Key Features
Resume Print Function
Automatically saves print progress and can resume printing after power failure, preventing wasted time and materials.
Precision V-Slot Wheels
High-precision V-slot aluminum extrusion and POM wheels ensure smooth and accurate movement on all axes.
MK10 Extruder
All-metal MK10 extruder provides reliable filament feeding with minimal clogging and consistent extrusion.
Carborundum Glass Platform
Ultra-flat carborundum glass build plate provides excellent adhesion and easy print removal when cooled.
MeanWell Power Supply
High-quality MeanWell power supply ensures stable voltage output and safe operation.
Open Source Firmware
Runs Marlin open-source firmware, allowing for customization and community support.
Printing Technology Explained
FDM/FFF
Fused Deposition Modeling/Fused Filament Fabrication technology for layer-by-layer printing
Heated Bed
Prevents warping and improves adhesion for materials like ABS and PETG
Bowden Extruder
Reduces moving mass on X-axis for faster printing and reduced vibration
Manual Leveling
Four-point manual bed leveling system for precise first layer calibration
Filament Runout Sensor
Optional sensor detects when filament runs out and pauses printing
SD Card Printing
Standalone operation via SD card without computer connection
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Printer won't start | Power issue, faulty power supply | Check power cable connection, verify power switch position |
| Poor first layer adhesion | Bed not leveled, incorrect nozzle height | Re-level bed, adjust Z-offset, clean build surface |
| Filament not extruding | Nozzle clogged, extruder gear slipping | Clean nozzle, check extruder tension, increase temperature |
| Layer shifting | Belt tension, mechanical obstruction | Tighten belts, check for binding, reduce print speed |
| Stringing/oozing | Retraction settings, temperature too high | Adjust retraction settings, lower printing temperature |
| Warping | Bed temperature, cooling, adhesion | Increase bed temperature, use enclosure, apply adhesive |
Common Issues & Solutions
- Under-extrusion: Check filament diameter settings, extruder calibration, nozzle for clogs
- Over-extrusion: Calibrate E-steps, reduce flow rate, check filament diameter
- Bed leveling issues: Use paper method for proper nozzle gap, check all four corners
- Thermal runaway: Check thermistor connections, replace if damaged
- Z-axis binding: Lubricate lead screw, check alignment, adjust coupling
- SD card errors: Format SD card, use smaller capacity card, check file names
