Hello! I am a noob when it comes to printing, but I know the basics.I was given a Prusa Mendel i1, and I was told it was working and ready to go. Anyway, I am having some major issues, first, the thermistor reports NEGATIVE temps and the extruder doesn't heat up at all. The stepper motor controllers are some pololu ones, I was told, but they use a TI chip. The stepper motor themselves aren't working very well, they make noises but don't move or move extremely slow no matter how much I adjust the POT on the drivers. Currently, I have an Azteeg X3 board with the Repetier firmware on it. Can I have some assistance or suggestions? Pics to follow soon. https://reprap.org/forum/read.php?262,361941,361941#msg-361941 Wed, 16 Sep 2026 21:34:21 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,361941,362896#msg-362896 https://reprap.org/forum/read.php?262,361941,362896#msg-362896 Dirty Steve Printing Sat, 31 May 2014 00:05:41 -0400 https://reprap.org/forum/read.php?262,361941,362360#msg-362360 https://reprap.org/forum/read.php?262,361941,362360#msg-362360 myprusasucks Printing Thu, 29 May 2014 22:13:53 -0400 https://reprap.org/forum/read.php?262,361941,361941#msg-361941 https://reprap.org/forum/read.php?262,361941,361941#msg-361941 myprusasucks Printing Wed, 28 May 2014 22:32:16 -0400
