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).

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

Looking at a Saturn 4 Ultra 16K; what wash and cure to use?
Hello, fellow hater of new machines from Elegoo. Elegoo overall not bad. Just those ''new gen'' with bunch of useless features and bugged tech - bad. Saturn 3 \ ultra. Mars 4 ultra. Hell, even old Mars 3 and Saturn 2 = great machines.
