Install the proximity switches
The proximity switches are used to calibrate the XY location of the tool, and also signal the tool to stop movement
before hitting the mechanical end stops. They are triggered by a steel target (in this case, a hex bolt).
Start by installing the X axis switch targets on the
rear table side
. Slide one of the T-nuts into the lower middle
groove of the extrusion. Thread a hex nut onto one of the hex bolts, add a flat washer, and then loosely thread the
bolt into the T-nut. Adjust the position of this assembly according to the diagram below. Tighten the bolt into the
T-nut and then tighten the hex nut down against the extrusion.
