I have also this issue with T R1.

After resume:

Error: Attempting to extrude with no tool selected.

@Phaedrux
I used unofficila-3.3beta from 2021.02.01 and "upgrade" to RRF3.2. Now I have sometimes this freezes.

I have exactly the same issues after upgrade to RRF 3.2. The unofficial 3.3 Beta works.

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?

No answer?

Is ther finally a solution for this error?

config-override.g doesn't override anymore the M307 H1 B0 S1.00

I have now the exact same issue.

Yes, I'm use also Duet3 with SBC.

I have also this issue with T R1.
