Subject: Re: [MachCNC] arc question

To answer my own question maybe. It looks like I am j are relatibe so they
should not be offset

I have some gcode that I wrote a long time ago, using cambam, I think. It
made the circles for me so I did not need to understand G code arcs. Over
the years I have move the circular pockets relative to each other by using
offsets.

I want to get rid of the offsets for various reasons. I still am not clear
on arcs but is moving the location of an arc less complicated than I think
it may be? Here is an example. I use G52 to set the X and Y offsets. To move
the circle without using offsets do I just need to add the offsets to all X
and Y coordinates and add the X offset to the I and the Y offset to the J.

I hope it is that easy :)

G52 X 0.01 Y .6125
