Rotate, Mirror, and/or Scale a sub-program

Use RMS blocks to Rotate, Mirror, and/or Scale sub-programs. These functions turn off when the sub-program ends.

Select "Other Cycles" and then "RMS" from the pop-up menu.

Conversational format: RMS

Patterns commanded by the program can be rotated using polar coordinates. Any angle can be described as positive or negative, depending on how it is referenced. CCW from 0 degrees is positive. CW from 0 degrees is negative.

G-code formats: G68

Mirroring reverses the sign (+/-) of subsequent numbers and movements, resulting in a reflection of the original pattern.

G-code formats: G100

Use Scaling to enlarge or reduce patterns commanded by the program. If a variable word is not given, it is assumed to be x1 factor. Axes for circular motion must have the same factor.

Tool length offsets, diameter offsets, tool wear factors, and tool diameter compensation are not affected by scaling.

G-code format: G72

Field	Code	Description
Sub#	P	The number designation of the
		sub-program to be used. (required)
#Loops	M	The number of times the sub-program will
		execute before returning back to the main
		program.
StartAngle	F	Polar degree angle which the pattern will
		rotate for the first Loop. Defaults to same
		as Angle.
Angle	C	Polar degree angle which the pattern will
		rotate for the remaining Loops. Defaults to
		same as StartAngle.
XCenter	I	X-Axis coordinate for the point of rotation,
		the point about which rotation occurs.
YCenter	J	Y-Axis coordinate for the point of rotation,
		the point about which rotation occurs.
