ARC Welder Support (in my case, Ender 5 Pro)

Not sure if it is enabled. According to the Developer, a G2 command will let you see if you have ARC Welder support enabled or not. A G2 on my system (using the latest firmware via the Firmware Builder) causes a firmware error to be reported in OctoPrint.

THANKS!!

It is enabled on most builds by default.
