Why so much dust with my 1400 and edge guide?

[ear3]

I was using a large edge profiling bit on the 1400 today, along with the edge guide and the clear plastic dust shroud that attaches to the guide, and it literally seemed like there was no dust collection at all:

I'm trying to remember, but I don't think I've ever used the edge guide with a profiling bit on the 1400.  Normally I just allow the bearing to ride the edge, and then use the rods and the guide stop on the board for stability, with the router mounted chip catcher (492732) taking good care of the sawdust.  But the bearing on this bit (a 2" diameter pedestal moulding bit) was to provide a setup reference only, and rides below the edge, which is why I used the edge guide instead.  I feel like there's something really simple and stupid I must be overlooking.  It's definitely not the 36mm hose, the bag or the vac, since they all worked fine both before and after when hooked up to other tools.  For reference, here is how I had the router setup:

You may be running the router the wrong direction. That is the only time I get that much dust.

I sometimes do stupid things, but thank god not that stupid.  ;D

I'll test it again tomorrow with the smaller chip catcher and see if I still have the dust problem.

  I have found that the edge guide shroud doesn't work all that well with an edge profile bit. I have actually had much better collection using the top shroud with the edge guide.

I know with mine that if I try to take too big of a bite the chips and the vac don't get along so well, I  get better results with my 2200. What species of wood were you profiling, I find oak and pine foul the DC more often  than others. Also have found that rate of speed or feed can be a factor, not like the old days when I could just let it rip, but better for the lungs and less time on the broom.

Oak at speed 3.

is that a 36mm or 27 mm hose

Have you taken a look inside you vac hose, it looked like you are getting small enough chips.  I have a small site built table I use with my 1400 and and it's edge guide,  I have noticed that I get some fairly long stripes that gets into the hose or blocking the dust shroud of the edge guide, you may have something trapped inside.

36.  And when I use the hose on the Kapex and planer, no problems.  I didn't have time today to run a test, but will probably get around to it in the next few days.
