I finally got my octoprint working with an external power supply. I've been having issues with the first couple layers in certain spots of my bed so I installed and ran the bed visualizer and this is what I got. No wonder I was having issues.
I've read someplace that the bed autolevel really only works for +/- 1mm. Seeing this kind of issue, are my only options a hammer to physically get it flatter or are there better bed levelers options out there?
I just went through your UBL post. I'll give that a try and update this post with the results.
You can try more points. Right now it's a 5x4 grid. You could always try a 7x7 for a really detailed 49 point bed. You could also try switching from bilinear leveling to UBL (10x10 grid)
