oh you mentioned about needing an external power supply, does that not come direct from the 2nd parallel port?

The pin numbers and cable colors are in the links I sent.

If you have two e-stops, they should be connected in series, so that any of the buttons can open the circuit an trigger e-stop (now you see why the C22 has a relay?).

A parallel port cannot source current for external devices, you need an external power supply. You could draw power from the USB port.

I still cant get the MPG pendant to work and its driving me absolutely mad.

I initially thought it was the LPT2 address and it turned out I did indeed have it wrong, so reset it to 0xECF8 in mach3. As far as I know the port works fine, I can use a printer from LPT2 no problem.

I wired the pendant into a 25 pin connector as per the cnc4pc document so:

red and orange/black were connected to USB + 5v
black and white/black were connected to USB ground
green to pin2
white to pin3
yellow to pin4
yellow/black to pin5
brown to pin6
nothing to pin7
grey to pin8
grey/black to pin9
orange to pin10

the e-stop blue and blue/black were left disconnected for now until I can get it working and I dont think I need pink, pink/black, red/black and brown/black. I am fairly sure what I have done so far is wired correct. There is still a bare non coloured wire which has solder on the end and not sure what that is?

I have followed cnc4pc`s instructions manual for settings and loading the brains etc and when I plug it in the led light comes on but absolutely nothing happens.

In diagnostics the output 6 light is on.

What tests can I do to start eliminating things and hopefully reduce the hair pulling and get it sorted?
