Alternatively, if you want to reuse the original screen placement here is a mount designed by Ocean.The sd card reader prevents mounting the board in the stock position. You will need a way to mount the board in the stock case.In Marlin mode, it looks like the Ender 3 interface, and in Touchscreen Mode it’s like the stock interface. This screen is neat because you can switch between Marlin mode and Touchscreen Mode. The V3 of this screen has the scroll wheel on the side, that’s what the version differences are. You can use the stock screen but why would you? You’ll be losing out on so much functionality that using the stock screen would be a disservice to this upgrade. BIGTREETECH TFT35 V3.0 Upgrade Touch Screen Controller Display with WiFi Port for SKR Mini E3 and SKR E3 3D Printer Motherboard: This is the screen that will interface with the SKR board.You can use other stepper drivers and even reuse the stock AT2100 stepper drivers, the TMC2209's are just what I ended up using. I think they use less power and are quieter. You can get just the board without the stepper drivers but TMC2209’s are the better version of TMC2208’s.

This particular item has TMC2209’s included. The stock board is an 8-bit board and this one is 32-bit with a bunch of better features like sensorless homing and UART.
