The long and short of it I have built a mill. I have achieved proper movement of all three axes and now need to accomplish spindle control and home\limit switches. It seems that I am missing something when using my current configuration with normally open switches. The switches are only normally open as they are industrial induction prox switches that run on 12v and I have used voltage dividers to bring the voltage signal down to 3.0 volts. I have tested using a jumper wire directly from the 3.3volt rail during a homing cycle to see if I can get any response. I am using the gshield settings when compiling. Below is the settings I am compiling with. Can anyone help me configure the homing settings? Thank you very much in advance for the help. Tinyg2 moves my machine much better than grbl and I would really like to use it.

/***************************************************************************************
* To calculate the speeds here, in Wolfram Alpha-speak:
*
* c=2*pi*r, r=0.609, d=c/360, s=((S*60)/d), S=40 for s
*
* Change r to A_RADIUS, and S to the desired speed, in mm/s or mm/s/s/s.
*
* It will return s= as the value you want to enter.
*
* If the value is over 1 million, the code will divide it by 1 million,
* so you have to pre-multiply it by 1000000.0. (The value is in millions, btw.)
*
* Note that you need these to be floating point values, so always have a .0 at the end!
