Is your feature request related to a problem? Please describe.

Currently Marlin supports up to LINEAR_AXES 6. I heared of a custom printer that is built with more than 6 axes for which Marlin cannot be used at the moment. Implementation was started at DerAndere1#49 but that is outdated and we could not get the endstops to work so far. See related discussions at DerAndere1#47 and DerAndere1#44 (comment) .

Are you looking for hardware support?

Would be great to support all stepper drivers that are supported in current Marlin. Support for displays is optional for now.

Describe the feature you want

It would be nice to expand Marlin to up to 9 fully fledged non-extruder axes. Number of axes and axis names should be configurable. To see what places have to change in code, see the addition of 6 axis support (#19112).

Can I respectfully request that 6 axis gets finished first?

Ie G2/G3 work as expected with 6 axis
Also machines types other than Cartesian work with 6 axis. In particular CORE(XY|YZ|YX| etc)

I explicitly do NOT assign myself to the task of audding 9 axis support. Anyone who Does should indeed thoroughly test and Improve things for 3-6 axes, first.

7th axis (internally called M_AXIS) is working now with BED_LEVELING_3POINT, so you can now test XYZUVW A E or more axes. An interested person can try to rebase the code from my branch https:/DerAndere1/Marlin/tree/9axis_pull onto https:/MarlinFirmware/Marlin/tree/bugfix-2.0.x and report the outcome

9 axes plus extruders are compiling. A 10th axis is included for fun.
I wait until the rework of G2 / G3 PR is merged, then I can assign myself to the task of rebasing my branch.
