Anycubic Photon Printer Owners 造訪社團 » 用戶發文

Hi, I guess my last post died, so I'd like to ask further questions separately.

I've got troubles with terrible curing times on my old version of Photon (blue windows) - on monocure rapid clear its like 40-50seconds. I got a suggestion that LED array is broken, so I checked it out.

I've taken a photo through the welding filter - all leds seems to emit light, an the array gets hot pretty quickly. The other two photos are LCD tests without and with the array attached.

Does it mean that the LED array is ok, and I should search for the failure elsewhere? Or the light emission all alone doesn't mean that it isn't broken?

Hello!
I've got three problems with my photon printer (I must add, it's an older version, with blue glasses). Slicer: chiTu box:
Dramatically long exposure times needed (I've tried 0,05mm layers) - for Monocure Rapid clear the results from the exposure tests were 50-60s, in comparison to 11-12s that is recommended by its users. That causes that most prints require over a day to print out, which is ridiculous ;/ Z-wobble (?) and squeezing the bottom parts of prints - the cube is like "cut" in the bottom, also when I add 5mm offset from buildplate for supports - its like 2-3mm high. Also prints has small "scars" on them in z-axis. Bad surfaces over the supports - especially with flat, big surfaces, it seems like the resin has trapped there on the top of the print, and hardened there during the whole printing process. Obviously it looks better for prints tilted by 45 degrees, but not perfectly at all.
The things I've already done: plastic cover for all the windows in photon plenty of re-levelling bed, trying to print with tight fit of piece of paper, and quite a loose fit checking it with dry runs - piece of paper moved easier after first few layers re-tightened z-rod cleaned the brass nut on the z-rod and changed the grease on the z-rod changed lifting distance to 40 mm and 60mm for the bottom - it hasn't seem to make any difference
I attach some photos. Do you know probable solutions of any troubles listed? :( 翻譯年糕
