Help with drill-Mill conversion

**Ross77** · 08-08-2009

Thanks Irving thats exactly what I was looking for.

For this board I'm going direct to the driver chip but it will be useful to have the opto verision as well if you dont mind. Is it posible to do single steps with this circuit as well :whistling:.

Thanks again

Peter, seems to be ok when I look at it, dir pin is linked to the resistors

Here is the opto version...

Single steps I need to think about (and why would you want them?)

Another fine point of MS IE7 I expect!

Thanks Irving, your a star. have a couple of beers

The single steps are for fine tuning, I'm planning ahead really. Once it has built the machine I want, this mill will probably be redundant and not worth selling, so I thought that It might be useful if I just need a part skimmed or holes drilled at set distances. If I also fit a DRO of some discription I can manually control the machine as a stand alone without having to draw the part and produce g-code etc. etc.
