Correct. That’s what I’ve been doing. So far so good!
This used a 1/16″ end mill for the roughing, I’ll never do that again… And a 1/16″ ball end mill for the finish. Took about 20ish hours total. I have a switch that has a relay inside it hooked to the hot end wire connection on the ramps board, so when it’s cutting(printing) the power is turned on to the router and my dust collection. When it finishes one part it parks the router back at zero and shuts down the router and vac. Then I swap out the bit, rezero everything and hit go for the next step.
