Recommened diameter wire?
-
Hi
Taking advantage of the fact that I am changing the Duet board ... I want to rewire some components (Zprobe, and Nozzle thermistor).
The distance its about 1 m .... what kind of wire (diameter) are recommened?
-
@peirof Neither of these components take any current, so some 30AWG silicone insulated wire would give you a very thin and very flexible way of connecting them.
It's what I use for sensors on the print head and it's easy to twist them if you clamp the ends in a vice and the other ends in a drill chuck. Just don't go too fast!
You just need to fold the wire twice or three times to make it thick enough for the crimp connectors to the Duet board.
-
Those parts connect to the board using the connectors supplied with the kit. 20 or 22 gauge stranded wire works well with them. I wouldn't go much bigger or smaller. If you go bigger, you'll have trouble getting it to fit in the connector shell. If you go smaller, the resistance of the wire may cause a shift in the temperature reading.
30 gauge wire is flexible, a few times, then it breaks because it is made of a single strand of copper. It usually has shellac insulation that is difficult to strip reliably.

I don't know where you get your 30 AWG silicone wire from, but mine is multi stranded and superbly reliable. I use it for control signals on multi rotor flying machines and it's never let me down.
I'd never suggest that someone uses single strand wire on any part of a 3D printer which is in constant motion. It will, of course, break in a very short time.

I recommend "BNTECHGO" silicone stranded wire on amazon. Excellent flexible wire. The 24 gauge 4 conductor is nice for steppers and such. (I have a whole collection now, from 14 gauge for power connections up through 24 for smaller load stuff)

Silicone wire is available in three types, one with Ø0.08mm strands, Ø0.12mm strands and single strand; with the Ø0.08mm being the common one in RC use and is super flexible.
-
Yep, the BNTECHGO brand has 0.08mm stranded wire. Great stuff. (really reminds me of the "Wet Noodle" cable from RC)
-
@kraegar Thank you for recommending, I bought Ultraflexible 60 strands, they are great.

60 * 0.08mm = 22 AWG @peirof
