How to Build a PCB CNC Router Milling Machine
Instructions
1
Measure, mark and cut two pieces of 1-inch PVC pipe, which should be 12 inches long. Measure, mark and cut two pieces of 1-inch PVC pipe, which should be 12 inches long. Measure, mark and cut one piece of 1-inch PVC pipe, which should be 12 inches long. Measure, mark and cut one piece of 1-inch PVC pipe, which should be 4 inches long. These are the sides, back and upright pieces, and neck of your milling machine, respectively.
2
Slide an end cap on one end of each side piece.
3
Brush a layer of PVC cement around the free end of each of the side pieces. Slide an elbow joint onto each piece. Brush a layer of PVC cement around one end of each of the back pieces. Slide one glued end into each of the open outlets of the elbow joints. Rotate the pipe so all of the connected pieces lay flat.
4
Brush a layer of PVC cement around the clean ends of each of the back pieces. Slide the ends into the left and right side of the T-joint. Brush a layer of PVC cement around one end of the upright. Slide the glued end into the top of the T-joint. Brush a layer of PVC cement around the clean end of the upright. Slide an elbow joint on top and rotate the elbow so it is parallel with the side supports.
5
Brush a layer of PVC cement around one end of the neck piece. Slide the glued end into the open outlet of the elbow joint. Brush a layer of PVC cement around the clean end of the neck. Slide the metal closed flange on the neck piece.
6
Measure 1 inch from the ends of each side. Mark the center of the PVC pipe at the measurement point. Position a linear slide at each corresponding measurement. Secure the slides into place with the provided hardware. Use the drill and drill bit to drill pilot holes as necessary.
7
Center the threaded rod across the side pieces, so it is parallel with each of the linear slides. Slide a 1 1/2-inch piece of 1/4-inch tubing on the shaft of the threaded rod on the right side. The tubing will sit over the side piece.
8
Screw the stepper motor on the end of the rod, so it is positioned against the outside edge of the right side.
9
Measure 1 inch from either edge of the rod on the right side piece. Secure L brackets in each position. Drill pilot holes as necessary. Secure the opposite side of the L bracket to the sides of the stepping motor.
10
Measure 1 inch from the ends of each slide. Position a linear slide at each corresponding measurement. Secure the slides into place with the provided hardware. The intersecting slides will form a square shape.
11
Center an 11-by-22-inch piece of Plexiglas on top of the linear slides. Mark the Plexiglas where it needs to be attached to the linear slides. Remove the Plexiglas and drill holes 1/2 inch from each corner. Replace the Plexiglas and secure it to the slides, using the provided hardware.
12
Measure the length and width of the milling motor. Measure, mark and cut a piece of Plexiglas that is 2 inches wider and 2 inches shorter.
13
Secure a linear slide to both edges of the Plexiglas piece cut in Step 12.
14
Center the threaded rod across the side pieces so it is parallel with each of the linear slides. Slide a 1 1/2 inch piece of 1/4-inch tubing on the shaft of the threaded rod on the top side.
15
Screw the stepper motor on the end of the rod, so it is positioned against the outside edge of the top edge.
16
Measure 1 inch from either edge of the rod on the right side piece. Secure L brackets in each position. Drill pilot holes as necessary. Secure the opposite side of the L bracket to the sides of the stepping motor.
17
Secure the milling motor to the linear slides, using webbing and screws.
