Massively speed up MMU filament changes [MMU]
A series of improvements have been implemented that massively speed up MMU filament changes by up to 9 seconds. Some changes in the MMU firmware were required as well, so it is necessary to flash a new 3.0.4 firmware to your MMU unit.
The improvements include:
- Parallelized unloading filament from the nozzle and idler engaging.
- The printer does not wait for the final idler disengagement to finish to continue printing.
- Parallelized selector and idler movement.
- FeedingToFinda phase now obeys PulleySlowFeedrate with higher value.
- Optimized idler selection mechanism during filament change.
Updated default input shaper profiles [C1, C1L]
In 6.5.3-beta, we’ve fixed a bug causing input shaper configurations to be swapped on the CoreXY printers. As a result, new input shaper profiles needed to be calibrated as well.
If you have Core ONE L or an accelerometer accessory, we recommend re-running your input shaper calibration.
If you don’t have an accelerometer, we recommend resetting your input shaper profiles to defaults using the Settings → Input Shaper → Restore Defaults. If you haven’t changed your input shaper settings, the values should update automatically.
