So I’ve been trying to print a very simple rectangular box, and I keep having the same issue to varying degrees. One corner of the print lifts up during the print and/or a layer shift. The two prints in the picture were both printed in ASA, on the Engineering plate, with glue added for adhesion.
I’m still new to 3D printing and have kept most of the settings default. I have slowed down acceleration and some support settings. What specifics do you need to help me diagnose this issue?
Are you printing with a brim?
Yup. First thing I did.
If the AUX fan is on, I would switch it off. I also had very strong distortion with ABS because the part was blown on with plenty of air.
AUX fan is off, but PART fan is at 20% by default
Although I have no experience with ASA, this looks like classic warping.
Try to lower the print temperature (except 1st layer), slightly increase bed temperature (but not too much/too long or you may be seeing elephant foot), keep chamber temp high and reduce layer height to reduce the local thermal energy added per layer.
These will mainly reduce the thermal mismatch between layers which causes warping during layer cool down.
Soap and water(i know you said you used glue also). If asa doesnt stick, it will curl up into the nozzle and look exactly like this. Clean with soap and water, dry with paper towel(not dish towel with fabric softener on it) and then use bambu liquid glue if needed. Also set your brim to part gap to 0 instead of .1
Start the bed heat and then wait for the chamber to heat up before printing. Never open the door and wait for the bed to completely cool before opening the door at the end.
unfortunally Bambu ASA is warping a lot 
i still haven’t found a perfect solution for this issue (i’m not new into 3d printing and had other 3d printers before the p1s and printied lots of ABS without problems)
Even if the adhension is strong (i use 3dlac and smooth PEI), the warping lifts the magnetic buildplate. When i fixed the buildplate with clamps, it was i better.
ASA needs: high chamber temperature, high buildplate temperature, aux fan off, chamber fan low. try to pre-heat the chamber
That’s a good point.
Thank you guys. I’ll be trying these suggestions today starting with preheating the chamber and adjusting print temps.
The brim-object gap was already set to 0 
Is there recommended chamber temp before printing? I don’t recall ever hearing what it should be minimum.
I usually wait till it reads about 40c…

This helped, but on side still picked up. Adjusting temps again. Also realized ASA doesn’t want to stick that much to the Engineering plate for some reason. Switching to High Temp plate.
Dropped “other layers temp” to 250 as well, and layer height to 0.2mm. BTW I’m using a 0.6mm nozzle. IDK if that matters in this case.
While not necessarily fixing the issue of filament contraction, you can add parts to the model to make manual mouse ears. I tend to put down 0.4 high cylinders, sized about 35mm dia for parts that really like to curl. Just place them merely touching a few mm’s with the bulk floating off onto the plate.
I’ve noticed slicer’s brims don’t necessarily hold integrity as much and the manual mouse ears have held much better. They’re also easier to trim.
Note that this will still induce a lot of stress in the part. It’ll either try to lift the bed off the magnets or sometimes crack layer lines. Heat soaking as suggested helps alleviate this stress somewhat. So combine both approaches.
The answer was a combination of all your suggestions. Reduced Layer Height to 0.2mm, reduced Other Layer Temps to 250 (down from 270), preheated the chamber to 40C +, double checked Brim settings, AUX fan off, Chamber fan stuck at 10%.
Thank you everyone for your help:) @b3rnie @JonRaymond @StreetSports @EnoTheThracian @KanneKaffe
Thank you for this information!
