I need a help with GCODE for mach3.


I am trying to cut helix by series of G2 arcs, but I get short stop after every circle.
When I try only circles without Z movement, then it works nice, without pauses between circles.

Am I doing something wrong?
I don't know GCODE very well, is there some better way to write it?



G90 G54 G21 G17 G80 G43

G91
G64
#200=7


(with Z movement included, it makes short pause after every circle)

G2 I[#200] J0 Z-1.5
G2 I[#200] J0 Z-1.5
G2 I[#200] J0 Z-1.5


(without Z movement it works smooth)

G2 I[#200] J0
G2 I[#200] J0
G2 I[#200] J0
