Hi folks, I recently upgraded my Taz 5 to an Aerostruder, and things have been OK. However, I recently tried printing a model with a very large “block” of plastic (https://www.thingiverse.com/thing:2585644).
This piece takes about 18 hours to print. Mind you, my bed level and head to build plate offsets are quite dialed.
I have had 3 failures in a row. Most happen around the 50% mark, so ~9 hours in. Given how far along they are getting, I ruled out back pressure.
I’m using a fresh spool of Makergeeks standard grade PLA @ 210 deg. A little high, but I generally get good results.
Infill is @ 20% honeycomb with 3 perimeters (using S3D).
Any ideas? I;m thinking I’m getting heat creep.
