[FR] [6axis_dev] 6 axes broken with certain configs and G-codes. Add Sanity checks!

[DerAndere1]

Description

Marlin support for 6 axes (XYZIJK + E) works only for certain configs and only a subset of G-codes is supported at the moment. I suggest to collect a whitelist of working features

Expected behavior: [What you expect to happen]
add sanity checks against any non-working config settings.

Actual behavior: [What actually happens]
some config combination may not compile with NON_E_AXES > 3, some configs may compile but may not work in practice.

Additional Information

• Include a ZIP file containing your Configuration.h and Configuration_adv.h files.
• Provide pictures or links to videos that clearly demonstrate the issue.
• See How Can I Contribute for additional guidelines.

Currently the configs by hobiseven are the only ones that were tested. Below I list Individual features that may work (although not all combinations). All other config settings currently should be treated as not supported yet.

• *_DRIVER_TYPE TMC5160
• LINEAR_AXES 3
• LINEAR_AXES 4
• LINEAR_AXES 5
• EXTRUDERS 0
• EXTRUDERS 1
• EXTRUDERS 2
• [DEBUG_LEVELING;], [DEBUG_PINS;]
• [dogm display (possibly not all menus work flawlessly with axes I,J,K)]
• One stepper driver per axis
