Option 'pullup_resistor' is not valid in section 'extruder'
✅SolvedErrors✏️CustomizationBoards
I am using the MAX31865 for temperature sensing of the hotend. It is not compatible with pullup_resistor. The problem is that this option is in RatOS.cfg. If I edit it to remove this line, it boots till the next time there is a cold start, when it is back. Can I undeclare this in printer.cfg? Or, how do I edit the template to fix it permanently?
My printer.cfg: [extruder] dir_pin: toolboard_t0:e_dir_pin # Add ! in front of pin name to reverse the direction of extruder rotation_distance: 4.63 # Orbiter 2 default sensor_type: MAX31865 sensor_pin: toolboard_t0:PA4 spi_bus: spi1 rtd_nominal_r: 1000 rtd_reference_r: 4300 rtd_num_of_wires: 2
This works as long as there is not pullup_resistor line in the [extruder] section of RatOS.cfg
Solution
Thanks TheTik. I solved it by not picking Rapido UHF Plus. Instead, I picked the Rapido UHF with the 104 thermistor. This then leaves out the pullup_resistor line from RatOS.cfg. I put all the necssary lines for the use of the PT1000 thermistor with the MAX31865 toolboard chip in printer.cfg. This solved the problem.
