Extruder Temp Of the charts
I have a new hotend from BTT , and there is no preconfigured file for it.
The extruder temperture senor is off the charts.
I get the error "MCU 'mcu' shutdown: ADC out of range" IOF I exclude the sensor_pin it wiil start but I have the temperture at 277°.
I'm using a Btt42 and it connected to the TH0, I tried using ^toolboardPA3" instead of e_sensor_pin but it says it can not find that pin.
In the manual the pin is PA3.
I put in Overrides this: max_temp: 350 rotation_distance: 3.433 full_steps_per_rotation: 200 filament_diameter: 1.750 max_extrude_only_velocity: 60 heater_pin: e_heater_pin sensor_type: ATC Semitec 104GT-2 sensor_pin: e_sensor_pin min_extrude_temp: 190 min_temp: 0 max_temp: 350

Do you know what type of sensor it is? It could be that's it's a different sensor causing wrong values.
I not sure but I tried almost all of them.
What hotend is it?
For the th0 of the ebb you need to use: toolboard:e_sensor_pin, otherwise it will expect to be on the octopus board th0
Its a BTT Terminator
If I use toolboard:e_sensor_pin I get a "MCU 'mcu' shutdown: ADC out of range
This generally occurs when a heater temperature exceeds
its configured min_temp or max_temp." Which I would I think is because its reading the temperature as 277° maybe.
I think this maybe the sensor HT-NTC100K Thermistor
Model: HT-NTC100K thermistor temperature sensor components,which have 1M & 2M cable.
Specifications: Negative Temperature Coefficient (NTC) Thermistor
Model: XNT000004
Temperature measurement head size: 3 * 15mm
https://www.klipper3d.org/Config_Reference.html#temperature-sensors look at the common thermistors section
I'm still do not know for sure what type it is, I' waiting fro a replay from BTT. My other problem if I use e_sensor_pin the MCU shuts down I tried toolboard: PA3 which is the pin on the EBB, klipper will start bu tem is always off at 277°
It seems to be a pt100 thermistor, then you need a max31865 chip on the ebb42. Maybe you can disassemble it and change the thermistor to your previous one
I have the MAX 31865 my hemera worked fine with the preconfigured extruder in RatOS. Its this new one giving me problems, I fixed the Biqo mini probe, the neo pixels and now working ont the runot sensor. I can not test anything ntil I get tje extruder to work.
You need something like this:
sensor_pin: EBBCan: PA4
spi_bus: spi1a
rtd_nominal_r: 100
rtd_reference_r: 430
rtd_num_of_wires: 2
Also check your jumper settings see, https://www.dropbox.com/s/ffl4m7txx41ptyu/BigTreeTech%20EBB42%20connections%20information.pdf?dl=0
Thanks for your help. I have this
[extruder]
max_temp: 350
rotation_distance: 3.433
full_steps_per_rotation: 200
filament_diameter: 1.750
nozzle_diameter: 0.400
max_extrude_only_velocity: 60
heater_pin:e_heater_pin
sensor_type: EPCOS 100K B57560G104F
sensor_pin: toolboard: PA3 #e_sensor_pin
min_extrude_temp: 190
min_temp: 0
max_temp: 350
pressure_advance: 0.06
control: pid
pid_Kp: 21.527
pid_Ki: 1.063
pid_Kd: 108.982
All my pins on the toolboard are toolboard: XXX and all are working even the runout senore and motion sensor
only the temp not woring
and the sensor is set to a two wire NT100
You still don't have the max config ant the pt100 settings
That's your issue
?
ant?
Typo😋
😀
I have the max and min temp set
