There was something Andy talked about that he wrote, but I don't remember
what that was. It was something in hal code if I remember correctly.
Sounds like a job for the external_offsets branch, and either a
distance sensor of some sort or the "lincurve" HAL component to apply
a fixed offset depending on axis position.
Andy,
I'm leaning towards lincurve. In order to utilize that, I've got to
upgrade linuxcnc to a bit new version. I'm running v2.5.5 right now,
but lincurve isn't in that distro. I'll be doing the upgrade over the
next day or soif lincurve will do what I need.
I couldn't find any examples of lincurve in use and the man page is a
bit thin on how to actually implement it. Also, the man page mentions
x,y coordinates. Will I be able to mapthis to and X axis position and a
Z axis height? Also where are the mapping values stored? A lookup
table in a separate file, a listing in the hal file, or something else?
I'm a bit weak on hal coding not having to write new hal stuff for a
number of years. Notreally sure how I need to implement this utility.
Do I need to use any other hal utilities to make something like this work?
Thanks for your help,
Mark
