Arduino Mega

I'm looking for a G Code "executer" for my Arduino mega and ramps 1.4 board for a spherical coordinate system, not cartesional. I know the cartesional conversion to spherical but I cannot find any script that makes the stepper motors move in spherical way. In the end I want the robot arm to draw with a pen.

Okay can you explain what your problem is and can you post your Code here so we can hep you

I'm trying to look for a code that executes G code with arduino mega and ramps V 1.4

Are you aware of the program called GRBL?

...R

Does it make the G Code into spherical coordination?

I haven’t a clue. Read the documentation.
