S1 Pro Guide🔗

The S1 Pro uses Marlin firmware and requires SD cards with specific formatting.

1. Powering On🔗

The power button is located on the right side of the printer, near the rear.

2. Loading Filament🔗

  1. Place the filament spool on the top-mounted holder.
    Use only spools up to 1 kg in weight.

  2. Feed the filament through the sensor, ensuring it unwinds from the top of the spool.

  3. Pull the filament toward the nozzle, press the extruder lever, and gently insert the filament until it stops.

3. Preparing the Build Plate🔗

The S1 Pro uses a magnetic PEI spring steel sheet with two sides: a textured print surface and a smooth, reflective back.

Info

Ensure the textured side is facing up. The smooth side is not suitable for printing.

Flip the plate if necessary. It is typically stored upside down to avoid contamination.

Note

Avoid touching the textured surface. Oils from your hands can reduce adhesion.

4. Inserting the SD Card🔗

Insert the SD card into the front slot with the gold contacts facing up.

SD Card Requirements🔗

  • Must be FAT32 formatted with MBR partitioning.
  • Only one partition, no larger than 32 GB.
  • For best results, use 8 GB or smaller cards.

Formatting to MBR FAT32 (Windows)🔗

  1. Open the diskpart tool.

  2. Run list disk to identify your SD card.

  3. Check the GPT column. An asterisk indicates GPT formatting, meaning conversion to MBR is required.

  4. Select the SD card: select disk # (replace # with the disk number).

  5. Erase the card: clean.

  6. (Optional) Convert to MBR: convert mbr.

  7. Open Disk Management to create a new volume.

  8. Use the unallocated space to create a New Simple Volume.

  9. Set the size to 32,000 MB or less.
    For best compatibility, 8,000 MB or less is recommended.

  10. Format as FAT32.

  11. Leave any remaining space unallocated.

5. Starting a Print🔗

Tip

The touchscreen is resistive; use your fingernail for accurate input.

  1. On the touchscreen, tap Print to browse SD card files.
  2. Ensure files have a .gcode extension.

  3. Files with .3mf or other extensions will not appear.

  4. Select a file to return to the Home screen. The filename will appear below the nozzle and bed temperatures.

  5. To change the file, reopen the Print menu and choose another.

  6. Press the Print/Stop button at the bottom of the screen to begin printing.

6. First Layer and Adhesion🔗

A successful first layer is crucial. Address any issues immediately to prevent failed prints.

Build Plate Cleaning🔗

Most unsuccessful prints are caused by a contaminated dirty build plate.

  • Soap and Water
    The most effective method. Remove the build plate, then rinse and dry thoroughly before reinstalling.

  • Isopropyl Alcohol
    Useful for quick cleans, but it can leave behind residue if not wiped off before evaporation.

  • Glue or Tape
    While easy and effetive, it's not recommended. These add thickness that can interfere with print quality.

Bed Leveling🔗

While mesh leveling is automatic, physical bed flatness still matters.

If one area prints too high or low, manual adjustment may be needed.

Info

To adjust live Z-height, tap the Z-height option at the top of the screen.

For full tramming and leveling:
Go to Settings → Device → Leveling.

7. Periodic Monitoring🔗

Check your print periodically—especially longer prints. While most failures occur in the first layer, issues like tangled filament or poor support placement often arise later.

8. Print Removal and Cleanup🔗

  • After the print finishes, remove the build plate and flex it to remove the print.
  • The printer will automatically unload the filament. Remove your filament from the machine after use.
  • Cleanup the machine and workspace after usage.
