Crimping vs Soldering

[MK-X]

Which is recommended for extending wires such as motors and what not? Crimping or Soldering?

[jaguarking11]

Motors I would recommend soldering the wires. However for the hot end and I would recommend crimping.

For all machines with moving parts is criping not an option!

Printers move quite rapidly and have usually thin wires, especially at the extruder where the termistor is connected. If you have a wiring problem there the result would be a mess - hot end overheated, extruder melted and printer close to burning.

You simply cannot solder the hot end wires. Soldering will melt again and disconnect. Crimping and then capton would work. The rest should all be soldered.

Usually the case... But I wanted my resistor in my hot end soldered. I have my resistor leads come out 3/4" and bend upwards. That lets things cool off enough the solder will hold and make a good electrical connection.

Why would that be the case? Both crimping and soldering works when done right, and both can fail when done wrong. Solder itself doesn't take to well to moving about (it cracks), but it is usually not a problem if the cables are properly secured.

All my hot end wires are soldered, thermistor or heater makes no difference. This parts working for month now and over 500 prints. As Roxy described above, the approx. 4 cm length of the heater cartridge or the thermistor are enough to ensure a propper connection.

If you have a wiring problem either way it would lead to a mess. Also I am using a delta printer, none of the wired motor connections are moving. Still stand by your point?

After 23 years experience in preparing rallye cars, 15 years experience in electronics and mechatronics - yes I do!

And when we were using crimps (because we needed special connectors) we additionally soldered it, too.

The reason is simple: With crimping litz wires you´ll pressing them together in a certain order. At the first moment everything looks save, can´t move anything. But by the time (e.g. caused by temperature) and also with the movement the litzes beginns to move a bit and rearrange them. This can be the point where they start to get lose.

Unfortunately I had to learn this lesson on a hard way, had such failures in my rally cars which at the end costs me at least one time a win in a national championship. And in my business it costs me money...
