So, drilling out the plastic in the clogged tips works fine. I started a print today and guess what? Same crap. It mostly clogs during the first or second layer, but it does seem to clog in the same region regardless of what layer it's on. Once the head gets into the rear, right hand, quadrant of the print bed, that's when it starts. So I'm wondering if it's a broken wire of connector issue like you said earlier now. Once the head bends the wires in the direction, it stops pushing filament. I'll try to mess with it some more. Dang frustrating. I circled the area where it normally clogs in red. The more I think about it, the more it seems to almost always happen in this region. 

The head does have the little hooded cover over the connector that is supposed to stabilize the connector, or so I thought. 

 

 

I wonder if maybe the filament gets stuck in that corner in the tube, or the connector loses connection like you suspect.  I personally don't clip the ptfe filament tube on the clip closest to the extruder because I think it's forcing the filament to run a path it doesn't naturally want to 

Also try printing up this connector and see if it fixes it.  This connector makes sure the plug doesn't wiggle.  Also make sure the screw on the plug cover is not too tight.

I'll unclip the tube like you said. I unplugged the connector, spun the connector, and plugged it back in. Maybe some torque will keep it from disconnecting. I'm really leaning towards that is the issue. If it does it again, I'll print the hosing you posted and try that. I made spool holders with bearings so the filament should feed super smooth. The only drag in the system now is the ball where the filament sensor is right after the spools. I had it out of the system for a while but put it back since the bearings make it feed so easy.

Well, apparently I can't just copy and paste the URL. Forum fail.

Well, it's on layer 4 now and in that same zone and not missing a beat. Must be the connector. I'll print the new back-shell/latch/holder thingy tomorrow when this is done. Crazy it's something so dang simple as a wiggling connector. I wrapped the wire harness around the front of the strain relief thingy.
