I've got the FT6 up and running-ish. I need to solder on the capacitors to the end stops. With the dual extruder touch screen, the firmware is a bit off. It actually homes towards MAX X and Y, so you have to change the direction in firmware from -1 to 1, and also swap the plugs on the board to X+ and Y+.
I can't find a way to restart the board through software, anyone else have this issue? I can access the OrangePi through my browser and log into it and add plugins, but right now I can only shut it off with the physical switch.
I had to switch the direction of the Y and Z motors, and remember to move the inductive sensor down to trigger before the nozzle crashes into the bed!
Also, I used a 50W heater in the hotend, available on AliExpress, so don't forget to run autotune on the bed and nozzle.
