Re: Unusual stepper ratings - vref settings for new Melzi

Thanks - so yeah, these are a high load then and not ideal from what you've said. It's an unwelcome cost for sure but I'd rather have it correct and help ensure longevity of the board.

The ones my friends both have on their machines are 2.8v 1.68amps, and 1.65ohms.

The Zs are actually in parallel as I've found that to work well in the past. I have removed one as a test though and the remaining one behaves just the same.

I've ordered 5 new steppers anyway at an identical spec to the ones they have in their machines, so I'll report back once I have them.
