RepRap vs. Marlin Firmware

[AutoWiz]

There are better chips now for the same or comparable money. BigTreeTech has the SKR PRO and the BTT002 mainboards that use a STM32F407 chip. It is cortex-M4 cpu @ 168mhz over the 100mhz of the lpc1768 or the 120mhz of the lpc1769. And both of those are only cortex-M3 anyways. I have one of each of those mainboards on the way. I already have one SKR pro and that is what is going to drive the Diamond Hotend 3 into 1 mixing printer. They just released a new revision of it. The 1.2. I do not know what the difference is. they look the same but mine says 1.1. Either way it is under $50 for 168mhz cortex-M4 cpu: https://www.biqu.equipment/products/...cf1aa7f4&_ss=r . The BTT002 mainboard is designed to be a direct replacement for the Prusa MK3S and brags on supporting multifarious screens and all sorts of other junk and i thought with that i might be able to have both the MMU2S and a touchscreen at the same time.
