Step Slicer Engine

Overview

STEP Slicer Engine

An experimental 3D model slicer engine, built on top of a CAD kernel

Why?

• No loss of precision from CAD → STL conversion
• Retain model metadata (units, precision, color)
• Non-planar slicing
• Support for more advanced Gcode words and macros
• Additive + subtractive manufacturing
• Better multi-object support
• Better multi-material support
• Edit model in-slicer
• Exportable support structures

Dependencies

• OpenCasCade > 7.3.0
• TBB
• Doxygen
• Graphviz

Supported CNC software:

• Marlin 2.0
• Klipper
• LinuxCNC
• Machinekit
• Redeem
