I enter all of my G-codes, and everytime it begins the cycle, it feeds down to the final cut of the rough ( .01 on Dia, and .005 on faces still remains ) immediately, instead of doing the usual Linear cut. Here is my Code :
G01 Z0.1 X3.8
G71 U0.02 R0.1
G71 P1 Q2 U0.01 W0.005 F0.008
N1 G01
X1.15
G03 X1.25 Z-0.05 R0.05
G01 Z-.425
G02 X1.35 Z-.475 R0.05
G01 X2.90
G03 X3.0 Z-0.525 R0.05
N2 G01 Z-1.41
Thanks for the help, I hope I can figure this out...
Try this somehow your program doesn't work right. I think because N1 mess up.
G00 Z0.1 X3.8
G71 U0.02 R0.1
G71 P1 Q2 U0.01 W0.005 F0.008
N1 G0X1.15
G01Z0
G03 X1.25 Z-0.05 R0.05
G01 Z-.425
G02 X1.35 Z-.475 R0.05
G01 X2.90
G03 X3.0 Z-0.525 R0.05

The best way to learn is trial error.
