Rotate C to 0

[Henry]

Hello,

what setting in "Generic Fanuc 5X Mill.pst" must be changed to get C-axis rotate back to C0°?

First operation has B-90° C180° and next should be B0°C0°.But instead it uses fastest way by rotating toolplane C180°.

Code right now:

8 L B-90. C180. F5000

9 CYCL DEF 19.0 WORKING PLANE

10 CYCL DEF 19.1 B-90. C180.

11 L X-5. Y+10. FMAX

12 L Z+100. FMAX

13 L Z+10. FMAX

14 L Y-10. Z+10. F4333.4

15 L Z+100. FMAX

16 L Z+490 FMAX M91

17 L B0. C180. F5000

18 CYCL DEF 19.0 WORKING PLANE

19 CYCL DEF 19.1 B0. C180.

20 L X+28.386 Y+25. Z+100. FMAX

 

Code should like:

18 CYCL DEF 19.0 WORKING PLANE

19 CYCL DEF 19.1 B0. C0.

20 L X-28.386 Y-25. Z+100. FMAX

Try this

search for

"frc_cinit"

and set it to 1

 

this should force a C axis reset at toolchange

[Henry]

"frc_cinit" is 1.

But there is no toolchange with new operation.

What else will switch on B0°C0°?

Hey Henry,

 

My guess is you're not using the Generic Fanuc 5X post and that you are using the DMU Heidenhain post from In House. Is that the case? If so, IH has several parameters in binary that normal humans can't change let alone see. I would suggest contacting them... Ivan helped me with our Heid post.

No I'm not using somekind of original Heidenhain post.Just trying to modify "Generic Fanuc 5X Mill.pst" for 3+2 axis.

Josh, is your 3+2 post working correctly if using

bottom WCS and some other toolplane?

[Josh T™]

My post works fine with any WCS. The rotations are correct no matter what I use: WCS or normal plane selection. I wish I could help you more with the rotational parameters but as I said, most of that stuff is in binary.
