Hi, I had an old Marlin firmware (uploaded on June 2014) which I decided to upgrade today. I made changes in configuration.h and configuration_adv.h to suit my machine (custom built) and when I uploaded it I got a mintemp error on startup. This, of course, prevents printing as it doesn't allow me to increase the hotend's temperature. The mintemp error is generally generated if there is a problem with the termistor connection, so I have checked if there was a problem but couldn't detect it. I uploaded my old firmware and the error disappeared so it is certainly a configuration problem, but I am not able to find it. Any ideas? https://reprap.org/forum/read.php?4,493135,493135#msg-493135 Wed, 13 May 2026 03:24:57 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,493135,493622#msg-493622 https://reprap.org/forum/read.php?4,493135,493622#msg-493622
Just post your issue in the testers needed section and see if someone found a solution for it, if not just open a new bug fix request.

I spend over 4 hours trying to make my auto bed leveling work and after pulling all the hairs of my head went back to old version.]]> ggherbaz Reprappers Mon, 06 Apr 2015 17:51:32 -0400 https://reprap.org/forum/read.php?4,493135,493135#msg-493135 https://reprap.org/forum/read.php?4,493135,493135#msg-493135
