G'day Guy's,
O'well back to the drawing board on the Z-axis as the stepper is toast. I used my stepper tester circuit to make sure I had the wiring right. Tested another controller still no go. Tested another another power supply, still no go. Tried a direct power supply and got the smoke. Anyway that stepper was out of an old printer and my single stepper circuit did do it but looks like I'll have to replace with a 5 volt 1 amp bi polar stepper I have here. so a new circuit will need to be made to suit the bipolar and I do have a few chips here to do it.

Cheers Bryan
