Post Processor Help

Trying to convert the fagor.cps - Generic Fagor post into a 5-axis simultaneous post processor.  I found the "How to make a 3 axis post processor from the HSM post processor library support 4 or 5 axis motion" help page.  ( <http://help.autodesk.com/view/fusion360/ENU/?caas=caas%2Fsfdcarticles%2Fsfdcarticles%2FHow-to-make-a... ) Followed every instruction to the best of my knowledge and it is still posting an error.  I'll give the details needed to complete the transformation and I'll post a pic of what I have entered in the 'function onOpen' section of the post.  

 

(The tool path being posted is located in the 'CAM Samples' folder.  In the 'Ultimate' folder: 'Multi-Axis Contour - Tool Path'.)

 

Router Specifications:  5 - axis Continuous, TCP Availability, C and B axis are the (rotating and tilting) 4th and 5th axis. C-AXIS rotates around the Z-AXIS, B-AXIS tilts across the Y-AXIS.  The b and c axis are at the 'head' not the 'table'.  

 

Range: C-axis = (0 , 360)

            B-axis = (-120,120)Fagor Generic Post.PNGFaulty Post Setting.PNG

UPDATE!!!!! 

 

I figured out how to post the tool path; however it only works with my c-axis range set to (-360, 360).  My C-Axis rotation range (0, 360) will not allow me to generate a tool path without a rewind move.  I checked other post (pocket cnc, etc.) for rewind moves but im still not sure how to imput the source code into the fagor generic post.

Maybe these can help:

Those are 5-axis fagor posts for a router.

C axis rotating in the negative direction will not work.  Is there a limit and rewind function I can add to the post?

It looks like when gotContinuousCAxis is set to false then it is (-360,360), when its set to true its (0,360)?  When i change this value to true it will not post a tool path.  Am I interpreting this correctly?

No.

When it's set to true it means the C-axis can go round without stopping.

So it can do 700 degrees in one movement for example. But usually, it will only output within 0 and 360. 

 

 

In the post processors I linked there is rewind logic.

So they should just work if you give the Axis settings your machine needs.
