Re: [CAD_CAM_EDM_DRO] Re: Maximum stepper speed

I was wondering if the heat limit was reached before or
after the insulation limit. Maybe i just need to look at
some specific data sheets more closely. If high speed
operation is only occaisonal on the machine, then i
can get away without heating problems.
