Checksum Errors Bad Expectations

I created a very simple file in Easel. When I load the file and start an Air Pass the following is showing up in the log window.

Despite all the errors, the milling appears to be functioning correctly on the Air Pass.

I would do a hard reset on your computer, interface, and BoXZY itself (remove USB and main power from BoXZY), then try again. It's possible there may be a cumulative communications timing error, assuming BoXZY has been left powered for excessive periods of time. Even with main power off, BoXZY's control board remains powered through the USB, if it's left plugged in.
