my big easy driver recently stopped working. When i measure the signal on the motor outputs i just get the same voltage as the powersupply (5V) even though i have the stepper and direction as well as ground inputs connected.
shouldnt i get some rectangular signal from the motor outputs?
Now the outputs A,A',B,B' are all 5V if powersupply is turned on and 0V if turned of. Is this a sign of a burnt chip`?
No public wish lists :(
