I have had this print fail a couple of times now. The arms reaching out from the centre uplift from the PEI build sheet causing the model to fail. I applied glu stick and both times it didn’t work. Any suggestions from anyone to fix the problem?
-
Make sure the PEI plate is clean and wipe it down with alcohol too.
-
Use a brim, a wide one, maybe a width of 20. You can add “mouse” ears at the ends of the arms for extra grip.
Large irregular shapes will have non- concentric cooling causing shrinkage so the time and filament used to hold it down is worth it.
Let us know if it helps.
I tried using a brim but the shape of the brim does not work. Also the brim does not go around the model only around some parts.
If the brim does not go around the whole outside I would suggest to check to see that model is actually sitting flat on the bed in the slicer. You may have to tweak the orientation.
Are you sure the slicer is set to brim and not just mouse ears?
I got it to print, finally. I turned off the side fan.
