Comment on I'm doing something wrong; can't print this PETG
CrazyLikeGollum@lemmy.world 1 day agoHow can you tell it’s under extruded?
@PostnataleAbtreibung@lemmy.world said the same thing in an earlier comment.
If there’s some clear sign of under extrusion it might be useful for my reference doc I use when trying to troubleshoot failed prints.

IMO this is the same as any other hobby. Print enough and you’re likely to run into under extrusion at some point. Similarly, I can tell if doughs and batters needs more liquid or more flower by look and touch thanks to making a ton of pizza crusts and pancakes.
The first photo in the album looks like ‘classic’ under extrusion. The layer lines are largely intact, but way less material that is necessary for a solid print is present. The print has better and worse areas, which usually indicates a clog. Combine this with the fact that PETG will clog if you use too much retraction and a user that’s new to PETG and retraction seems like a good place to start troubleshooting.
As for helping your guide, simplify3d hasn’t been a ‘cool’ slicer in quite some time but they have a decent print quality guide that names a bunch of failure modes. Ellis’ print tuning guide is the best one I’ve come across.
