Need helpwiring up from scratch

[irving2008]

you have to tell it what steps/mm and acceleration.. just use 100 steps/mm, velocity 1000mm/min, acc 5mm/s/s, step pulse 5, dir pulse 5, these are good defaults for now... you'll set them correctly once the machine is built.

The charge pump LED should be out (I think) until MACH3 starts then it should come on... or the other way round... either way it should change...

The power supply LED glows when it plugged into the parallel port but not powered? hmmm, then its being driven from the parallel port outputs which is possible through the input clamp diode on the buffer chip so not sure that in itself is an indicator of faultiness...

I have a bit of software to exercise the parallel port, to prove hardware independent of MACH3... i'll try and upload it later on today...

Taking the stepx(-pulse)to ground steps the motor incremently each touch to ground,Irving.
