5Axis Kinetic from 2.8 on 2.7x

If you are still using 2.7 for a new build when 2.8 is finally about to be released, you will be in a world of pain trying to use V 2.8 components with V 2.7. They are just sooo different.

IF your machine requires V2.8 features, upgrade.
If your hardware does not manage to run it, upgrade it.

Good morning all ,
Already, Thank you for responding so quickly.
I present you my problems:

In fact my machine works very correctly in 3 axes and 5 positioned axes.
where it gets complicated is the operation in 5 continuous axes.

In fact to be honest, I work with as CFAO fusion 360 where there is a ready post processor configured, where there are only a few parameters to change. ( section “function onOpen()”)

After configuring the axes in the post processor ,as I said above, everything works well except the 5 continuous axes, where the trajectories are totally random.

In fact, I don't know if it comes from configuring my post processor or configuring linuxCNC?

Already my first questions are:

Can I perform continuous 5-axis with the LinuxCNC configuration that I attached in my last post?

Do I have to go through modules ("5axeskins" / "xyzac-trt-king") in the LinuxCNC configuration (TCP)?

Is my Fusion 360 “file.cps” post processor incorrectly configured?

I attach mom file ("Post processor") if you want to take a look.

Thanks a lot for your help.

Since your config works for 3+2 I would expect it to work for 5 axis operation as well.

For Tool point coordinated operation you need to provide xyzac-trt-kins with the physical offsets of the pivots of your A and C axis. If these values are not correct then the matrix calculations done in the kinematic file will be all wrong and the tool motion all over the place.

In your config you have set:

net :tool-offset motion.tooloffset.z xyzac-trt-kins.tool-offset
setp xyzac-trt-kins.x-offset 36.056
setp xyzac-trt-kins.y-offset 0
setp xyzac-trt-kins.z-offset 0

which seems wrong to me as the rotational axis of a is along the x axis. Why would you have an x-offset?

Have you looked through this:
docplayer.net/49845107-5-axis-machine-to...ion-in-linuxcnc.html

Also note that there is a simulation configuration for the xyzac-trt-kin in the sim folder.

I don't have any experience with Fusion360 so I don't know if you can or need to configure your pivot offsets in the post processor.

It might be worth to start out with testing 4axis simutaneous operation and then go on to 5 axis

I think there is confusion between version 2.7.14 and 2.8.
I am working under Dabian with version 2.7.14 pre installed in "real time".
The 5 axis modules are not the same.
“5axiskins” for version 2.7.14
“xyzac-trt-kings” for version 2.8.

except, the parameters passed for the axis offsets do not work from version 2.8 to 2.7.14.except, the parameters passed for the axis offsets do not work from version 2.8 to 2.7.14.

example linuxcnc 2.7.14:
net: tool-offset motion.tooloffset.z 5axiskins.tool-offset
setp 5axiskins.x-offset 0
setp 5axiskins.y-offset 0
setp 5axiskins.z-offset 36.056

This does not work, an error message appears when starting linux.
Linuxcnc 2.8 hal :

net: tool-offset motion.tooloffset.z xyzac-trt-kins.tool-offset
setp tooloffset.z xyzac-trt-kins.x-offset 0
setp tooloffset.z xyzac-trt-kins.y-offset 0
setp tooloffset.z xyzac-trt-kins.z-offset 36.056


My problem is that the CNC control PC is not connected to the internet, and even I don't know how to upgrade Lcnc 2.7.14 to 2.8. I'm not sure "Synaptic" will be installed under the Dabian version.

Thank you for your help

Thank you very much

Yes, my apologies. There is a fair bit of difference from 2.7 to 2.8. I only work with 2.8.

This does not work, an error message appears when starting linux.

What does the message say?

As rod said, you might want to upgrade to 2.8. You have to set your repository:

buildbot.linuxcnc.org/

Or, download a new image if you want:
forum.linuxcnc.org/9-installing-linuxcnc...ver-mint-iso?start=0

Be aware though that you will have to adjust your configuration for version 2.8 because of the distinction between joints and axis.

Hello , thank you very much .I will try updating my system from 2.7.14 to 2.8
