Hello. Today me and my son bought 2 used V-minions. I´ve got one of them up and running and was able to control it and start a print. After i Updated everything i get MCU errors. I have no idea how to update the MCU. Can someone lead me in the right direction.

if you are using ratos it should have automatically flashed it for you. It makes me think that whoever had it before you didn't set up ratos correctly I would go through https://os.ratrig.com/docs/installation#preparing-your-control-board and re-flash your MCU using those instructions which should get you back to a working state

ohh you are probably using the 1.x version of ratos. That is end of life (current is 2.x, and they are incompatible with each other). Save your printer.cfg to use as reference and then do a new install of ratos (same documentation as before, just start at the beginning insted of the preparing your control board step)

Just though would be better (keep cleaner) to put my issue here, as it's a very similar one. But just for record on future consult, i had solve my problem using a new SD card, making a new installation, update all components (that properly update the MCU). Then put back the old card and it was all OK now.
