RAMPS FD with robotarm

RAMPS FD with robotarm
March 07, 2016 10:07AM
For my project I use:
-RAMPS FD V1
-Arduino Due
-Robot Training Arm CS-113

Firmware I tried:
[github.com]
[github.com]

When I connect a stepper motor with the RAMPS-FD nothing happens.
I use 12V on my powers supply.
I connected the stepper driver modules on to the ramps.

Did I make a mistake by wiring the power supply?
I connected my power supply to the stepper power connectors + / - (like you can see in the diagram).

If someone could help me out.
Thanks.

Did you modified this RAMPS-FD? If not please read [reprap.org]

I did a quick search and from what I read you send ASCII codes to the Sciento CS-113 to control it (http://pepijndevos.nl/2012/04/09/sciento-cs-113.html). So why do you need a RAMPS-FD board and 3d printer software? Do you want to make a 3d printer out of it?

I did not modify my RAMPS-FD.

This is for a school project, I want this arm hold a pencil and make a simple drawing, but my arm won't even move so I don't even know if the RAMPS-FD works or not

Why do you want to use 3d printer firmware to control your robot? You don't need that firmware or the RAMPS-FD board to control stepper motors. You only need two pins from your DUE to the stepper driver to control STEP and DIR [www.pololu.com]

// See attachments.
This are the cables of my robot-arm stepper motors, how could I connect it to the DUE?

How could I otherwise power my arm without a RAMPS?

PS: I appreciate your help.

Have a look at the pololu link.


The motor connector must be connected to the a1,a2,b1,b3 pins on the driver. The power supply you connect to VMOT and GND. Two pins from the DUE you connect to the STEP en DIR and the 3.3V or 5V from the DUE to RESET and SLEEP etc

If you use a A4988 you can follow this instruction [www.instructables.com] or this link [forum.arduino.cc] which include some sketch code to control a motor.

I have 6 stepper motors, would it be possible to power it with a .0-30V and 0-5A power supply?
