Re: [CAD_CAM_EDM_DRO] Re: Question on Mariss' E-Stop circuit

I'm running large servos and using a 5 to 10 adjustable resistor set to 7 ohms and it works good. If his plan said to use 2.8 ohms thats probably what it needs.

Another thought, according to Mariss' instructions I would use a 2.8
ohm resistor on my 28vdc power supply. That would dump faster than
the 7, right? Or would a 7 ohm be fast enough? I did a quick look at
RS tonight, nothing there in 20 watt power resistors.
