Subject: Issue with Arc Output – G2/G3 missing X/Y coordinates

Kiri:Moto CAM

Hi Stewart,

I’m using Kiri:Moto to generate G-code for GRBL/FluidNC via bCNC.
When “Arc Output” is enabled, Kiri sometimes generates G2/G3 arcs without X/Y target coordinates, like:

G2 I-0.2928 J2.4818

This causes error 26 in GRBL, because arcs must include a final X/Y position, even if it hasn’t changed from the previous line.

Could you modify the postprocessor to always emit X and Y on G2/G3 lines, for better GRBL compatibility?

Thanks a lot! Kiri:Moto is an amazing tool!

I’ve made a Github issue for this. It will likely come out in the next release.

Thanks for the bug report😊!
