stepper motors loose steps when cold
« on: May 05, 2007, 09:58:41 PM »
my 1200 oz in stepper motors don't run worth a damn when I first turn them on.  They loose steps all over the place.  I'm running mach 3 mill, gecko 201's. After I run them for a while, same speed they run just fine.  Anyone have any ideas.  Any thoughts would be most appreciated.  Thanks Cleveis

That is odd... try changing the active low state of the step pulse and make the step pulse a bit bigger...

That is the first test ;)
