This CNC machine the easiest and cheapest way to get into the magical world of Computer Numeric Control.
It is designed to have minimal parts requirements, no support material, Fast print times, and very "Forgiving" in case of programming error.
If you are familiar with DIY CNC machines, you know they have the tendency to be... self destructive.
This design allows for ZERO damage if there is unexpected twisting, over shooting, and even if say you have to slam on the brakes and it flies across the mini van.
So if you are new, it is good to learn the ins and outs, before you leap into an expensive model.
All part are designed to print without support material, but can be printed with support.
Printed in ABS, but that was all I had on hand.
Printed on a Glass print bed with ABS Glue.
Overview and Background
Started writing down the instructions. They were long and complicated so I made a video, which make a lot more sense. The first video is how to set up an axis and the second is how to load the bearings (which should have been in the first video, but accidentally deleted it so I had to refilm it)
It is designed to have the most minimal parts list
