I replaced the main board with a MKS SBase. It's a 32 bit board the runs Smoothieware. You can pick up the board and touch screen for around $75 on Aliexpress. It's a great upgrade. I highly recommend it. Changing the firmware and configuration is very easy with Smoothieware. You don't have to deal with Adruino at all.
