failed print on many items

[jaemescoll]

i need help please.
im having trouble with prints. as you can see the print starts well but as it gets closer to the head of the ring or the top it fails. i have even changed the film new resin but still it fails.

[jaemescoll]

it seems to be peeling.

[jaemescoll]

this is where it lifts.

How old is your bulb? How old is your printer? Did you shake the resin bottle really well before pouring?

[jaemescoll]

the printer is only 10mts old. and have printed only mbaybe 150 rings.
i did give the bottle a good shake.
i have taken the exposure time from 2.3 to 2.6 sec
lift speed to 80.

Have you checked your video/graphics card settings as per the user manual? Windows updates often will reset the video card to the default settings.

i will look in about 2 hrs and get back to you

so i changed the film again and i had a near prefict print no fails just a little fluff. looks like i may have had a dodge film.

I think your film was too tight. It now looks like the exposure is too high as you are getting excess/over curing in some of the layers. Try a re-print at 2.3-2.4 sec exposure.
