Saturn 4 Ultra 16K

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

I recently found this as well. It appears recent firmware to avoid the "lasagna bug" is either skipping layers or skipping the gray pixels when it can't load the image to the LCD fast enough. I have similar results with my own experiments in vertical smoothing / AA here: https://www.reddit.com/r/res

No, these are not graphics cards. There's a limit to their technological advancement. 16k print is close to injection moulding, any higher resolution is approaching gimmick status. Unless they revamp the tilt vat and improve fail detection, I can't see what tech improvements are to be made. I'm here

That will be a screen replacement. And, yeah it's getting too common with the S4U just past the 1 year mark. Here's my theory on the source of the problem - bad software configuration of the automatic leveling system and lack of a baked in Rest After Retract along with a couple methods to prevent th

Just going to copy-paste my comment from a couple weeks ago on the matter of S4U dead LCDs: For you next LCD, definitely look into use Rest After Retract (Chitubox) / Wait time before cure (UVTools name) via UVTools for the first 20 layers or so like the following settings: https://www.reddit.com/r/

I was going to ask if it was a Saturn 4 Ultra with the crazy thick raft you've got going on in the first picture. When you let it print rafts that far over thickness (what is that 1.7-2.1mm for a 1mm raft?). Your LCD has pressure spot failures, and it is likely because the build plate and overly thi

I've written up a longish examination of this issue -- your rest time is too low at the start of the print: https://www.reddit.com/r/ElegooSaturn/comments/1jwcwg2/fixing_saturn_4_ultra_elephant_foot_and/ The easiest improvement to LCD wear going forward is to substantially increase the Rest After Retract

TL;DR: The Saturn 3 Ultra is a bad value, the Saturn 4 Ultra is an ok value. Best value is the Saturn 3 non-Ultra. Phrozen is Elegoo and Anycubic quality at twice the price. And they generally have worse UV light uniformity. And their support sucks. As a former Phrozen owner, was glad to get rid of

I have had the same issue for about two years since I first started printing, I haven't gotten a good answer from anyone yet. I even got scales and weight everything, the weight of resin poured into the VAT, the weight of models and supports, weight of the IPA pre and post wash, I still have no expl

My main complaint with Lychee currently is that it completely shits the bed and crashes when I try to enable anti-aliasing when slicing for my saturn 4 ultra 16k. I'm led to believe it's because they haven't added .ctb support for my printer yet and .goo is a half baked format. Other complaint I hav
