Hi Schematicsman

if you have the jumper J1 set for using the boards +5V supply
you don't need to add any resistors - that's why I removed them from the original diagram

as to how you physically wire the switches it depends on what connectors you have fitted to the control box


very often you find "aviation" connectors are used on Chinese control boxes
the boxes having a number of holes for 4 limit switches and a probe
blanked off by a paper label when the connectors have not been installed

a photo of your box will help

if you fit four 2 pin connectors
then one pin on each connector is connected to the common ground
then printer port pins 10 ,11, 12, 13 can be connected to the remaining connector terminals
pin 15 can go to your E-stop switch

I will add more later when I return home

PS

this is the typical connectors found on Chinese control boxes
note – the danger of mains voltage on chassis mounting plugs !!!


from other posts
some other DIY options that have been used are
either pass the limit switch cable through a strain relief or
used a terminal block fastened to the box






once I know what you have and what method you want to use
either wire the limit switches directly to the breakout board or go via connectors mounted on the box
I will add more diagrams of the wiring
