The relevant leds are on , on the BOB, my ports and pins are set correctly( they stop the M/C when triggered). but they only trigger briefly on the diagnostic tab. how are yours set up?

Mine are working like yours as Dean has said it will work different to the manual.
.
Regarding the homing you can adjust the racking by adjusting one of the homing switches until it is correct. X and A will back off the switches independently, it is hard to see when the gantry is square. But if you want to see it happen remove the belts (if you are using them and the are not direct drive) and put a maker tape on each motor pulley and then home the x axis if you then trip one switch the motor will reverse and stop when you release it. The same will happen to the other side. ..Clive

spot on , CLIVE /JAZZ, i spent a good bit of time initially setting up both switches square so it does look like it's not happening. i must try taking off the belts and using tape as suggested. good one .

i have 2M of 22 awg screened 4 core that i had set aside for the VFD control signals between BOB and VFD, This is the equivalent of 0.3 squared . i just read the VFD manual and it reccommends 0.5 squared . i can't get 0.5 squared locally . i'm about to give the 22 awg a try but would like to know what would the experienced heads use or have used?

For the control cable this will be fine. ..Clive

i'm in a spot of bother with the mach3 spindle control. i have wire the BOBto VFD as follows,i have set up the various ports, pins ,outputs as follows, when i turn on m/c the spindle starts up and i can't turn it off until i do a reset from mach3. i can then go to the output signals tab and turn on active low for output 16 and the spindle will turn on. i can toggle it on and off from this tab. i have tried to set the various related ports and pins, on/off, but i still get no joy. any help would, at this stage be appreciated
