Hi,
do you have a multimeter? Disconnect all wires from your BoB except the power supply wires.
Suggest: Config/Ports and Pins/Input Signals scan down to Estop, check Enable, Port=1, Pin=10, click Apply.
On Mach3 Diagnostics Tab is the Estop LED active or not? With your multimeter measure the voltage of pin 10 of your BoB
relative to 0V. If the voltage is high, 5V for a 5V BoB then your BoB has a pull-up resistor. In Machs default configuration, Estop
is active high, then I would expect the diagnostic Estop LED to be ON. If the voltage is low, 0V, then your BoB has a pull-down
resistor and I would expect the diagnostic Estop LED to be OFF.
Now: Config/Ports and Pins/Input Signals/Estop Enable=checked Port=1 Pin=10 Active Low=checked, Click Apply, I would expect with pin 10
voltage high then diagnostic Estop LED to be OFF. With Estop OFF you should be able to Reset Mach and have the Reset button go green and
be continuously light. If however pin 10 voltage is low, ie pull-down resistor, the diagnostic Estop LED should be ON. With Estop LED ON
no matter how hard you try you will not be able to Reset Mach, nor will you until you clear the emergency fault and get the Estop LED
to turn OFF.
If you now take a small wire from pin 10 to 0V, or alternately to 5V you should see the diagnostic Estop LED change state.
If you can follow this and get the Estop to work you've learnt about you BoB, that is, a pull-up or pull-down resistor and you've established
that your BoB can communicate over the parallel port. Thats good progress.
Let us know how you get on.
