Thanks to Anders Sahlman and Fox Ies in the Facebook group for their hardwork in getting Marlin 2.x and figuring out UART mode for the HiSpeed FLSUN board.
Select the file you want to use and rename it to
Robin_mini.bin and put it on your SD card, then insert it into your printer to update the firmware.
This branch is updated to work with the latest PlattformIO release and is based upon the official
bugfix-2.0.x branch. Future firmwares will be updated as progress is made there and the changes are merged into this
repository, when new firmwares are built and provied you will see which date and CommitId from the official Marlin repository it was generated on.
To build the firmware yourself, you need Visual Studio Code with the PlattformIO extension. Once setup, make the changes you want and from the PIO tab build either
env:mks_robin_mini after you made the applicable changes in
configuration.h depending on which board and settings you use.
Different versions of Firmware for the FLSUN Printers. For TMC2208 on the HiSpeed Board you need to do hardware modifications. Follow this VIDEO.

UBL Calibrationsection for more details)
Below is the general steps I did to get a good Bed Level Calibration done, further documentation is available here. Alternativly you can setup the Plugin mentioned below for Octoprint to make it easier/faster.
G28 ; Home XYZ. G29 P1 ; Do automated probing of the bed. G29 P3 T ; Repeat until all mesh points are filled in and there are no empty values (dots) displayed. G29 T ; View the Z compensation values to verify that all looks good. G29 S1 ; Save UBL mesh points to EEPROM. G29 F 10.0 ; Set Fade Height for correction at 10.0 mm. G29 A ; Activate the UBL System. M500 ; Save current setup. WARNING: UBL will be active at power up, before any G28. M420 S1 ; Activate & Load UBL with validated Mesh M501 ; Verify that UBL is loaded and active.
As per the documentation here I also added
M420 S1 in Cura under Printer settings in the Start Code section, also mentioned in the FB post.
For LA follow the steps here, I've added the LA configuration in my start code in Cura after the Mesh Load mentioned above. This resource is also great for generic calibration of your printer.
I've found that following and doing a Flow Rate calibration per material to really improve quality. I've followed this guide from E3D with good results.
I've used this retraction test once the flow rate has been set, focusing on three settings. Retraction Distance, Retraction Speed and Temperature.
I usually round of the "Per Filament Calibration" by printing the following tests:
Below is a list fo great plugins for Octoprint that I can recomend checking out.
