Looking good, I like the screen editor, simple and intuitive. I was able to fix many of the issues in the default screen without too much trouble. It would be good if there were some bold text that could be used on the screens, my eyesight isn't good these days. Some of the LEDs are a bit dim, hard to tell if they are on or off.
I have my profile configured for metric and notice the feed rate is still in inches, needs a conversion.
I have observed a few strange behaviours when running some of my old part programs but haven't pinned them down yet, restarting often helps. I have found that a crash will leave the core running so I need to use Task Manager to kill it before a restart will work.
Cheers
