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

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/

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

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

All printers need more Rest After Retract (Chitubox) / Wait Before Print (Lychee) / Wait time before cure (UVTools) for the base layers. Your adhesion failure here is because your raft is printed with over thick layers. Almost looks like the raft was failing to adhere from the start or isn't actuall

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

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

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

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

If the Saturn 3 (non-Ultra) is available to you, it's the best bang for your buck and last of the non auto-leveling printers worth buying. Usually less than $270. Heygears is running a sale on the Reflex RS for $499, which is the lowest that printer has ever been. It's probably the only auto-levelin
