What triggers z to move in a differant direction. For instance I made up a short code as follows:

G0 Z5.0000
Z0.0000
Z5.0000
Z0.0000
In every instance it would change directions and move 0.001 and stop. If I stop the program, then click reset and click run, it runs that step. Next direction change is the same process.

After a thought I was grabbing at straws with Manual. What I did was change spindle control to manual

When I changed the pins around the problem transfurs to pin 2 and pin 6 works well.I don't know what that means but it is defiantly in Z

Where do I do this swap?  In Manual Z still works in only one direction. As Z10.000 it moves fine but Z0.000 it moves to 9.9999 and the DRO stops but the maching keeps going.

Do you mean use Pin 2 instead of pin 6 and use X to move it? I will put the machine on manual and see if z works there

I coded g0  z15.000 so I could get a good look and did this several times. 039.4 stopped and 149.4 running and then stopped returns to 039.4. So that looked good but then I coded g0 z0.0000 and it moved 0.001 an stopped on the DRO and I got 061.4 MV, ,  Stop it an re code it and it would run, It doesn't change direction with out using the code twice

I reset the E stop as instructed. Checked pins and no result. Thinking I might need the mirror image, changed pins and its amazing what you get when its right. Guess that's why I was a millwrite.  Stop reading is 039.3 and running is 149.1 with a slight bounce to 149.2 but it remains pretty steady. I took this 3 times an came up with the same answer. I see no pulse.

After some thought it is possible I am reading the wrong pins. I am off tomorrow and can work with this then. If the diagram that I have used of the PP end is female then I need the mirror image of what I am testing. I will reset E-Stop and start over. . Thanks for your help and patience

The only place I see a E-stop mentioned is in ports and pins, Input signals, scroll down to a box titled E-Stop and I unchecked this box turning it to red. It doesn't stay red and I don't see any other place to do any thing with E=Stop

Okay, I went to ports and pins, Pin set up and checked the box to enable port 1. Moved to Input signals, Found E stop  box and changed it, Clicked apply and okay. Rechecked and it had changed back. repeated steps half a doz times with the same result

I did take a reading anyway but no change except in G0 the reading is 0.6 MV instead of 0.4 of g1

As I see it and maybe I am wrong but Mach DRO is running. It just isn't turning the machine
