mini 5+ toolhead bltouch problems
-
I've just upgraded from a duet2wifi to a mini 5+ and a toolhead. Everything is working apart from the bltouch. It doesn't depoy when probing z.
the below code deploys and retracts as expected

M950 S0 C"121.io0.out" ; create servo pin 0 for BLTouchSo the P in your M280 should be
P0Further, the

I'm actually quite surprised that works.
Can you also check your firmware versions? M115 and M115 B121. They should both match, and should be 3.3. If not, update by uploading https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip to the system tab in DWC. It should update. Check versions again. If the expansion board hasn't updated as well, send M997 B121 to update it manually.

thanks. Making some progress..
I've added the ! to M950 and changed the pins in deployprobe.g and retractprobe.g

running homeall gives this error

figured out the last bit. I didnt need to define a pin in M574 Z
M574 Z1 S2not
M574 Z1 S1 P"121.io0.in"full config.g in case it helps someone else.
