This project provides a custom mounting solution for upgrading the Monoprice Select Mini v2 3D printer with a BigTreeTech SKR Pico mainboard and a Raspberry Pi 3A(+).
The SKR Pico can handle 12v and 24v, so I took the opportunity to replace the stock power supply with a 24v brick. If you go this route you will either need to switch to 24v fans, or install buck converters. Since my hotend fan had a bad bearing, I replaced it, and just kept the stock enclosure fan.
The mount is designed to securely hold both the SKR Pico and Raspberry Pi, with three configuration options to accommodate your power needs:
No Buck Converter Mount: Intended for those who plan to replace both fans inside the printer with 24v models.
Single Buck Converter Mount: For those who need to mount one LM2596 buck converter for power regulation.
Dual Buck Converter Mount: For more complex setups requiring two LM2596 buck converters.
Configuring Klipper
Install Raspberry Pi OS Lite (64 bit)
