I also tested this when I had my Rockcliff running, I started off with a speed that was ok and seemed to work, I then turned the speed up on the router and that’s when everything went a wee bit Pete Tong!

Sure enough the cutter started to clog and then started to jam in the Ali, the end result was this:

Now it may have pushed on but I was using some spring clamps to hold the Ali down and as soon as the jamming started the Ali plate started to move and the E-Stop was the call of the day.

I have looked for the "right" speeds for different size cutters but everyone seems to run different to the next man. I think you basically have to work out what works for you in different materials and then log the data for next time you want to do the same kind of job.
