Re: [CAD_CAM_EDM_DRO] BP retrofit yaxis drive burnup- follow-up

Hi
Be sure to let us know how it holds up later , I chickened out and
replaced my motor and the burnt out Gecko hoping that it was the motor
that has been burning out my 201s . The scary part is there is no way to
know and the drives get expensive .
I have been running it for 2 days with no problem but in the past it has
taken several months for it to blow .
