- Optimize TFT code for state handling (pause, runout, ...)
- Remove multiple state booleans in favour of a single integer
- Remove obsolete filament runout code
- Increase jerk/accel
- Decrease TX buffer size
- Revert minimum segment time to factory default
G26 Gcode:
- Change Q parameter to only specify retraction length
- Add Z parameter for unretraction length
- Preserve fixed multiplier of 1.2 if Z isn't specified
- Add check to avoid implausible retract/unretract ratios
- Change default config values
Referencing #31. Thanks to @BlackMulch for the feedback!
Adjusting PWM frequencies to better match FDD8780, WSK220N04 and VS40200ATD MOSFET spec.
- Heater PWM frequency increased from 7.6294 Hz to 30.5176 Hz
– Referencing the Forward Bias Safe Area from the MOSFET's datasheets, this value should be safer.
- Use software PWM for fans to reduce whine
– The higher PWM frequency works well with the stock parts cooling fan and might allow for better control of third party fans

Adjusting PWM frequencies to better match FDD8780 MOSFET spec.
- Hotend PWM frequency increased from 488.28 Hz to 1953.12 Hz
– Referencing the Forward Bias Safe Area from the hotend MOSFET's datasheet, this value should be safer.
- Hotbed PWM frequency increased from 7.26Hz to 30.48Hz
- Use software PWM for fans to reduce whine
– The higher PWM frequency works well with the stock parts cooling fan and might allow for better control of third party fans
- M888: Cooldown routine for the Anycubic Ultrabase (EXPERIMENTAL):
This is meant to be placed at the end Gcode of your slicer. It hovers over the print bed and does circular movements while running the fan. Works best with custom fan ducts.
- T<int>: Target bed temperature (min 15°C), 30°C if not specified
- S<int>: Fan speed between 0 and 255, full speed if not specified
Thanks to @kulfuerst for the suggestion!
