I am 100% sure the problem I am having is not caused by extra friction. I just ran a print and the flow sensor triggered pausing the print twice when there was only a foot or so of filament stickup out the back of the printer with no spool involved. I took the everything apart, feeder, bowden tube, every last bolt and part laying on the floor cleaned and reassembled. I will see maybe tomorrow or Thursday if it fixed the problem. There was a bit of dust in the feeder box, but not a lot. The tube was clean. Nothing was on the sensor.
At this point if I had to venture a guess I have a faulty sensor.
