The USB CNC Controller has a 14 pin connector for connection to an external “Jog Controller”. This controller allows the user to move the spindle along each of its three axis, and control the speed at which the movements are made. While there were no instructions for this, a little trial and error established the connections and the necessary circuitry to perform axis movement. Even though I’m waiting for the 14 pin connectors and big fat momentary switches (on order…

The controller software has a panel in the setting menu for both positive and negative limit switches for all three axis so I needed to find the associated hardware connections.

The unit basically moves a high-speed rotary tool in three different orthogonal (90 degree) axis. The unit sits on a substantial aluminum base with an extruded aluminum bed. A heavy-duty gantry straddles this bed…
