My X1C is dead and I have no idea why

I was in the middle of a filament calibration when I went to look at the live video, the software said it couldn’t connect to the printer. I walked to the printer, and there was no power. No screen on, no lights in the X1C or the AMS. Looks like it only made it a couple minutes into the calibration print when the whole machine lost power.

I tried turning off and on again ( a few times while waiting a while in between), and checking the plug against the wall and the back of the machine. It all looks fine, except the printer doesn’t turn on.

I created a support ticket, but am hoping someone knows a (hopefully easy) fix here on the forum. My X1 is only about 7 months old and this is the first time I’ve had to contact support.

EDIT for UPDATE: It dawned on me that it was possible that the wall socket rather than the printer, possibly was what was broken, so I plugged the printer into a different socket on the same set of 2 sockets in the wall, and it turned on.

I am currently running diagnostics on it to try and figure out if the printer is ok, and if it may have somehow fried the wall socket.

Ever since the last firmware update I’ve been having problems with the printer, but this one was the scariest.

The symptoms you described likely indicate that the internal power supply switched off due to thermal or circuit protection. Since you didn’t mention how long you waited before experimenting, we can only guess. Most modern power supplies reset themselves after cooling down. This issue could be caused by factors unrelated to your wall power, such as a faulty internal power connection. This could be due to a loose connector or a bad crimp on a wire, causing arcing or surges from printer vibration. Diagnosing a bad crimp is difficult, as it may not show during a continuity test. Re-seating each power connector might help, but this task requires disassembling the printer and is best left to a qualified technician.

The notion of having “fried your wall socket” is particularly alarming.


If you truly believe that, you should have a qualified electrician examine it. If you believe the printer was the cause, why risk plugging it back in without verifying safety? A simple test would be to purchase a wall socket tester from a local hardware store and verify that both the polarity and ground are functioning correctly at the outlet. Since you didn’t mention your country, I can’t provide more specific advice.

Thank you.

I am in the USA.

Then if you’re in the US, and you don’t already have one, then you probably want one of these in your toolbox if for nothing else, peace of mind. I still have my first one from over 30 years ago and recall when I moved into a new house, how many outlets were wired incorrectly.

Any local hardware store likely would sell this, I even saw them one time being offered at either a CVS or Walgreen, I can’t remember. But it will tell you right away if you have a ground fault or if any of the wires are reversed. For under $10, it’s a handy little tool.

Maybe it’s on a GFCI circuit? Some older model GFCI could be a bit twitchy.
