2. Please keep the machine away from flammable, explosive, corrosive, or high heat sources. Please place the machine in a ventilated and cool environment.
3. Place the machine on a level and stable surface. Unnecessary vibration or shak­ing will affect print results.
4. This machine is compatible with 1.75mm filaments such as PLA, TPU, and PETG.
5. Only use the OEM power supply cable. The use of aftermarket cables can be danger­ous if they are not properly grounded.
6. Do not touch the nozzle or hotbed when the printer is working to prevent high-temperature scalds and personal injury.
7. Be careful when the machine is operating as clothing, hair, and fingers could easily get caught and cause injury.
8. It is recommended that you remove any debris and clean your printer nozzle after a print while the print head begins to cool.
9. Perform maintenance: Regularly clean the machine body with a dry cloth in case of power failure, and wipe off dust, adhesive printing materials, and foreign matters on the guide rail.
10. For children under the age of 10, please do not use the machine without the supervision of personnel to avoid personal injury.
11. This machine is equipped with a safety protection mechanism. Please do not move the nozzle and printing platform manually when the machine is on, other­wise the machine will be automatically powered off for protection.

3. Insert the positioning pin on the Y-axis fixed plate into the corresponding hole of the aluminum profile, and then lock it with a hexagon socket flat round head screw M5x8.
   

4. Cable Connection:
   1. Insert the Teflon tube into the connector. (Also insert the black clamp.)
   2. Connect the filament sensor cable.
   3. Connect machine base cable.
   4. Conned the extruder motor cable.
   5. Connect the power cable.
   6. Install the spool holder
   

Menu Introduction

Loading Filament

Step 1. Navigate to “Preheat” in the “Prepare” menu and set your nozzle temperature and bed temp to the appropriate settings for your filament.
Step 2. Place your spool onto the filament holder.
Step 3. Insert the filament into the filament detector sensor.
Step 4. Press down on the stepper motor filament lever to insert filament passed the sensor and into the Bowden tube.
Step 5. Feed filament through until you see some plastic begin to extrude from the nozzle.

Leveling

1. Before you start producing your first batches of prints or your inspiring mega prints, we suggest you calibrate your machine by leveling and running a layer test. (Scan the QR code to watch the leveling video.)

2. Adjust the height of your belt.
   Step 1. Navigate to the “Prepare” menu.
   Step 2. Select the “Layer test” function. After waiting for the nozzle to heat up, the nozzle will keep moving and extruding out filament to help you adjust the distance between the nozzle and the belt.
   Step 3. Adjust the height of your belt to make sure the filament is extruded fully and evenly so that your print can well adhere to the platform.
   

3. Press the belt with your hand and if you find that the belt has a bulge, tighten the belt tensioning screws clockwise on both sides to increase the belt tension. You can observe the scales on both sides to make sure the left and right sides are adjusted with the same amount.
   

4. Home the printer and adjust the screws in the Y-axis limit switch to make sure a proper distance between the nozzle and the platform. (Use the 0.1mm feeler gauge to assist.)
   

5. To make sure the nozzle is at the correct height above the platform: First, loosen two fixing screws at the endstop, then turn the bottom adjusting screw to adjust the height of the end stop, turn clockwise to move the nozzle closer to the platform and vice versa. Adjust the nozzle height by a small degree to ensure proper height between the nozzle and the platform when home. Sliding the 0.1mm feeler gauge in between, you should be able to feel slight friction. You can tighten the two fixing screws on the Y-limit switch now.
   

6. Turn the four platform adjustment nuts counterclockwise to lift the platform. All nuts should be adjusted, each rotation should be less than 180°. Use the feeler gauge to test the distance between the nozzle and the platform.
   

7. Check the leveling again with the “Layer test” function, if you still find the nozzle is too far from the platform, repeat step 6 until you get a satisfactory extrusion result.

Printing Your Own Models

1. Installing Software
   1. Check your accessories box for the included SD card.
   2. Install the sain smart belt 3D printer slicer software.
   3. Import the included machine and filament print profiles.
   

2. Print from SD Card
   1. Copy the code file generated to the memory card.
   2. Insert the included SD card into the micro SD card slot near the top of the controller display unit at the top of your 3D printer.
   3. The 3D printer will begin preheating and printing your file as soon as it is ready to begin.

WiFi Configuration

Note: Before enabling WiFi on your INFI-20, please note that the INFI-20 only supports 2.4GHz WiFi, not 5GHz. If your router has these two bands combined, please separate them so that the INFI-20 can recognize your WiFi network. In addition, do not use the same SSID for your 2.4 GI-lz WiFi and 5GHz WiFi.

1. Create a text file and insert the following:
   

2. Insert the SD card into the printer, run the “wifi. code” file, then restart the machine, and wait for the IP address to show up on the screen.
   

3. Open the browser, and navigate to the IP address displayed.
   

Notes: If no IP address is displayed,

1. Please repeat the step.
2. Make sure the password you entered is correct.
