Move the specified axes to new coordinates at an optional speed, limited to the max speed of the machine. Coordinates may be Absolute or Relative depending on the positioning mode ([G90](#g90-set-to-absolute-positioning) / [G91](#g91-set-to-relative-positioning)). Absolute positioning is the default for RepRap machines.

###G90: Set to Absolute Positioning
### G90: Set to Absolute Positioning
Set the machine positioning to use Absolute coordinates (the default). In this mode movement coordinates specify the absolute destination. This is the preferred mode because relative positioning is prone to cumulative errors due to imperfect floating point precision.
Usage: G90
### G91: Set to Relative Positioning
Set the machine positioning to use Relative coordinates. In this mode movement coordinates specify the relative movement, starting from 0 in every axis. This mode is not often produced by slicers, but may be used in start/end g-code sequences, script-generated g-code, or in other special cases.
Usage: G91
