==== Z Zero ====
Z zero is done automatically with the Z zero routine.

1. Attach the Z zero fixture.
*Attach the clip to the collet nut or the tool
*Place the plate on the spoilboard or the top of the material, depending on how your file was programmed

2. Check the connection for continuity.
*Lift the plate and tap it against the tool. If input #1 flashes on screen, the connection is good. If input #1 does not flash, adjust the clip and retry.

3. Run the Z zero routine
*Tool will tap twice against the plate
*Watch the Z axis readout: if it continues scrolling downwards without stopping, the ShopBot has not detected the end of the tool. You must stop the routine and try again.
