Bed Adhesion Issue
Posted: Tue Jul 24, 2018 1:20 pm
Okay, so I have a RostockMAX v2 which has printed fine in the past. I recently moved the printer to across town to a new location. I also took the opportunity to upgrade it with a new HE280 hotend. Lastly, while I have been using glue sticks for bed coating preparation, I read in one of the forums that hairspray worked well so I started trying it instead.
The issue is that I'm having mixed results that perhaps have to do with poor bed adhesion. I've tried printing carbon fiber petg and abs. Carbon fiber noz @ 250C and bed @ 60C. ABS noz @ 228C and bed @ 80C. Fans are off.
I checked the Z axis and found it needed recalibration. Re-calibrated the bed as well. Didn't solve the problem.
I have also tried less/more hairspray and increased the brim size. I seem to get good adhesion initially but after the part builds about 0.125" high I start seeing lifting of the part from the bed as the part begins to warp up at one edge or another. Thoughts?
Thanks
John
