How to interpret Trinamic driver continuous debug reporting?
In the Marlin source code I found the function responsible for the report logs: report_polled_driver_data in Marlin/src/feature/tmc_util.cpp.

The values indicated appear to be:

&lt;Axis&gt;:&lt;PWM scale&gt;/&lt;Current scale&gt;/&lt;StallGuard&gt;|&lt;Flags&gt;|&lt;OTPW count&gt;


Where possible flags are as follows (where “debug” indicates that they only appear if TMC_DEBUG is enabled):


E: Error
O: Over-temperature
W: over-temperature pre-Warning
G: stallGuard (debug)
T: stealthChop (debug)
I: standstIll (debug)
F: otpw Flag
