I am trying to commission a Duet 0.85 on a Wanhao I3 . The bed heats up fine however I can't get the Extruder Heater to heat up. I suspect I have a config problem rather than a hardware problem.
The temperature readings in Pronterface are showing T:B21.9 which reading thorough posts on here is showing an error code for the Extruder heater. I have checked the resistance of the thermistor and cold it is showing 180k ohms.
My config file is for the tool 0 as follows
M305 P0 T100000 B3950 R4700 H0 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
M305 P1 T100000 B4388 R4700 H0 L0 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction
M307 H0 A193 C719.9 D8.7 B0 ; bed heater settings
M307 H1 A219 C128 D13.9 B0 ; extruder heater settings
M563 P0 D0 H1 ; tool 0 uses extruder drive 0 and heater 1
G10 P0 S0 R0 X0 Y0 ; set tool 0 temperatures and offsets
The heater is connceted to Heater 1 as is the thermistor
Has anybody any idea what I can try next ?
