Hi,
don't go changing OS, I don't think that's the problem.

I need screenshots of your ports and pins pages, at the least motors,inputs and outputs tabs. Screenshot of general config page
would help.
Need a copy of the manual for your BOB and/or drivers.

Craig.
I will need a little time to pull this together, I built the outfit in 2007 so not exactly fresh in my memory.
I don't recall getting a manual the BOB/driver board which came ready assembled.
The only identification on the board or case is a 'made in the USA' sticker and 'version4' on the CB.
The unit was bought from a firm in Glasgow, Scotland. I will look to see if I can find any paperwork.
Meanwhile I have photp'd the board and will see if I can send a copy.
The spindle rotates but with no control but not concerned with that at the moment.
I will see what I can do re ports & pins.

You can't use Port1 Pins 2, 4, 6 for Output Signals when they are already used for Motor Outputs.  ;)

 Tweakie,
First thing to say is I changed my CNC computer for a spare I have which was also running XP. No difference in control so I conclude the problem lies elsewhere.
Using your figures/instructions I set up the spindle pins which had not been my priority earlier. Obtained immediate control of the spindle speed and direction, great!!.
 Noted that spindle speed does need setting up. Secondly no speed displayed in the DRO. Played about for s few minutes then Crash?? spindle stopped dead.
Opening up the covers revealed that the index plate had come loose and working up the shaft had jammed the shaft. Re-secured it but every thing dead, further examination
revealed a blown 5amp fuse. Replaced, and we had lift off with the spindle.
However neither X,Y, nor Z axis would move at all, not even in a singe direction as I had yesterday. Another blown fuse??. There is power to the driver control box, (red light ON).
Where from here??

Have you turned the Jog ON/OFF button to OFF ?

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.
