Top layer dragging in some spots
My prints seem to be largely ok, I'm using standard Fillamentum ABS with default "quality" settings from the slicer (240C, 100C/110C, .15mm layer). The print seems to be fine except for the top layer of some parts. I've included a picture where you can see it looks like the head was dragging instead of printing on top of the last layer. Other parts of the surface on the same last layer look smooth and as expected. I have an OctoPi connected but am printing from the SD card to bypass any of those possible issues right now. The layer separation on the back item was a change in bed heat I do believe so disregard that one.

Warping I think.
Could be overextruding, but not the whole part???, warping is not always very good visible.
If overextrusion, lower temp for nozzle will help or use the extrusion multiplier.
Make a print tower to now the good print temperature.

Looks like it came loose of the bed in that corner. Can you post a picture of the bottom too?
RE: Top layer dragging in some spots
Certainly, the prints always seem to be really well adhered. I use the supplied glue stick and first layer usually looks right so I don't think it's lifting up. 
RE: Top layer dragging in some spots
If it warps only a little then the nozzle will drag.
Put model on a very flat surface and check again.
