Hey guys, I just wanted to see if anyone had any tips for reducing warping. I am printing with weed trimmer line, and the stuff really likes to warp alot. So much that it actually peels the blue tape off of my bed. Therefore the brim will only help it stick to the tape. I am printing the stuff with my Printrbot at 230 C on a 100 C bed. I have seen the posts on using perf board to hold parts down, and I wonder how deformed the bottom surface looks. If anyone has some pictures that would be great. Maybe I could use a raft, but that is a huge pain. Another option I have is to create a heated chamber, which I could bring up to around 150 C so that the parts don't warp. This is not preferred since it is complicated and would restrict access to the nozzle. If anyone has any other ways of getting rid of warping, please post them here. Any and all ideas are welcome. On another note, I would also like to extend the orifice length on my machine to reduce the ooze from the nozzle. I would either like to somehow create an extension to fit on my existing nozzle, or buy another nozzle with a longer orifice. I am not sure what size nozzle fits a printrbot, or what orifice length the existing nozzle has. If anyone has this information that would be great. https://reprap.org/forum/read.php?1,144311,144311#msg-144311 Sun, 13 Sep 2026 16:48:17 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,144311,144344#msg-144344 https://reprap.org/forum/read.php?1,144311,144344#msg-144344 Dark Alchemist General Tue, 24 Jul 2012 00:33:40 -0400 https://reprap.org/forum/read.php?1,144311,144343#msg-144343 https://reprap.org/forum/read.php?1,144311,144343#msg-144343 galaxyman7 General Tue, 24 Jul 2012 00:24:48 -0400 https://reprap.org/forum/read.php?1,144311,144342#msg-144342 https://reprap.org/forum/read.php?1,144311,144342#msg-144342 galaxyman7 General Tue, 24 Jul 2012 00:11:20 -0400 https://reprap.org/forum/read.php?1,144311,144324#msg-144324 https://reprap.org/forum/read.php?1,144311,144324#msg-144324 Dark Alchemist General Mon, 23 Jul 2012 21:30:26 -0400 https://reprap.org/forum/read.php?1,144311,144317#msg-144317 https://reprap.org/forum/read.php?1,144311,144317#msg-144317 galaxyman7 General Mon, 23 Jul 2012 20:12:22 -0400 https://reprap.org/forum/read.php?1,144311,144316#msg-144316 https://reprap.org/forum/read.php?1,144311,144316#msg-144316 Dark Alchemist General Mon, 23 Jul 2012 20:03:43 -0400 https://reprap.org/forum/read.php?1,144311,144313#msg-144313 https://reprap.org/forum/read.php?1,144311,144313#msg-144313 galaxyman7 General Mon, 23 Jul 2012 19:51:27 -0400 https://reprap.org/forum/read.php?1,144311,144311#msg-144311 https://reprap.org/forum/read.php?1,144311,144311#msg-144311
