I have been trying my best to get my bed leveled. I have watched a few methods to do so on youtube using fluid. After trying I went from 1.03 to a 0.54. The problems are the sides of my bed. The are very high and thus I loose a lot of build volume on my bed. Anyone have any suggestions . Here is my bed heat soaked at 50c
I had the opposite problem (my bed is curled upwards in the middle). I adjusted the four screws on the bed corners (under the build plate) to raise the bed a mm or two, then placed shims under the bed on the low sides, then lowered the screws again until the bed level was even all round - LOTS of fiddling and waiting for a bed level mesh each time. Still, I got the “cool” bed fairly level (within 0.25mm). However, when it heats up for ABS (my main filament on this printer) it bows again, along the Y axis, so I’m having to make sure I always do a bed level at temperature, before starting any prints.
I also applied some strips of 0.2mm Kapton tape to the bed magnet surface. That and Dangerous’s manual bed levelling trick got mine to about 0.3mm - much better than the original 1.5mm.
what did you use as shims ?
Checkout my post about this. I managed to dial my bed to .056mm of deviation on my first K2. Just finished making a tutorial using the second unit as an example (got it to .0780), with a bed that looked like it came from a Pringles convention.
For dialing in your leveling screws, checkout this video exclusive to K2 Plus. Before shimming, get it as level as possible using the method @Dangerous noted. The creator included some macros along with the video tutorial.
I followed this video to get to where I am at the start of this post.

To answer Gladius’ question, I used two M6x12mm countersink screws. The heads downwards to give a stable base on the metal frame of the bed. I filed one down a bit 'till the bed was level both sides. I positioned one each side of the bed, between the frame and the aluminium bed piece. I needed to position the left one very carefully so as to avoid putting pressure on any of the heating elements under the bed piece. These acted as anchor points in the centre of the bed edges, between the two spring-loaded screws on each side. Then I adjusted the screws until the two sides of the bed were level across their length, and with eachother.

Wow that is hard core. I"ve tried some high heat rubber things from my ender 3 bed.
Looking at it my first layers are really bad it seems to rip itself up even with high offsets. Whats a good site to host a video clip for here ?
