I was trying to print a small adapter for a friend, just a simple tube 22mm outside and 19mm inside. The first test print was fine, but as soon as I cloned the part to make some more, well there my bad day started. The first layer went fine, so did the next, but then the walls would not stick, so it looked a bit like stringing. So i tried on my P1S and no problems there, so back to the U1. I tried printing something that i had printed before without any problems, but that also failed and i was getting really annoyed. I’m almost ashamed of it, but I spent the next 7 hours trying figure out wat was wrong, and I had no luck. Then I thought of something that i maybe should have done right away, i turned of the power and then back on again, and to my delight it printed with no problems, so what a day. ![17693716726562633616752180723380](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/7/2/72b4923edf2bd3a675ef7128c156ce126e5a30e5.jpeg) ---

I had the same problem. I eventually found out my printing temperature was way too high. ---

When I see this I always check the slicer preview for anything odd. Make sure your settings are correct, or just try printing with the official filament profile and stock process settings.

I tried everything I could think of, adjusting temp and so on, but something had gone wrong somewhere and I could not figure out what, only when I turned the printer off and on again, then it suddenly printed fine again. My problem is solved, it’s just if you get into trouble somehow, try turning it off/on and it may solve the problem, at least in my case it did. ---

I tried all that, the only thing that helped was turning the printer off/on, and then it printed the same part without problems. ---

Thanks for your sharing. It sounds like there’s a hidden bug lurking in there, but you can’t be entirely sure of its existence— **a true Schrödinger’s bug.** ---
