FWIW...I've mounted the ETSC 125 in the Positioning Aid and have been sanding Ambrosia maple drawer front edges. I wanted to remove these blade marks made with a MT 55 and a new blade. They look worse than they really are, some can be caught with your finger nail while others cannot be caught at all. I'd say they're in the .001"-.003" range.

It was relatively slow going using 240 grit Granat, so I decided to swap out the ETSC for the DTSC...still using 240 Granat the job went 50%-70% faster, Then I noticed this.

I never noticed this amount of sawdust when using the ETSC, then again with the ETSC I had to make several passes, wipe the edge, check for marks and then make several passes a 2nd time and sometimes a 3rd time.
Using the DTSC I just ran it down the edge forwards, then backwards and 95% of the blade marks were removed.
I also noticed this when I turned the DTSC over, sawdust being evacuated through only 2 holes...that makes sense. I'm sure paper usage is not optimal and wonder if the RTSC would be better because the paper can be rotated 180º.

All of these drawer fronts were cut to length using a Kapex with a sharp clean blade. The ends were really nice & smooth. I decided to sand the ends anyways and they became like velvet, just incredibly smooth. That's good news for you [member=57948]ChuckM[/member] for your end grain usage.
Finally, I took a piece of Birdseye maple, adjusted the positioner to 45º and took a quick light pass on the edge with 240 Granat. The outcome was a really nice clean, smooth edge break about .035" wide.
