Customer Reviews
I used OctoKlipper with a RPi 4B to operate the printer. It's survived dodgy driver chips and a thermal runaway (yep... it grounded through the thermistor wires without frying anything. Don't buy cheap heater cartridges.)
During my time with this board, I've successfully hacked together a dual he/extruder system, extra parts cooling fans, and a number of good prints.
