First, the sauce: http://ift.tt/2i24CqO are you looking at? It’s a failed jst xhp connector from a cable from a fan on one of my parts.What’s wrong with it? It’s soldered instead of crimped.Why did it fail? Solder is not flexible. Crimp connectors have a very important design feature: strain relief. This allows the tiny wires in a stranded cable to flex, but not more than their bend radius. By soldering, they defeated the most important feature of a crimp connector.So the wire broke inside the sheath and the connector looked like it was still connected. But the fan didn’t blow at all.Why did they do it? Nobody in the building that did this had any idea how to connect wires together. Let this sink in for a minute.This isn’t anything “advanced” like cross talk or coupling. This is the electronics equivalent of plugging in a light bulb and they went out of their way to get it wrong.You can and will be troubleshooting things that dont make sense because they shouldn’t be happening.This part was also from the highest rated seller with hundreds of orders.I’m not really meaning to shit on Chinese manufacturers here and I’m personally happy with my purchase. But this is a PSA to anyone who is shopping for a printer based on specs. There will be issues that, without lots of outside context and experience, will leave you frustrated and hating this hobby.Do you have a microscope, crimper and multimeter handy? Are you really comfortable with using them? Because you may not be printing with your clone as much as you’re using these tools. http://ift.tt/2hMxlNp
