                  Version 6.6.3

                  20.07.2026

                  Summary

                  • Improvements
                    • Improved head LED behavior by synchronizing tool LEDs with the printer state and matching the status indication used by the heated bed LEDs.
                    • Added Nozzle Cleaner Y Offset adjustment to the Tune menu for easier calibration directly from the printer interface.
                    • Added ringdown decay information to the Sensor Info screen for improved diagnostics and troubleshooting.
                    • Improved synchronization of loadcell samples between the toolhead and xBuddy, increasing the robustness of probing and calibration procedures.
                    • Optimized motion step calculations to reduce the risk of layer shifts during printing.
                    • Streamlined hotend management logic to improve maintainability and reliability.
                    • Reduced calibration time by skipping temperature residency during tool offset calibration heating.
                  • Fixes
                    • Reworked nozzle heater self-test validation to use thermal model evaluation during heating, reducing false self-test failures caused by minor deviations in heating performance.
                    • Added validation of INDX coil current during heater self-tests to detect abnormal nozzle behavior.
                    • Updated INDX nozzle thermal diagnostics to leverage thermal protection results for more accurate fault detection.
                    • Fixed an issue where hotend thermal errors could be reported even when no nozzle was installed by verifying nozzle presence before triggering errors.
                    • Fixed the Tool Change button incorrectly opening the extruded filament submenu.
                    • Fixed an issue where an uninitialized nozzle temperature was displayed as 15 °C in the footer.
                    • Removed a redundant cooldown check from the nozzle cleaner calibration process.

                  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 Keep, Calibrate, and Invalidate.
