Z-probe triggers way above table during HOME ALL

Phaedrux

It looks like your bed.g is currently setup to just do a mesh grid compensation run.

@phaedrux ok, i will measure the offset and change that in the G31 in config.g

If I am not using a bed compensation. Why would that be making my trigger so high off my build surface? It moves down about 20 mm then triggers during home.all. But, if i do a home.z afterwards it moves to the correct trigger height and it is ready to go

Phaedrux

Have you gone through these steps?

yes 9 times. I will change the offsets and then go through the probe set up again

@dc42 went through the same set up process as described in test and calibrate Z probe, same results as before, it moves down 10 mm then triggers then stops. I did nottice, as it is moving towards the X-Y home position, the IR sensor flashes 3 times like it is just initialized. Never done that before either.

Tried running a G29 and this is what I am getting back now. I have never had this kind of issue with my duet3d before. its triggering during moves. 0_1555968974806_G29 Probing.JPG

Is the sensor on the IR probe dirty or damaged at all?

Billsrf

@phaedrux No, i have even swapped it out with a new probe and it does the same thing!! I am baffled!!! to say the least. As you can see it won't run a G29 anymore either
