Multiple issues , need assistance

Sovol SV08
,
1

Hello everyone.
I am experiencing 3 separate issues with my Sovol SV08 which is 1 week old.
Please see attached pictures.

  1. It seems to me that heating bed is not level. The back left corner seems to be too high, and front left too low. I have played with 6 screws under the bed to get the level adjusted - no result.
  2. Plastic is not bonding together nicely in some certain areas of the bed. In the centre it’s almost perfect, everywhere else - not so great.
  3. Poor adhesion to the bed especially on the front of the bed.
    P.S. Z Offset leveling and Quad Gantry Leveling was done prior to start, as well as the bed surface has been cleaned with isopropyl alcohol 70% concentration.
    Please let me know how these issues can be addressed and fixes.
    Thank you

I took an SOS pad (steel wool with pumice and cleaner embedded) to my plate which improved adhesion with ABS to the point that I’m having to forcibly remove the prints.
There is a post detailing adding shims to the retaining screws for the bed, but I can’t recall
if it was here on the forum or on reddit.
