Re: [CAD_CAM_EDM_DRO] spindle start and stop

Hi Terry,

It is possible and simple to control on and off using a relay but at 3.3
amp. there will be a lot of burning of the contact points therefore wear
will be a problem. A better solution would be a triac circuit. I'm sure I
have one somewhere if you want it.

Regards,

Terry
