I have been checking the backlash on my router and found that the feed rate affects the amount of backlash. At a slow speed, 100-500 mm/m, I get around .1 to .18 mm backlash but at a feed rate of 1000 to 10000 mm/m I get 0.0 to 0.02 mm. I get this result whatever distance I move, 1,10,100 or 500 mm. What reading should I use? I normally cut wood at 2000 to 3000 mm/m so I’m inclined to have no backlash compensation. What would you recommend?

Cheers
