Smxy 3d

Created by @sameer-kulhari

Total Time Spent: 77 Hours

June 12th : Project Ideation and Sketching

  • Started planning the overall design and purpose of the 3D printer on paper.
  • Researched core features to be included in a high-speed and professional printer.
  • Noted ideas around rigidity, performance, and ease of upgrade.
  • Finalized goals like: strong frame, high speed, and high print quality.

Key Features Finalized: - Core-XY motion system
- MGN12 Linear Rails
- Klipper Compatibility
- 310×310×310 Build Volume
- Dual Z-Axis
- Bowden Extruder
- Octopus v1.1 Mainboard
- 4040 Aluminum Frame for stability

Time Spent: 4 Hours

June 13th : Feature Research and Frame Design

I learn and study about various printer builds to get a idea on it and note some important points about the frame layout,structure and allignment So, that my printer build is properly stable and strong to withstand the demands.

  • Studied best practices in frame layout and structure.
  • Compared real-world printers for strength and stiffness.
  • Started listing required mechanical components.

Time Spent: 4 Hours

June 14th : Finalizing Basic Components

I researched about the 3d Printers parts and there types and use cases So , I can choose the perfect and best options for my build to get more performance and quality in printing.

  • Finalized most mechanical parts after researching prices, compatibility, and reviews.
  • Compared 3–4 websites for sourcing.
  • Shortlisted components based on quality .

Parts Chosen: - 2020, 2040, 4040 Aluminum Extrusions
- MGN12 Linear Rails
- V6 Hotend
- NEMA 17 Stepper Motors
- Octopus v1.1 Mainboard
- 8mm Lead Screws

Time Spent: 4 Hours

June 15th : Core-XY Gantry Research

For the Core-XY build i researched about various top Gantry design which are easy to build with less parts and rigidity.Finally i found the CoreXY Frame V2.0 the best option but it also has some flaws.

  • Explored top gantry designs suitable for MGN12-based Core-XY setups.
  • Found CoreXY Frame V2.0 design as a good match.
  • Identified compatibility issues and noted required customizations.

Time Spent: 3 Hours

June 16th : Customization of Gantry & Parts

After knowing about the flaws in the 3d models from CoreXY Frame V2.0 I redesign them with keeping rigidity and compatibility with 2040 in mind.For this take proper measurements and make there proper models.

  • Modified gantry design to support 2040 frame profiles.
  • Designed a custom extruder holder.
  • Enhanced structural parts for more robustness and strength.

Time Spent: 6 Hours

June 17th : Finishing Gantry Modifications

After making the top gantry parts I assembled them and check for any error in it and everything alligned perfectly.Then i make a proper assembly of the parts to see the final look.

  • Finalized tweaks to the CoreXY layout and saved edited parts.
  • Verified alignment and mounting logic.

Time Spent: 6 Hours

June 18th : CAD Part Collection

For full assembly I explored different websites and then dowload all the prebuilt CAD models for the parts to be used in the design and then make a proper folder for them.

  • Searched for and imported CAD models of all standard components from GrabCAD & Thingiverse.
  • Adjusted sizes and geometry where necessary.

Time Spent: 4 Hours

June 19th : Custom CAD Part Design

I look for all other custom parts that i need to make for assembly and after that i took the measurements and made 3d models for them. - Modeled custom brackets, joints, and mounts using Onshape. - Measured physical dimensions of real parts and matched CAD accordingly.

Time Spent: 5 Hours

June 20th : Preparing Assembly Setup

I organised all sub-assemblies and make a full assembly from it and verify the part compatibility to prevent any issues in the future during the build and designing. - Structured sub-assemblies (gantry, base, frame, etc.) to simplify final assembly. - Verified part compatibility across imported and custom parts.

Time Spent: 4 Hours

June 21st : Final Assembly in Onshape

  • Assembled all parts in Onshape with proper alignment and looks.
  • Focused on accurate bolt and nut placements.
  • Took images and screenshots for documentation.

Time Spent: 7 Hours

June 22nd : Web Upload and Repository Setup

  • Created GitHub repository with structure:
    • /CAD
    • /Images
    • /BOM
    • /README.md
  • Uploaded CAD files to GrabCAD and Thangs for open source access.

Time Spent: 3 Hours

June 23rd : BOM & Final Documentation

  • Created a clean, organized Bill of Materials (CSV and Markdown).
  • Documented each section in the README with:
    • Features
    • Instructions
    • Images and Renders
  • Wrote a mini journal and wrapped up documentation.
