Another blob problem! Arrrggg.

[wirlybird]

I just printed this 20mm cube. It is pretty good but it has a consistent blobbing on the corners, saw-tooth look. It is the same on all four sides and appears to be every few layers.
Mostly default settings for my printer (QIDI).
Material is PLA.
temp 190.

This is most likely the same issue as your other thread. Sort that one....and this will probably be sorted as well!

Hi wirlybird,

Apologies for resurrecting an old thread, can I ask how you resolved this issue? I'm having the same problem.

Thanks.

It really isn't resolved just a band-aid. I set the start points to the specific setting and it helps - sometimes! Sometimes add negative restart to cut down on the blobs at the start point but that has a trade off. It can affect small/fine detail parts of a print.

I may be wrong.....but this issue looks exactly like the issue in the photo in this thread: viewtopic.php?f=9&t=6795

Your blobs look like someone else's zigzags!

You got it! I saw a notice for a reply to this old post of mine and then saw his post!

This issue is a real annoyance with S3D but I have tried to live with it. Some issues like this seem at least on the surface (pun optional) to be fixable in the software but don't appear to get addressed.
