I deleted my original message to make it shorter. Sorry. Two questions on this MCU Protocol Error. This happens when I try to use my accelerometer on my Ender 3 Pro (Creality 4.2.7 board).

My error message lists two things that need to be updated. Does "mcu" refer to my Creality 4.2.7 board? If so, and when I reflash firmware, will that take care of needing to update the "USB-ADXL345"?

The reason I'm questioning this is because I saw a couple people with a similar error message, but their messages listed "rpi" that needed to be updated. I don't remember doing anything with my RPi, but it was a while ago. If it's just reflashing firmware to my 4.2.7 board, I should be able to do that.

What does the error tells you?
Right, mcu and ADXL. It's most likely only the ADXL. You can check that by commenting out the ADXL part again in your printer.cfg. If everything works again. It's the adxl
