Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface Hello, I bought a RAMPs 1.4 and now I started to build my Prusa. Well, I wanted to try the NEMA 17 motors and I connected them to the RAMPs in this order 2A = red 2B = blue 1B = green 1A = black They don't move. I changed the option (board selection) on Sprinter firmware and I choose 33 to chose the RAMPs 1.3 (1.4 is not availabe for selection). I also tried disconnecting my endstop from board and nothing. I really don't know what I can do else. I connect the printer with my computer trough Pronterface and pressing "Connect" botton, it's fine and it gives a message that printer is now online. I also tried the test code downloaded from wiki and I just get the two leds lighting green and red, but no any movement. I'm using a power supply with 12V and 20A ATX, wich I tested it with a multimeter and it gives 11.85V. I hope you could help me with this. It's getting really upset.

Arduino IDE stepper motor library and examples have nothing to do with RAMPS and they are not expected to work with it.

thanks but I've seen so many videos & posts that uses ramps 1.4 with arduino mega 2560 & a4988 motor driver module. i want this combination to be used in my dlp printer for z axis movement only. I tried with test firmware set up worked for first but now its stopped working (may be i need to change motor). same set up did not work with marlin firmware. please help !!]]> yogesh.dp RAMPS Electronics Thu, 26 Nov 2015 05:15:37 -0500 https://reprap.org/forum/read.php?219,108510,589202#msg-589202 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,589202#msg-589202 misan RAMPS Electronics Thu, 26 Nov 2015 02:51:30 -0500 https://reprap.org/forum/read.php?219,108510,589195#msg-589195 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,589195#msg-589195 yogesh.dp RAMPS Electronics Thu, 26 Nov 2015 02:43:56 -0500 https://reprap.org/forum/read.php?219,108510,165060#msg-165060 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165060#msg-165060 misan RAMPS Electronics Thu, 08 Nov 2012 16:51:16 -0500 https://reprap.org/forum/read.php?219,108510,165051#msg-165051 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165051#msg-165051 matrhint RAMPS Electronics Thu, 08 Nov 2012 16:04:39 -0500 https://reprap.org/forum/read.php?219,108510,165049#msg-165049 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165049#msg-165049 matrhint RAMPS Electronics Thu, 08 Nov 2012 15:36:13 -0500 https://reprap.org/forum/read.php?219,108510,165044#msg-165044 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165044#msg-165044
Anyway, it is likely the default values of Marlin not to fit your hardware. Calibration is needed so motion scale is true.

Sure.]]> misan RAMPS Electronics Thu, 08 Nov 2012 14:57:39 -0500 https://reprap.org/forum/read.php?219,108510,165043#msg-165043 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165043#msg-165043 matrhint RAMPS Electronics Thu, 08 Nov 2012 14:54:14 -0500 https://reprap.org/forum/read.php?219,108510,165040#msg-165040 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165040#msg-165040 misan RAMPS Electronics Thu, 08 Nov 2012 14:31:46 -0500 https://reprap.org/forum/read.php?219,108510,165039#msg-165039 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165039#msg-165039 matrhint RAMPS Electronics Thu, 08 Nov 2012 14:29:30 -0500 https://reprap.org/forum/read.php?219,108510,165021#msg-165021 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165021#msg-165021
This makes it not to accept any motion command.

You need to fix the thermistor connection first (even if you do not plan on using the hotend yet).

Alternatively connect a 10K resistor on the thermistor inputs on the RAMPS board.

Then, try again to move the motors, I think they will run fine.]]> misan RAMPS Electronics Thu, 08 Nov 2012 12:26:09 -0500 https://reprap.org/forum/read.php?219,108510,165020#msg-165020 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,165020#msg-165020

Have you loaded any firmware to your board? If so, which one? What sorftware do you use in your PC for communicating with the board? Do you get any messsage back from the board on connecting?

If you cannot try the test code, maybe there is a problem with that code and the newest version of Arduino. Could you try that with Arduino IDE version 23?]]> misan RAMPS Electronics Thu, 08 Nov 2012 02:33:44 -0500 https://reprap.org/forum/read.php?219,108510,164939#msg-164939 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,164939#msg-164939 I am having a similar issue. I am trying to test out individual stepper drivers with one motor but nothing is working (no movement). I have the one stepper motor and driver hooked up on the X axis portion of the RAMPS. I have a 850 Watt power supply connected to the RAMPS. I believe everything has been changed correctly to make everything work. I have the feedrate set to 30 mm/s in the firmware, and have tried changing the homing direction. The motors that I am using have a current rating of 1.8A and I have set the driver to about .5V (I have tried .7V but had same results). I have all of the jumpers installed. When I use pronterface or the LCD control to home the axis, I can hear the motor make the very quiet, high frequency sound, and the shaft becomes unmovable. I have tried all of the drivers and different motors. All of the motors are the same type. From the seller of the motor they describe the wires as: A+ A- B+ and B- instead of 2B 2A 1A and 1B; I wired them as the instructions say red green yellow blue which is A+ A- B+ B-. I have been sure to keep it on for as shot of time as possible in order to keep the drivers from burning up. I would try ramps14test.ino but it will not work due to a line saying that serial is not defined.

1.
Not sure what firmware you are using, both Sprinter and Marlin have this on Configuration.h file. In Marlin look for these lines:
#define INVERT_X_DIR true // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR false // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR true // for Mendel set to false, for Orca set to true
#define INVERT_E0_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E1_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E2_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false

changing each value will intert that axis direction.
2.
If you z-axis motion is not affected by the end-stop state then I guess you have a wiring problem.]]> misan RAMPS Electronics Thu, 01 Nov 2012 08:04:24 -0400 https://reprap.org/forum/read.php?219,108510,163780#msg-163780 Re: Motors don't move RAMPs 1.4 + Arduino Mega 2560 + Sprinter Kliment + Pronterface https://reprap.org/forum/read.php?219,108510,163780#msg-163780 -------------------------------------------------------

1. Hm... where is in firmware? i think my problem where. I don`t see this settings =( Cause X-axis see a endstop then homing (push endstop - move backward, push again, goin backward a little) cab u give a small "code line" for me to i can search for this.
