Not me, but that’s what he’s cutting. He’s using a “roughing” bit though, so it’s not going to leave the smoothest finish. The aluminum is pretty thin, so I’d just use the cut speeds from the feeds and speeds thread.
Yea, it should help your dremel cut a little better. It’s function is to cut “soft” materials, so plastics and soft metals like aluminum and brass. It gives the cutter a little more cooling off time between cuts. In estlcam on the tool list click on view and select all the trochoidal settings. You can hover over them to get an idea of what they do. I haven’t found a good video of how to set up this kind of cutting yet, so I’m not 100% sure what settings to use. I used the defaults when I cut out some acrylic and it worked pretty well.
I had done the test to see how he behaved the plexi in contact with the bit … and in fact merged making processing impossible. For now I will simply try that trochoidal milling method and then change my tool … can be the right way Barry? Thanks
