So WTH does this mean?

Is this:




The reason for this:



And does this mean my LCD is effed up?

If it is, it’s easily replaced. Mine got damaged in a resin spill. I upgraded to one that is less expensive than the AnyCubic replacement and more efficient at UV output:

6.08 Inches Mono LCD Screen for... https://www.amazon.com/dp/B09921BSCL?ref=ppx_pop_mob_ap_share

They have various sizes for specific printer models, including all of the AnyCubic models. I also added a screen cover to prevent resin leaks and spills from damaging the curing screen:

Same situation, dimensions-specific based on printer model.

You decrease the curing rate with the new LCD screen above but lose efficiency with the protective film applied. My net result was a one-second improvement on my slice interval for both the standard and abs-type resins.

This is out of the blue, prior print was perfect, no resin leak, no tumbles, etc. FEP os clean. Could it be that the screen was pressed on with the bad print above when the build plate came down?

It that the light test?  If so it should be a rectangle. (is on my machine)

It looks like one of your layers.

No.

I ran the slice file for the print that failed above. That was the first layer. I wanted to see why it looked like the print had a huge raft, but the file does not have a raft at as you can see by the slice. The billed looks like it would expose unintended resin, as the print shows.

Ugh.

Might try to turn off the machine and disconnect and reconnect the lcd to the board.

And check the slices in Chitubox. Sometimes it will swap slices.

To go further. Remember all those problems I was having with stray triangles and I was going into the pixel editor to clean up every file after slicing? Well I updated ChiTuBox and all of that went away. So it was the slicer the whole time.

Every once in a while it would swap 2 layers. Like layer 3 with layer 369. So 3 is in the raft. After doing 369 instead the rest of the print would no longer stick. It was all the slicer.
