Too many Mis prints

[EddyF]

I think I always had too many mis-prints. but now I'm getting one of ten. And now I'm decided to figure out why I get so many. And never been successful at printing 80 x 45
The project has 800 hours on the bulb, but Infocus replace the machine a year ago.
I lubricated the Z screw and increased exposure to 3 seconds, Buffer time to 2, level the build platform cleaned the mirror.
The last picture is the Solus test rings. I stopped it after I saw I had problem, the other pictures are two different beads

Hi Eddie, email me and I'll have you run a few tests to see what the problem could be. Have you tried printing using a different resin?

Did you calibrate the grid to 80x45. Focus the projector, grid. Put the right arrangement of close up lenses? Could be a film problem. How old is the film? Put in at correct tension? So many things that can cause it.

For what you are printing in those pic's, I don't see why you need the larger print area.

Yes, new film, i have played with tension. These are all at 48x27. I having a lot of mis print now. But is always has been about 50%.
When I first got the solus it printed fine. then about a year in, I had problems printing. I got Infocus to replace the project for another one. But I'm not sure how to test the project or bulb

This doesn't look like a film issue. Seems like not enough light is coming from the projector. Try increasing the exposure time by 1 second. See if that does anything.

What are you looking at that makes you think it could be lack of light? uniformity of failure?

The tips of the supports.

Just so you know when I added one second and it would print.
I changed to a new bulb tried 2.6 seconds at 20 and had some pieces fail. So I'm going back to adding I second on the prints again and see if they all will again.

Like I said, your new bulb that you purchased could be weaker than normal. Not sure why.
