I am 99% sure this is the problem. I have a M5U and it does not like to print when in the garage during cold temps. I got the Elegoo heater and it helped a lot but I agree a Brewers belt would do the same for cheaper. Or moved inside.

What’s the go-to printer?
I'm a fan of the tilting vat printers since they apply less peeling force to the film and they're generally faster. (Prusa, Elegoo Mars 5 Ultra, Saturn 4 Ultra.) They're more forgiving on supports, which are a huge learning curve coming from FDM to resin. The Saturn has two variants, 12k and 16k. Th

Anything i should know before buying the Mars 5 Ultra?
Make sure to get protection on it because 3 months in my M5U just decided my prints shouldn’t look good anymore and elegoo support has been horrible. I’m sure my experience with it isn’t the status quo, but better safe than sorry. When it’s working it prints like a dream! Oh also make sure you have

Entry level 3D Printing
Saturn 4 Ultra (commonly S4U) in 12k or 16k is going to be the easiest printer to get started and successful prints from for a new user. The Mars 5 Ultra is the smaller version with all the same features as the 12k, just different resolution and build volume. The tilt release system eliminates 12-16

Mars 5 Ultra
I did this exact upgrade and, almost a year on, it's more hit than miss. My Mars 3 Pro was a beast and super reliable. Mars 5 Ultra requires a bit more thought and tinkering when it comes to supports and STL placement. The tilt vat does speed things up, but it creates different pull forces in the va

Can't Decide Ultra 16K or M7
Also in Aridzona. I learned about resin printers from a friend whose printer did not have a tilting-vat. My first resin printer was a tilting-vat printer. And I don't regret that for a moment. Now I have two, a M5U and a S4U12k. Each has printed hundreds of parts, possibly more than a thousand in to

Dealing/Preventing Resin Leaks on the Mars 5 Ultra/Saturn 4 Ultra due to Tilting Mechanism
The M5U includes a factory screen protector, which is under the black tape. It would take some work to get resin past the tape and past the screen protector. The screen protector is mildly pointless, because you can't purchase one separately, and if you purchase the whole LCD from Elegoo or Chitubox

First resin printer
I started with an original Mars and fairly recently upgraded to the M5U. It died in 2 weeks (wouldn't turn on) and I was able to exchange it at the retailer I got it from. I've been using Elegoo ABS-like 3.0 8k resin and the prints have been very good. The Satellite software is a mixed bag. It's eas
