I have also this issue with T R1.
Error: Attempting to extrude with no tool selected.
I have SBC Duet3 MB6HC with toolboards 1LC at 3.1 or 3.2
After Reset - Homing all - Tool load - Tool unload - Homing all have I a X-offset off 5mm.
I can print without problems, also tool changes. Only after the 2nd homing have I the offset.
What can I do?
config-override.g doesn't override anymore the M307 H1 B0 S1.00
I have now the exact same issue.
