Wow...that's a new one. Mine goes to 100 I believe. I do know that when I'm doing a contour cut, and it has to find the registration marks, I have to take it out of remote mode once it starts cutting in order to get it to cut at the depth and speed I had originally set it at. Then I have to select the settings I had before, and put it back in remote mode.
It defaults to 20 if I don't do that...so maybe it's just a goofy default setting that's over riding for some reason.
