Testing MK4 Issues

I've updated the firmware from Mk3 to Mk4, and added the OLED display. I'm getting unexpected results when pressing the switch. More often than not, when I press the switch, I get a "No Command" response on the display. It then displays "Clear", and finally it displays "Idle" a few seconds later.

Aside from that, I can only seem to get it to go to T0 one of ten times, if that. No matter how long I hold the switch, that is all I can ever get most of the time. Several times I get a message "Press to load T0", or "Press to unload T0", and then it may show "Cutting". Not sure why it would show cutting if I don't yet have the servo attached.

I'm not sure what I'm doing wrong, so any ideas would be helpful.

Feeling pretty confused. 😥

It sounds like the clock wasn't set properly using the Bootloader. Just try to reinstall it again, but make sure the Bootloader is successful before trying the firmware.

Not !00% sure. Will go back and follow one of the posts to make sure I have.

I went through it again and made sure the bootloader was done. I did notice that when loading the firmware the first time, I did not include the ":i" at the end. Not sure what that flag is supposed to do, but this time I made sure to include it. Whether or not that made the difference, I'm not sure. But this time it is appears to be working as expected.

Thanks for the suggestion Joseph. Never hurts to keep trying until you get it right. 🤣
