To make sure I am reading your post corrector. The Z homes and reset  to 0 without hitting limit switch.( home in the incorrect position) That sound like you have noise on the Z switch wiring. To trouble shoot try moving the Z limit wires away from any other wires. You mite play around with the debounce controls in the General Config.

I think your pin number maybe incorrect. input pin can only be 10-13 and 15, the y is also wrong.

That should have been Reset not E-Stop

I have a similar problem, If I stop the program and maybe re-Zero the Z ,that the DRO will sometime run but no stepper movement. I have found if I cycle the E-stop after making a change and then restarting, have not had the problem.  I am using a parallel port. I am new so I maybe doing things that I should not be doing.

The pin numbers can be different.
You have a computer that is interfacing to your machine thru a parallel port, the parallel port normal go to a BOB (Break Out Board) I am guessing that you have at least 3 wires from there that goes to each drive assy for each stepper motor.
The 3 wires would be.
One is the Direction
another is Step
and Enable.
You need a wiring diagram to figure out what parallel port number pin goes where.
If you don't have a wiring diagram you will have to trace it out, and hope a connector is label to tell which is which.

I hope I get this right.
You need 3 signal per stepper motor from the computer.
Direction, Step, and Enable.
Step and Dir are set in the Config, port and pins, Motor outputs.
set for X Axis, Y Axis, and Z Axis.
Enable is set in the Config, port and pins, Output Signals.
Set Enable 1 for X axis port and pin number.
Set Enable 2 for Y axis port and pin number.
Set Enable 3 for Z axis port and pin number.
I do not think you need any input signal to get the motor to run.

I just went thru this myself.
mach3 pre-purchase will work, just limited to 500 line of code.
Someone will ask that you post Mach3Mill.xlm file so they can see what you have config.

What I over looked was the output signals. There are 3 enable signal that have to be set. It is the 3rd tab over from the motor outputs.

Are the motor readout display number moving on the main screen when you try to move?

I am new to this, but once I found all the little boxes to check it work great.

I am new so bear with me if I don't know what I am talking about.
Have you seen the automated setup of inputs?
Config  -  Ports and pins  -  inputs and pins tab  -  there is a automated setup of inputs button under the chart.
