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).

Mars 4 Vs Mars 5
I've got a Mars 4 Ultra on the way. It didn't seem like elegoo offered replacement feps on their website for them- the website calls them acf film and they're asking $10 per which is twice what the 'fep replacemnts' for thears 3/4/5/5 ultra go for... It gave me much confusion https://us.elegoo.com/c

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.

Looking for an Elegoo OEM 10.1" 4K Mono LCD or something comparable.
The FEP you can probably get some other generic resin printer film and use that, but getting a replacement screen doesn't really make much sense IMO. You might be able to reach out to elegoo support and see if they have any any left but usually screens are only available for around 3 years post laun
