Greetings all, I have just received my shiny new E3D-v6, after using the Solidoodle 2G with its stock hotend for almost a year. When assembling the fan to the polycarbonate duct, it seems like the holes are significantly too small for the screws- to the point where trying to install them, it feels more likely to strip the socket on the screw with the screwdriver than drive the screw in. Has anyone else had this problem? I am planning on drilling out the holes slightly- easy fix, but thought the E3D team may want to know about the possible quality control issue. Thanks for any comments, DanZo
Mine were a tight fit, but I didn't strip the screw heads - although obviously you must use the correct-sized screwdriver with the bit in good condition. If the screwdriver feels at all sloppy in the screw head, find another screwdriver that fits better. Having seen how much the head gets shaken around in use, you really don't want any loose screws...
I have the same problem. I screwed them in as far as I could, but the screws are still sticking out and seem to rattle a bit.
I have the right size screwdriver and managed to get 3 of the screws all the way in, but the 4th one stripped completely and sticks out a bit. Also, the fan duct became loose against the heat sink so the hot end rattles a bunch during prints. It's a huge bummer!
The holes provide a very tight fit. To screw it more easily, screw for ~3/4 turn and unscrew ~1/4 turn and continue until done. Keep doing this quickly so that the heat produced by friction will allow the plastic to soften a bit.
Thanks for the suggestions (and the knowledge that I'm not crazy ) I ended up drilling the holes out just a tad, and adding some washers to the one screw that still just wouldn't go in all the way. Been on there stably for the last two months like a champ. KidAirCrash, I did also notice the looseness of the clip on the heat-sink as well; used a zip-tie to hold it on snugly.
