I have a new Creality Ender 2 Pro with a Creality 4.2.3 mainboard. I'm attempting to compile Marlin to fix a bug. How can I tell what driver chips I have on this board?
I've narrowed it down to likely
TMC2208_STANDALONE or possibly the
TMC2225. Strangely Creality only has documentation for the 4.2.2 and the 4.2.7 boards (not 4.2.3)
4.2.2 => TMC2208
4.2.3 => ?
4.2.7 => TMC2225
Some say you can tell the driver just by listening to the noise it makes. Here is a video of the printer running. The motors are nearly silent to my ear.
