# FACING UTILITY

This program creates a gcode file that can be loaded into linuxnc to run a rectangular facing operation.

- no blank entries.
- stepover not larger than tool diameter
- Size X and Size Y are at least 2x stepover value
- spindle RPM is not 0
- feedrate is not 0
- tool diameter is not 0

- checks for valid input fields
- creates a gcode program according to the Raster setting
- if a red X remains in the display, the program will not be created

- a successfully created program can be transferred to the gcode viewer
- the program is then ready to be run in linuxcnc

The machine should be X and Y zeroed at the lower left corner of the workpiece.

The program is designed to run the selected raster pattern at a Z value of 0 in machine units. The safe travel Z level defaults to 20 mm for metric or 1 inch in imperial. These can be modified by modifying the source code.

The feedrate for Z travel defaults to 1/2 the feedrate entered for X and Y.

NOTE: It is up to the user to ensure that all entered parameters are compatible with the machine settings that the program will run on.
