GCODE and GUI attempts at controlling results in “Heater heater\_chamber not supported” list\_sensors heater\_generic heater\_chamber, heater\_bed, extruder SET\_HEATER\_TEMPERATURE HEATER=heater\_chamber TARGET=50 Heater heater\_chamber not supported I’m sure I’m doing something stupid, but I can’t see it. Thanks for your help.

Additionally you have a **heater\_generic** , the tmc2209 **extruder\_stepper** and heater\_fan named **toolhead**.  
This should cause the parsing error as the last toolhead named component/object is your fan.  
The TMC stepper section only allows one name and not two.
