[feature] Arc speed profile with jerk control #8

Closed lromor closed 7 years ago

Hello Everyone, do you have any thoughts about how to add jerk in the speed profile in order to smooth-out the accelerations and avoid machine trashing (for example for the arcs)?

bigguiness commented 8 years ago

The latest update to the planner seems to cover this issue. It's not actually accounting for jerk but the accelerations are now smooth. Can this issue be closed?

hzeller commented 8 years ago

Yeah, let's close this for now: the main part - arcs smoothing - is working now thanks to great work by Hartley. The jerk planning is a thing on the development TODO list.

Henner, this still needs to be closed. ;-)
