Re: Going home / more stepper speed!

Alan,

"Modified" half stepping increases the current on the "one phase"
positions. Pretty simple to implement, and 1/2 step is MUCH better
for adding it. Boost single phase to 1.414 or reduce "two phase"
to .707 by adjusting the ref volts to the chopper.

Scope traces can be seen in most stepper app handbooks...

Hope this helps.
