Are you sure you only turned the middle screw a half turn to your left? The value has almost doubled in the wrong direction. Turning to the left or clockwise when viewed over head raises the bed which lowers the value. Turning a screw to your right or counter clockwise when viewed over head lowers the bed and increases the value. The thing to remember is the bed pivots on screw B so moving screw A will have a slight opposite affect on screw C and viceversa. If A goes down C will rise slightly, if A goes up then C will lower slightly so you can't adjust one screw only. If you Adjust A, then you will most likely need to move screw C in the opposite direction by about half the turns. Thats why you must make sure you do the exact number of turns the image is showing and in the correct direction that the arrow is pointing.

I cant do screen shots but based on your current values you need to turn back right .29 turns counter clockwise or away from you. Front middle .92 turns or 1 full turn to the your right or counter clockwise. Then back left needs 2.12 or 2 full turns clockwise or away from you. When I refer to a direction I refer to the open edge of the screw that your finger touches.

No worries, we'll get you there.
Try this ....

Sorry to bother you guys again, but it says "+185, +205, +215" could you help me? (It's the closest it has ever been!)

Thanks,
Andrew

Back right .33 turns clockwise, Towards you. Front middle .08 turns Counter clockwise to your right. Left back .17 turns clockwise or away from you. These are very small turns, in fact I would not really worry that much about the front and left back. Just turn the right back as specified and rerun. Should pass or be so close a slight nudge will put you there.

Calibrating...

Yep that would be a birdbath for humming birds.... Also just so you know the white filament they supply with each machine is rather bad quality wise. I would order another like black or a dark color as they seem to print better. The lines blend better and don't look globby like the one on this does.

Well, the paper method didn't work for me. My three numbers after doing the paper method are "+425, +275, +185". Could you tell me how many turns I would need to do for A, B, and C?

Thanks,

That is where you made your mistake. If you read my method correctly it told you specifically never to run auto cal again after you get a pass.

Run auto cal once till you get a pass. It does not matter what the values are. It is simply to store a value that the printer sees as a pass.  Once you get a pass then use the paper method and never run auto cal again. The issue with auto cal is that it does not know your print height and that is critical in determining your correct bed height. The height should be half of your print height. A sheet of paper puts you around .15mm which is good for most print heights unless you go below .2 which is for the most part useless and you are printing artistic objects.

Also the numbers are reversed from the screws so that adds to it's complexity. The number are from left to right A, B, C, the screws are actually  A= Back right, B=Front Center, and C=Back Left.

Sorry, I didn't understand. I will do it again. What is a pass? (PS: I just got started in the 3D printing area)
