@omtek thanks for reporting this, and I'm sorry that you suffered a broken nozzle.
I have created issue https://github.com/Duet3D/RepRapFirmware/issues/978 to be resolved in RRF 3.5.1. Meanwhile I have added a new entry in the Upgrade Notes for RRF 3.5.0 to say that any use of M400 in deployprobe.g or retractprobe.g or macros that they call need to have the S1 parameter added.
