Long story short, I’ve been building a Frankenstein printer (P3steel) out of old parts. I had a lot of problems with this RAMPS 1.4 hat where some axis would stop working occasionally, needing a reboot and then finally, it burnt out the USB chip (16U2) on my Arduino Mega.

Rather getting a new mega and continuing to use this cheap ramps board, I’m looking to get a new board.

I use a raspberry pi to drive the board (Klipper). So 32 bit isn’t important to me. I’m looking for a decent board with decent protection against burning itself out. What should I get?
