Hi all,
I just recently have got myself a K8400 and I’m really happy with it, except for 1 thing. When i print without a raft all the prints come loose from the platform. mostly around layer 8 or 10, and around layer 12 to 14 the nozzle starts dragging the print around or starts damaging the part of the printout that came loose. When i print with a raft, i get near perfect to perfect prints. I wonder what im doing wrong. Some help will be great.

it sounds like the distance between your nozzle and print bed is too large
it should be around 0,2mm with PLA (good idea to get a set of feeler gauges)
sometimes the build platform is not completely level so check the distance at multiple locations, not just the 3 shown in the manual
You didn’t mention if you’re printing with PLA or ABS.
Also check if there’s no oil on your Buildtak. Clean it with a solvent (alcohol).
If your object only has thin walls in contact with the bed, add a brim.
Lower the temperatures (195-200 max for PLA and 220 max for ABS) and the flow (75% max). Too much filament extruded ends up with curling corners and your piece being knocked off the bed.
Thanks, will do, an b.t.w. it was PLA
