Carbide Copper Feed Rate

1

What are the units for the feed rate for carbide copper? I selected metric at the beginning if that helps.
Looks like the default is F400 for both XY and Z, but I’m not sure what 400 means. Thanks!

You have G21, which means metric. F400 means 400 mm/min (15.75 IPM)

To add to @Tod1d’s comment. The default feedrate mode for Grbl is G94, which specifies a “unit per minute” feedrate.
