Unwanted patches of material on the pad at the first few layers


Hi there,

I have a quality problem with my form 2 printer & V4 Black resin. As you see below in the picture, there are unwanted patches between the bases of the two parts.

Can somebody give me an indication, how to solve this issue?

Thanks in advance


Clean the optics. This is usually the first sign on dirt on the glass window or mirrors.
