Loading Filament

sainSmart INFI-20 Belt 3D Printer User Manual  & troubleshooting 15

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.
    sainSmart INFI-20 Belt 3D Printer User Manual  & troubleshooting 18
  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.)
    sainSmart INFI-20 Belt 3D Printer User Manual  & troubleshooting 20
  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.
    sainSmart INFI-20 Belt 3D Printer User Manual  & troubleshooting 22
  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.
