 When you enter a value, the CNC executes the number of passes
required to get from the H (StartHgt) to the Z (ZDepth), cutting the
B (DepthCut) on each pass.
 When you enter an S (FinStock) value, the CNC leaves the specified
stock on the profile and depth for a finish pass. The CNC cuts the
rectangle to the M (Length), W (Width), and Z (ZDepth) dimensions
on the finish pass. Enter a negative S (FinStock) to leave the finish
stock without making a finish pass.
 When you do not enter a J (RoughFeed) or K (FinFeed), the CNC
executes feed moves at the current feedrate. J (RoughFeed)
controls the feedrate of the roughing cycle. K (FinFeed) controls the
feedrate of the finishing cycle.
 G-code format: G172
Field Code Description
CornerRad U Corner radius setting. If the programmer
enters a negative value, both direction of
cut and the starting and endpoints reverse.
ZFeed I Z-axis feedrate.
Rough
Feed J Rough-pass feedrate.
FinFeed K Finish-pass feedrate.
DepthCut B Maximum Z-axis increment used for each
pass.
FinStock S Amount of stock left by the machine before
the finish pass. Default: 0. If the
programmer enters a negative value, the
CNC leaves the stock without making a
finish pass.
