I recently got ripped off by taking remote delivery of a cute little Sherline CNC retrofit. The seller (who I never met) was supposed to provide docs etc but just took my money. I got the mill working but just blew it up a little tying to straighten out the wiring mess that would have blown up on its own if i didn't do it first. I have no idea who made the 4 axis bipolar stepper driver board. it seems to be a chopper and maybe microstepping. my guess is that it is 10 to 15 years old???i need to identify it so i can figure out a few switch lines. some lines were jumped together and i accidentally lost track of which ones were. there is no identification on the silk screen or the copper on either side of the board.

It could be a Xylotex.
The picture looks very similar except for the fuse(?) by the power plug.

thanks for the speedy reply. the four axis version is what i have. the only difference is the cap (not a fuse) where something else is in the current doc. with your identification i was able to determine that nothing is wrong with the board. the wires i accidentally cut were not needed anyway as they were just redundant common leads for the step and dire signals. the guy who set this thing up was a moron and a slob. i accidentally fried something trying to figure out all the same color leads and sloppy soldering. now i can concentrate on what is probably the problem, a burned out buffer chip on the breakout board or maybe the parallel port on the computer.:cheers:
