Which Crimpers for Duet 2

Soldering is technically better, for small wires:-

That conference in your link seems to be talking about crimp connectors that were faulty because they were made out of the wrong material.

The connector representing the 2005 (good) lot showed
excellent bonding along the pin-crimp sleeve interface.

It does mention that soldering to solder lugs is better than crimping a pin improperly. It doesn't mention soldering a crimped connection.

I'm just trying to learn. I'm not an engineer. I don't work in aerospace or nuclear security so I'm not invited to conferences like you linked there. I have a mere fifteen years experience in industrial maintenance, nothing like your fifty years. But what I've seen is trying to solder a crimped connection leads to solder wicking up the wire making it stiff and causing to it break. It also damages the insulation and I think the bottom set of "wings" of the Molex KK pins are meant to hold the insulation to provide some strain relief. But I could be wrong.

Are there tools that crimp and solder in one press? If not, it's a business opportunity.

@zapta Yes kind of - some connectors are ultrasonic welded.

Most definitely not something available to the hobbyist nor necessary for a 3D printer.

Pretty cool process nonetheless:
