i am building a prusa mendel i3 with sanguino 1.3a and everything was working perfectly when all the motors decided to stop working. whenever i use the manual controls with repetier host all the motors do is twitch in all directions. they where working fine before. i am using sprinter firmware i just re did all the wiring to see if it was that but it wasn't. Any suggestions? :S https://reprap.org/forum/read.php?158,230002,230002#msg-230002 Tue, 15 Sep 2026 19:55:32 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?158,230002,231472#msg-231472 https://reprap.org/forum/read.php?158,230002,231472#msg-231472 Hallestman Sanguino(lolu) Wed, 31 Jul 2013 10:02:36 -0400 https://reprap.org/forum/read.php?158,230002,231300#msg-231300 https://reprap.org/forum/read.php?158,230002,231300#msg-231300
Since you have temperature reading and host communication, your microcontroller should also be fine.

Is it possible that while you were working on the firmware you accidentally modified the pin assignments? Can you try marlin just to see if it works?]]> lajos Sanguino(lolu) Tue, 30 Jul 2013 21:04:50 -0400 https://reprap.org/forum/read.php?158,230002,231227#msg-231227 https://reprap.org/forum/read.php?158,230002,231227#msg-231227 Hallestman Sanguino(lolu) Tue, 30 Jul 2013 15:02:32 -0400 https://reprap.org/forum/read.php?158,230002,230953#msg-230953 https://reprap.org/forum/read.php?158,230002,230953#msg-230953
Have you tried a different firmware or at least re-uploading the one you use currently?]]> lajos Sanguino(lolu) Mon, 29 Jul 2013 18:35:27 -0400 https://reprap.org/forum/read.php?158,230002,230209#msg-230209 https://reprap.org/forum/read.php?158,230002,230209#msg-230209 Hallestman Sanguino(lolu) Fri, 26 Jul 2013 18:27:01 -0400 https://reprap.org/forum/read.php?158,230002,230201#msg-230201 https://reprap.org/forum/read.php?158,230002,230201#msg-230201 lajos Sanguino(lolu) Fri, 26 Jul 2013 17:18:35 -0400 https://reprap.org/forum/read.php?158,230002,230002#msg-230002 https://reprap.org/forum/read.php?158,230002,230002#msg-230002 Hallestman Sanguino(lolu) Fri, 26 Jul 2013 00:31:59 -0400
