If you've been 3D printing for a while, you might have heard of Klipper. This custom firmware improves many 3D printers, but does take some work to install.

There's a new firmware update coming for the Raspberry Pi 4 that substantially reduces its operating temperature.

The last major release of Raspberry Pi OS was in November 2024, meaning that there are plenty of changes in this latest update, both visible and under the hood.

To take advantage of the network OS installation feature, users must first update the Raspberry Pi’s EEPROM (Electrically Erasable Programmable Read-Only Memory).

First on the list is a Raspberry Pi 4 or the newer Pi 5 running the latest bootloader firmware; earlier boards cannot boot USB devices natively.
