Frequent problem with step motor driver failure #34

Open rcoscali opened 5 years ago

rcoscali commented 5 years ago

In a short period of time I had two failure of step motor drivers (A4988) circuits. First with Y axis and second with E. I found no other solution than changing the board. Is this a known problem ? Is there something I failed to do to avoid such failures ? Measures with oscilloscope shows no current on the failing driver capacity (c17 for Y) and didn't yet measure it but wwill do shortly, I expect c25 current to be null. Can you help about it ? Thanks

Is your motor current set correctly? If it is not, it will quickly burn them out.

@rcoscali is this ongoing or did you find a resolution? Are we clear to close this old issue?
