the beam when moving down the side of the beam.
Default: 5 mm (0.197 in)
RENC[18] Default measurement resolution (feedrate-per-rev.).
Typically 0.001 mm (0.0001 in) feed per revolution.
The larger the value, the less accurate measurements
will be.
Default: 0.002 mm (0.0001 in)
RENC[19] Default spindle speed.
Measurement cycles are optimised for a spindle speed
of 3150 rev/min.
Some tools, e.g. those that are unbalanced or large,
must be run at speeds less than 3150 rev/min. This is
the responsibility of the user. Use the R19= input to set
speed.
Measurement cycle times increase with slower speeds.
The minimum speed is 800 rev/min.
Default value: 3150 rev/min
RENC[21] Beam axis.

If the laser beam is parallel to the X-axis, select 1.
If the laser beam is parallel to the Y-axis, select 2.
If the laser beam is parallel to the Z-axis, select 3.
If the X-axis is to be used for radial measurement,
select 1.
If the Y-axis is to be used for radial measurement,
select 2.
