output NURBS

Creator

Hello,

 

i wanted to output nurbs interpolation due to memory limitation in the CNC controller. I cannot get my postproc to work. I have already added custom commands like cmd_nurbs_init and cmd_nurbs_poly and cmd_nurbs_spline. Still, post is not outputting proper code.

Post is attached.

thank you for your help

Have you tried to choose Nurbs in Motion Output Type settings of the Machine Control?

I think there is a problem with attachments of forum for the time being.

You set our operation with no Part and Blank Geomerty, right?

 

This is what I get with it:

N410 ;Cutting
N420 Y18.194
N430 F2.
N440 BSPLINE SD=3 Y-89.844 Z-15.215 PL=0.0
N450 Y-92.485 Z-4.62 PL=.507467
N460 Y-99.501 Z3.731 PL=.492533
N470 Y-103.684 Z6.883 PL=0.0

And without it, I get only Arc/Line moves.

 

It seems to be essential to have Geometry Group with your operation.
