How to modify 5axiskins from BC head to AC head was created by jschulze
Hi,
I was hoping somebody might be able to help me with modifying the 5axiskins kinematics to rotate the B axis 90deg and rename it to A axis. I have everything moving and working with the 5axiskins and switchkins, but to match up with my machine setup I have to rotate and offset the B axis 90deg.

As an alternative have a look at
'sim/axis/vismach/5axis/table-rotary_spindle-rotary-nutating/xyzbca-trsrn_twp/xyzbca-trsrn.ini' which uses 'xyzbca_trsrn.comp'
Set 'xyzbca_trsrn_kins.nut-angle' to 90°
'sim/axis/vismach/5axis/table-rotary_spindle-rotary-nutating/xyzbca-trsrn_twp/xyzbca-trsrn.ini' which uses 'xyzbca_trsrn.comp'

Thanks. I'll have a look at it.

I don't have the sim/axis/vismach/5axis/table-rotary_spindle-rotary-nutating/xyzbca-trsrn_twp/ listed in my sample configurations. I was able to find the thread where you're discussing it and I downloaded the files, but I'm not able to get it to run. I found the readme filed and tried to follow the instructions, but I went wrong somewhere.
Added photo: This is how my machine is setup. It's a bit silly because I have two "C" axis setup. Specifically I want to use it to make drums so I wanted the rotary table to keep round things more concentric than just interpolating a circle.

Ah, yes, I forgot, that sim config and kinematic is only available in the 'master' version.
[Edit]
you could install 'xyzbca_trsrn.comp' in your current version 2.9.4 using the 'halcompile' tool (you might need to install the 'linuxcnc-uspace-dev' package first):then you can change to the folder containing 'xyzbca_trsrn.comp' and run
The 'xyzbca_trsrn' kinematic is now installed on your system and you could copy the simulation folder
github.com/LinuxCNC/linuxcnc/tree/master...ndle-rotary-nutating
to your system.

The required kinematic component can be found here:

So sorry to be a pain, but I got everything downloaded and got the sim to run, but for the life of me I can't get it to come out of estop. I did have to change the permissions on the python files to mark them as executable to get it to run, so maybe there's something I did there. Is there any change in the estop behavior of the master version compared to 2.9.4?
EDIT: Disregard this. I gave up and just updated my install to the master and except for a couple errors for missing iocontrol.lube stuff it started right up.
