Firmware for ender 3 pro stopped printer
Can anyone help me? I have just installed a bl touch to my ender 3 pro but when I update my firmware it doesn't want to home up and I can't move the axis now. I reinstall earlier version and they move. I have a v4.2.2 board and I have connected the red plug to the z axis on the motherboard board and used the extra board to reconnect screen plug and bl touch power.
