hot end turns itself off mid print? what would cause this I have done about 7 or 8 prints since I swapped out my heater cartridge no problems at all now all of then sudden a couple of times my heater has shut itself off on its on. I felt the mosfet that was connected to it and its warm but not hot and there are no shorts in wiring. I also checked the g code to see if someone was pulling a prank lol. and I can't seem to find any issues https://reprap.org/forum/read.php?1,236365,236365#msg-236365 Mon, 05 Oct 2026 20:37:39 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,236365,238386#msg-238386 https://reprap.org/forum/read.php?1,236365,238386#msg-238386 tattooedfish General Thu, 22 Aug 2013 02:34:14 -0400 https://reprap.org/forum/read.php?1,236365,238360#msg-238360 https://reprap.org/forum/read.php?1,236365,238360#msg-238360 jamesdanielv General Wed, 21 Aug 2013 23:01:21 -0400 https://reprap.org/forum/read.php?1,236365,238353#msg-238353 https://reprap.org/forum/read.php?1,236365,238353#msg-238353 tattooedfish General Wed, 21 Aug 2013 21:58:50 -0400 https://reprap.org/forum/read.php?1,236365,238352#msg-238352 https://reprap.org/forum/read.php?1,236365,238352#msg-238352 Anonymous User General Wed, 21 Aug 2013 21:54:41 -0400 https://reprap.org/forum/read.php?1,236365,238350#msg-238350 https://reprap.org/forum/read.php?1,236365,238350#msg-238350 tattooedfish General Wed, 21 Aug 2013 21:14:27 -0400 https://reprap.org/forum/read.php?1,236365,236401#msg-236401 https://reprap.org/forum/read.php?1,236365,236401#msg-236401 Crussell General Fri, 16 Aug 2013 00:50:21 -0400 https://reprap.org/forum/read.php?1,236365,236397#msg-236397 https://reprap.org/forum/read.php?1,236365,236397#msg-236397 -------------------------------------------------------

Your host software's console should say something like "ERROR: maxtemp() triggered!" if that was happening. This could also happen if the hot end thermistor's wiring got knocked loose a bit during the upgrade and the electrical connection is spotty. The millisecond during which the circuit is broken causes the hot end temperature to read zero, and the firmware will kill the print.]]> Pointedstick General Fri, 16 Aug 2013 00:38:14 -0400 https://reprap.org/forum/read.php?1,236365,236388#msg-236388 https://reprap.org/forum/read.php?1,236365,236388#msg-236388 Crussell General Thu, 15 Aug 2013 23:43:45 -0400 https://reprap.org/forum/read.php?1,236365,236365#msg-236365 https://reprap.org/forum/read.php?1,236365,236365#msg-236365
