Denford Mirac Electronics Refurbishment

Hi Guys, Sorry its been ages since I've last updated. I've been stuck twiddling my thumbs a little as I am constantly waiting for bits to turn up.

I wired up most the machine. I've managed to get both axis's working, the spindle turning and the tool post turning.

The Control card from CNC4PC is very limited in terms of inputs. I have had to purchase a further Parallel post card and breakoutboard to connect the home and limit switches to.

I'm struggling to get the spindle to turn at the desired speed. It seems to just stay to one constant speed even when using the mach3 tuning tool. I am also struggling to work out which core on the encoder goes to what, i.e are they pairs do they need 5V and Gnd etc

With regards to the tool post, that bit seems to be rather simple, all you need to do is tell mach3 to watch the grey code for the correct tool then stop and reverse then switch back over to the spindle. No voltage need to be applied once is fully locked in, though it wouldn't be possible to apply any constantly anyway as you can only have either the tool post on or the spindle on at any one time.

Oh and does anyone know how many steps per inch or whatever it is?

One final thing, any CAM recommendations?
