#linuxcnc-devel Logs

10:36 AM rmu: hi. just for fun, i hacked together a c2-smooth velocity profile generator into the current trajectory planner, just replacing trapezoidal profile with something smooth (5th order bezier curve)
10:38 AM rmu: so far, looks promising. there remains some excessive jerkiness when entering/exiting "circular arcs", but i have some ideas how to deal with that
10:38 AM rmu: if anybody is interested, the code is on github https://github.com/rmu75/linuxcnc/tree/rs_6otp, i would be interested if something is inherently wrong with this approach
11:13 AM seb_kuzminsky: rmu: neat!
11:49 AM rmu: it doesn't handle changing feed override or pausing at the moment
11:55 AM hazzy-lab: rmu that is awesome!
12:01 PM rmu: thanks, but don't get too excited too fast ;)
12:30 PM aircooled is now known as hazzy-lab
01:57 PM -!- #linuxcnc-devel mode set to +v by ChanServ
04:09 PM rmu: i posted HALscope screenshots of resulting position, velocity, acceleration and jerk profile for a linear move on the forum

07:56 PM skunkworks: rmu: oh - nice - I could do some testing....
07:59 PM skunkworks: if linuxcnc had a jerk limited planner - it would definatly turn heads...
