.0.on hm2_7i76e.0.7i76.0.0.output-11 <= motion.digital-out-05

Pretty sure this is all you need
net spindle.0.on hm2_7i76e.0.7i76.0.0.output-11
or this
net solenoid-bearing_air spindle.0.on hm2_7i76e.0.7i76.0.0.output-11

Sometimes you might need to use a timedelay on the spindle.0.on to ensure the air circuit gets up to pressure before the spindle actually spins.
