 Everything seems to be sorted now. Engraving text OK,  ie I don't have to stand on my head anymore.
Thanks for all your help Tweakie.

Note :- Must now make a note of my setting for when the computer goes belly up again.

Things are now looking reasonable having having calibrated the axeses and got control of the spindle.
Used 'write' to engrave some text. It looked fine on screen but when cut was backwards and upside down.
It will save me time if anyone can say what I have done wrong.

Tweakie.
Before reading your latest mail I found a record of how I had set up mach3 originally in 2007 and noted some differences from my current settings.
I put in the 2007 settings and everything worked!.
The main difference was that the motor output step and direction pins were in the wrong columns ( if I make myself clear).
 spindle was selected - step pin = 1, dir. = 17, tick, tick 1,1

input signal used was - timing enabled -  port 1, pin 15, tick, X, 0

output signals used - enable#1 - tick, 1, 14, tick
                               output#1 - tick, 1, 16, tick

Testing the system the spindle reacted to M3,M4,M5 as it should but the spindle started to turn only when a speed of 3600 or higher was requested.
So I messed about and succeeded in stopping the spindle rotating with M3!!!, still OK with M4. Do not know what I altered but the red LED on spindle electronics permanently ON.
With M4 the red LED flashes in tune with speed of rotation.
Further work required to solve this one. NOTE record all changes made in future.
At least it is not a faulty computer, just an embarrassed operator.

Tweakie,
Dashed straight out and disabled the outputs and got no movement at all!!!.
Re-established the outputs and was back to being able to drive axises in one direction only.
Thoughts:- re-install Mach3. Look inside computer for damaged mother board which could have resulted from flat battery. Anything else?

Tweakie,
Things not quite as easy as expected. I have two profiles and hence two 'xml' files in Mach3 directory. However I found by checking dates that the newest files had no extension
 which threw me somewhat, the old ones had the xml extension. On copying the new files to a USB stick they acquired the missing extension?!.
Checked mill action using the new file and it was just as before; X,Y,Z axes moving in one direction only.

Well Tweakie I cannot understand this.
If I look at ports and pins on the computer that is not what I see. The entries under step and direction are 3,5,7 and 2,4,6 and pin 17 for the spindle???

I have just copied this file from the computer having first verified that it does drive the three
axis's in one direction only.
I have named the file Thomas.xml after posting problems

Yes tweakie I cannot make any sense of the voltages either and I am sure the pin allocation is correct. Incidentally pin 1 gave 4.1v, the highest reading on the port.
I think it is time to take the lid off and have a look. Oddly my spare XP machine gives similar readings; any chance of the port driver being corrupt.
I have now got a copy of W2000 and may try that on my spare M/c.
I am attaching my xml as requested.

Tweakie, thanks for you sticking with me. I will post my xml file tomorrow when I go into the shop. I have changed the pin settings so often I cannot remember where I started.
Today I checked the P/port output pin voltages  again while pressing the axis direction keys on the jogging 'fly-out'.

Pin 2 - Pressing X- gave 2.37v,    X+ gave 3.32v
Pin 4 -   "          Y-    "   3.07v     Y+    "   3.32v
Pin 6 -    "         Z-    "   3.06v     Z+    "   3.32v
These readings reversed if motor output set to Dir low Inactive but the voltages remained the same.
Two things strike me; very little change in the voltages and how did it work before under W2000.
Could I have an electrical problem on the mother board. By the way at start-up it states the driver is initialised.

Found time to look at the jog button and I try my jogging tests with it active.
That does not appear to be the problem or the solution.
I find I can jog in one direction with each axis, say X+,Y+ Z+ using the buttons on the MPG Mode 'fly out'.
The minus direction buttons produce no movement. These two states can be reversed by checking active low, but no how can I get any
axis to drive + and - using the buttons.
I feel sure it is a port and pins problem but what needs altering or should work with the X,Y,Z axis's.
