Z-probe triggers way above table during HOME ALL
-
@phaedrux i have the offset Z trigger height set to zero for testing. What should the X-Y settings be for the G31? isnt it center of my build plate?

@billsrf The X and Y values for G31 should be the distance of the probe from the nozzle. Just as the Z value is the distance from the probe to the nozzle tip in Z.
If the probe is to the left, the value will be -x.
If the probe is to the right, the value will be +x.
If the probe is to the front, the value will be -y.
If the probe is to the back, the value will be +y. -
my BED.G looks like it is missing a lot of information now for some reason. 0_1555961191732_bed.g
-
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
-
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.
-
Is the sensor on the IR probe dirty or damaged at all?
-
@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
-
@phaedrux I have another Duet3d wifi board, I am going to swap it out in the morning and reload my firmware and see if that does it
-
Can you post your config.g as it is now?
-
-
-
That all looks right to me.
Do you have anything weird in config-overide.g?
-
-
That all looks fine as well.
