First Resin Printer: Saturn 4 Ultra 16K or Anycubic M7 Pro?

I have the Saturn 4 ultra 16k and I'm really happy with it so far.... So far. Lemme explain. Pros : heating vat (it's in my garage I'll be happy to have it in the winter) and tilting vat that allows a smoother printing  Cons : I'm not looking forward to the inevitable change of screen because the device is ill-designed on that matter and I will be forced to dismantle most of the machine just to do what's a basic maintenance. Include how to maintain your printer and the price of pieces into your reflections before deciding

Saturn 4 Ultra 16k vs Mars 5 Ultra vs Heygears RS

I have both S4U16k and Heygears RS Turbo. I would say the technology inside HS is much better: real auto build plate leveling, better sensors enable features like peeling force monitoring. Overall it is a much more reliable machine. S4U16K is cheaper but it is by no means simple machine, the tilt vat mechanism and spring loaded plate often cause more trouble that it worth, but it can absolutely print beautifully when you tune it right, it is just long and often frustrating learning experience.

Saturn 4 Ultra 16k LCD Screen Issues

I've been troubleshooting my Saturn 4 Ultra 16k going on a month or so now. I had a great time printing minis and had very few issues until I had a firmware update in April which caused my printer to not recognize the Z motor and the LCD screen. I worked with support to get a different firmware version which did resolve that initial issue, but after running a test print, I found that my LCD was no longer allowing any light through. After going around with support, they said that my LCD was out of warranty and that it should be replaced and appeared to be damaged. ( I had no visible damage on the screen, nor had I had any spills of resin into the printer) Well, I ordered a new screen and installed it this morning. I was sure to check that it functioned , and sure enough I got the Elegoo logo on the LCD both before and after reassembly (all green too, but I lost wifi for some reason). I set up a test print and left it for a bit, but when I checked back in, there was no cured resin on either the FEP or on the build plate. I checked the LCD again, and the new screen is no longer working but this time it shows an error in the LCD connection. I did some more poking around and then reconnected all the cables and reflashed the firmware using both the repair firmware and the version I found on another post from a couple months ago with similar issues, but with no lock. Anyone else seeing similar issues? I've already followed back up with support, but figured I would post in case someone else was going through something similar. TLDR: LCD went out after firmware update, replaced screen worked fine until test print, now it's all black and showing an error after checking and replugging.
