M303 E-1 Bed Pid Fails #3

Closed dcs3473 closed 3 years ago

dcs3473 commented 3 years ago

When trying to do an M303 E-1 S? (any temp) fails with a message of...

Send: M303 E-1 S50 U1 Recv: PID Autotune failed! Temperature too high

Doesn't matter what temp you try, 50, 60, 70 they all fail.

This is caused by a bug in Prusa's version of Marlin: https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/798

The workaround is to use E-2 instead of E-1, e.g. M303 E-2 S50 U1.
