After changing out my hot end to address a thermal runaway, I went to reload my filament and my extruder wouldn’t move. I moved the connections around on the board to connect the extruder servo to an axis connector I knew was working, and the extruder worked. This tells me it’s not the wiring or the servo, but what would cause this? Could the board malfunction like that? Could a reboot with new firmware possibly fix it?  
The printer I have is an old Big Box Pro, which has a SD card and what looks like a network connection, but no external USB connection. (however I see that the Rumba card is attached to the small screen with a USB Mini-b connector) If I need to upgrade the firmware, how is this done? Obviously I have much to learn and would appreciate anyone who is willing to help.

Hi RUSharp, Sounds like the stepper driver on the board might be the issue, since the motor works on another port. A firmware update probably won’t fix that, but worth a try just in case. You can connect to the Rumba board using the USB Mini-B on the screen and flash it with Arduino IDE.

Thank you. I’ve decided to move on to a new printer. I appreciate your thoughts.

Some mother boards have drivers (chips) that can be replaced. Worth liking into.
