I have used that Amana Tool RC-3400 with pretty good results. My dialed in settings were:
The only trouble I had was with the imperfect tramming of the Avid (have a 2x3 Benchtop Pro), nothing to do with the cutter. Surface quality of the cut was great, but you could catch the edge of the passes with a fingernail. Good enough for the project at the time, but wish it was better and doubt that I can reliably get a better tram across the whole X axis range.
So, I also got a Datron 0068444, haven’t tried it yet - the hope is a smaller diameter cutter would be less sensitive to the imperfect tram.
