I am with Phill. Halscope.


Halscope can save data files.

But as far as I can see it can't open them. It has a menu option, but it is disabled. I haven't tried enabling it, to see if it leads to any import code.

It's a shame, being able to exchange raw halscope data would be rather useful.

I would really like to see a comparison between your last result and the changes I suggested in this post


This a 25mm square cut in 4.82mm plate at 635mm/min. Here is a visual of the cut path.




This is cut with the original algorithm.



This is the new algorithm.

The second one looks smooth !
At the end on the second picture the z feedback goes very high, does the z axis actually move that far up?
It is puzzling as on the screenshots there is 100m/div on that z axis feedback, so moving 400m is somehow unreal.
Or am I missing something ?

My machine is in imperial units, that's the part that you are missing.

Did you use the same Kerf Override values for both cuts or did you try the second one at 100%
