Hey guys, I've been printing for about 6 months now, and I just recently got some new filament from a supplier I haven't bought from before. I switched over from the red colored 3mm PLA I was finishing off part way through a print to this new "natural" colored 3mm PLA, and then resumed my print. Aside from a minor offset in the resulting layers the print turned out ok, the new filament worked as I expected it to. After that print though I haven't been able to get a new print started, I'll get my hot end up to temperature, do some test extrusions that succeed, and then start the print. Sadly though, after the 30 second pre-print delay/wait period Pronterface has, my extrusion just fails before the first layer can even be laid down. I'll then pause the print and remove my feed system's bearing that holds the filament against the teeth that force it down into the hot end, and will be unable to force the filament down farther. Then I pull the filament up and find that a good portion of the bottom of the filament has been deformed. This is the first time I've experienced this, but I'm thinking perhaps the hot end is too hot and is causing the area just above the entrance to the hot end to deform and then that in turn is causing a blockage. I have my hot end set to 185C, what temp would you guys recommend I set my hot end to? Also, is it reasonable to assume that maybe because of a lack of coloring the "natural" color PLA should be set to a generally lower temp, to compensate for its less impeded heat distribution? Thanks in advance guys! https://reprap.org/forum/read.php?151,214721,214721#msg-214721 Mon, 10 Aug 2026 19:06:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,214721,215968#msg-215968 https://reprap.org/forum/read.php?151,214721,215968#msg-215968
My biggest issue with cheap PLA is getting it to stick to the bed.]]> coffee General Mendel Topics Thu, 06 Jun 2013 13:17:04 -0400 https://reprap.org/forum/read.php?151,214721,215625#msg-215625 https://reprap.org/forum/read.php?151,214721,215625#msg-215625
Let us know how it works out!]]> Karmavore General Mendel Topics Wed, 05 Jun 2013 14:56:08 -0400 https://reprap.org/forum/read.php?151,214721,214721#msg-214721 https://reprap.org/forum/read.php?151,214721,214721#msg-214721
