Ok…I’ve tried to understand the solution, but I must be thick. I am able to adjust the three outside positions so that a sheet of paper just slides underneath the printer head. The center position (position 0) is to high though, and the paper won’t slip under it. As a result my ABS prints don’t adhere on the edges. My z axis setting at home position is 442. When reading through the forum, it looked like someone suggested to change the z axis setting to either 441 or 443…not sure if either of these solves the problem or the metal bed is warped? Any help would be greatly appreciated.

Hi, we also had issues with bed leveling and yes, the center of the bed is always higher than 3 other points. Our delta has a glass bed. We had a chance to speak with Delta Wasp manufacturer’s at the DIGICALshow in London and they recommended to us to raise the “First Layer Height” in the slicer. So we did to 150%. Now we print all items with the first layer higher than the rest.
in my personal experience was a problem of metal bed. i solved with an hummer…
hi, you can try to set the build plan when it’s hot, it will be exatly like when you are printing

Hello,
Delta Wasp 2040 at the beginning was designed with a thicker glass bed. There were some mechanical problems (broken bed with high temperature) so WASP decided to change with a metal bed. Your bed is not warped 
442 was the setting for the glass bed. With the metal one, you need to increase Z axis, try with 442.5 or 443, only experience can give you the solution and the best levelling.

Or glue stick. Pritt extra strong was OK for us.

All,
thank you for the responses…I will try adjusting the z-axis and using 150 for the first layer. We are using hairspray for adhesion which works great except on the edges…hopefully these adjustments solve the problem. Again, thank you for all of your responses.
Forget hairspray for ABS prints…
Flip the plate over. Mine was also high in the middle so I just took the screws out and flipped it. Now it is much more even
You can lay a straight edge over a heated plate and see that it is high in the middle. It is a result of just securing a metal plate by the edges then heating it. The expansion rate of the metal forces it to warp and that makes a high spot in the middle. WASP tried to compensate by creating those thin relief cuts on the bed frame to flex when the plate grows when heated but it doesn’t completely solve the issue.
They probably should have added more screws on the perimeter, allowed for the expansion when drilling the holes, then installed the plate heated to 100c to “pre stress” the plate.
I will suggest this to them.
Anyway, as I stated previously, if you flip over the plate it will be more flat, at least for a while.
Good luck!

Do you apply it to a cool bed, or when it’s already hot?
Hello,
I have the exact same problem. Fact is, WASP says it has no impact on prints and that you should choose an intermediate position (diference is just about 0,1mm or 0,2mm through the entire base)
The way I do it is to put a paper in the center position and then make the manual leveling routine. When the nozzle touches the paper, move the paper. Adjust the height so that you can move the paper with difficulty in the center (make it scratch). Then go to the remaining corners and let the paper slide without scratching.
Edit: do this with when the bed is already hot.
Thing is: ABS never sticks to the bed, either way. I recommend using Dimafix spray.
Regards!

I apply hairspray when plate is warming up…seems to work great, but then again, I haven’t tried it without hairspray yet…finally it is printing correctly Head at 245 and plate at 110. No issues now. Thanks for all of the suggestions.
