I often let my Sherline CNC mill run a job, but wanted to have the spindle motor shut off automatically when the cycle was completed and the Z-axis returned to the home position. That way if I didn't come back right away, the spindle motor wouldn't continue to run. I wired an additional on/off toggle switch into the line current and rigged it to be tripped by the raising of the headstock. I included a spring in the chain to dampen the movement. I looked around and didn't see anything like this on the market, so I made this device myself for my Sherline mill. The principle is simple and is similar in concept to the auto-stop on my Lortone lapidary slab saw. Setup is pretty easy, and the idea is that for certain tasks you can set up your CNC mill, adjust the final Z setting and then walk away to do other tasks. The auto-stop turns off the drill head when the job is complete. I'm using a millimeter mill, so I adjust my final Z stop to be 20 mm. The initial starting point for the Z is 6 mm. Standard chain length is 12 inches but other lengths can be supplied also for no extra charge. Email me after ordering to do this. This device was made for a standard Sherline Mill but could probably be adapted to fit other brands as well. Note that the switch box needs to be secured to either your table or board that your mill is mounted on. I have my mill bolted down to a solid 3/4 inch hardwood board.
