Hello everyone,
From what I understand now, after reading more carefully sanguinololu wiki, it says it' s not recommended to use high voltage Nema 17 motors. Unfortunately I bought 5 of them. These ones: [www.ebay.co.uk]
Because it said perfect for REP-RAP. Next time I'll be more careful.
As far as I understand my current limit should be 0.4A *0.7 = 0.28A? And the Vref voltage 0.112V from the equation.
Mostly my motors work just fine, like for X and Y axis. But for Z axis, they barely turn. If I understood correctly I doubled the current limit, since Z axis has two motors. basically for Z axis 50 mm in software translates to about 10mm in real life. I suspect it' s because of my motor choice. Is there any chance fixing this problem, without replacing motors? Any suggestions welcome.
Kind Regards
Raivis
