Answered ABS not sticking to... self?

I just made my first print with ABS and was impressed with how perfect everything was going and how the calibration print look so perfect.

Then, I removed the print. Everything more or less fell apart, like the layers didn't stick to each other. Bed adhesion was great, but it was like I just made layers of toothpicks that fell apart when removed.

Unfortunately, I had already ended up with 5 spools of ABS before knowing that PLA was the way to go, so I'd hate to waste the stuff.

I have no idea if this is a temperature issue, extrusion, or anything. I printed at 235 on a 105 bed (On PEI).

Suggestions on what might be happening?

 

I tried a full calibration cube (same settings, except .3 layer instead of .2) and that printed almost perfectly - I was expecting shrinkage, but it was actually a little larger than the 20mm.

I did have some warping/waves on the edges. I'm not sure if any settings should change between PLA and ABS aside from temps, I left everything else the same.

 

So, 245 on the single layer testing came out perfect. I'm still a little unsure which temperature to go with for full prints though, since the full cube at 235 came out so nicely.

Full cube at .2 layer and 245 had a good bit more warping on the corners. Bonding was great though
