The printer is 2 weeks old, has made 4 runs a 10h with Blackv4
Since 2 print the surface has a partial orange skin.
The surface dries badly after cleaning with IPA. It feels like a porous surface.
After curing, I can smooth the surface by grinding. But that’s not the surface I’m waiting for.
I filtered the resin and cleaned the resin tank LT,
The bottom plate and the tank have no visible traces.
The glass which separates the laser from the resin tank has traces on the bottom which I can not explain.!
the tracks under the glass
still fresh in the printer / the red area is affected
after washing with IPA and dry / the red area is affected
i worked with the support for a few days.
thanks again for the friendly support.
the solution was to clean the optical disc from the bottom.
this had an oily surface.
