How to automatically probe the tool tips:

Duet3D probe commands:

  • M585: Probe Tool
  • M574: Set endstop configuration
  • M581: Configure external trigger
  • G0 H3 Z0: H3 means stop probing when endstop is triggered and set Z0 at that point

Tool offsets are given as the offset of the nozzle relative to the print head reference point, so the signs are opposite to what you might expect because tool offsets are subtracted from the required printing locations during printing.
