Ought to, but doesn't very well. It's been discussed before but Linuxcnc is very choppy on same code that works perfectly on other controllers. I'm still convinced the trajectory planner is not optimal and is limited by the one line look ahead. The code I tested on does NOT contain multiple short segments, only curves and lines. It's worse with slow acceleration settings and doesn't seem to calculate what is the "best" velocity very well. >The full explanation and solution is rather involved.
