Burning hotend - Rapido
HELP. I've gone completely dumb.
at first I have a symptom that the rapido does not heat up above 220C degrees and now I have the impression that it is heated to the max, i.e. up to 350C because the filament is on fire.
it is connected to the EBB36 can bus and the thermistor is PT1000 ( two lines)
How to check whether the thermistor gives true values??
here is my config
[extruder]
heater_pin: can0:HE0
sensor_pin: can0:TH0
sensor_type: MAX31865
sensor_pin: can0:PT1000_CS
spi_bus: spi1
rtd_nominal_r: 1000
rtd_reference_r: 4300
#pullup_resistor: 4700
min_temp: 0
max_temp: 350
max_extrude_only_distance: 200
nozzle_diameter: 0.4
min_extrude_temp: 170
pressure_advance: 0.03
rtd_num_of_wires: 2
[firmware_retraction]
retract_length: 0.5
