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.

Amazing work.
Is this available for test? I have a high speed glass cutting machine that would greatly improve his performance with this features

@Tiagounderground,

Yes, you can test or run the application in posix realtime or non-realtime.
However it is still not finished in the sence of look ahead features and more.
You can test it carefully on your machine on your own risk off course.
It has no homing features, but you can look at the hal file how to setup the axis for a xxyz machine.
Best to build the app is using the ./recompile script.
But first build& install this opencascade and clothoids
Here is the script to actually run a parport machine, this is tested ok.

To make things easyer, I made a
appimage
for hal-core. This appimage is a cnc simulator. Its valid for x64.

We already have a standard g-code G41/42 defining the compensation side. can't we use it?Here we demonstrate how to use the c axis to rotate a knife along the gcode path.

Hi Tommy,
I just made some changes to the appimage. At my pc it runs from the download dir now, wich was a problem.
Please try it again and report.
Hi Hmnijp,

Perfect point. We use that. I will code it that way.
I also have to bring in offset's soon. To zero the machine at certain point.
And i hope to start coding the fillets on the trajectory itself coming day's. Using the clothoids, then if clothoid's fails, fall
back to spline fillets.
So everything goes as planned.

@Tommy,
I was thinking about the core dump. This is kernel related.
This is my output after downloading the file. Some times i have to start the app twice before i can actually jog.
This is also the case when using not a appimage.

Run the Latency Test and resolve before continuing.
If you still keep core dump, i can edit the appimage to run Using POSIX non realtime

Just tried the updated AppImage and I also get a CoreDump on my non-RT LinuxMint machine. I then tried it on a machine with a preemt_rt kernel and when I try to start the AppImage the terminal just hangs there, no output at all.I was thinking about the core dump. This is kernel related.
