Based on the published specs, he's right where he should be. 1.7 amps * 8 * .05 ohms = .68 volts. The question then becomes are the drivers and motors actually to spec. I'd double check the sense resistor to make sure that they are actually .05 ohms. Official Pololus have a .05 ohm sense resistor, which is what the linked to specification states as well. However the image shows StepStick, which the "official" version called for a .2 ohm resistor. With open designs and knockoffs that say they are official, it could be anything...I had some drivers that came with .3 ohm resistor which threw me for a loop until I discovered that variance from the norm.Quote

turn up the current on the drivers..... your motor doesnt seem to be getting enough current...
