Trajectory Planner using Ruckig Lib

But i heard, when a,b,c are involved it falls back to no look ahead mode.

Yes that is true, it does not make much sense for multiaxis. Would only be of interest for XYZ axes.
Getting advanced look ahead/ velocity blending for multiaxis working is pretty much a prerequisite for multiaxis operation.
 

I'm just thinking that a XYZ jerk limit smoothing 'postprocess' app would enable people to test the algorithm.

Let's put this is on the list. We could output a gcode file with a certain mm resolution. This is the easyest way.
I will not split a g2 in multiple G2's with different a,b,c values.

Ok i just tested when there is only a,b,c move with no xyz. This now works.
When there are xyz values it will interpolate the abc over it. But with tiny xyz values and huge abc values, there i have not
yet a solution for in the code.




 

Hi,

For fun i made some video's of the 5 axis tooldir blending.
I typed some gcode lines for xyz and added some abc values in radians to it.
Some of these blending really blow's my mind. It can just filter out complete rotations on a & b axis....

Hi,

Thanks for the likes.

I made a test for tangential knife and for 3d plasma cut correction for 5 axis.

Here we demonstrate how to use the c axis to rotate a knife along the gcode path.
In the same flow it's possible to do side cut correction for a plasma application. Here we could use a gcode macro to
tell if it's an inside or outside contour, The realtime trajectory planner can then do the correction to inwards or outwards.

So on the list is reading gcode macro's to tell the trajectory planner different stuff.

Potentially very useful, indeed.
