Description:

• Author: Zachar Čuřík
• Launch Date: Q4 2025
• Version: game_save=556, level=03, game_over="unknown"
• Project by: Urobotos Coding

Specifications:
Motion: XY Core
Printable area : 235x235x220 (XYZ, hard Z max is about 240mm)
Home position coordinates: X: -6mm  Y: 254mm  Z: ~ 0,650mm 
Used frame: Voron Trident 250
Extruder: BMG dual drive, Nema 17 pancake, EBB42, Turbo (part cooling) Fan, Electronic and stepper fan cooling, 3D-Touch, TriangleLab TD6s Heatsink + TUN volcano nozzle.

Main Features:

• Emergency STOP switch located at the front of the printer. (Powering the printer ON and OFF is managed via the web interface using the PSU relay remote control).
• Wi-Fi antenna (with BTT-Pi version).
• Exhaust cassette filter (with replaceable carbon filters) and three exhaust fans for print Cooling and Air filtration (Adjustable via Slicer in filament settings).
• Fully enclosed chamber with front door, lighting and top handles for easy handling.
• Electronics housed in the rear section (easily accessible).
• Removable upper plexiglass panel, secured with clips.
• Fully automatic bed leveling system:
  Bed tilt adjustment (Bed is mounted on three joint bearings and guided by MGN9 mini rails) and 3D Touch for Bed Mesh Leveling.
• Klipper firmware with full configuration Sandworm macros for printer operation.
• Z endstop positioned on the bed, aligned with the nozzle, using a remote proximity inductive sensor. (Combined with 3D Touch, no nozzle cleaning is required for homing or bed mesh calibration).
• Zonal Heated Bed: Center heating only (110W) or full-bed heating (240W), selectable via a switch on the bed.
• Chamber heating using PTC 300W Heater (available as an add-on) at 230V with fan, acts like a sandworm (as his name suggests) for ASA… also Extruder with features 360° cooling around the nozzle using a Turbo fan, making it an icebreaker for PLA.
• CanBus Toolhead (Only four cables from the board to the extruder).
• Supports printing with: PLA, PETG, ASA, Flex and more.

Print Settings (Applies to all sections in the signpost): 🖨⚙
Material                 - PLA (Chasiss parts), PETG, ASA other (Motion parts, extruder etc…)
Flow Rate              - 0.98 (98% for PLA)
Nozzle diameter   - 0.6 mm (recommended)
Layer Height         - 0.3 mm
Perimeters             - 2 (For motion parts and with 0.4 nozzle use 3 perimeters)
Horizontal shells  - 3 (Top/Bottom)
Infill                        - 25%-30% (According to the mechanical load of the part)
Support                 - No (Some parts have built-in supports)
Z-Hop                     - On
Print orientation   - As in .stl files
Speed                    - 30mm/s
Min. Bed Size:      - 210x210mm (recommended 235x235, 250x210 or similar)

I printed on Printer: 
DIY Cartesian
Print Speed: 30mm/sec
Extruder: BMG, 0.6 Nozzle
Slicer: PrusaSlicer
Engine: Marlin

Features I used for printing:
- 3D Touch and bedmesh leveling
- Bed Skew compensation
- Step per mm calibrate 
- Print Camera and Octoprint remote control
- Diy Cardboard Enclosure

Note: Most of .STL files contain multiple models that can be separated from each other (if necessary). For example in PrusaSlicer: Right-click on the model → Select: Split → To objects. (This also works on the build-in supports and then you can use yours custom).



How to Start: 
If you're ready, just buckle up and start with the Drive Mount section, which describes the initial setup 🚀

After completing all the tutorials on Printables continue to a separate GitHub site where all the necessary Klipper macros for controlling the Sandworm printer are, link: https://github.com/Urobotos/Sandworm
 

Roadmap:
Drive Mount →  Chassis Bottom →  Chassis Top →  Chassis Middle →  XY Axis →  Z Axis →  Electronics →  Extruder →  Filament and Spool  →  Levelup Addons  →  PrusaSlicer →  GitHub

The Roadmap is your navigation helper through the installation progress

If you find an error, inaccurate information, a 3D model with mesh errors in some sections of Printables… or just have an idea for improvement, write a comment in the given section, I will try to fix it as soon as possible. Thank you for your feedback…
