Hey guys,

I've run out of inputs for my Parallel Port break out board. 3 axis with 2 motors and sensors on one axis (4 inputs), E-Stop and I'm out. I only want one more for tool touch off sensor. Easiest thing I can think of is adding another parallel port and break out board which will give me plenty but I'm wondering if anyone has an idea just to get a cheap extra one input?

Should add, I'm more than happy with the performance of the Parallel port. Just lacking an input. The break out board is super cheap for what it does too.

Happy Days.
