********************************

Welcome back to Aurora Tech Channel. Today, I will take a look at the new Big Tree Tech SKR Mini E3 version 3.0. This is a drop-in upgrade for older generations of Creality printers, like the Ender-3, Ender-3 Pro, Ender-5, Ender-5 Pro, and CR-10.

Like the previous versions of Mini E3 version 2, it’s a 32-bit board with TMC2209 silent stepper drivers. There are a few improvements in this latest version.

After this upgrade, the print quality and the print speed will stay the same, but you will get a silent board and an extra fan port to control the hotend fan, it's no longer always on when the printer is not printing or heating. Now, it’s completely silent. Besides that, you also get some extension ports, so you can connect a touch screen that supports even more features.

I hope you found this video helpful.
