Exactly why I *was* okay with them blowing up, but originally asked to =20 see if there was any way to reduce potential damage. Now though, I =20 am concerned with the one report of a resistor violently blowing up. =20 The automated workcell was built for multiple purposes and we thought =20 we could make a 3D printer out of it too with the addition of an =20 extruder head. This is just for the fun of it and I really don't need =20 it for anything useful, sensitive to downtime =3D almost zero. Cheers, -Neil. Quoting David VanHorn : > Is it really worth all this sweat?
