What is the ambient temperature? Do you have newest Z-SUITE and firmware installed? Also, do you possibly have some other Zortrax resin to run a test print?
You may also try increasing additional support exposure time and bottom layers exposure time.
If the problem persists - please send us the .zcodex and .stl file via support form.
Thank you for a quick response.
I had the latest Z-SUITE, but updated firmware to latest one. Then I calibrated both platform, and exposure time again, and changed resin to am unopened bottle.
