Hi @3DPrintandStuff welcome to the wonderful world of printing with ABS! This is (mostly) called “delamination” and is something that ABS is prone to, even with a heated enclosure. It’s a complete pain, and one of the reasons I try to print as little as possible in ABS these days. The two primary culprits for delamination are too large a layer height and too low a print temperature. From looking at your photo, I think the layer height is probably OK, but 215C is low for ABS. I print at 230C for ABS with my FF Pro, so I’d give that a try.
I’d also suggest trying to make the enclosure itself as warm as possible before starting a print. If I’ve been forced into printing with ABS, I usually run the bed up to temperature then leave it there for at least half an hour (with the door closed, cover on), so that not only is the bed thoroughly heated through but also that the enclosure and the whole printer body has warmed up. I’ve found this especially important now it’s Winter here in the UK as my office is often down into single figures when I first start work.
If you take a look at the photo attached, it’s much better print, only thing changed was the filament which was from Form Futura rather than the no brand reel that came with the printer.
IMHO shows that good filament gives good prints.
