Hi there, I'm having some trouble getting the G68 rotating function working properly. I want to mill this slot, turn 120 degrees, mill it again, and turn it another 120 degrees and mill it the last time. But how come I get a CRC alert no. 41 when I'm milling the 3. (240degree) slot? Here's my program: :0070(WELDINGFIXTURE) (S)(HMT)(JENS) G1902 B188. D157.5 H20. I94. J78.75 K0. T22 (6MM.SGS.END-MILL) M6 G0 G90 G54.1 P20 X0 Y0 S8000 M3 G43 Z3 H22 D22 M8 M98 P0071 G68 X0 Y0 R120 M98 P0071 G68 X0 Y0 R240 M98 P0071 G69 G0 G90 Z250 M9 G0 G91 G28 Z0 Y0 M5 M30 :0071 (SUBPROGRAM FOR SLOT) G0 X0 Y-4 G0 Z-6 G1 Y-16.775 F400 G1 Y-10 G1 G41 X1.51 Y-13.51 G3 X5.01 Y-10 R3.5 G1 Y0 ,R3 G1 X-5.01 ,R3 G1 Y-16.775 G3 X5.01 Y-16.775 R5.01 G1 Y-10 G3 X1.51 Y-6.5 R3.5 G1 G40 X0 Y-10 G0 Z3 G0 X0 Y0 M99 Shouldn't it just work like a charm? Controller is a Fanuc MXP-200i Thanks Soren |

| It worked in my back plotter after I added decimal points. Code: :0070(WELDINGFIXTURE) (S)(HMT)(JENS) G1902 B188. D157.5 H20. I94. J78.75 K0.

| But to be overly critical he does not say that he tried it at 0 and 120, we are just assuming that from the program. |
