Hi I am new to this forum. I am in the process of upgrading a Tronxy X3a printer to a dual extruder setup. In doing this I have changed the mainboard from the melzi 2.0 board to a creality v2.2 board. When I run my printer I flashed the firmware to recognise the dual extruders but when I move the x or y axis they move one way but not the other. z axis seems to work correctly but not the x or y axis. I have retested the cables and stepper motors on the melzi board and a Arduino nano board I have. Can anyone suggest what may be the issue. I have also tried a second creality board with the stock single extruder firmware with the exact same result. Any advice would be appreciated.
