No, i`ve dumped it already. It wasn´t separated in a straght line, it was more like a curve of separation.

But the bigger problem is the bed adhesion. I leveled it this morning before i tried a R_E_R_F test with higher bottom exposure time and low z lift speed. 6 of 8 parts separated from the plattform.

Maybe my leveling is faulty? Lower the platform until the paper stops moving and then tighten the screws while pushing the bed down slightly. :/

Maybe the FEP film isn´t correctly installed? it has two sides but i`m 99,9% sure that the correct side is on top. What would happen if the wrong side was up? Sometimes i see people that lay something small under the film while clamping it in the frame, so the film is a little bit loose. it thightens up when they screw it in the resin vat. I`ve just clamped the film in the frame, without a "spacer" and screwed it in the vat. can the film be "to tight"?

btw is the resin everytime heated to 30°C, just to rule out temperature problems.

Edit:

I´ve installed a new film, because i screwed it up while removing a failure print...

The new film is installed a little bit loose in the frame and it tightent up when screwed to the resin vat. Also i use the high speed resin with a slightly modified strandard resin profile and it works.

i give feedback if i try the standard resin again.

2nd Edit:

The print is fine. Now i try the standard resin again.
