Ok I can see the problem in the code.
The underlying probe routines don't even get separate xy/z max travel lengths.
It will take me a while to tease out the fix though.
Yeh, I've been digging but don't understand the flow, but yes if its a straight down probe, probe_down() needs to receive the contents of lineEdit_max_z and you are not saving that anywhere.
It is pretty important becsaue stright down is the dangerous one so people wil like to kep the distance low say 2mm so the probe does not get damaged.
A note on useage: extra depth need to be set to say 1-2-3mm becasue otherwise we seem to probe at the top of the material and we need to be lower than that in case there is a chamfer on th edop of the material.
If you really wanted to be cool, and I need to think about it a bit more, if there was a setting to probe straight down and then Probe XY in one move it would be great. I think that needs to be done from the corner probe (eg call straight down first, then do corner). eg we if had a Probe for height first flag to enbale that feature.
PS you might regret my help before long. I'm good at reviewing applications and seeing opportunities to map to the user experience!
(despite my best intentions, I have bent my spare probe already. Just make sure its plugged in before probing!)
