Resin printing "arms race" over?

Same as before. Expect 12 months between cycles. This year was odd, printers got released on a shorter cycle. The Saturn 4 Ultra 16K was probably supposed to be the Saturn 5, but Elegoo released it early (only 7-8 months after the Saturn 4/4 Ultra). Probably because Uniformation was releasing the 16

Elegoo Saturn 4 Ultra 16k - Water Washable

I'll just assume it bots or something, but for whatever reason, this thread is just filled with wrong answers. Well, technically the Wait time before print suggestion is correct, but is still useless because it fails to provide any guidelines for settings or why it works. Rest / Wait time is why you

Saturn 4 Ultra 16K, over a year of troubleshooting and I still can't fix it.

The S4U springloaded plate means that wait times are even more mandatory than regular printers. The light turns on way before the resin has settled and the springs have found home. This means you get a layer thicker than supposed especially at 20um, your bottom layers are probably closer to 0.5 or e

Looking to replace my current printers. Need input from professionals

Yeah Anycubic long term support is ass. I own an M3 Premium and they ended support for them almost 2 years ago, yet I can still order parts (other than LCDs) for my Saturn 2s from Elegoo... which are the same age as the M3 Premium. Heygears is supposed to open up some of their settings later this ye

My friend's saturn 4 ultra has it's screws going up and down on the build plate, is this normal??

Ignore Hupdeska, they are constantly posting BS without knowing what is going on. Normal for early / base layers on the S4U to pop the spring floated screws, but it is not the best for the LCD lifespan. It's the build plate being forced up by the tilt release return, and usually some base layers whi

Is this the quality I should expect from the Saturn 4 Ultra 16k?

This. The default settings on my Saturn 4 Ultra 16k where WAY high, so everything was "chonky" and parts wouldn't fit together. Downloaded the cones of calibration, did a multi-exposure test, and iirc ended up around 1.75 seconds, with the default being (again iirc) 2.3 seconds. At default, getting

What to do next.

Anycubic’s QC with the M7 has been pretty horrible. I’ve seen a lot of concave build plates. Add to that the auto-leveling system has issues with adhesion, and since you can’t use UVTools to add long wait times for early layers, there’s no real fix if you’re having problems. I’ve helped too many peo

Foreign object detection, but there is no foreign object…..

I ended up returning it because I couldn't figure out how to get it to work. I purchased a gk3 instead. Things that I notice between the two. The elegoo software is pretty awesome. The GK3 developed a divot on the screen, I believe from poor cleaning on my part. It made me understand why the pressur
