I've been looking for a dip switch configuration chart to work with the pre-2010 drivers for a while. Syil Canada was able to help me out with the numbers so I thought I'd put it in a chart form on this site....
S1 is for the half current setting (enable = off, disable = on)
S2-4 are for setting of the micro-stepping
I realized that the formatting of what I posted was terrible, so I cleaned it up and put the info into an excel file.
