Hope someone can help here....

Wiring up the MPG I bought, I have installed a BOB (one of Gary's) which is a very simple (no opto-isolation etc.) type.

I have set Mach3 and my Smoothstepper to look for a second port and set them both to take pins 2-9 on port 2 as inputs for the axis selection and step multiplier. It looks from a little bit of research, that I may need a 10K resistor wired like so to get Mach to read pins 2-9 as inputs. My question is what type of resistor should I buy?

On Ebay I see carbon film, mtal film, carbon composite and so on, is one type more suitable for my use?

Thanks for any advice.

Jeff.
