Running into a small issue. Printer has been acting up for a few weeks, thought I resolved it, then it did it again. Decided it was time to update the firmware. Downloaded the latest from Anycubic (4.2.19) and flashed it. Once I did though, the screen had lines running through it for the UV Test. Reflashed back to 4.2.3 and it's fine.

Everything I read online say's there should be 3 files: An LCD file, a BIN file and TXT file. The 4.2.19 only has the LCD and BIN; Am I missing something?

Thanks in advance, apologies if I'm being dumb!

Anyone here try swapping their Photon's LED chip for an LED array? I know it's not a drop in replacement (you'd need a different power supply and a driver board), but the Photon's lack of uniformity and curing power is one of its biggest weaknesses, and it seems that would be an effective fix, as the possible expense of reduced LCD lifespan from heating (although I was also thinking of modding in a cooling blower fan between the array and the screen when I made the adapter).

Success! New LCD screen, back in action!

So three weeks in with this printer and I have a print which has a "hole" in it. I proceed to test calibration print which is mostly a flat plate and it has the "hole". I then empty my vat, place a piece of paper under it and try to print the test again and get the second photo you see below.

There was a time before I recently replaced my FEP that a small bit of resin leaked through a pinhole. But it wasn't much. and it hardened on top of the LCD. I used a razor blade gently and it came off as a wafer thin sheet of resin. Is it safe to say some got under the LCD?

Is there anything other than replace the LCD to do at this point? Or has anybody had success cleaning the inside of an LCD of hardened resin?

Finally, 2 weeks later. New LCD arrived. Would anyone be interested in a live video install? Let me know, putting in after dinner in a few hours

So, typically I'm the one offering solutions, but I've been having a helluva time with my prints lately. I've noticed that the print bed angles up when it is at the bottom (like when I start a print, and it goes to full travel down, it hits the bottom and looks like it pushes the front of the bed up). Anyone have this problem? Nothing else is wrong, no broken LCD, the FEP is likely due for a replacement soon, but nothing major(any tips on the proper app for tuning the FEP?) Since a few prints ago, I've had at least one failure per print (something falling off supports, weird lines at the bottom of the figure, all sorts of stuff). I'm hesitant to take the machine apart, but it feels like I will need to to get to the bottom of this. I used to be a heavy aircraft mechanic, and I just know that if I do take it apart, I'll end up breaking something important getting it all together again.

I'm having an issue where the entire bed of the vat cures. Does this test look normal to you? The shape of the layer is appropriate, but I can't tell if the glow on the entire LCD is just light refracting into the rest of the screen or if it is actually lighting up and curing everything. The layer was around a mm thick when I stopped to check. It also burned my finger a bit fresh out of the vat, and I don't know if that's normal or if the LCD is lighting too hot causing this issue.

I had issues with the LCD of a Photon S I ordered from Amazon a week ago, so I sent it back for a new one while I still could. This is the first print on the new one. Maybe I just leveled it wrong? I have no idea if a bad leveling could cause the entire vat to start to cure.

Just got a replacement LCD from Anycubic but I can't seem to get the ribbon cable to go past this section here where it looks like the cable has been clipped into an extender cable... Any tips on how to get this section inbetween the glass and printer body? Really anxious about tearing the cables as I know how fragile ribbon cables are!

Anycubic support doing them proud. Can't find my original post to update it but long story short I had a mark on the plate under the LCD and contacted them about it. Since they don't sell them they kindly sent me one along with 'some' (a whole roll !!) of tape to secure it. just over 10 days from Shenzen. Thanks Anycubic, I fully expected to pay for a new one but you offered it free before I even asked so very happy :)
