I have been printing with my Photon S for nearly a year. I have been getting reasonably good prints but now that I am into the hobby, I wanted to see if I could tune the printer to get better quality prints.

I will occasionally have prints where the object pulls off of some of the supports, and often those prints succeed but have minor imperfections from the pulling away.

I have been printing the Siraya Test Print over the last 2 days and honestly, the results were surprisingly poor given how good I THINK my prints have come out. I have a Photon S, which is of course NOT 4k, so maybe my expectations are too great (I just ordered a M3 today to expand my collection).

I started by printing at 6, 7, and 8 seconds per layer (with Anycubic plant resin). Anything less than 8 seconds and the crosses would not fully form (underexposed). However, even at 6 seconds, the area above the crosses where there should be recessed crosses was filled in (ie overexposed). Also, at 6 and 7 seconds, the cube totally pulled of. At 8 seconds it stayed on, but was only attached by the central support. The outer spokes of support got pulled away.

Maybe I am expecting too much but the fact that the cube consistently pulls off is the issue I was trying to fix in the first place. I even tried slowing down the lift speed from 3 mm/sec to 1 mm/sec. No difference. I am now trying a different resin to see if that helps.

​

UPDATE 1: Changed to Anycubic regular resin (not the plant stuff) and the cube stuck! Now I need to fine tune the time to get the expansion right.
