Calibrating tool offsets

  • First position the nozzle approximately above the probe - the probe will find the center on it's own within 1-2 mm.

  • The first tool has all offsets to 0 and is used as a baseline for other tools. Run TOOL_LOCATE_SENSOR to calibrate nozzle location for tool 0.

  • For every other tool, run TOOL_CALIBRATE_TOOL_OFFSET to measure the offset from the first tool.

All probing moves and final offsets will be printed in the console.

Calibrating nozzle bed probe.

  • Do the first two steps from above to ensure the probe is precisely under the nozzle.

  • Run TOOL_CALIBRATE_PROBE_OFFSET - to measure Z offset from nozzle triggering the probe to tool's nozzle probe activating.

All probing moves and final offsets will be printed in the console.
