Diagnose this PETG problem
Posted: Tue May 16, 2017 4:48 am
I've read other posts on the forum about printing PETG and have adopted most of those print settings, but I'm still experiencing some issues. The outside of this piece looks pretty nice, but the inside surface, where all of the layer changes occur looks pretty bad (see attached picture). It has blobs, strings, and burnt bits all over. Here are some pertinent print settings:
Hatchbox PETG
240 extrusion temp
50 bed temp
0.88 extrusion multiplier (I use 0.89 for PLA)
2 mm retraction
5 mm coast
45 mm/s print speed
Any idea what could be causing what is in the picture?
