I'm trying to replace a few parts on my printer but I'm getting delamination when i put in a linear bearing. Extruding at 240 with the bed at 110. Should the hotend be hotter? And printing with ABS.[attachment 34926 delam1.jpg][attachment 34927 delam2.jpg] https://reprap.org/forum/read.php?262,369838,369838#msg-369838 Sat, 15 Aug 2026 03:33:30 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,369838,370228#msg-370228 https://reprap.org/forum/read.php?262,369838,370228#msg-370228 Dreadnaught426 Printing Sun, 15 Jun 2014 15:48:01 -0400 https://reprap.org/forum/read.php?262,369838,370208#msg-370208 https://reprap.org/forum/read.php?262,369838,370208#msg-370208 As for bridges, from nozzle development i learned that bridges become best with very thin, pointy nozzles, like the airbrush nozzles i use in the Merlin Hotend. Flatter nozzles will make it easier to create smooth surfaces by "ironing" them though. Another important thing is that the nozzle bore has to be really straight with no uneven edges, regardless ho small. When exrtuding in air the molten filament has to drop down absolutely straight for best results, any curling will make the results worse.
Cheers

[attachment 34969 circle1.jpg][attachment 34970 circle2.jpg]Maybe related, but when i try to print something with a vertical circle it has a problem up top with bridging. My nozzle is .5mm. I'm very, very, very new to this so I'm learning as i go.]]> Dreadnaught426 Printing Sun, 15 Jun 2014 14:48:24 -0400 https://reprap.org/forum/read.php?262,369838,370176#msg-370176 https://reprap.org/forum/read.php?262,369838,370176#msg-370176 In your case i would print a test tower with increasing temperatures and check how stable they are and how well the printed shape is. I can recommend this with every new material you get.]]> Srek Printing Sun, 15 Jun 2014 13:13:38 -0400 https://reprap.org/forum/read.php?262,369838,370151#msg-370151 https://reprap.org/forum/read.php?262,369838,370151#msg-370151 Dreadnaught426 Printing Sun, 15 Jun 2014 12:19:43 -0400 https://reprap.org/forum/read.php?262,369838,370084#msg-370084 https://reprap.org/forum/read.php?262,369838,370084#msg-370084 The break itself is due to the hole not having the correct dimensions/shape though.]]> Srek Printing Sun, 15 Jun 2014 08:35:32 -0400 https://reprap.org/forum/read.php?262,369838,369932#msg-369932 https://reprap.org/forum/read.php?262,369838,369932#msg-369932 TheTechnicalNoob Printing Sat, 14 Jun 2014 16:39:40 -0400 https://reprap.org/forum/read.php?262,369838,369838#msg-369838 https://reprap.org/forum/read.php?262,369838,369838#msg-369838 Dreadnaught426 Printing Sat, 14 Jun 2014 12:22:01 -0400
