Heavily modified Zonestar P802QR2 with the mcu BTT SKR V1.4 BTT display D_TFT24_V1.1.27 and the BTT CB1 controller. Everything works, It does two color prints.
Please note the users have to adapt their own values by running auto-PIDs, probe calibration and bed mesh leveling. The values for my particular printing are shown only for illustration.
