As to speeds and feeds I find it better to start slow and slowly and gradually bring the speed up.
I have a far more rigid and powerful machine and I don't really cut faster than about 150 IPM, and at about 10,000 RPM.
I DO cut at 250 IPM and higher, but then clamping can become an issue.
I listen to the sound of the cutting and watch the chips.
You do not want to be making powder, you do want to be making chips.
Dust means you are feeding too slow.
I would suggest you start around 50 IPM and try working up from there.
I wish you could turn the RPM down, but there is a RPM to Torque curve you need to be aware of.
Routers are not generally real good at low RPM's
Unless you are a production shop and charge machine time and NEED to be fast - why go that fast?
Some of the people here NEED fast, but a hobbyist generally does not need, fast.
Yes, there is a need to control chipload, but that does not mean fast cutting.
I am very conservative on cutting speeds because I am not a production shop a really not in need of time, and I like to me conservative with the wear on the machine?
