On the one hand that results out of the discussion here (There you also can see some pictures, what I’m breeding here).
On the other hand that will result in a much stiffer cable whip, not hanging loose. I already had cable breakage because of bending the cable whip in another printer. Since I replaced the ribbon cables with round cables, the movement of the cable whip looks much smoother with wider radii and better distributed torsion along the whole length.
To be honest, the latter issue is more important to me and the first came up as a by-product just using shielded cables after the decision for round cable was already made.
I decided to use two cable types:
- for SPI bus: Cat5e 4 pair AWG 26 (flexible)
- for Stepper and Fans: LIYCY TP 2 x 2 x 0.25 mm² (flexible)
I have that. You think about inductive coils? And yes, the cable shields get connected to Protective Earth (PE) - on one side only.
