The right voltage for my Stepper Motors in order not to lose steps

[jhonansaro]

Hi Neale and m_C

Thanks a lot for your valuable comments.
m_c : as matter of fact it is almost off always in same direction. Could you please explain How can I check
for my step/direction signal timing?

also Neale could you tell me how can I check for my correct step signal polarity?
I will also try that air cutting that you mentioned
