I have a piece I need to cut a 180 circle out of in the Z-axis. From what I've read, this would be supported by something like this...
G91
F100
G2 X0Y0Z0 I0 J0 K-2
But when I run that, all I get is "OK" back without movement. Any ideas?

You have asked for a circle with zero radius. The arc commands work by moving to the start point, then in the g2/g3 command specifying the end point, and specifying the incremental distance in I and J words. Grbl mostly follows the gcode standard specifyed by Linuxcnc, so have a look at Linuxcnc’s reference documentation for g2 and g3 for more information.
thanks that helped... looks like needed to switch planes to XZ first and then attempt the move with I and J.

Yes, you need to change planes. Not sure if GRBL supports G18-G19 though?
