Well, looks I'm answering my own question :mrgreen: So, problem solved! Reason was not temp sensor wires nor tempsensors themselves. I disassembled whole electronics and everything was as supposed. So, back all stuff and kept reading this forum. I wondered few people asking about ulticontrollers menus... -Aha! No such menus for me. :arrow: My firmware was very old. So uploaded Marlin and since then printer has been working as charm! :-P

Hello You all, I'm new for 3D printing, but have a bit knowledge of electronics. My problem is as many of yours, printing stops suddenly, with no visible reason. My print lasts 6 hours, but haven't finished once. Have tried 9 times, no gcode changes and printing stops in different phases. BUT -when printer stops printing, both temps reset to zero and ulticontroller reads DWELL.... instead of printing... This happens allways when printing stops. I've put fans on every motor and one extra under the machine. I have even checked temps with thermal cam, nothing wrong with those. All motors under 30 degrees celcius. I'm printing from SD with heated bed. Bed has it's own power adapter so it shouldn't hazzle anything. So does anyone have knowledge on how is the text DWELL... displayed or what is the cause of that? I found a thread where someone wrote it could be G4 command in gcode? There is no G4:s in my code. I'm very confused with this :???:
