How ?

open the attached file, which includes a 540°(1.5 circle) arc.

Bugs

1: the preview image only shows 0.5 circle; 2: it runs 0.5 circle in simulation, but 1.5 circle in real machine.

preview: image

Too bad, the P-value in G2 X165.0 Y132.0 I44 J22 P2 is not supported by original grbl (https://github.com/gnea/grbl) and also not supported by GRBL-Plotter. Original grbl gives this error: 

< error:36  Unused value words found in block.
! Last processed 'G2X165.0Y132.0I44J22P2'  line-Nr:24

Can't you use a post-processor to avoid the P-word?
