Screw error comp isn't really applicable, but you can do something similar in HAL. You want (if I understand correctly) a compensation value that applies a minor tweak to Z as X moves, right?
Yes, that's exactly what I'm looking for. Minor dips and humps in the table that I'd like to have some software correction for. I only have the two axes, X and Z on the machine. It's a saw beveler that cuts a tapered triangular bamboo strip.
You could use the lincurve HAL component to calculate the compensation amount and the offset component to apply it to the Z axis. http://linuxcnc.org/docs/html/man/man9/lincurve.9.html http://linuxcnc.org/docs/html/man/man9/offset.9.html
Thanks. I'll look into that. Any links you know of that show how I might implement that?
