Wide face groove with two offsets on OKUMA MULTUS U3000 with P300 control

[k.zawadzki]

Hi everybody,

I have problem with face groove. I need use two offsets, but FC don't create it.

below correct program from another CAM system. We see two offsets: OS=1 and OS=2

N0103 TD=010034 M323
N0104 G97 S330 M41 M03 M08
N0105 G00 Z3
N0106 X126.24
N0107 G00 X126.04 OS=2
N0108 G01 Z0 G42 F0.08
N0109 G03 X126.24 Z-0.1 K-0.1
N0110 G01 Z-2.1
N0111 G40 I1
N0112 G91
N0113 G01 X0.1 Z0.1
N0114 G90
N0115 G00 Z3
N0116 X135.2 OS=1
N0117 G01 Z0 G41
N0118 G02 X135 Z-0.1 K-0.1
N0119 G01 Z-2.1
N0120 G40 I-1
N0121 G01 X126.24 OS=2
N0122 G91
N0123 X0.1 Z0.1
N0124 G90
N0125 G00 Z3
N0126 M05 M09

N2325 TD=010034 OS=2 M323
N2330 G50 S2600
N2335 G96 S160
N2340 G0 X125.44 Z3.0
