Ok getting a little frustrated here.... got the Homing/hard limit switches mounted upper right corner of the table and Y and X tested in wired in to the Arduino 9,10 and then 12 for the Z. The Z since I really don't have I mounted a NO push button. And pins are going the ground pin #14 when hit.
Using standard 9j, Pic Sender and GbShield. With the Homing cycle enabled, it flashes the Z axis, and I press the cheater button to tell it that its Home and time to do the rest, nothing. Even if I clear the Fault I can not jog. If I clear out the Homing cycle all is good. It will run a file at the lower left 0,0 and the PWM signal works per DVM.
So tell me, when all the G Code created in Inkscape and others want to use the lower left corner as 0,0 why am I trying to do a Homing to the upper right?
