Hello to you all,
I have an Ultimaker 2+ that I bought in 2017 brand new. During all this time it has worked perfectly, considering the intensive printing sessions it has been subjected to. A year ago, I started to print less with it, with some breaks of a few weeks in between, but I always tried to print regularly, even if it was just a few small things, so that it wouldn't stand still for too long.
The problem started this summer. I started to print some small warpaints racks and the prints started to stop randomly at different points of the print, usually always at the end of the first layer or the 2nd layer.
Since then I have tried everything. Obviously, my first thought was that it was a problem with the power supply or plug. So I got a new power supply that I borrowed for testing and changed the printer's plug and electrical phase. It was still shutting down.
After that I factory reset the printer, updated Cura and tried several files made with different versions of Cura that had previously been printed several times and correctly. Same, shutting down.
I then tried several SD cards in case it was the one I was using that was going wrong. Nothing, all exactly the same with the same failures.
I still think it's a matter of the power supply connection to the main board. Sometimes, depending on how the cable is positioned, it seems to work and print perfectly, but I still don't know the correct position so it never fails.
I have also tried printing with the heated bed off, in case there was not enough power for some reason, although the printer has been in the same place, under the same environmental and electrical conditions for 2 years.
I'm not going to deceive you, I'm getting a bit desperate because I can't think of any more ideas. I've come to the conclusion that it's the main board that is failing, but I'm not 100% sure because I don't know how to do more tests.
Has anyone had something similar happen to them or can you think of what might be going on?
Kind regards,
Annana
