Installation Guide
Tools Needed:
- Hex wrenches (included)
- Allen keys (included)
- Screwdrivers (flat and Phillips)
- Pliers
- Leveling gauge
Step-by-Step Installation
- Unbox and Check Components: Carefully unbox all components and verify all parts are present according to the parts list.
- Frame Assembly: Assemble the aluminum extrusion frame using the provided screws and brackets.
- Install Z-axis: Mount the Z-axis stepper motor and lead screw assembly to the frame.
- Install X and Y Axes: Assemble the X-axis gantry and Y-axis bed assembly with proper belt tension.
- Electronics Installation: Mount the mainboard, power supply, and display unit in their designated locations.
- Wiring Connection: Connect all stepper motors, endstops, heating elements, and thermistors to the mainboard.
- Bed Leveling: Perform manual bed leveling using the paper method to ensure proper first layer adhesion.
- Test Run: Run the printer through a calibration routine and test print to verify proper operation.

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.
MK8 Extruder
MK8 extruder with upgraded spring provides consistent filament feeding and better extrusion performance.
Carborundum Glass Bed
Ultra-flat carborundum glass build plate provides excellent adhesion while printing and easy removal when cooled.
Meanwell Power Supply
High-quality Meanwell power supply ensures stable voltage output and safe operation during long printing sessions.
Upgradable Design
Open-source design allows for extensive modifications and upgrades including auto bed leveling and silent stepper drivers.
Printing Technology Explained
FDM Technology
Fused Deposition Modeling melts and extrudes thermoplastic filament layer by layer to create 3D objects.
Bowden Extruder
Lightweight print head design reduces moving mass for faster and more precise printing movements.
Thermal Runaway Protection
Built-in safety feature that automatically shuts down heating if temperature exceeds safe limits.
SD Card Printing
Offline printing capability allows operation without computer connection once print file is loaded.
Manual Bed Leveling
Four-point manual leveling system with sturdy springs allows precise adjustment of build plate.
Filament Runout Detection
Optional sensor can pause print when filament runs out, allowing for filament change and resume.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Printer won't start | Power issue, faulty power supply | Check power cable connection, verify power switch is on |
| Poor first layer adhesion | Bed not level, wrong bed temperature, dirty build surface | Re-level bed, increase bed temperature, clean with isopropyl alcohol |
| Filament not extruding | Nozzle clogged, extruder gear slipping, wrong temperature | Clean nozzle, check extruder tension, verify temperature settings |
| Layer shifting | Belt tension too loose, mechanical obstruction, overheating drivers | Tighten belts, check for obstructions, ensure proper cooling |
| Stringing/oozing | Retraction settings incorrect, temperature too high | Adjust retraction settings, lower printing temperature |
| Warping/corner lifting | Bed temperature too low, cooling too fast, draft in room | Increase bed temperature, use enclosure, reduce cooling fan speed |
Common Issues
- Under-extrusion: Check filament diameter settings, extruder calibration, and nozzle for clogs
- Over-extrusion: Reduce flow rate, calibrate E-steps, check filament diameter settings
- Z-axis binding: Ensure lead screw is straight and properly aligned, lubricate if necessary
- Thermal runaway error: Check thermistor connection, replace if damaged
- SD card not reading: Format SD card to FAT32, ensure proper insertion
- Blobbing/zits: Enable coasting, adjust retraction, check linear advance settings
