Please do a clean Klipper installation. It seems some modifications you have installed may interfere with Klipper, for example right now it seems you have some old or wrong version of c_helpers.so library, which normally is automatically recompiled by Klipper to include any new functionality. However it is not happening in your case. And it is infeasible to debug and find the root cause of issues on a machine with unknown set of untested modifications. If you start with clean Klipper, you can at least make sure that the generic_cartesian work and youâll get a working configuration (or not, in which case we can maybe find bugs in Klipper and actually fix them). Then if you absolutely need some additional mods, you can install them one by one, testing Klipper at each step. If you see that it breaks at some step, youâll then have an option to report the compatibility issues to the author of that modification that break Klipper.
Sooo with a small test config from chat gpt it works and also with Cartographer add on and Led effects add on but now i want to setup a config vor idex 6wd and i dont get it how it Works what i need to put where
Is it possible to make a rough config in therms of stepper and carriages
Thanks so far 
Could you please share your current printer.cfg? I am having issues setting up my tridex as well and would like to see what you did to make it work.
Iâm getting the following error when starting Klipper:
Option âmicrostepsâ in section âdual_carriage vâ must be specified
The strange thing is: I have the microsteps option defined in the [dual_carriage v] section of my config, so this error shouldnât happen.
Iâve double-checked the spelling and indentation, and everything seems correct. Could this be a parsing issue or a problem with how Klipper loads that section?
Has anyone else experienced this?

A lot of the config is from you @mandela64

This is where I am at now but have issue with dual_carriage homing. Skipping the Awd steppers for now until I get it working. I also have my z-steppers on a separate control board since I ran out of room on my kraken board.
i use the btt max ez with 10 steppers thats good in my case
can you share your config ? i can mybe use yourâs to use 6 motors and then keep going forward
So I decided I would take a shot at this:
New generic_cartesian kinematics
(incl. CoreXYU/CoreXYUV, generic IDEX and AWD)
But a quick backstory:
I happened to have won a Creality Rotary add-on for a new Laser Engraver they were promoting.
But when it came in, I went to take a picture for a shout out to @CrealityA1FalconLaser
When I snapped this photo, my mind went to another place.., but I put the idea off untill I saw this post; and decided now is good time as any.
After review of the instructions, it seems its just a standard stepper, 1:1 on the chuck. The connection is simply done by unplugging the Y stepper from the engraver, and using thier extension cable to connect it.
So⌠this project is going on is a Sovol SV03, 350x350x400
It has a Creality 2.2.1 motherboard with 5 drivers, and was intialy setup as X,Y,Z,E0,Z1
I was able to setup the new Rotary at the bed center and chose the biggest cylinder that I could find that it can hold.
My first thought was using the dual Z ports on the board to âsyncronizeâ the Y movements. it worked slightly. But I couldnt control them independantly of course. Reading where mandela64 spoke of running out of steppersâŚ
I happend to have a spare Creality 2.2.1 board, So I moved the Y stepper and endstop along with the Rotary stepper and configured the following

The key is the Rotation distance for the Rotary. It needs to match the size cylinderâs circumference. The piece Iâm using for protyping is not the best.
but the vase is ~360mm in Circumference" which coincidentially matches the size of bed it now rests on. So I set the rotation distiance to 360.
To utilize the dual carrige, I first start with the Z gantry already raised above the rotary and issue a home X and Y. Y1 then also homes after Y is done (although Iâd prefer it not to need an endstop at all.)
But for now Iâm manually triggering the endstop for Y1 (I will model an endstop mount in the near future.) I then issue the command
SET_DUAL_CARRIAGE CARRIAGE=1 AXIS=Y MODE=COPY this syncronizes the Rotary to the Bed and moves the Rotary to under the probe.
Homing Z then with [safe_home] placing the Z probe at the center of the Cylinder.
Once homing is complete. I set the Rotary carrige (y1) to primary. SET_DUAL_CARRIAGE CARRIAGE=1 AXIS=Y MODE=PRIMARY
This locks down the bed and sets the Rotary active for all Y motion.
I then run a z_tilt_adjust, this probes both ends which levels the gantry to the Cylinder (This removes the minor taper from end to end)
once complete, I run a new home z as always. and then of course run the mesh.
Once the mesh is done, I issue the command again to set the rotary to copy mode.
Then manually move the Bed/Rotary so the nozzle is over the cylinder.
one last command to set the rotary back as primary. and is now ready for printing⌠well soon anywaysâŚ
My first goal is a cylindrical Hueforge as they are only a few mm thickâŚ
As the Z layers increases, the Y movements will be more and more effected by circumfrence vs linear distance vs flow rates
Others will have to wait on some much needed non-linear slicer-ing I imagine
But I wanted to share my progress, and give a big thank you to developers for work done on the new generic_cartesian kinematics. its been fun.
YT Short of a bed meshing runâŚ
Thanks all!
One thing I havent yet figured out is how M84 (set_stepper_enable) no longer wants to disable the steppers at idle in this configurationâŚ
Quick update, I hadnt realized that the Dual Carriage config allows the 2nd stepper and endstop to be on its own mcu. I was able to put the Y stepper and endstop, back to primary mcu config. And now to add or remove the Rotary Y is just add or commenting out the include for the now designated Rotary mcu. That greatly simplifies the changes necessary to switch it out.
edit: just one last post as an update and Iâll quit hijacking this thread 
Itâs working!! I printed a 100mm(circ) cylinder first on the normal bed. And then mounted it on the Rotary and printed a 60x70x2mm flattened cube as a test.
