Hello there,

The issue I have triggers when I try to BED_MESH_CALIBRATE.
Right at the moment the probe is about to touch the bed the MCU shuts down with the message:
“MCU ‘mcu’ shutdown: Timer too close”
The probe doesnt seem to be the problem as I can execute PROBE and DELTA_CALIBRATE method=MANUAL and it seems to work accurately, so I am wondering what else could cause this.

Thanks in advance,
Moosey
