I am cutting some grooves in my cutting boards and it is sure hard, I mean really hard to keep from burning the wood a little.
The boards are purpleheart and maple.
I have slowed the router down as slow as I can (Bosch 1617) the bit is new and very sharp.
When I slow down to make a corner that is where I have the problem, if I keep moving at a good cutting rate I have no problems.
I am taking very small cuts at a time it try and keep this from happening.
The maple is the worst, I blink my eye and it will burn.

So what am I doing wrong or how can I keep this from happening.
