I have fully assembled my prusa i3 from folgertech but i can't manually move the axis's. The hotend came with a bad thermistor. I really dont know whats wrong. Everything homes. Here's the code that folgertech included for the printer. Sorry if i miss-formated this post.

Hi! I have the same printer and I'm very happy with it (see the photos and stuff in my signature!).

Please let me know how yours is set up and I'll fix your Marlin!

Where is your X-axis limit switch? (left or right)
Where is your Y-axis limit switch? (front or back)
Where is your Z-axis limit switch? (top or bottom)

OK. Here's some pictures to help describe the locations.
y end stop is in the front right

x is on the right

z is on the bottom right

A couple more things:

Please run M303 E-1 C8 S90 and let me know the values it provides:

Kp =
Ki =
Kd =

Also, make sure your Y end stop is plugged into the 4th set of pins (Y-max) - It looks like you have it plugged into the 3rd set (Y-min)

You'll need to move the Y end stop plug up to the next set of pins.

Rename the existing Configuration.h file (in the Marlin directory) to something like OldConfiguration.h and save the attached file in the same directory to replace the old one.

The command is G-Code. It can be run in the command prompt of Pronterface or Repetier Host.

How do i replace the thermistor setting for the hotend? The hotend thermistor was DOA when i got the kit, so i bought a 3950 to replace the dead one.

Sorry - We're using different versions of Marlin. Please attach your Configuration.h file and I'll update it with these settings.

OK. Can you add the 3950 thermistor to the hotend on my firmware?
I think this is the problem in the code but i dont know for sure.

#ifndef ENDSTOPPULLUPS
  // fine Enstop settings: Individual Pullups. will be ignord if ENDSTOPPULLUPS is defined
  #define ENDSTOPPULLUP_XMAX
  #define ENDSTOPPULLUP_YMAX
  #define ENDSTOPPULLUP_ZMAX
  #define ENDSTOPPULLUP_XMIN
  #define ENDSTOPPULLUP_YMIN
  //#define ENDSTOPPULLUP_ZMIN
#endif

#ifdef ENDSTOPPULLUPS
//  #define ENDSTOPPULLUP_XMAX
//  #define ENDSTOPPULLUP_YMAX
//  #define ENDSTOPPULLUP_ZMAX
  #define ENDSTOPPULLUP_XMIN
  #define ENDSTOPPULLUP_YMIN
  #define ENDSTOPPULLUP_ZMIN
#endif

Sure, but keep in mind that it is set up for my printer, as below:

190 x 190 bed (since I am now using corner clips for my heated bed glass)
Servo mounted Z probe
All axes are using min end stops

I just got a error message in arduino.

Arduino: 1.6.0 (Windows 7), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Marlin.ino:1:20: fatal error: U8glib.h: No such file or directory
compilation terminated.
Error compiling.

  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.

Oh. You'll need to add the library in your Arduino IDE.

Download the library here: U8glib zip file and save it to your desktop (or wherever you can easily find it).

Then, launch the Arduino IDE and click Sketch > Import Library... > Add Library... and select the zip file.

This installs the bitmap and text support for LCD displays, and should remedy the compile error.

Thank you for the quick reponce. I am now 99% sure that im having a hardware problem. Its either the ramps board or the hotend thermistor thats causing my problems.

Thank you soo much. Today i replaced the hotend thermistor with a working 3950 and now i can move the axis manually and heat up both extruder and bed. I also found out today that the original one wasnt attached on both wires. It was a manufacture defect because the soldered wire broke on one side.
