ridges in prints (solved) First off I'd like share that Slic3r is great and has given me better quality prints with one minute making settings then days of tuning with the previous "one" I've been using. However, I've been noticing ridges along the z axis in my slic3r prints and was curious if this is an isolated event or not. I'm attaching a picture showing the ridges. The piece on the right was using slic3r and the piece on the left I did with sfact. Both used the same stl. It's like my flow rate is slowly increasing and decreasing across 10 layers or so. I believe it's a slic3r issue as I've only observed it on my slic3r prints. I'm using 0.5.7 https://reprap.org/forum/read.php?263,111902,111902#msg-111902 Tue, 17 Mar 2026 12:18:27 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?263,111902,112551#msg-112551 Re: ridges in prints https://reprap.org/forum/read.php?263,111902,112551#msg-112551 I'll see what I can do true up my lead crews.

I get a similar problem to this - could it be slightly fluctuating temperature? I also get a similar (but less regular) effect if I manually adjust my nozzle temperature when the machine is running.]]> Lucastar Slic3r Thu, 05 Jan 2012 17:04:22 -0500 https://reprap.org/forum/read.php?263,111902,112405#msg-112405 Re: ridges in prints https://reprap.org/forum/read.php?263,111902,112405#msg-112405
As to why you don't see this with sfact, it could be a different flow or speed irons out the flaws.

Nice prints though. :)]]> Nudel Slic3r Thu, 05 Jan 2012 12:43:36 -0500 https://reprap.org/forum/read.php?263,111902,111902#msg-111902 ridges in prints (solved) https://reprap.org/forum/read.php?263,111902,111902#msg-111902
