Lost communication with MCU 'toolboard_t0'
Hi, I am at a loss with my Vcore 4 400, it has been plagued with Lost communication errors. It worked great for the first month and then I would get Timeout with Lost communication with MCU 'toolboard_t0' errors a few hours into prints. I replaced the USB-C cable recrimped the power to the toolboard and then the printer worked great for another month or so and now I am getting the same issue again...

Is the USB cable well attached at both ends, zip-tied to the printhead? Quality multi-strand cable so it doesn't die so fast?
Yeah this sounds like a wiring issue
Yeah it is
Why do the usb c cables fail so often?
Show us a picture of your entire cable. People have had their USB C cables for years without issues
It isn't a ton, but mines been going for ~700 hours
