Hello everyone,

Recently I was assigned the task of trying to fix the Makerbot 2x printer we have for our students.

When I came in, a few components had been broken off the motherboard, so we spec'd out and replaced the broken connectors (it was just the power connector and a push connector for the thermocouple wires I think).

I managed to get it to the point where everything seems to turn on. The lights turn on, the fans start running, the Makerbot plays its jingle, and the LCD screen turns on and Displays the home menu. At this point however, the menu seems frozen. Pushing any of the buttons next to the screen has no effect. It seems to be content just running its fans and lights indefinitely. I've checked the voltages going into the board and at all the labeled test points, everything seems to be fine.

Unfortunately, when I try to connect the printer to a computer, I get unrecognized device errors. My guess is that there is a firmware issue, but as it's my first time working with a Makerbot printer, that's really only speculation. Its probably also worth noting that the printer was purchased in 2013, well before my time, so the warranty is long gone.

If anyone has any thoughts on what the issue might be, or on how I might be able to update the firmware or drivers without a USB connection, I would be eternally grateful.

Thanks in advance!
