To high ambient temperature?

I recently moved my MK3S+ (I have no mods to it, it’s stock) to a smal wardrobe. Now when I print PLA the ambient temperature goes up to 40 degrees Celsius. 

Now I’m worried, will that be a problem, like make the printer to jam/clog often or in other ways make the printer unstable?

What temperature is the “line” for stable/unstable prints? What would you say is the highest ambient temperature can be?

The printer should be OK but print quality and success might suffer.  Can you print with the door open?

Cheerio,

Print ABS and let the good times roll.  Most of us have to pay extra for that.  🤣

From the manual of the MK3S+,

Working temperature range: 18 °C (PLA)-38 °C, indoor use only

Working humidity: 85 % or less

I recently had a jam up at the drivegear, it was like a "lump"/blob, so it couldn't push the filament down.Might be my PTFE tube in the hotend is bad, but I couldn't see anything wrong with it. So it made me think if it could be the ambient temperatur in the wardrobe that was causing the problem.

I can see in my temp sensor I have put in the 3d printer space/ warderob  at the moment the problem occured was Temp 38.3 °C,  humidity: 36.3 %

From that data, it shouldn't be any problem, this is how it can look like when I print PLA, Temp 38.3 °C,  humidity: 36.3 %

38C is fine for the machine but it might give heat creep/jamming problems printing PLA, specially on models with lots of retractions. I'd say anything more than 30C room temperature starts to be risky with PLA and a stock Prusa hotend.

RE:

The machine is perfectly fine at that temp but like Artur said, PLA is very sensitive to ambient temperature and even slightly elevated temperatures already increase the risk of clogging. This does depend on the PLA brand however. Some are more prone to it than others. In any case, if you can, open the doors of the wardrobe or improve ventilation in whatever other way. Alternatively, print for example PETG which feels perfectly fine at warmer ambient temperatures. 

Mk3s MMU2s, Voron 0.1, Voron 2.4

What would you say is a good ambient temperature for printing PLA (Prusament)?

Dont care what the documents say, anything above 30 degrees C and you can start having trouble with PLA's and heatcreep.  Short prints aren't so much of a problem but 2 day prints for example, then its a different story.  You want it cool but with no drafts.  It does also depend on the PLA brand of course.  If you can arrange it to be 20-30 ambient then that's ideal.

ok, so about 30 °C. I need to see what I can do here.

is ≈40 °C  ambient temperature to high for printing PETG?

RE: To high ambient temperature?

It's OK in all likelihood, although it would be safer a few degrees below. It depends also on the PETg brand, the total time to finish the print and other variables.

I say, 40C is pretty high. Is that the room temperature of the room or inside an enclosure?.

It’s in small warderob. I can’t create a whole  and put a fan there. I open the door, then it’s 29 to 31 degrees. But then there’s the sound that can be heard loud in the whole apartment, and it feels lot louder at night.
