I have a folger tech i3 prusa 3d printer, and it was working properly until after a print, then I started to get the hot end temperature readings for bto the hot end and the heated bed. So when I heated the bed nothing would happen. But when I heated the hot end both temperature readings started to rise. The thermistors are in good shape and after switching connections I realized that the T1 connection on my 2560 board is the one misfunctioning. I have been messing with the firmware configuration.h file but I can't get itbto work. Any suggestions? https://reprap.org/forum/read.php?1,664628,664628#msg-664628 Sat, 10 Oct 2026 16:33:27 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,664628,665069#msg-665069 https://reprap.org/forum/read.php?1,664628,665069#msg-665069 github.com]

ie in the file pins_RAMPS_14.h

#define TEMP_0_PIN 13 // ANALOG NUMBERING
#define TEMP_1_PIN 15 // ANALOG NUMBERING

and a bit lower down

#define TEMP_BED_PIN 14 // ANALOG NUMBERING

t0 is pin 13
t1 is pin 14
t2 is pin 15

Just swap these as needed..

ie to swap t1 and t2 change the following
#define TEMP_1_PIN 14 // ANALOG NUMBERING
#define TEMP_BED_PIN 15 // ANALOG NUMBERING]]> Dust General Wed, 18 May 2016 02:46:43 -0400 https://reprap.org/forum/read.php?1,664628,665056#msg-665056 https://reprap.org/forum/read.php?1,664628,665056#msg-665056 leomireles007 General Wed, 18 May 2016 01:47:40 -0400 https://reprap.org/forum/read.php?1,664628,664770#msg-664770 https://reprap.org/forum/read.php?1,664628,664770#msg-664770 ggherbaz General Tue, 17 May 2016 08:38:23 -0400 https://reprap.org/forum/read.php?1,664628,664628#msg-664628 https://reprap.org/forum/read.php?1,664628,664628#msg-664628 leomireles007 General Mon, 16 May 2016 22:26:32 -0400
