Printer stops printing
Hi. I bought a new MK3 i3. I printed the proverbial frog and small cubes for calibration and all went well. But when I tried to print a 12 hour job, the printer went dark after about 85% completion and stooped printing. I turned it off and back on and it worked again. A couple of days after this, I tried to print a 4 hour job and after about an hour it failed again.
I contacted Prusa customer service and they are telling me that the room where the printer is must be at 22º C or more to work.
Any idea why?
Regards
Luis

If someone tells me I need X to get Y - I will ask them for a reason.
If I ask someone else, then I have to retell the entire story from the beginning to relate all the facts that lead to the answer.

Re: Printer stops printing
Well,,, I did contact them using the chat. I waited for a looonggg time and when somebody finally came over, I wouldn't get any answers. It was mute. Then I sent an email and waited... and waited... and waited... until I finally sent another email. Still no answer. Then I sent another one and finally I got a reply. After 6 days. And after asking me what was the room temperature at which the print was made, to which I replied it was around 18ºC, they told me that it should be at least 22. I asked why and they say "Whole printer has to be in warm room. If not, it will have problems with preheating and give you errors".
I'm just asking the community if you agree that this may be the problem. I'm new to 3D printing and it does't seem to be possible that a preheating problem would manifest itself after 10 hours of printing.
Re: Printer stops printing
18c should NOT be an issue; but a room that cycles 10 to 20 will cause you all sorts of print problems. I also seem to recall there is one feature somewhere that won't work at 15c or less ... I think it is hot end related to a MINTEMP error. A simple search for threads got this.
But seems you are having issues printing. Post up a photo of what you are concerned with and explain how you got there. We can try to help... lol. For example" "It printed 4 hours then failed." is a not-so-useful question. I'd ask if anyone came into the room and turned off power while you were sleeping. So try to be helpful as you ask, fill in info that might be relevant. Was the printer idle when you came back? Was there any error message displayed? Was the printer showing print Complete? Have you checked the crash log? Are you printing from an SD card or via Octoprint or Simplify or Cura or ??? And filament brand, type and profile are starting points to add along with what it was you are printing. And a photo is priceless for figuring out what is happening.
Re: Printer stops printing
In winter my thermostat is set to 16.1 (61F actually, because ‘Murica!) I haven’t had a print fail due to mintemp.
Now, I have accidentally left the printer on overnight NOT printing, and come down in the morning to a MINTEMP error on the display. I’ve also heard stories from others who have the printer in a cold space, and have to use a hairdryer to get past the initial error, but once it starts heating, it’s fine.
I’m wondering if you might have an intermittent connection in one of the thermistor wires. If the temp reads 0, I’m pretty sure it’s an instant stop.
When someone asks you if you're a god, you say, "YES!"

On one of the occasions where the printer went dead, I opened the box and probed the cables coming from the PSU with a multimeter. The voltage was zero on both. So the problem is obviously on the PSU. After 5 chat sessions with Prusa costumer services, someone finally decided to send me a new PSU. Thank you for your answers
Re: Printer stops printing
sounds like your power supply is hitting thermal overload and shutting down; it would need to cool down before it turned back on.
Replacement should get you all squared away.
