Hi William,
I do not know the right direction of the motors.

Start with standard Firmware!
I have a build a keychain.
First in black tahn in red.
2 standalone files in Cura, right click on them and set for black Ex1 and for red Ex2!
Than put the files together.

The A20T stars and all the Ex run ...

Hello together,
i got my A20T today and the first print was OKAY but all oft the 3 extruders are warm!
than i tried a 2-Color-Prinnt and the A20T used all 3 extruders but in cura, the 2 prijects are seperated to Ex-1 and Ex-2 and than put together.

tahn i tried an other firmware.

perfect, the A20T ...
