I suspect it is a Z axis bearing problem. At that exact height, the bed is dropping down a bit more than it should, giving a weaker layer. In ABS, that layer will fail due to warping.
I had similar problems some time ago, that prompted me to switch to PLA. Cured it by removing all lubrication from the Z axis pillars and getting new roller bearings under warranty.
Thanks for the insight, I moved the bed a tad bit tighter to the nozzle when leveling and it looks like that solved the problem as I was able to successfully finish the print. I am however going to keep an eye out and keep this in mind if it happens again. Thank you so much for your help.
PS: there was a ton of the Greese on the lead screw,so I wiped down all the excess maybe that could have helped?
