Hi all. I have purchased a festool ets ec 150/5 eq sander, it has the speed control 1 to 6 , for sanding hardwood and epoxy as in river tables what is the speed that is best to select, bearing in mind that the finish grit will be anything up to 1500 grit and starting at 80 grit.
 
I do not own a Festool sander (yet). I have used other brands of RO sanders, none of which were variable speed. I've never had an issue. I tried downloading the pdf of the manual but all I got was a blank page.
 
Virtually every "non-adjustable" sander out there runs at the maximum speed of its variable speed cousin. So, some engineer has decided that max is probably the most common.
It's the same with trim routers.
Some guys slow down with Rotex sanders, though I do not. I'm much more likely to slow the extractor than the sander itself.
However, with pneumatic sanders, I am just the opposite. I never run them at max speed, but in many cases that is because the air pressure is too high.
 
From the manual:
5- 6
- Sanding with max. abrasion
– Sanding off old paint
– Sanding of wood and veneered surface prior to paintwork
– Intermediatesandingofpaintworkonsur- faces
– Sanding thinly applied undercoat
4 - 5
– Sanding wood with nonwoven pad
– Edge breaking on wooden parts
– Smoothing primed wooden surfaces
3 - 4
– Sanding solid wood and veneered edges
– Sanding rebate of windows and doors
2 - 3
– Intermediate sanding of paint work at edges
– Light sanding of natural wood windows using nonwoven pad
– Smoothing wooden surfaces using non- woven pad before staining
– Rubbing or removing excess limestone residue using nonwoven pad
– Intermediate sanding of paintwork on stained surfaces
– Cleaning natural wood window rebate us- ing nonwoven pad
1 - 2
– Sanding stained edges.                                                                                   
– Sanding of thermoplastics

 
I've done a couple of epoxy & wood projects and I dropped the speed back to 2 or 3 as I didn't want to put any heat into the epoxy. A 150/5 is fairly aggressive so I'd start off low and then ramp it up as needed. Speed will also change depending upon grit size and the sandpaper you're using.
