3.4.1 rc2 G30 turns off Z motors

I don't see any major issues in your config, but again I would ask how you are determining that the Z motor is being turned off?
The only error you've shown is the Z probe not activating.
There could be many reasons for that. -
@owend
Hi the Z motors are turning off as the bed falls down ( belt driven) -
@moth4017
Do you have a cancel.g file?
If the print was cancelled because of the failed probing then perhaps you should look at cancel.g and/or stop.g for an M84 command. -
@owend
i dind see the "cancel.g" in the console;cancel.g echo "Cancel.g " M98 P"/macros/home_max_Z"and it didnt run the Home max.g file

@moth4017 To throw my two pence in: Can the faulty behaviour correlate with sensorless homing, I.e. stall detection? That’s activated for the Z axis, as well as stealth chop mode. - Just an idea, I’m far from being an expert with this …
-
@moth4017 the only reasons I can think of why the Z motors would turn off are:
- They are being commanded to turn off by a M18 or M84 command
- The motor current is being set very low by a M906 or M913 command. For example, if M913 has been used to reduce motor current during homing or probing, and the M913 command to restore motor current to 100% afterwards is incorrect.
- The drivers have detected a short circuit condition. Incorrect use of stealthChop mode can trigger this according to the TMC22009 datasheet.
- The board has reset. On this case, all motors driven directly by the Duet will turn off and the reset reason will be reported if you run M122.

homeall.g may be different to homez.g. Can we see that as well, please?

@dc42, @infiniteloop ,@OwenD and all the others that have come up with ideas for this and my other issues re sensorless homing , i decided to go back to square one and rewrite all the macros and configs, i now have a machine that seems to be doing everything it should . so im posting all the files that i have working.
thes files are for a core XY , belt driven Z with a gearbox ratio 4:1
