This project shows you how to convert any ordinary slider to an Arduino controlled motorized slider. The slider can move very fast at 6m/min, but also incredibly slow.
I reccomend you watch the video to get a good introduction.
Things you need:
A drill press or handheld drill
The stepper motor needs to be mounted underneath the track. The closer to the end, the longer your length of travel. The easiest way to transfer the hole pattern from the motor to the track is by tracing it with painters paint. This is a very useful tip for all kinds of applications.
The pulleys were quite high, so I had to drill large holes to accomondate for some of their height inside the track. That can be easily done with a drillpress and a stepped drill bit.
Make sure you use a center punch to mark the locations of the holes. This makes drilling them easier and more precise.
A 90° chamfer bit cleans up the edges nicely.
