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

WiFi with 3rd party slicers

On my Elegoo printer, what I do is I use third party tools (including UVTools) and then I just upload using Chitumanager. Chitumanager is installed as part of Chitubox slicer (if I remember correctly?), but after that it's basically an independent piece of software that can take a file from disk and

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

Separation and Partial Failures on Elegoo Saturn 4 Ultra

Exposure time too high with too few transition layers, and not enough Rest Time After Retract for the bottom layers. Though to be fair, Chitubox does not let you set different Rest times for the base layers, and none of the other slicers let you set them for a different number of layers than the bur

WiFi with 3rd party slicers

I can send files directly from Lychee, Chitu box and Satellite to my elegoo Saturn 4U16K as well as Mars 5U. I can also access both printers information through home assistant pretty much completely including the video feed, all across VLANs and wirelessly. I haven't tried sending anything through t

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
