Extruder stops working and then weird messages show up in serial

Hi there,
I've got a printer that has a problem with the extruder stopping during a print. When I take a look at the problem, I find a bunch of messages in the serial output that look like

X:102/11/-|I| Y:70/10/-|I| Z:36/9/-|I| Z2:33/9/-|I| E:0/0/-|IF|

I tried to find some info on these but I can't decypher what they mean. I would speculate that the F next to the E output means the extruder has failed, and maybe that 0/0 means it is at position zero.

Can anyone help me understand whats happening?

These message are tmc stepper driver debug lines. You have TMC_DEBUG enabled.

Its printed here [github.com]

You shouldn't have this enabled in a production machine...

TMC_DEBUG is fine to have enabled, it just increases the verbosity of some output. The setting that is resulting in the above messages and is not recommended for production systems is MONITOR_DRIVER_STATUS which continuously polls the drivers for status.
