I'm going to try, I just can only drive the A or C, A & C axes with a G1 F50, if I move X or Y nothing happens, no movement of the A or C axes.

Is this normal?

I'm thinking about it ,

in the .ini file that I posted to me, there are connections

in the [HAL] section which I don't have in my .ini file.

Reassure me, is it just for simulation, or is it necessary to make the machine work properly ??

Thank you

That is normal.

That is just for simulation.

[edit]
I really think you should play around with the simulation that is included in your installation. There you can jog the axis and see how it is supposed to work. There are even some example gcodes.

you are right,

I will install the similation.

I also that my problem can come from the fact that I start linuxcnc in "TCP" mode and do my origins and the G54 X0 Y0 Z0 A0 C0.

I have to do my origins in "trivial" mode (trivkins and not in xyzac-trt-kins).

For that you have to program "M" codes, like "M128" to activate "TCP" & "M129" to deactivate it.

I found the docs, but I don't know where to write these little programs in the linux tree.

Best Regards

To use those M codes you need a version of LinuxCNC that allows switching kinematics. This functionality has not been merged with the main branch of linuxcnc. So in order to install that you will need to do a RIP (Run in Place) install of dewey garretts switchkins branch. This will require you to compile and build linuxcnc from source.

Here is his guide: www.panix.com/~dgarrett/stuff/s_kins_guide.txt

Thank you for all those informations.

I do not have the necessary level to do this (compliation / branch ??).

however, I saw that I could use the M66 / M68 to change the type of kinematics and synchronization of the axes.

all this with the subroutine call.

subroutine call as I have already used for the automatic measurement of my tool length.

Is it correct ?

Thank you

M66 and M68 are indeed used in the M128/M129 commands to read/write values from inside the Gcode. However the actual changing of kinematics is only possible if you run the switchkins-branch.

This is, by the way, also why I got to learn how do a RIP install. It's really not all that difficult. One just has to sit down and try.

Really all that's needed is described in the link above:

Warning: Spoiler!

You've got a nice machine, would be a shame.

Thanks, but I'm really not good on linux.

it starts well I do not have the files attached in my tree structure ...

I got to go until there.

thank you very much, but without you it's impossible to do it.

Have you completed step 2?

2) To get the source code and build LinuxCNC, see:
linuxcnc.org/docs/master/html/code/building-linuxcnc.html

Learn how to build the default (master) branch first.
You must succeed with this before proceding.

There you need to first try this:

It this fails, as it probably will, you will need to install the missing dependencies.

Maybe this helps: (I have not actually watched the whole thing)
