I had similar problems with my toolsetter, and initially used an AND gate - until the time I forgot to enable it (I used a manual signal, not motion.*) and crashed my toolsetter.  Then I tried smoothing, which worked OK.  It turns out the toolsetter is a good seismic monitor, and trips when I have issues with toolchanging ;-)

However, my comment here is... have you considered using a dummy probe move to retract the probe?

Hi Andy,
I believe that the issue I'm describing is exactly the one here:
github.com/LinuxCNC/linuxcnc/issues/2926

The last comment from that issue was you asking about the motion.motion-type following motion.probe-input going high.
I've looked in the halscope and it does seem that motion.motion-type remains at a value of 5 (Probing) until deceleration is completed, at which point the motion-type goes directly to 0 (Idle). So the issue isn't that the motion type resets immediately when the probe input triggers.
I was probing using just the X axis/joint 0 when I tested this.


I'll try and find out a bit more if I can.
