FCC ID: 2AVDG-80018XHFW Snapmaker Modular 3D Printer

Make Something Wonderful Three years ago, when we were designing the Snapmaker Original, we broke the rules of traditional desktop 3D printers and created the first modular 3-in-1 3D printer on the market. At first, The Verge and a lot of other reviewers doubted that Snapmaker is an upcoming Kickstarter project with a lofty goal: to be the holy trinity for at-home makers by using detachable modules to convert between a 3D printer, a CNC carver, and a laser engraver, and At the price that Snapmaker is selling, its possible the whole thing is too good to be true. We knew people had a lot of uncertainty about our project and were hesitant to back usbecause of the complexity of designing and making such a product. Despite all the doubts, we worked hard on pushing the boundaries of possibility, and we eventually made the impossible possible. Not only did we fulfill all the rewards, but we also sold over 10,000 units all over the world in 2018. And in 2019, we launched the Snapmaker 2.0. We went beyond our limits once again. Our goal is to build a system behind our modular 3D printers and give you the best maker tools that can work for all your projects. As creatives we all desire to make something wonderful and creativity makes us feel alive. The Snapmaker 2.0 will help you turn your idea into reality. This quick start guide will guide you through your maker journey and take you from building your own 3D Printer/Laser Cutter/CNC Carver to making your first creations utilizing all these tools. Congratulations on becoming part of the Snapmaker community! Thousands of people like you are using the Snapmaker to explore, make, and share in the world of making. We are strong believers that wonderful things will happen when creative minds meet the ideal tools. Have fun making and see you out there!

Team Snapmaker Welcome to the world of making Happy Making This machine is built for innovators. Our goal is to assist you to make the world a better place with a machine we built with love. The difference could be something as small as a Christmas gift, or something as ambitious as exploring unknown territories of our mankind. Dream big and make it happen. Modular System Snapmaker is not only a 3D printer, but also a powerful machine that you can modify with all kinds of addons.

3D Printing 3.2.1 Calibrate the Bed Guides & Pictures / Snapmaker How to Level 1. Run the Auto Leveling procedure on the touchscreen. 2. Place the calibration card or a piece of A4 paper between the nozzle and the heated bed, and manually calibrate the Z Offset for the last point. How It Works: Auto Leveling The 3D printing module conducts a compensation leveling procedure, with the sensor measuring the distance between the nozzle and the heated bed at specific points. The movements of the extruder are adjusted to ensure that the nozzle and the heated bed are at an optimum distance throughout the printing process. How It Works: Adjusting the Z Offset Z Offset is the distance between the tip of the nozzle and the print surface. Adjusting the Z Offset is the process of tweaking the height of the nozzle by tiny increments. A proper Z Offset value helps ensure the first layer of your print sticks to the print sheet. Filament Too Low 48 |

Keep adjusting the height of the nozzle using Up and Down buttons until there is slight resistance when you pull out the calibration card, and it should be wrinkled when you push it forward. Tap Save to save the calibration settings. Slight Resistance Wrinkled Calibration Card Quick Start Guide | 49 3D Printing 3.2.2 Load Filament Guides & Pictures / Snapmaker 2. Tap Start on the Load Filament screen. After the temperature reaches the target temperature, tap Load and then gently push the filament into the 3D printing module until you can feel the motor pulling the filament in. How It Works: Filament Loading The motor drives the filament into the extruder, then the filament extrudes through the nozzle after being heated by the heated block. You can change the target Nozzle Temp by sliding the scale bar. 3. Clean the nozzle using the tweezer, then tap Done. How to Load Filament 1. Hang the provided PLA filament over the filament holder. Cut the bending end of the filament using the diagonal pliers, then insert the filament into the 3D printing module. If there is no filament coming out of the nozzle, do not tap Done until you repeat the steps above and the filament extrudes successfully. 50 |

. You can also upload your own files by clicking Open File in Editor and configure the file settings. Zoom into the image and move the lines until they perfectly match the square, click Confirm ->

Apply to see the finished image. 1 Click Confirm and the finished image will be loaded into the quadrant in the coordinate system. You can repeat the steps above if the edges of the captured image are still not aligned. 3 2 8 7 4 5 6 You can also start engraving/cutting by using the USB disk, connecting with the USB cable, or sending G-code files via Wi-Fi. For detailed instructions, please refer to our online user manual. Unlike the Camera Capture method, you will need to set the work origin if you use the methods above. 4.

The work origin corresponds to the (0, 0) If you need to adjust settings, you can either tap Adjust Settings on the Preview screen or swipe left on the carving progress screen. 2. Tap X-/X+/Y-/Y+/Z-/Z+ to move the CNC bit to where the work origin will be (In this case, we set the center of the image as the coordinate origin in the software). Now the CNC bit should be about 5 mm away from the material. 84 |

Quick Start Guide | 85 5 mm CNC Carving 3. Place the calibration card or a piece of A4 paper between the CNC bit and the material. Keep adjusting the height of the CNC bit using Z-/Z+ buttons until there is slight resistance when you pull out the calibration card, and it should be wrinkled when you push it forward. Tap Set Work Origin. 5.3.3 Clean the Finished Work and the Machine Guides & Pictures / Snapmaker Slight Resistance 1. Remove the clamp set from the CNC carving platform. 0.1 mm Wrinkled Calibration Card 4. Tap Z+ to lift the CNC bit until it is above the clamp set, then tap Run Boundary to check if the work origin is proper. If part of the boundary runs beyond the material or the CNC bit runs into any portions of the machine, reset the work origin and run boundary again. If you have run boundary with the CNC bit above the clamp set, you can lower the CNC bit to run boundary again as you need. If the CNC bit runs into any portions of the machine, power off the machine immediately and check if the CNC bit is damaged. Change the CNC bit if it is damaged. 2. Clean the finished work and the machine using the dust collector, then remove the finished work using the Diagonal Pliers and complete theassembly. 5. Tap Start to start carving. 86 |
