    No due to how the machine moves and it’s location in the room i need it to be ymax. I got it figured out just had to use some nchannel fets to with the signal wires of the switches going to the gates of the fets and then they would pull the io pin of the due to ground I’ll see if i can get a video uploaded shortly to explain. thanks for your help.

    Also another important detail i am not using a gshield board just the pinout.
    I am unable to use gshield because the motors and size of the machine require 4.2 amp steppers. so currently i have 6 pins in use for step and direction. 2 more for spindle pwm and enable. and the remaining 3 for Xmin Ymax and Zmax.

    Thank you for the fast response. I think you are right with the pull up resistors. when I used a jumper to short the input pin to ground I got a response out of the machine. Do you by any chance know if it is possible to reconfigure the pull up resistors to pull down?

    The limit switch signal reads 0V when no metal is put in front and 12V when metal is if front.
