Here’s the results of my first real attempt at vinyl cutting. I used Ryan’s mount and the cutter from the store. The mount is another piece of clever design as there is some flex in the mount that works like a variable pressure foot. As a result the Z height is not super critical. The blade depth is critical though so you need to follow Ryan’s suggestions for setting it. Of course I tried the hello world of the MPCNC. I used the vinyl as a stencil on birch plywood and used 24 karat gold spray can, that’s what it said on the label anyway. The vinyl stencil produces very sharp and clean lines, another great use for the MPCNC.
I just followed the instructions for the cutter depth from Ryan’s blog post and used Fusion 360 to generate the tool path. I used the 2D trace in CAM, 1500 mm/min for the feed rate and 0.15mm lead in. Tool choice in Fusion 360 doesn’t matter much as the trace function just follows a path. I did use the lead in and that seemed to work quite well.
