[HELP] 6 Axis B.O.B with spindle control

[cropwell]

My simplistic brain understands it thus :- Mach3 or other control software puts out a signal that says it is operating. That signal 'pumps up' a capacitor on the BOB. when that capacitor reaches a certain voltage it enables the circuits, so motors will move, relays will click and spindles will spin. Others may offer a more technical explanation, but my mind can't cope with too much. .
.
I never got it working on the BOB, probably because it was never set up properly on the output pinout in Mach3. The company in Devon that I got the machine from sent me an xml file (Mach3 parameters) and I just used that, when the charge pump didn't work, in retrospect it appears they didn't have a clue why. So it was disabled on the BOB and left at that. At the moment I have not got the machine computer connected up, so I can't look into how it was set up (or not, as the case may be) in Mach3. I will bet that it wasn't enabled !!!

I currently have a PCPPS breakout board from http://www.diycnc.co.uk which has a charge pump (works OK with LinuxCNC) but it is NOT opto-isolated and doesn't have a spindle control. The above website can supply a separate spindle control board at a cost of £25 - £30, so total cost is around £45 for a B.O.B. and spindle controller.So http://www.ebay.co.uk/itm/251652222037 (as suggested above) seems like a good alternative. At half the price, I can afford to buy 2 and keep one as a backup for replacement or another project.Anyone using the above board in their project? Reliable?
