I’ve been running klipper on my ender v3 se for the past few weeks and its been amazing, but I havent been able to get my rpi camera to work, so I decided to rebuild klipper.
Now Im getting totally stuck on this mcu error and not sure how to resolve. I have already dropped baud rate to the proper level in config (which fixed this issue for me last time)
My only thought is that maybe my reflash is not taking on the printer, but Im not sure how to tell if that’s the case or not. Hoping someone could scan the klippy log and find the fix (Im a bit out of my league here!)
My understanding is that I can use either ttyUSB0 or the other serial. In any case, I have tried both and neither resolve the issue.
As for baud rate, this is a setting specific to this ender board. I ran into this problem when I set up klipper initially and changing it from 250000 to 115200 fixed the issue entirely. For sake of argument, I just tried it at 250000 again and returned the same result.
So, its still something else. Any other ideas?
Also btw, I know reflashing has nothing to do with the camera. I reflashed because my serial ports on my other rpi board were bad, so I bought a new one and rebuilt everything from scratch. Assumed I needed to reflash after that. Perhaps I did not?
Hey @Sineos, thanks for this. Still not working. Posting new logs here, getting the same error. I also just started everything over from scratch, this time using the mainsail OS image for RPI (versus kiauh) and still getting the same result.
