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

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

Saturn 4 "Resin exceeded maximum limit"
Since this post, and seeing it from others, I've worked out that the elegoo in vat fan heater seems to be triggering the sensor. If the heater is on when the bed passes it I get the error. I've reached out to elegoo to see if there's updated firmware to stop this. Otherwise I have to pre heat, turn

Why did my build turn out like this
What resin are you using? My settings on my Saturn 3 ultras are as follows. Bottom exposure 30s Normal exposure 1.4 to 1.8s depending on the resin Normal lift height 1mm + 2mm (that's what cuts your print time down to nothing not lift speed, you can go from 120mm to 240mm normal lift speed and it on

Suggestions for next printer?
Worse UV uniformity, has the same design as Phrozens, which have a mirror in the path and so only the central area of the LCD has good UV power and it drops off like a cliff afterwards. Elegoo went back to the design of the Saturn 2/3 for the Saturn 4s (COB + fresnel only). Also can get bad castings

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
