Yes but it would seem to be easier to change from 50 holes to 1 than to design circuit, buy parts, assemble board, program board.

well £24 delivered isnt bad...
blanking out 49 holes might not be as easy as you think, you might need to provide an alternate sensor. Also if you do blank the holes you'd prevent using it for closed loop speed control later...
I liked the look of it, its fit for purpose and the price is not bad, although im not sure if i will end up buying another sensor, it will be interesting to see what that chip is on the back.
As always im thinking you are correct, maybe ill just mount another sensor on the spindle and be done with that, mind you i couldnt find anything suitable on fleabay

This may sound stupid, but im just wiring up the drivers to the BOB and i was wondering if there were default ports used for axis, IE X=pin??? y=pin??? etc.. I do like to keep things default, as it makes things less complicated If I get problems.
yes there are...

Hmmmm.... childs putty will do nicely methinksQuote:

Hey Rick,can you pop some putty in two holes of those holes when you get the machine up and running....if the putty flies out I will buy Irving 2 pints a day for the next 12 months.
Push it in the holes and cut off the excess both sides of the holes.
Hey Irving, thanks for the pinouts, thats made life a little simpler, i notice that there is only 1 pin for spindle output pulse, on my board from cncdoctor there are two,one terminal labled "Pulse" and one "RTN"...
Also Ive been looking for a sensor for this display i found on fleabay with no luck, do you have any suggestions?
