I’ve been having problems with my current print. I am using ABS on a TAZ 5. Filament Temp is 235 and bed temp is 100. After about 7 perfect layers the next layer will not adhere. As you can see from the picture it starts looking like a cheese grader. No fan running. I have never seen this before.
I have rotated the print 90 deg. and no change. Any help would be MUCH appreciated.
