Prevent spindle start if a certain tool is selected?

Is there any way to prevent the spindle from starting (via any possible mechanism like M3/M4 or clicking spindle start buttons in the UI) if a particular tool is selected (e.g. my Haimer probe)?

If the probe is wired with the contact in a normally closed mode, you can use the probe signal to interlock the spindle enable.
This way, when the probe is plugged in, the spindle cannot start.

there is even a HAL pin for it:

spindle.N.inhibit - (bit, in) When this bit is TRUE, the spindle speed is set to 0.

i'm actually trying to use spindle.0.inhibit right now in classicladder and the spindle is still coming on even with it set to true. I'm using a sim, though, so i'm not sure if that makes a difference.

okay, i see it now. when i use halconfig to check out my spindle.0.on, with the inhibit circuit, it doesn't turn on.

Hi

I actually facing the same things i like to make spindle impossible to rotate if touch probe NPN NC is dected as connected, i have also think about using toolnumber or using both.

For now i dislike the spindle.N.inhibit because they work like a pause so spindle M3 M4 are not canceled.

Beter imo to cancel operation than only lock.

I Have for now do nothing for this but i use a similar scenario from my toolchanger using this signal but i did not remenber if this stop only gcode execution or also the spindle.

net tool-program-abort toolchanger.program-abort => halui.abort

Well i think about using a logic like this

if Probe.input = 1 and (spindle.0.on or spindle.0.orient or Tool =1)
Then toggle halui.abort and display warning to user

I do not think the clasicladder is the way of doing this, hal is better in my opinion.
Spindle has another pin that should be possible to use
spindle-on
and
motion.spindle-on
Pulling that down should disable spindle.

Well i think this is a possible dangerous way to do this using only bypass for spindle-on because if you now remove the probe the spindle start directly

motion.spindle-on is imo not the best option, for me the best is use halui.abort : machine stay on and ready for next things vs machine is like closed. (and if you try to send message to user after motion.spindle-on altering to 0 this not possible.
