One additional note:
If you upgrade the stock A4988 drivers to other drivers like 2208s or 2224s, there is a chance that motor rotation direction could be wrong (backwards) for those axis. That either requires simply moving the wiring order in the connector socket (swap the 2 wires at either end of the socket) or flashing alternate firmware from source code. Again, the fundamental difference, X and Y are already TMC2100s stock. As such, they are already wired reverse compared to what happens if you plug in an A4988 (just one of those minor differences between series or brands of stepper drivers). I'm not talking about orientation of the actual driver in the socket- I mean the 4 pin wire from the motor as it plugs into the mainboard by each stepper driver socket.
Are there markings or features on the motors that would tell us if we need to do this pin-swap ? (Like the Bondtech upgrade has specific instructions WRT if you have the "black motors" or "silver motors" on your original Raise3D extruder assembly)
I bought a pair of 2224s but haven't had time to install them yet. I read about John's travails with getting the chips oriented correctly, so I know not to do that now
