Here is a link to the parameter dump when in mm mode:

I primarily work in in/lb/sec as that is how my brain was trained… hope this isn’t a source of issue. Please note that I don’t have a “pre-update” parameter list in mm.
For G-Code sending I use Chilipeppr.
I am not sure how to regenerate the Gcode with circles sent as 2 arcs… is this an option in the sender?
