I am working on learning Laserweb and Gcode.

I created a simple Gcode program for learning and testing.
It is supposed to make a 1" box.

This code works in my gcode simulator but as you can see by the tiny box in the lower left corner LW doesn’t seem to recognize the G20 code.

Ideas on what is wrong??
