RE: [CAD_CAM_EDM_DRO] Re: Power Supply for Gecko 320 and servo motors for 3 axis router

Hi Gregory,

What type of machine are you running them on? When you de-accelerate an axis
the motor produces voltage back into the power supply, know as back EMF. A
DC motor whether servo on not is a generator when being turned by the load.
A switching supply will not like it when voltage is back induced into its
output. Makes smoke in most cases! (:/
