manual tool change: are you saying the pop up dialog doesn't work in sims?

I got this working today. Missing a connection and I found the answer  here

Max_travel must be set from Max XY Dist in the probe panel. I could see this when running the ini  with -d
I had it set to 50mm and the Z at 10mm. 50mm was too far for my Z so it was erroring. Eventually I twigged what was going on. Changing 50mm to 10mm fixed my problem.

The Z axis probing distance should be set by Z Max travel field.
 

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.

is there a big advantage of separate xy/z max lengths?

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!)
 

Versa probe doesn't separate max travel for xy/z - I suppose they want you to set it each time if you want it different.
They both use the same underlying code for probing - so it's complicated to make changes.

I test with a plastic tube on my probe, because I did the same sort of thing.
We should probably add a 'probe connected' HAL pin to linuxcnc.

Big changes to probing will need to go to master. It would be nice to get a consensus from the few people that use probing.

But no bugs and good docs is the highest priority for 2.9.
Thank you for the help.
