It's heated bed also comes with ATC Semitec 104GT-2 thermistor, but everywhere, in every config of Klipper you have EPOCS thermistor as default. I ran a PID_CALIBRATE, which also was successful. The SYNC_STEPPER_TO_EXTRUDER and SET_EXTRUDER_STEP_DISTANCE commands have been removed, and the extruder shared_heater config option has been removed (deprecated on 20220210). To use this config, # the firmware should be compiled for the STM32F103xE and MKS Robin mini. The Klipper PROBE_CALIBRATE tool can be used to obtain this value - it will run an automatic probe to measure the probe's Z trigger position and then start a manual probe to obtain the nozzle Z height. If you get wrong readings but closely followed the instructions for your board, then most likely the thermistor is dead. Kinematics: Technical details on how Klipper implements motion. The application processor determines when to step each stepper motor, it compresses those events, transmits them to the micro-controller, and then the micro Hook up the BL-Touch "servo" connector to a control_pin according to the BL-Touch documentation or your MCU documentation. Unfortunately, it appears to use a different thermistor (which I suppose shouldn't be a surprise) and since I'm running Mainsail & Klipper I need to know what kind to adjust the settings since Mainsail/Klipper won't start because with the stock thermistor settings it's apparently getting way higher temps than it expects (was showing like 926 Jun 18, 2023 · What I would do is(or what I normally do to calibrate a thermistor): heat up some water to a specified temp, check it with a precise and calibrater thermometer(preferably an analog one), then put the thermistor in and measure the resistance with a multimeter Mar 6, 2023 · replace the heater cartridge and thermistor added in the configuration file verify_heater extruder and increased the default numbers.
