[Emc-users] Universal spindle speed control for $7

2020-06-18 Thread Chris Albertson
I'm making good progress on my 3D printed CNC conversion. I found a way to 3D print a spindle controller that should work for most small milling machines and small lathes. The cost is "almost nothing". These machines' spindles are controlled by turning a potentiometer so my new system simply

In the US, the traditional system uses teeth per inch. but the problem with this system is "where do you place the tape measure?" The answer is NOT around the outside of the gear. You need to place the tape such that it runs inside the teeth. this is hard to do. Also here is a quiz:You
