Probably needed the chamber hotter or more stabilized temp. I usually preheat the bed until the chamber hits bout 40c then I start he print. NO FAN!!
I run 100 bed and 230 nozzle. The warping and cracking is usually cooling to quick.

Re-printed it in Raptor PLA and it's just perfect. One of these days I'm just gonna stop beating my head against that ABS wall.
