X-axis Limit Switches

Here are the last two limit switches (x-axis)

These 2 limit switches travel on the gantry and trip on the belt tensioners. Now to gather up the wiring and wire it through the controller and build the code to recognise the switches. Since I am using a printer port/cable to connect the PC to the controller, I will use something like the “paper out” line to detect a limit switch being tripped.
