A 3D Printer I bought for part. It's super fast but needs a new hotend and motion controller (the old one is super super super old) and I love Klipper now! Not much to say about this one yet. Its been on the backburner while Im working on other projects.  

Interesting find

I think the printer used a custom Linux kernel to do motion control and then feeds commands to the stepper driver board because it prints at speeds that are far faster than what a AVR-based mainboard can handle.
