I’ve been having issues with ABS cracking on large prints. I’ve built a cat guard that seems to be helping some but I’m still not getting the desired result. The picture attached shows the issue. I’m printing fairly slowly at 75% infill. Should I turn off my extruder fans and try again? This print has taken almost 2 days to reach this point (using the abs fine profile from the lulzbot site) with a 0.35 mm nozzle so I’d rather not start over without a solid guess on a fix. I was considering piercet’s open rail build as my next mod to see if that will help.
Also, would I be safe cranking up the speed/acceleration or should I stick with stock settings?
Thanks for any suggestions.
