Hi Everybody! I am new here and sort of new to 3D printing. I have A10M and I want to use (for now) only a single filament. Some time ago I printed (more less) successfully several things and everything was working fine. Recently I updated to the latest firmware and things started to go strange. My retraction /feed gear works BACKWARDS! I mean it retracts instead of extruding and extrudes instead of retracting. How can I fix this? I don't have a previous version of the firmware to revert to for checking if this is the problem. Please help! Jerry.

Hello, if your extruder motor works in the opposite direction, you don't need to change the firmware, just change the line sequence directly to solve the problem. As shown in the figure, swap one side of the cable on the motherboard.
