Robotarm controll via RAMPS Ardunio

Hello I installed Linux CNC yesterday after searched for CNC controlling software via linux. I am actually building an open source Robot Arm www.bcn3dtechnologies.com/en/bcn3d-moveo...-future-of-learning/ The basis of the control hardware is 3d printer technic: Arduino Mega 2560 an a Ramps 1.4 Stepper driver board. I searched the forum for Ramps using but didn`t find anything (I am curious about that).
Is it possible to control an Arduino with Ramps 1.4 board via Linux CNC?

In a word no.
LinuxCNC is a motion controller and your Arduino is one too.
Whilst it might be possible to get 2 systems talking to each other, it will be more trouble than its worth.
With Linuxcnc, either use a parallel port board or some of the third party boards such as those from Mesa or Pico Systems. These have more inputs and step generators than a parallel port which might be more appropriate for a robot arm. Eg, I use a Mesa 7i76e ethernet board with 5 stepgens, 32 inputs and 16 outputs plus 2 MPG inputs and a spindle controller before I count all of the daughter cards that could be added to it.

Thank you for the quick info. I should have a closer look on this things to understand the differences. So the next Step could be to change the little arduino with bigger boards.

Hi,

Look at this page: Moveo kinematic
(you need to register in order to access the ini/hal files)
The simulation configuration seems to work with Moveo D-H parameters calculated. I installed the vismach sim config and after some modifications I was able to move the arms.
Hopefully the details are enough to start the parport setup too.
