Back to C0 B0 after Cxx Bxx

[ahaslam]

I have tried working with my dealer on this but I am not having very good luck on explaining what I need or something. I was hoping it would be an easy fix but maybe it isn't possible. In mastercam I program the part to B0 C0, then I flip it side ways to B90 B150.  Then I flip it back to B0 C0. When I go back to B0 C0 the posted code only moves B and not C. The code works but it kinda freaks every one out. I know it is a time saver and isn't really hurting any thing but I would like to just go back to c zero

 

Here is the code.

N1
G0 G91 G28 Z0
T2 M6
G61.1
( G59  WORK COORDINATE )
G0 G17 G40 G80 G90 G94 G98 G49
G59 X-1.6903 Y-.3171 S3500 M3
G303 C150. B90.
G43 H2 Z4.2628 T2
/M8
G4 P1000
(FACE DRILLED SURFACE)
Z1.8628
G1 Z1.7528 F40.
(deleted code not relevant)
G0 Z4.2628
Z5.035
(FACE DRILLED SURFACE)
X1.0326 Y1.0778
G303 C150. B0.
Z2.635
(end)

As you can see, B0 C150. Can I do something to move it back to C0?

 

Thanks for the feed back.

There is a switch in the post: 'frc_cinit', which forces the rotaries back to Zero, but it only does this in the call to 'pretract' at the Tool Change.

 

I typically add code that checks to see if 'B' (secondary) is at zero, then force 'C' to zero, output both, and update the 'prv_' values.

Thanks Colin,

 

How do I force C to zero with out affecting the modality of the code? if I force it in the post wont the NCI still be reading at C150?
