feat: Indexed (4th) axis features

[pmzandbergen]

1. Configurable indexed axis: A by default, optionally B (BC)
2. Capability to swap 4th axis between X (default) and Y (BC)
3. Support for cylindrical stock (WIP)

I've added features 1 and 2 to fix some difficulties with the Snapmaker Artisan. It is using B as a rotary axis and the rotary axis is aligned with the Y axis.

Feature 3, supporting cylindrical stock, prevents unnecessary (air) cutting.

look for the AXISMAP and SCALE features under CAM macros for an existing way to accomplish this https://docs.grid.space/kiri-moto/gcode-macros

AXISMAP is indeed a way to solve the A -> B issue. Swapping X and Y using AXISMAP when using the rotary on the Y axis is, in my opinion, risky. A user can easily forget to remove this marco when the rotary is not being used.

Or can I use the "Reset A" for this purpose? If so, I'll remove the axis alignment features and just focus on the cylindrical stock (which seems to be working OK on my machine).

Tested, it needs to be in the header. Maybe add some kind of constraint, depending on whether the fourth axis is enabled or not.

Summary

• Swapping A <-> B and X <-> Y is already possible
• Swapping X <-> Y is invisible in the UI which could be improved
• Would be nice if the AXISMAP macro (or any macro) can be enabled / disabled based on device parameters (e.g. 4th axis being enabled or disabled). This is not a real must-have since you would need a separate device profile anyway
• Cylindrical stock is a new feature
