C3 index pulse board with three optical switches in series...
« on: August 13, 2013, 01:57:41 PM »
Hey all, I wonder if someone can help me. 

I thought I would be cheeky when setting up my optical slot homing switches on my sx3 and use them connected in series to cnc4pc's C3 index pulse board as I had this wired up already from the lathe set-up.  I was able to get two up and running but whenever I connected the third in series it wouldn't work.  Now, I am not up to date with electronics so unless it's obvious im at a loss.  Any ideas?  I'd rather not have to buy another interface board unless it was cheaply priced.   

Thanks, Rob.
