I have a multimeter, I'll check it when I get home. I'm really hoping it's just a faulty wire, I'd rather not tear apart my teachers machine.. Thanks for the tip

One last thing that I should have mentioned. Electronic parts will normally have information on them that you can use to identify what they actually are so you can get a schematic or at least know who might give you answers. Things that help are the FCC ID which is mandatory (will tell you who made it or who holds the license at least) and any serial, revision, etc. numbers silk screened on the boards your working with.

I was hoping someone else with more experience would answer you, but since they didn't...

You need a $6 digital multimeter from Harbor Freight or where ever cheap tools are available to buy where you are. The bed will have two wires going to it from the electronics. Test for 12 volt DC when you've turned the bed heat on at first the connection by the bed and next at wherever they plug into at the "controller" board end. If you find no power at either place, just check that whatever the "controller" board (could be ramps, or whatever I know nothing about a Cube) is plugged into has power going to it. If the controller has power, I'd bet it firmware. If it doesn't, the multimeter has a decent shot at telling you what has failed so you can replace it.

I just need to know if there are wires I should check that are pretty universal on most 3d printers

Hey guys, I know this is unrelated to this forum, but I can't seem to find one that this would go in. Plus, I feel like everyone on this forum know what they're talking about. Here's my situation:

My professor lent me his cubify cube over the summer. His heat bed was not heating up when he gave it to me. I realized that he had 2nd generation cube firmware installed on a 1st generation cube. After talking to their support team, they had me downgrade the firmware using their method this bricked my teachers cube. They refused to help after that and ignored all of my emails after that. Worst company ever. After a few weeks, I managed to get the 2nd gen firmware back on the cube. But I don't know if the heat bed issue is a firmware or hardware issue. Is there a way I can yes the hardware, maybe with a tester light?

Any suggestions?
