[marlin-bugfix-2.0]

Thank you for all your hard work developing and maintaining the Marlin codebase!

Marlin has support for CNC coordinate systems, which is most appreciated.

[CNC_Coordinate_Systems] can be enabled in [configuration_adv.h] to enable G53-G59 coordinate systems:

/**
* CNC Coordinate Systems
*
* Enables G53 and G54-G59.3 commands to select coordinate systems
* and G92.1 to reset the workspace to native machine space.
*
#define CNC_COORDINATE_SYSTEMS

Marlin is increasingly used for CNC machines i.e. MPCNC.

Popular Gcode parsers like CNC.js and LinuxCNC use "G10 L20 P1 X0" and "G10 L20 P1 Y0" to set a new origin for G54 work (offset) coordinates.

Marlin already supports G53 machine coordinates and G54-G59 work (offset) coordinates but unfortunately does not support G10 L20 P1 X0 Y0 Z0.

A more detailed explanation:
https://github.com/synthetos/g2/wiki/Gcode-Coordinate-Offsets

G10 L20 P1 X0 Y0 Z0 simply requires Marlin to execute the following:

  1. G54
  2. G92 X0 Y0 Z0
  3. Return to original coordinate system.
