Topic: Floppy disk power connector for hot end?

I've been reading about installing an E3D and various recommendations for connectors to hook up the thermistor and heater. I've got a near infinite number of random computer cables, and it occurs to me that some of the floppy disk power adapters have the 4 connectors I'd need. Anyone think they are big enough to handle the power required for an E3D heater?

Or if not floppy, the old style molex computer power connectors would certainly be big enough, wouldn't they? (I've got even more of them than I do the small floppy connectors :-).

Re: Floppy disk power connector for hot end?

I'm about to go on this venture myself.  I spliced almost all my wiring to my rumba board, so now it's partially a rats nest.   I want to go with as clean a cable job as i can.

Computer wiring should be a good route, they are coming out with all kinds of nice solutions for cable management in desktops.

Yup, they can definitely handle the current.

What about the hotend fan though?

I assume the fans already have standard fan connectors on them (though I'm not sure how long all the cables are).

I have in the past used another thing I have in excess: spare USB cables.  I make a long fan cord by splicing together red and green for
one wire and black and white for the other :-).

Nope, no connector. Not to mention even if there was one, you'd probably want one at the hotend so you don't have to pull cables through the loom to switch hotends.

I'm a fan on the wire-through-to-the-board method, as changing the hot-end is something you basically don't have to do with an E3D... smile

Also that. Mine's set up wired all the way to the board. I just assumed if he was putting in connectors for heater/thermistor at the hotend, he'd want one for the fan.
