Assembly and use

Mounting and application

Documented Ender-3 conversion. As an editorial adaptation assessment, robot-arm use would require evaluating mounting and motion/extrusion synchronization. The inspected evidence establishes no robot-arm interface. [S001] [S002] [S003]

Before sourcing the build

The preserved Parts List/Complete Parts List.xlsx lists an extrusion screw and heat block, plus bolts with unpriced cost cells. Confirm manufacturing requirements and a complete purchasing list; the workbook does not establish a current delivered budget. [S004] Determine moving mass, heater control, flow calibration, pellet feed and orientation limits. [S001] [S002] [S003]

Files and reuse terms

The root license is MIT. It does not establish source availability or reuse rights for every separately sourced control or purchased component. Complete matched electronics, firmware and software source sets remain unestablished, without implying that such files are absent. [S001] [S002] [S003]

The pinned inventory lists SolidWorks assemblies and parts, STL files and a DXF bracket, including screw, barrel and heat-block geometry. These are adaptation starting points, not fabrication-validated parts. They do not establish a complete, matched mechanical and control package. Current delivered cost and measured performance are not established; no hardware was built or tested for this profile.

Cost

No current, complete configuration-specific build cost has been established for this profile.

Source files and licenses
