For probe compensation batch reading would be far more useful than compiled in,
then it becomes simple to read the compensation file for any stylus
you change too.

Hi Jeff,
Sorry, I probably didn't phrase it right. I understand that deceleration
on soft limits for joints on a non cartesian machine is a computational
nightmare. What I am after is to specify soft limits in world space,
just like a cartesian machine. I am interested in it for my lathe but i

It seems likely to be a very simple kinematics module, and so will
probably compile easily with halcompile.
At that point it might

No, it's not currently possible. It would be a welcome topic for
improvement.
Right now, kinematics is confined to the realtime trajectory planner, so
nothing is known about it at the time soft limits are being enforced in
task.
A naive approach would be to put a copy of kinematics into tas

There is a HAL module for that:

Is there an option to make soft limits to work in world space on a

Hi Andy,
Putting the Z axis position into the input of "lincurve" could give
you an output to apply as an offset to the X position command.
You need to go both ways. You need to offset the command and do a
reverse offset on the feedback. Yes, I could use the generated offset
then add extra m

How many axes are you using?

It attempts to keep the insert tip tangential to the programmed path.
