LinuxCNC Documentation Wiki: JointAxesBranch

This page describes the .ini config changes needed to run the joints_axes branches.

The joints_axes branches need some (fairly straightforward) changes your .ini file, and master and 2.5 won't run with those changes. So i suggest that you copy your foo.ini file to (for example) foo-ja3.ini and make your changes in the ja3 version of your ini. That way you'll be able to go back and forth between ja3 and the regular branches whenever you want to, by starting linuxcnc with the two different .ini files.

I may have missed some ini changes, if something doesn't work let us know (on the mailing list) and i'll try to update these instructions.

Add KINS

Add this section. Change the JOINTS value to however many joints your machine has.

    [KINS]
    JOINTS = 3
    KINEMATICS = trivkins

Split the [AXIS_*] sections

Split all the [AXIS_n] sections into [AXIS_X] and [JOINT_0], [AXIS_Y] and [JOINT_1], etc.

The [AXIS_*] sections get the HOME variable.
The [JOINT_*] sections get all the other variables.
The MAX_VELOCITY and MAX_ACCELERATION variables should be duplicated in both [AXIS_*] and [JOINT_*].
