Hi,
its not a issue… this time
What is the default value of:
[tmc2209 extruder]/sense_resistor
If not specified…
I ask because in Ratrig’s Klipper configuration/customization, the value of ([tmc2209 extruder]/sense_resistor) is not defined. But in some, not all SHT42 configurations that i have see, it is defined as sense_resistor: 0.11.
Until now, I had nothing defined for the SHT42, which controls the extruder motor… and it gets very hot, more than 100 degrees.
The question is if this parameter, [tmc2209 extruder]/sense_resistor), may have to do with this excess temperature, because I tried to lower the current to 0.50, which is not a very high value from what I have seen.
Also ask, I ask, to see if that default value coincides with the one that Octopus Pro has for the motor drivers. Since in the “factory” configuration, nothing is specified for that parameter.
Should I specify it?
Depends on the driver? (All tmc2209 use sense_resistor:0.11?)
