Upgrading from Mars 2 to maybe a Saturn 3 ultra. Advice?
Because the non Ultra has better UV uniformity (light). The Ultra can also have bad castings in the build plate head and z arm that can prevent you from leveling it. The non Ultra comes with nFEP/PFA release film, while the Ultra comes with ACF. ACF causes fine vertical lines to appear on smooth sur

how reputable are elegoo printers?
I had a Saturn 2 that was a similar lemon. Their earlier ball joint levelling just never worked well on anything large. My Mars 1 was great, Mars 4 had the screen go bad 4 weeks in (Elegoo did send me a replacement but it took almost 5 weeks on the slow boat so I bought a different printer anyways).

Mars 4 Ultra build plate does not fit in Mercury version 2.0
I meant Elegoo. I was using speak to text lol. And yeah it barely fits in, even at an angle. That washbin clearly isn’t meant to be used with the Mars 4 Ultra. Even though the bundle advertises 2 ways to clean (model separate, and model on build plate).

What eldritch horror did I just print?
this is 100% the AA bug. This either happens 50% of the time when trying to use AA with the .goo format on elegoo printers, or about 1% chance when using AA in .ctb or for non elegoo printers. If you have saturn 4 non ultra, mars 4 non ultra, or mars 5 non ultra. You are locked into the .goo format,

Small cracks/pinholes appearing randomly on my resin prints – what could be causing this?
Elegoo Mars printers. Though looks like the Ultra 5 is maybe $60 cheapest via amazon. Though Elegoo themselves seem to sell a regular Mars 5 screen for $40 via their website. Though looks like some sellers I see popping up are definitely trying to price gouge for replacement LCDs.

Can't figure this out.
Dead pixels on your uv screen. Happen this before on my Elegoo Mars 1.

I build an iOS app like ChituManager
Hi! The app is still working, and I’m still developing new features for it (including Canvas support for the CC1).Is the Mars 4 Ultra connecting to the app? As far as I remember (sorry, I don’t use the Mars 4 Ultra anymore), both the Mars 4 Ultra and the Saturn 3 Ultra don’t allow browsing files or

Getting back into 3d printing
I have that printer. It uses a proprietary format for the files it can print, so slicer choices are limited. I like lychee slicer. Also, I didn't like the resin vat that came with it for various reasons (one of which being that fep film refills are hard to find and a bit expensive). If you feel the
