LinuxCNC S-Curve Accelerations

have a look here

forum.linuxcnc.org/38-general-linuxcnc-q...oth-velocity-profile and here github.com/rmu75/linuxcnc/tree/rs_6otp

Don't have much time at the moment, but I'm working on it (slowly).

Hey,

i have looked for an implementation of S-Curve on LinuxCNC and stumbled on this thread: emc-developers.narkive.com/jxJvsPLF/jerk...ted-trajectory#post4

It seems that someone made an s-curve trajectorian planer in the year 2012! Have a look at his git: github.com/araisrobo/linuxcnc/blob/maste.../emc/kinematics/tp.c

Moreover it seems to work:

Is there a way to commit this implementation to the current version of LinuxCNC? Sadly i have not the abbilitys to realize this.

EDIT: i have found another post where they linked to his repo with newer code: github.com/araisrobo/machinekit/tree/rpi2-spi/src/emc/tp

At the time of the branch started, (IIRC) it was jerk limited but only one block look ahead and didn't do spindle sync quite properly.

I believe it would be difficult to incorporate it without being an expert on the current multi-block look ahead planner.

Any news on this?

No. As far as I know nobody is looking at finite-jerk with the current multi-block lookahead TP.

Anyone interested in making this a reality? i guess lot of people should have time on their hand right now, I'd be ok to hire someone to do this for the community, PM me if you are interested!
