fairly consistent, error margin is less than 0.1mm.
your mounting point positions please consider the following:
- The Limit Switch
will need to be positioned where the roller and lever
will be pressed down against
the switches actuator at or near the end of an Axis's
- The switch will
require wiring, pleas allow room/provisions for that.
The switch relies on a mechanical movement to activate,
make sure it has sufficient room to do so.
- Do not run wires directly over or on the Limit
Switch as they may fowl or become caught in it's
There are no
hard rules on where or how a limit switch should be
positioned, in fact there are probably dozens of ways
this can be done. They can be place on moving parts or on
the stationary frame of your machine as long as the switch
going to come in contact with a surface that will activate
it. Below are some possible places a switch can be mounted.
switches are mounted on the Y axis's drive bar. As the drive
bar moves back and forth the switches will contact
the inside of the frame and would be tripped at each end of
it's travel. They also could have been mounted on the frame
itself and be contact by the drive bar to activate.
In the X Axis
example the switches are mounted on the back of the Z Axis
and will contact either side of the X as it moves left and
In this example
there was no good place to mount the Limit Switches where
they would naturally travel to an edge so a block (shown
in green) has been added. The function of the block it to
trip the limit switches as it moves up or down.
Once you have
selected the desired positions to mount the Limit Switches please
drill 2 x 3mm holes as per the
mounting template. Switch
orientation is at your discretion.
Align the bottom mounting point up with the lower
The lower mounting point is fixed
and the upper has some adjustment space.
3mm screws and then tighten.
Once the screws are
tightened grasp the Limit Switch and make sure it is firmly in
The Limit switch
is now mounted, repeat steps for other switches. Remember
left facing switches will have there
You are now
ready to move onto the next step:
