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!
- 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!
- Park head with retract on pause and abort
- Use native functions instead of Gcode
- Loud beeps to alert user on runout
- Fix potential looping issues by using flags
- Fix "Stop failed" message on some occasions
- Raise nozzle timeout to 10 minutes
- Use continue button as reheat trigger
- Manage nozzle_timed_out variable via display
- Add PausedByNozzleTimeout flag to enter correct routine on display
- Bump version to 1.4.3
Thanks to feedback from @DerDominik I was made aware that Anycubic's default acceleration values in their source code are different from the ones they use in their compiled firmwares. Seems like insufficient torque on the Y-axis caused step loss on TMC2208 for that reason.

Thanks to some great feedback from @RolandRosenfeld I did some small tweaks:
- Adjusted auto PID tune parameters
- Replaced manufacturer PID values
- Minor changes to the readme
- Raised retraction on G26 Mesh Test
- Merged latest bugfix from derhopp
- Added latest hex files

Since a custom fan duct caused the heat block on my printer to cool down enough to have a negative impact on PETG printing, I adjusted the auto PID tune aswell as the default PID values.
Also adding a precompiled hex file of all the previous changes.
• Added auto PID tune of heatbed to the special TFT menu
•Enabled automatic saving on both PID tune commands
• Added preheating and mesh leveling commands to the special TFT menu
• Mentioned changes in readme
After getting my extruder to work reliably on a Vref of 1.100V on the TMC2208, I had to adjust my e-steps quite a bit from the original value from Anycubic. Assuming you have a TMC2208 on a similar voltage, this might work well right after flashing, calibrating your e-steps is recommended in any case.
Enable heatbed PID mode and add several tweaks
Enable PIDTEMPBED and add several tweaks
• Enabling heatbed PID tuning
• Tweaking default hotend PID
• Enhancing MMBL grid from 9 points to 25 (3x3 to 5x5 -
fair warning, leveling might take a few minutes now!)
• Increasing buffer and lowering baudrate to ensure smoother prints via USB
• Removing some redundant stuff to save memory
Thanks to @NetrunnerAT for his recommendations!

Using TMC2208 in standalone mode, I've inverted the stepper direction to match Anycubics pin layout. M110 memory watcher was removed due to redundancy and - ironically - to save memory.
