After reading about feed speed based on the info from @UnionNine, I reduced the feed rate to 35in, and set the stopover and depth per pass to half the cutter diameter. This yielded better results and allowed me to complete the lighted sign project I had been waiting to do since ordering the Nomad. The photos below show the sign both on and off. The name is cut to a depth of 3mm in 6mm thick plexiglass. The base is pine, and of course needs some stain.
I initially used the speeds recommended by the ‘Carbide Auto Toolpath’ in the tools dropdown menu. That caused problems, and after significantly reducing the speeds things started working better. I wonder if the AutoToolpath Wizzard needs to be revisited with different numbers. It seems like new guys would try that first so they should have know good parameters…
I still see problems with the the parallel finish pass. What I am seeing is that in some parts the roughing and waterline do not cut in a particular area, so when the parallel path starts it is taking a bite which is the full thickness of the wood and that is too much for the Nomad so it stalls then takes off in the wrong direction. If I do not do the parallel cut things work, but I am left with material I wanted removed. Anyone see this sort of issue or have ideas on what to check?
It seems like roughing and waterline should take away material so the parallel finish is just removing a small amount. For some reason this is not happening with some parts and the parallel cut tries to remove way too much material at once.
The sign in the photos below was the practice piece, now I can try something more interesting. The light comes from LEDs in the base that shine up through the acrylic.
