It rather depends on if you run out of computer speed or motor speed first. If you can easily drive the motors faster than they can move the machine, then more microsteps can give you a bit more resolution and possibly a bit more performance (smoother stepping is better for top speed.

Do you definitely have the motors correctly wired? If the motors only have 4 wires it is pretty straightforward, but with 8-wire motors it is possible to have one phase wired back-to-back so that is is totally ineffective. -- atp ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
