Status: Feature Complete - Beta Testing
Upcoming: V1.0 Beta 2

LH Stinger is a no-compromise cartesian 3D Printer designed for speed and precision.
It is created as a long-lasting platform for those who like to push quality or speed to the extreme.
The project intends to become a community-driven project, not a brand.

• Driven by the Octopus Pro 1.1 board with TMC2240 drivers
• Running Klipper firmware
• Easily serviceable external electronic box with good airflow, and support for multiple power supplies, SSRs, RPi and large controller boards.
• Good cable management with a quick disconnect system between the printer and ebox
• Toolhead based on the Dragon HF hotend and HF extender
  • Custom thick silicon sock mold available for RTV casting
• LDO Orbiter 2.0 direct drive extruder
• Dual 5015 fan setup for part cooling
• Adopts the Annex Engineering Quickdraw Probe
• Minimalistic printed parts design focused on strength and easy printability
• Printed in ASA, providing high temperature resistance
• Easily enclosed, with the main electronic components outside of the build chamber.
  • The 200 mm^2 bed configuration can be fully enclose up to the frame bounding box. No extra space is needed for the bed movement.
