A follow up to a previous post, this is a listing of all the chinese 3D printer motherboards I could find, along with their CPU. I’m noticing that STM32 is overwhelmingly the most popular choice. Additionally, the STM32F103ZET6 seems to be the most popular selected CPU as well. Considering alternate firmware options for these boards, … [Read more…]

USB Type-C, or USB-C as it is commonly called, promises a lot, but also brings along a lot of compromises, confusion, and catches. For … [Read more…]
So today, I have yet another post about JGAurora – this is the next chapter in the JGAurora 3D printer story for me, and I’m not yet sure of how things will end. So, to introduce the context of this story, late last year, JGAurora sent me their latest (at the time) JGAurora A5 printer … [Read more…]
