In the last four prints, I have had the piece lift off the plate twice. Both near the end of the prints. The prints are tall relative to their area on the plate. 40mm OD, 165mm high for this last one. I'm trying to reduce this print failure rate to a very low level. The part is in PETG. I'm using a Prusa i3 Mark3S+ printer with PrusaSlicer 2.6.1. Print file is pretty large 37MB. I did make a project file, it is 10MB. I can attach them if it is ok.
Things I have tried:
1. Used satin steel sheet, which I originally had over adhesion issues.
2. Cleaned sheet with 99% isopropyl alcohol prior to use
3. Sprayed AquaNet hair spray on a cold sheet and wipe off most of the liquid with Kim Wipes
4. Added a wide brim to the part
5. Print in draft mode, with variable layer height for the upper section. This is primarily to reduce print time in the object, and get narrower layers for the top of the part
6. Fan speed min 30% - 50%. Disable fan for first 3 layers. "Full fan" at layer 5.
After this print I will look into reexamining the bed leveling. It's been a while. I haven't moved the printer at all since the last time, not sure why things would change, but, stuff happens.
Anything else that I should change or do? Losing an 8 hour print after 7.5 hours is no fun, hobby or not. For one thing, it makes you second guess your design, and then you fiddle around making improvements. These are exploratory prints to try to see what works better.
