motion channels for robotic atc library

I'm convinced extrajoints handles such a case. It can even move multiple joints at the same time, they're just not synced with each other in any way unless extra hal logic is used to interpolate moves, which you don't need here.

It would be nice to have a simple_xyz_tp.comp component to support linear interpolation and be independent of the main TP.

I think this is a simple task for extending the simple_tp component, where smoothing and arcs are not required.

thanks for the thoughts. ill be hopefully getting this ordered up in a few weeks. should be fun

I saw this in a recent PR sent by Sascha Ittner:

github.com/sittner/linuxcnc/pull/70

github.com/LinuxCNC/linuxcnc/pull/3845/c...7ac47d8c5d436a843202

Description: joint_ctrl_main.c
* Standalone HAL realtime component for single-joint control.
*
* Provides: homing, keyboard jogging, jogwheel jogging, trapezoidal
* trajectory planning, following-error monitoring, limit-switch
* handling, and backlash compensation — all as a self-contained
* HAL component independent of the full LinuxCNC motion controller.

neat. this is the current state of the robot. xyz (and call be point to point one axis at a time). a drawbar (air) and a pivot for the arm (air?) and the door opener (air?).

grr. how do i NOT embed the video? its stripping out the time index. 2:41.
