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).

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,

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 printers are everyone using?
I got the elegoo mars a while ago and used it a few times. Had failure rates of like 30%. Now heating and the fact that I was new to resin printing is probably the most reason. I then decided to take a punt and try the uniformation gk2. Bigger build area and heating makes so much of a difference. No

how reputable are elegoo printers?
I'm not convinced Elegoo or Creality are very good companies after owning a Mars 4 Ultra for two years that I have to re-level way too often, and struggling with the scan software that appears to have been written by a 4th grader. Their products aren't all bad but their customer service so far has b

Vale a pena comprar uma Mars 5 Ultra?
The Saturn 3 Ultra has worse UV uniformity, can have casting issues that prevent you from fully leveling, and comes with ACF release film as standard. ACF is known to cause fine vertical lines on smooth surfaces, and people complained so much Elegoo discontinued it after the Mars 4 Ultra and Saturn

Looking for a printer need suggestions.
id stay away from the saturn 4 ultra. flawed design for a large capacity printer as you will drip resin all over that thing when removing those large prints, probably hollowed, meaning resin will start POURING the moment you change orientation of that plate while removing it. Elegoo's "solution" is

Printhead PCB borked.
That’s precisely what I didn’t say or suggest. I don’t think Elegoo are horrible. I certainly don’t think the CC is trash, because it’s nots and I think their customer support experience is generally very good, and I have 6 Elegoo machines and every time I’ve had an issue they’ve been very helpful a
