Dip switches set as OFF OFF ON ON OFF ON ON OFF , which sets the thing to 4.9A Peak, 3.5A RMS, Full Current from SW4 (i don,t really know how to set this), and 2000 pulse/rev. The next current setting is 5.7A peak.
This might be to high try sw 5,6,7,8 set to off/on/on/on = 800 p/rev set sw 4 to off = half current when idle

setting the above will alter the distance travelled but that can be sorted later when you get the motors working
