Heatsinks

[DrLuigi]

Nothing wrong with some extra precaution but if your steppers are running that hot then you need to go into your firmware and turn the current down. I can run my printer all day long and the steppers are barely warm. The extruder is a bit warmer but you could never burn yourself on it. I have no heat sinks or fans on them at all. The printer is metal so there is some heat transfer there im sure.

Nah ramps uses a POT meter, you cant do it within the firmware,
The voltages are pretty accurate when i last adjusted em a month ago.

Well mine could burn you if its been printing for about a hour.
But only if you keep your finger on it for a minute or so i guess, it would hurt anyhow, never tryed to burn myself

Well most people that have a 3D printer from makerfarm report hot steppers.

You could make your own sinks from copper pipe caps or tubing, or aluminum.
Just JB Weld them on.

Anything copper or aluminum to add more thermal mass and area to it.
