Field	Code	Description
Rough	J	Rough-pass feedrate
Feed
FinFeed	K	Finish-pass feedrate
FinStock	S	Amount of stock left by the machine before
		the finish pass. Default: 0. Enter a negative
		value to leave the stock without making a
		finish pass.
Side	A	Setting for cutting on the inside of the
		profile (In) or the outside (Out). Selection

If you enter B (DepthCut), the CNC executes the number of passes required to get from the H (StartHgt) to Z (ZDepth), cutting to the Depth Cut = B (Z Max.cut) 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 finishes to the entered diameter on the finish pass. Enter a negative S (FinStock) to leave the finish stock without making a finish pass.

If you do not enter a J (RoughFeed) or K (FinFeed) value, the CNC executes feed moves at the current feedrate. J controls feedrate of the roughing cycle. K controls the feedrate of the finishing cycle.
