Hi Malcolm,

That .xml does have ports and pins configured, however, as mentioned in my earlier post (#24) You can't use Port1 Pins 2, 4, 6 for Output Signals when they are already being used for Motor Outputs.
If you disable Output#1, Output#2, Output#3 then your axes will most likely drive in either direction.

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?

Hi Malcolm,

Something else to try...

Disable the Outputs# (as previously mentioned).
Change Step Low Active (to a tick) for the X, Y, Z axes in Motor Outputs.
Change Step Pulse & Dir Pulse from 5uS to 2uS in Motor Tuning.

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.

Hi Malcolm,
computers are especially good at making people look like plonkers, and just to think its only going to get worse. Good luck.

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.

Hi,
I thought you were supposed to be 'arse about face and on your head'...lol

Probably the most common configuration is XY 0,0 is with the tool at the extreme left hand side of the table and the
table at its furtherest away from you, ie the 'lower left hand corner'. Note this may not be the machine co-ordinate 0,0
but your work co-ords. As the table moves left X increases from 0 and as the table moves toward you Y increases from 0.

I remember it as the same orientation and direction as an X Y Cartesian graph that we were all taught at school.
The active point is the tool tip.

You can reverse directions by checking/unchecking active low on your direction pins. It pays however to keep in mind
the 'standard' orientation if you ever get given some code to cut or if you wish to post your own code.

To complement Craig's description, the Right Hand Rule drawing shows the tool movement in relation to the work-piece.

 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.
