Motion Control drivers and motors

OK going to try and get my hand on a 'full' PC and see how things go.

Does anyone know of a supplier for a buffered Breakout Board similar to the ones CNC4PC do but in the UK? Hopefully that will give me a full 5V signal and I can use my laptops again.

Bruce - how are your drivers wired to the PC? The MDS series are opto-isolated. Unless there is some strange wiring issue a higher output voltage wont make any difference as they are active low drive.

I'm going to give Gary the benefit of the doubt here because he obviously knows his products better than I. So I've bought the only CNC4PC C1G breakboard board that was in stock. Hopefully this will solve my problem. If not then I'm back to the drawing board. Having said that the MSD542 manual does says that its looking for 4-5V for Active High and 0-0.5V for Active Low and since my laptop is giving 3.33V it may not be enought to kick the driver properly
