DW660 VacJet Mount for MPCNC

thingiverse

DESIGNED FOR USE WITH THE STANDARD UNIVERSAL TOOL MOUNT THAT IS AN INTEGRAL PART OF THE MPCNC DESIGN. BEFORE YOU BEGIN, this setup necessitates that you remove the "tool free" spindle lock from your DW660 and replace it with the "DW660_nose_cover." If you do not wish to or are unable to perform this task, then cease immediately. These parts should be printed with 50% infill and 3 perimeters. The only part that requires supports is the "dust_shoe_with_brush." PLA at 100% scale will work perfectly well, and I printed it at a .25mm layer height. The vacuum originates from a shop vac that I have plumbed into my workshop. The hose leading from this plumbing to my MPCNC has a 1 1/4" tapered end. You may need to create an adapter for your own plumbing requirements. Alternatively, you can post a message and I will attempt to design one for you to print if you ask politely. 30-40psi appears to work adequately for me on the air jet. The lower you can go, the less your compressor has to operate. You will also need: Several feet of 1/4" polyethelene tubing to run an air line down to the spindle. 1 1/4" push connect adapter with 1/4" MPT to screw into a standard air compressor hose fitting. 1 90° elbow 1/4" push connect adapter with 1/8" NPT to screw into the "lower_mount_with_air_jet" 1 air inflation needle 2 6-32 1/2" screws 2 6-32 nylock nuts 8" 3/4" PVC "thin wall" pipe (ASTM D-2241) Brush available here: https://www.mcmaster.com/7900T1 Some zip ties. I obtained everything but the brush at Lowes. There is a good chance I will eventually design and add another variation or two of the "dust_shoe_with_brush." There exists a balance between distance from the deck, tool path depth, and brush length/rigidity. The present design is general purpose and should handle a maximum cut depth of 1.5cm. EDIT 7/16/17 Added "dust_shoe_with_brush_long," which is 5mm longer than the standard. UPDATE 9/21/17 Although the original dust shoe has performed admirably, I am not entirely satisfied with the "dust_shoe_with_brush_long" piece, so I am removing it. I purchased some longer brush material and plan to design a shoe for it. We will see how that goes. EDIT 5/11/18 Slight edit to the "dust_shoe_with_brush." I increased the thickness of the shell by .4mm. I had some trouble with the brush channel cracking the inner shell.
