I was about to start building an mpg, then I realized I have a problem with switching directions, I was gonna take a 1.5" aluminum cylinder and make 50 dents in the side which would make contact with a switch, Although I then dont have direction, only step.
I have seen one with the same concept, and saw him using 2 switches I wasnt sure how it worked and all, I am pretty sure it was on here but for the life of me cannot find it.
I looked into encoders, too expencive.
Whats next? I think it might be possible to hook up 2 of these switches in such a way that they send the signal one way or another, again thats still quite difficult and hard to figure out.
-edit- MPG is a manual pulse generator, for controlling a cnc with a wheel like the big name cncs have.
Let me know if you know anything.
