Boxford 190vmc upgrade

Hi Jazz,

I have only re-visited the setup of my machine and last week I bought the full version of Mach4 which I now have setup. You stated in your last reply that I need to control the relay to switch polarity of motor. There is a relay on the original board for which if the direction and the 0v wires are connected it flicks the relay over and initialises reverse direction, it would be great if I could work out how to incorporate this switch within the 107. So I suppose my question is should I be using the original relay off the original CNC board or should I use the relay on the 107? If it's the relay on the 107 I dont understand which wire connects to which terminal on my power supply board (simplatron). Looking at the power supply board it does have 5v and 10v but no reverse option so I assume with my current setup the only way to get reverse is via the original relay unless I strip all this stuff out the machine. I attach a couple of photos, the one shows the original wiring the other shows my new wiring (temporary blue wires). Would be nice to hear your thoughts on this.



And reversing switch which works (when I join 0v and direction wires).
