Hey there today i turned on the machine and the x axis was jamming so i checked the wiring.
I got a Primo with the SKR Pro 1.2 and this housing with DP 15/25 connectors:

On one x axis stepper the connectors were molten together and now i want to ask which cables i should use to prevent this. Some other connections are getting pretty hot but are not molten.
Best Regards
I had two different wires do that as well.
I soldered directly in one case and used a jst-xh connector set on the other. The jst connector socket side required soldering and a crimper was required for the plug.
You can also use the heat gun solder splice connectors that Ryan sells in the V1 shop.
I’m not much a fan of the stepper extension cables, even though they work for most users.
Thank you for the tipps 
I saw that i have some spare JST-XH connectors. I’ll try them.
That is pretty crazy, did you have them folded and taped?
I’d be really interested if you can dissect that failed connector and show us what the crimping looks like on this one wire.
I bet it was either a bad crimp or a bad locking of that pin that is the reason.
I’ve seen that before on 3D printers.
Yes they were folded and taped and i also put tape around the connectors. Maybe there was a heat buildup inside the tape?!
i cant get the cable out but if i look closely i see that the white cable was slipping out to the bottom and you see the loose open cable in the picture. Maybe that slippage was the problem. The white cable was the original shipped whith the machine parts.
It’s a dead connector. Snap it in half.
Interesting.
That’s not a pretty crimp, but it appears the source of the intermittent connection was the pin at the top not making good contact with the socket (body).
It does not appear that the crimp on this wire is the source of the problem.
Note the strands of wire in and around the crimp are not so badly discolored at the entry to the crimp. Note that the further up this assembly you look, the higher the temps were and thus the more discoloration/oxidation of the part.
Thank you for being willing to dissect that connector.
Yeah most likely. I just switch to JST XH connectors and that should do it… hopefully 
Thanks for the help!
be interested in seeing the the other end of the connector because its been very hot aswell
