Initial impressions

Just opened the package up, and am very pleasantly surprised at the solid feel and how nicely this is built. I ordered 3 of sainsmart's 101=60=194 stepper drivers, and will soon be testing it out. I have to do a bit of checking the motor phases, and some miscellaneous parts gathering etc but will be ready to roll shortly. My guess is to rally up a power supply, and get all of the motor leads rung out ( ohmed out to verify I know where the coils are )and wired to the controllers. Then setting the max amp rating of the motors on the dip switches located on the driver boards I think it is 1.5 amps, but will have to double check... Then to test the strength of this baby! Tally Ho!
