Motion Control drivers and motors

Maybe you should strip everything back and set one up at a time and see if you can find the problem that way, i noticed kip said somthing about your SW's being set wrong on the other post.

I'v just merged this thread with the other one you started Bruce as they see to be about the same thing, be nice to see a new thread on the conversion of your mill after you hash these issues out.

I'll be doing a full write up of my entire set-up once things start working fine because I'm sure that are many like me who are complete novices and everything out there assumes you know something of CNC, plus there are very few UK only people who have a full write-up.

I was a bit too over confident and set-up everything into the box. If with the new BOB things don't start to work well then I'll have no other option but to start again.

Gary has already suggested its an issue with low power laptops didnt he?

I just had an email from Bruce, and it apears that his clock pulse is about 3.3V, and he is using a laptop.

This is most definately the problems, and is actually quite common when a laptop is used.

The solution would be to use either another laptop with higher voltage outputs, or a desktop PC with a parallel port.

Bruce,

Try this and give us your results.
Thanks
Gary
