Adding homing switches to the Sienci Mill One, by Troy

With Troy’s instructable, you can now add homing switches to your Sienci Mill One!

What are homing switches? Homing switches allow a machine to touch off of each end of the axis to help find the absolute position within the unit. When the Mill One is first turned on, the current location in which it is at is considered the origin (0,0,0). Until the origin is reset, the machine will consider the movement of the axis to be relative to that origin point. By homing the machine, we can reset the machine to call the same physical position of the endmill to be the origin.

While in most cases, homing switches are not necessary, but in some cases, they can be useful. In a case where you want to make the same part over and over again, it is possible to make a jig to clamp the material in the same position on the bed. By homing the machine, you can set up the Mill One to start milling in the same location of the material every time. This is just one example.
