Probe Offset

Probe offset

Before being able to print, it is nesacerry to calibrate your probe offsets. This procedure differs depending on whether you are using the OptoTap Sensor or an Eddy current sensor for probing.

[tool_probe] example.
    [tool_probe T0]
    pin: NHK0:gpio10
    tool: 0 # change to the index of the tool. 0, 1, 2, etc.
    z_offset = -1.05 # Needs to be calibrated. More positive = More Squish
  1. Ensure that your [tool_probe] section's z_offset variable is set to 0.
  2. Home the printer with G28.
  3. Run QUAD_GANTRY_LEVEL.
  4. Run G28 Z.
  5. Run PROBE_CALIBRATE.
  6. Change the z_offset variable in the tool's [tool_probe] section.

SAVE_CONFIG

Because klipper-toolchanger-easy reroutes probe to each tool object, when you run SAVE_CONFIG it saves the values to [probe]. Having a [probe] section in your config while also having [tool_probe] will cause issues with Klipper. SAVE_CONFIG should be avoided.

If you do save the values, you will need to move the offset from the bottom of printer.cfg to your tools [tool_probe] section.

Set the probe offsets as per your sensor's documentation.
