ROTARY CNC BOTTLE PLOTTER
Introduction: ROTARY CNC BOTTLE PLOTTER
I picked up some rollers, which are probably used in the printer. I came up with the idea of turning them into the rotation axis of CNC bottle plotter. Today, I'd like to share how to build CNC bottle plotter from these rollers and other scraps.
To do this project, I was inspired by <PERSON> with his CNC Drum Plotter: https://www.instructables.com/CNC-Drum-Plotter/
Let’s getting started.
Step 1: THINGS WE NEED
* 1pcs x Arduino Uno R3.
* 1pcs x Arduino CNC Shield V3 GRBL.
* 4pcs x Stepper Motor Driver A4988.
* 2pcs x Old CD/DVD Players.
* 2pcs x Stepper Motor NEMA 17-size.
* 2pcs x Old Printer Rollers, with length about 370mm and diameter 10mm.
* 2 meter x 8P Rainbow Ribbon Cable.
* 2pcs x Aluminum Flexible Shaft Coupling, Inner Hole Size: 5mm x 8mm.
* 1pcs x Aluminum Flexible Shaft Coupling, Inner Hole Size: 10mm x 10mm. It is used to clamp the pen/ pencil.
* 1pcs x Stapler.
* 6pcs x Copper Brass Pillars L-5/10mm.
* 3pcs x Threaded Rod Hangers and Nuts M10 x 500mm. I used threaded bolt type for hanging lights.
* 8pcs x Bearing 8mm ID.
* 2pcs x XH2.54mm – 6P 20cm Wire Cable Double Connector.
* 4pcs x L shape supports.
* 2pcs x Mounting Support for Stepper Motor.
* 1pcs x Power Supply 12V.
* Some small cable ties, cable spiral wrap, M4 bolts and nuts.
Step 2: SOFTWARES
* GRBL firmware.
* Inkscape.
* AxiDraw Software 2.6.3 by Evil Mad Scientist Laboratories. It is optional for hatch fill extension.
* Universal Gcode Sender.
Step 3: ROTARY Y AXIS ASSEMBLY
I reused 2 wooden sticks from my kids toys, drilled 2 holes on each sticks with distance about 65mm and mounted the bearing into drilling holes.
* Blue wooden stick dimension: 100 x 30 x 10mm
* Red wooden stick dimension: 165 x 30 x 10mm
Two printer rollers ends were inserted into bearing of blue wooden stick.
I inserted other side roller ends into bearing of red wooden stick and connected 2 stepper motors Y axis to 2 rollers by flexible coupling 5x8mm. Then I cut a wooden plate dimension 250x350mm to build a CNC footplate and mounted the L shape supports on it. 1000
The stepper motors and red wooden sticks were mounted on this footplate.
Step 4: X AND Z AXIS ASSEMBLY
The X-axis and Z-axis were mounted on a wooden box 12x10x6mm which was drilled 4 holes and inserted 4 nuts M10 into these holes. The distance between the two nuts on one side is 30mm.
The M10 threaded rods were polished at both ends until they reach a diameter of 8mm.
I screwed two M10x500 threaded rods into 4 nuts of the wooden box. Depending on the bottle length, I can adjust the position of the X-axis manually. Four other nuts were also screwed to two ends of thread rods in order to fix the desired position.
For X and Z axis, I mounted 2 old CD/DVD players on the above wooden box 12x10x6mm.
For clamping the pen/pencil, I used the stapler's spring mechanism and flexible coupling 10x10mm. Details you can check at my previous instructable: BACK TO BASIC-MINI CNC PLOTTER
I cut the 2 wood plates with dimension 100x200mm to build the left and right side support of X and Z axis. I drilled 2 holes on each plates with distance about 30mm and mounted the bearing into drilling holes. The other holes were used to connect to L shape supports.
Two threaded rods with two CD/DVD players were inserted into 2 bearings of the right and left side supports
In order to keep the X-axis supports strong enough, I used one additional threaded rod 10x500mm to connect the left and right supports.
The left and right supports of XZ axis were mounted on the CNC foot plate. 226
