Fanuc turning post processor problems

[lethal375]

Fanuc O

When I select "Use Canned Cycle" G71 the code is never correct?

Have tried type A, B, & C configuration 

Most of the problem is with Rapid to position before and after G71 lines 

Post processor output that does not work

N22 G0 Z0.005

N23 X0.35

N24 G71 U0.008 R0.01

N25 G71 P26 Q30 U-0.008 W0.004 F0.006

N26 G0 X0.574 Z0.005

Modification that works

N22 G0 X0.35 Z0.005
N23 G71 U0.008 R0.01
N25 G71 P26 Q30 U-0.008 W0.004 F0.006
N26 G0 X0.574

Am I missing something?

Hi

I recall there being issues with canned cycles if the compensation for the tool was set to "Tip" rather than "Tip tangent"

You should be using Tip Tangent in most cases anyway

Just checked and the tool compensation is as you suggested.

Is the issue that it's posting out X/Z moves on the retract, but separate X/Z moves on the approach?

[lethal375]

Not sure exactly what your asking?

Rapid moves before canned cycle are separated in 2 lines?

If combined it works

Just wondering why they are separated and if no one else is having this problem then I must be doing something wrong?

Thanks
