Possible Solution to No Trigger After Full Z Movement

[wd5gnr]

Background: I can always get a good print the first time, but subsequent prints often produce message during probing: No Trigger After Full Z Movement

I noticed that it seems to be intermittent but never on the first print. I tried manually levelling the bed and a variety of other things.

Then it occured to me. Perhaps the KAMP adaptive probe mesh was staying in force and causing problems, especially with probing elsewhere on the bed outside the original probe area (or maybe inside? not sure).

I added BED_MESH_CLEAR to the end of each print. So far this seems to work. Since it is intermittent, it is hard to say for sure, but I have never been able to pull of 4 or 5 prints in a row without the error in the past. It seems like KAMP should clear the mesh before probing, or maybe it is G28 or some other trigger. Hard to say.

Not sure if this is a real fix or not, but if you are fighting the same problem it can't hurt to try it.

Take a look at this option too https://wiki.zmod.link/FAQ/#no-trigger-on-probe-after-full-movement

Thank you. I had tried both of these.

I added a grid clear before removing the grid, and this is also written to the console.
Test on versions:
1.7.0-68 - 5m
1.7.0-134 - 5x
