Warping after upgrade 2+

[fgeer 0]

I have a problem with my UM2+. After the upgrade 2+ I can print only at the middle of the bed. When I want to print multiple models for example 4x in the corners my prints are all warped. I leveled the bed several times and this is perfect. I did try with 60, 50 or 40° bed temperature but always warping, only in the middle perfect printing. Who is familiar with this problem? I followed the upgrade 2+video thoroughly

The leveling procedure is not so good.  Try it my way as shown in this video.  The link below should jump into the UM2 leveling procedure at 4:49 but there is other great advice in the video.  I tried to keep it short but there is a lot of details to getting parts to stick every time perfectly.

ARRGG - this stupid forum won't honor the full link. So just skip to 4:49 in the video!
