Ok thats the rubbish yanked out!!
:cry:
Thats the progress to date, New stuff arriving any day now. The speed controller and the rack with the drivers in it have only been removed temporarily while I get the wiring sorted and to allow me to mount the new breakout board when it arrives..
Now comes the bit i hate....WAITING FOR THE POSTMAN!!!!!!!

After 28yrs of marriage i suspect she has learned to keep here opinions to herself and im not going to ask how she feels about it, she benifits from the bikes i do so i suppose she can see the logic but again ive learned the hard way if you dont ask for someones opinion you are less likely to be offended by it!!! (besides ive seen her watching with interest over my shoulder when im watching the cnc stuff on Youtube!!!)

Ive started to design the control panel to replace the old tatty one ive taken off and it occured to me that i would like a tacho on for the spindle, after spending a couple of hours searching the net i came up with the Trexon Tachulator from MKC Tools however they are on a summer break so thats a no go besides which coming from america it takes an age, so back to the drawing board.. So im not trying to re-invent the wheel here i just want to buy a board similar to the Trexon.. but guess what i just cant seem to find one so any sugestions here?

lots of ways to do that.... what do you have to monitor the spindle speed? an index pulse or just a control voltage?

Yes. with that number of holes was probably used for closed loop spindle speed control rather than just speed measuring. Have you retained the spindle speed controller and do you plan to reuse it? Even at this age it would have been 0 - 8v or 0 - 10v control signal and MACH3 can drive that through a suitable speed interface and that might be a lot easier than finding a suitable replacement speed controller. Any idea what the max spindle speed might be?
Thanks for that in-depth insight...
