I’m a newbie… just purchased a used Ender-3 V 1.1.4. I was told it stopped working and they didn’t know why. No other details, but I found the extruder was not moving the filament. After following a few troubleshooting guides on YouTube I found the motherboard is bad. (I switched x-axis with extruder plug and found the extruder motor works. I also switched the cables on the motherboard for extruder and x-axis, same results… so, motherboard isn’t sending a signal to the extruder motor… right? I may pull the board and troubleshoot the circuit, but that’s not my expertise!!! What’s the simplest and cheapest way to replace the board. Since I’m completely new to this I don’t want to do an upgrade only to find something else doesn’t work or I get bored with 3-D printing (Ha, ha). Appreciate any feedback.
Thanks… Jerry
