Hi, The machine is dialed in and cutting! First job was to cut 36 foam wing ribs. 65mm/sec, 20mm DOC, 3.175mm upcut bit, 8600 RPM (lowest Makita setting). Cuts like butter with a hot knife. Next job was to cut the fuselage out of 19mm plywood. This time, 40mm/sec, 4mm DOC, 6.35mm upcut bit, 19700 (Makita 3.5 setting). Again, like cutting butter with a hot knife. Unfortunately, with 19mm stock, I don't have sufficient clearance to fit the OB dust shield, so I had to follow the cuts with my trusty vacuum machine. I've ordered the 2" higher Y-plates, but that a way off yet... I found this 3D printable vacuum system which looks perfect, however: Vacuum attachment for 65mm CNC spindle. by grubba I've long thought that placing a suction some distance from the spindle itself hoping it might catch the high-velocity detritus from the bit is somewhat optimistic on a good day. This places the suction mere millimeters from the origin of the debris. My hand-held vacuum emulated this, and did a great job of voiding the rubbish. Anyway - here's a short video of cutting my fuselage pieces. Duncan
