OpenSBP command - CN

[Scott216]

I'm looking at an OpenSBP post generated by Fusion 360. Can anyone tell me what these two commands do?

CN, 90
CN, 91

CN, 90 calls up the My_Variables file to set user variables from a predefined list.

CN, 91 is a check for possibly running a metric file when the software/controller is in inch mode.

I see. CN is running the scripts in the SbParts\Custom\ directory.

Yup, that it. ;)
