Re: the double power cables. Part of the problem may be that I'm wired to think in schematics rather than verbal (all through the wiring section I would have been better served by schematics than the verbal/photo combo). And looking at that power plug, the entire mess they made of how you're supposed to solder it together doesn't help. Not to mention that the cable that came with the kit was enough for one of their power runs, not both. But I have to admit to getting lost in the details once I went from "comprehensive pre-read" to "step by step" phase.
My issue with the extruder is that the order doesn't matter -- some of those steps simply aren't possible without a 5-dimensional screwdriver. We eventually got around the access problem for the motor mount by iteratively dis/re-assembling the extruder until we had the mesh correct. And the issue with the hobbed bolts and the nylocks had my master mechanic ready to commit murder (or at least minor maiming) on whomever was responsible for that setup.
Pins: I linked to both the male and female versions, even though the Hux only uses the females. But I can confirm that the female pins are the same as what came with the Hux kit -- I already had some on hand from Pololu for a different project. Ditto for the housings.
Progress: Had to remove the entire Bowden tube and repeat the 2mm reaming, despite having done that and successfully tested a couple days ago. It would appear that my filament has thickness variations -- I happened to start with a piece that fed, albeit stiffly, but after about an inch widened to the point that it jammed hard in the part of the Bowden tube that was compressed by the brass fitting.
My hot end keeps reporting the same temp I set, up to 300C, but my IR thermometer keeps saying ~30C. I can actually push filament through and it melts and extrudes, but the extrusion is slow, stalls the extruder motor, and comes out of the tip at nearly 90deg to the axis of the hole, as if the hole was drilled off-angle. I'm pretty sure there's something wrong with my hot end. If I change the setting from 250C to 300C, the software reports the actual temp doing that 50C climb in under 10sec. But holding my IR thermometer on the hot end while that happens only shows 1-2C climb.
And now, the resistance from the hot end was enough to kink the Bowden tube where two filament ends adjoined.
At an ambient temp of around 75F, my heated bed thermistor is reporting a temp of 9C, and the hot end shows about 25C.
