Checking the probing sensor

  1. Make sure that Hotend #1 is cool before continuing.
  2. Removing the printhead lid.
  3. Push Hotend #1 upwards.
    • You should hear two soft clicks, one when pushed and one when released.
    • The hotend should be able to move freely up and down without any issues.
  4. Check that the thermistor and heater cartridge cables are not obstructing the probe sensor in any way.
