It is actually a PT100 (orig new E3D Titan Aero). Connested directly to the e0thermistor input on the Duet 2 Maestro. The the thermocouple came from the config tool. If I select E3D there, then it sets the thermocouple. But doesn't matter. Even if I put in all parameters manually - it fails in the same way.
I connect the hotend thermistor to the bed thermistor input - the hotend temp was shown.
M308 H1 S1
Sensor 1 type PT100 (MAX31865) using pin spi.cs2, reading 2000.0, last error: sensor short to other wiring, 2/4 wires, reject 50Hz, reference resistor 400 ohms
Not sure, but it looks like the spi.cs2 is correct?
That is what I get for my E3D after I updated to fw 3.01. I tried for hours to solve this. But with no success...
I managed to get the heated bed running. But not the hotend.
This is the heaters config out of the config tool:
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B4092 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 Q5 ; create bed heater output on bedheat and map it to sensor 0
M143 H0 S85 ; set temperature limit for heater 0 to 85C
M307 H0 A486.1 C2320.7 D16.5 S1.00 V24.0 B0 ; PID-parameters for heated bed
M140 H0 ; map heated bed to heater 0
M308 S1 P"spi.cs2" Y"rtd-max31865" ; configure sensor 1 as thermocouple via CS pin spi.cs2
M950 H1 C"e0_heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M143 H1 S265 ; set temperature limit for heater 1 to 265C
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
Any suggestions? Somebody?
