Post Problem draw vectors and SD

Hey everyone,

I built a polargraph with arduino MEGA R3, a cnc shield, a servomotor and two nema 23 steppermotors.

The arduino is powerd by a power supply of 12v 5A and a BEC convert 12v to 5v.

The system have a 2G SD and no screen.

When I generate the norwegian pixel technique ... everything works perfect.

But if I try to draw vectors ... with files that weigh 1 or 2 megabytes, the process break after starting at random points.

As a curiosity, if I touch the mass of the SD reader with my hand ... the work is resumed.

I suspect that it is some fault in the reading of the SD, did any of you have the same?

Thank you very much!

Does it work fine if you remove the SD reader and do everything over USB?
