Mount the mechanical end stops and proximity switches
Mechanical end stops
The mechanical end stops primarily exist to stop the gantry from
rolling off the table. When properly installed, they are also a
useful tool for squaring the gantry to the table frame.
The Y axis stops have already been installed, but we will fine-tune
their position later in the installation.
For the X axis, the stops will mount to the outside of each table
side using the T-nuts and socket head screws included in the bag
marked “end stops.”
You will also need the 1/8” hex key that came with your pinion
gears.
This image shows the position of the stops at the far end of the X axis (away from the home position).
Loosely attach the included hardware to the stop blocks and then slide them into place on each end of the
outside
of the table sides.
Carefully roll the gantry to one end of the table until the wheels are resting within 1/4” of the end of the X
rails. Put a clamp on the rail to hold the car in place at that position.
Slide the stop blocks so that they are tight against the pinions on the two X motors.
Tighten the bolts to lock the stop blocks into place.
Repeat this step at the other end of the table.
