Got my new Melzi board today.
I've hooked it up and very briefly tested it. Mostly appears to work except the LED on the board hasn't come on once for some reason. Bit odd but not the end of the world - not thoroughly tested it yet though.
Now I want to ensure everything is setup correctly before I try printing anything, but here's the thing. The steppers that came with this machine are rated at 0.4 amps even though I understand a typical Nema17 would be anything from 1-2 amps. So given they have a lower rating, I assume they're a bit weaker than normal ones, but also would need the Melzi's drivers setting to a lower output to avoid overheating them or damaging them?
Any idea what the vref should be set to then on account of the 0.4a rating that these steppers have?
Appreciate the help
Thanks :)
