I just this morning noticed that the fan on my Prusa i3 was not running. Going further up the wires, I saw that the electrical tape at a splice had caught on the extruder gear, pulling it loose and letting the wires short. I tried several different fans on D9, but nothing works. Everything else on the printer is running fine. (except for an unrelated extruder grip issue) Have I fried a component on my RAMPS 1.4? or do I just need to reset something? https://reprap.org/forum/read.php?4,424703,424703#msg-424703 Tue, 14 Apr 2026 10:52:40 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,424703,424737#msg-424737 https://reprap.org/forum/read.php?4,424703,424737#msg-424737 Have you got 12v on D9+ ? If so, check the bottom of the Ramps board for a damaged track]]> waitaki Reprappers Mon, 27 Oct 2014 01:49:00 -0400 https://reprap.org/forum/read.php?4,424703,424718#msg-424718 https://reprap.org/forum/read.php?4,424703,424718#msg-424718 dexterousfolder Reprappers Sun, 26 Oct 2014 23:18:27 -0400 https://reprap.org/forum/read.php?4,424703,424705#msg-424705 https://reprap.org/forum/read.php?4,424703,424705#msg-424705 jbernardis Reprappers Sun, 26 Oct 2014 22:19:04 -0400 https://reprap.org/forum/read.php?4,424703,424703#msg-424703 https://reprap.org/forum/read.php?4,424703,424703#msg-424703 dexterousfolder Reprappers Sun, 26 Oct 2014 21:41:38 -0400
