ich suche einen Postprozessor für Fusion360, welcher 5-Achs simultanfräsen in LinuxCNC ermöglicht.
Kann ich den aktuellen Postprozessor abändern? Wenn ja, wie?
Ich bitte um Hilfe.
Danke!

Have you tried the "emc" postprocessor? That is the old name for LinuxCNC.

That looks like 5 axis, right?

du kannst meinen Postprozessor benutzen, aber den musst du definitiv noch an deine Maschine anpassen. Der gibt 5 Achsen simultan aus in XYZBC und auch nur von 0-359.999 bei der Rotationsachse C sowie variieren die C-Achs befehle, je nach dem, ob er CW oder CCW drehen will in den Vorwerten. Da ich hier keine .cps Dateien hochladen kann, musst du die Text Datei von .txt zu .cps ändern. Bei Fragen kannst du auch This email address is being protected from spambots.

However, due to the way F-feed is handled in linuxcnc the result will not be so good. I made a video about that
Here is a post from Autodesk on the topic of feed rates forums.autodesk.com/t5/hsm-post-processo...ighlight/true#M14311
Another option is to change the kinematics to tcp or inverse kinematics. Described here linuxcnc.org/docs/devel/html/motion/5-axis-kinematics.html . Several 5-axis kinematics are included in linuxcnc dist, just switch "trivkins" to for example "xyzac-trt-kins" and now linuxcnc does tcp. In this case, the standard Fusion 360 post processor can be used directly, just make sure to set
optimizeMachineAngles2(0); // TCP mode. 0 = activate

There was a recent thread here about switching between the two modes so manually jog in normal Cartesian coordinates and run with inverse kinematics.
If you run the development version of LinuxCNC then you can easily switch between Joint and Axis mode.
However, jogging in TCP shouldn't be that hard, as long as you concentrate on the tool-tip, and even then you will only see anything unusual when making angular jogs.

If one is comfortable with this, tcp is the easiest way to get g-code support from Fusion 360, just a few lines to change that reflects the 4 and 5 axis config.

if (true) { // note: setup your machine here
var aAxis = createAxis({coordinate:0, table:true, axis:[-1, 0, 0], offset:[0, 0, 0], cyclic:false, range:[-10,110], preference:0});
var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, -1], offset:[0, 0.15, 0], cyclic:false, range:[-360000,360000], preference:0});
machineConfiguration = new MachineConfiguration(aAxis, cAxis);
setMachineConfiguration(machineConfiguration);
//optimizeMachineAngles2(0); // TCP mode enabled (eg. M128, TRAORI, G43.4, G243)
optimizeMachineAngles2(1); // TCP mode disable (eg. M128, TRAORI, G43.4, G243)
}

no 5Axis syncron mode
will it be implemented in the post ?
