Hi Guys,
Does anyone have any info on some basic testing I can do to these Stepper Drivers? I need to know if they are faulty or not.
I don't have a equivalent driver to compare to.
Stuff like current draw at idle, etc.
I assume a schematic drawing is not avaialble.
I opened up 2 of my drivers and both had approx 9 dry solder joins on the output chips!
They look like it was 'factory' soldering as I could not see any heat damage.

Steve
