Example:
SCALE.0 = 1000 : REM Scale to mm
PRECISIONINCREMENT.0 = 10.0 : REM Distance between compensation values 10.0 mm
If the axis is scaled to mm, then the theoretical distance between the tables values is 10.0 mm.

Description:
Leadscrew compensation has two modes of operation, single table mode and dual table mode.
_lsTABLE A leadscrew compensation table is defined with the PRECISIONTABLE keyword.
This single table is used to calculate position corrections, regardless of the direction
of travel along the table. A precision table must be specified prior to turning the
compensation on. Backlash compensation can be used in conjunction with single
table mode to account for changes in direction.
_lsDUAL_TABLE Two leadscrew compensation tables are defined with the PRECISIONTABLE
keyword. The forward table is used for travel along the table in a forward direction,
the reverse table is used for travel in a reverse direction. Forward and reverse
direction are based on how the table is specified. It is assumed that the tables relate
to the leadscrew as:
A B
