3d printer extruder hangs on wheels

prejudice I joined this forum in the hope that I can to help. I realizate my personal 3D printer with measures 900x900x900 xyz used (Arduino and ramp 1.4) everything works perfectly, if I create linear objects, but the strange thing is that when the printer effetua circles, not extruder extrudes the thread, and then starts to extrude the thread only when effetua linear movements. I wonder if any member of the forum this has happened to such a thing and if it managed to solve?

Some firmware doesn't support "G2 and G3" arc moves.
Maybe you see a mismatch of slicer and firmware settings?

ok well I think that's the problem but if there is a solution to solve this thing?

I've used as firmware marlin

Get the newest Marlin version here. It supports G2 and G3 moves.

Thanks for the reply
Did the test but does not work unfortunately has the same anomaly, the printer moves in a circular extruder but pauses when he makes an arc, then he resumes to extrude the thread when effetua linear, cmq perhaps I doubt that it can depend on these parameters:
// Arc interpretation settings:
#define MM_PER_ARC_SEGMENT 1
#define N_ARC_CORRECTION 25
const unsigned int dropsegments = 1;

By chance you know how to set these values so as to extrude the wire even in a circular motion?
