Bad printings

Hi guys.
I’m starting to have problems with my printings, as you can see in the photo, there are two rims that doesn’t print well, but at the ones at the front prints perfect.
I clean the mirror in the form, also change resin tank and use formlabs white resin.
Any ideas?

Hey there @SFernandez!

Thanks very much for taking the time to post! Sorry to hear your recent prints haven’t been coming out so well.

As you correctly surmised, these errors do very much look optical in nature. That being the case, you did exactly the right thing by switching out the tank and taking a swing at cleaning the large mirror.

Because you already tried those things and didn’t see any improvement there’s a couple things that could be going on. The first option is that the cleaning of the large mirror just didn’t quite do the trick. This isn’t that uncommon, as getting a spotless mirror out of that process can be a little tough!

The second option is that the fault lies further back along the optical path, whether that’s the small mirrors or the printer’s galvo mirrors.

In either of these cases, the best thing to do would be to get in touch with our support team at the link below and we’d be happy to give you a hand, whether that means helping with another cleaning, or potentially replacing those mirrors for you. Hopefully we can get you back to printing as efficiently as possible!

Printer is not yet in warranty.
I had talk with support people and they send me a pdf with how-to so gonna clean the galvo mirrors.
Thanks guys
