Converting a 1986 Triac to Mach 3

Post by Roy » Sun 26 Oct , 2008 12:20 pm

I am in the process of converting my 1986 Triac PNC3 to Mach 3.
So far with thanks to some tips from 'sweep' and the drive interface diagram provided on here by David Murray I have managed to get all three axis moving via Mach 3. :D

Now I decided to buy a C11 breakout board (cnc4pc) to protect the pc, charge pump function and hopefully take care of the spindle and datums etc.
So far i have this wired up to the drives via the interface board. The breakout board requires an additional 5v dc at 1.5/ 2 amps. At the moment i have just hooked up a seperate power supply for this, but I want to run this from the triac power supply.

I am no electronics whizz, so now my question!!(s)
Where do i get the 5v from on the Triac??

Do I also need to keep the main triac board to use as the power converter/distribution. Ideally i would like to take it out, but if it is easier to use it 'as is' just for the power then i will. Obviously I can unplug all external wires which i would no longer require, vdu, front panel etc etc.

Thanks in advance, Roy
