WebBasic work offsets are very simple to specify: simply enter one of G54, G55, G56, G57, G58, or G59. Most machine startup with G54 selected. It’s a good practice to put a G54 into the safety line at the top of all of your g-code programs to make sure you know what work offset is being used unless you have reason to want to leave that aside.

"WebSep 29, 2016 · The farther away you go, the closer the expected distance value converges to the offset distance. 10 units away gives me 10.027, and 100.005 for 100 units away. Regardless of offset, the expected distance is only equal to the radius of the circle when the circle is at the origin, and the value only increases the further out the circle is.
