Version 6.6.2

10.07.2026

Improvements

  • Adjusted the nozzle cleaner origin position and fixed handling of nozzle cleaner offsets during parking moves.
  • EEPROM-stored nozzle cleaner offsets are now automatically adjusted after the update, eliminating the need for nozzle cleaner recalibration.
  • Adjusted the tool lock move distance for improved tool pickup reliability and reduced risk of filament being unintentionally ejected from the extruder gears.
  • Added a new option in the Tune menu for fine-tuning the nozzle cleaner X offset.

Fixes

  • Fixed bumping into the waste bin after an MBL failure.
  • Fixed an issue requiring tool removal during Dock Calibration even when no tool was loaded in the head.
  • Fixed support for older xBuddy revisions with inverted pins (early MK4 converted boards). (Credit: ScottKolo)
  • Fixed selftest gray buttons not updating after dependencies were met.
  • Fixed incorrect feedrate when loading PLA after FLEX material.
  • Fixed an invisible Abort button on the Y-axis Input Shaper selftest screen.
  • Fixed Tool Offset Cyphal communication not being reinitialized after board reset.

Version 6.6.1

02.07.2026
  • Improvements
    • Lower the print bed when a tool is unknown or lost, allowing the user to safely remove the print.
    • During Dock Calibration, users can now choose between KeepCalibrate, and Invalidate.
    • Added an  flag to skip temperature stabilization.
  • Fixes
    • Fixed spontaneous INDX Head resets.
    • Fixed incorrect tool assignment after a REDSCREEN reset. The printer now saves the currently selected tool.
