I am running an L297/L298 driver board with 2 PC power supplies(24V) and using the Automation Direct motors (276 OZ-IN, NEMA 23, BIPOLAR, 2.8A/phase, 1.1ohm). I had been working with it for about 5 minutes trying to figure out why it would run along just fine and then stall for no reason when all of a sudden I heard a loud pop(at first it sounded like it came from one of the motors) then I saw the smoke coming from my "Y"axis driver (L298). I'm sure my combination of parts is not the best match but have put two things together that just don't work or is this just a heat problem? After it popped I could touch the heatsink but it was hot
Thanks for any help
