Summary
🤩
Rockstar🎓
Top SchoolTorbjørn Ludvigsen is an experienced embedded and systems engineer with 11 years of hands-on work across C/C++ firmware, motor control, and ML model optimization. Based in Gothenburg, he has contributed to impactful open-source projects like ODrive and RepRapFirmware—improving UART/DMA interfaces and hangprinter kinematics—and optimized VRAM and tracing strategies for Stable Diffusion in a text-to-3D pipeline. He runs a small company focused on Hangprinter work, blending product delivery with the practicalities of accounting and funding, and previously supported Ericsson’s MiniLink product with TDD and C++11 development. His background in engineering physics underpins a pragmatic approach to precision control and resource-constrained performance tuning. Colleagues describe him as curious and willing to “do new things,” from building complete electronic products to pushing the boundaries of large-model memory efficiency.

OO C++ RepRap Firmware
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:27 reviews, 15 commits, 18 PRs in 4 years
Contributions summary:Torbjørn primarily contributed to the RepRapFirmware project by fixing bugs and enhancing the firmware for Hangprinter kinematics. They addressed issues related to typos, sensor support, and mathematical calculations in the movement and kinematics sections. Furthermore, the user implemented features, such as line flex compensation, demonstrating a focus on improving the precision of the printer's movements and control. The user is also developing the firmware for ODrive3, focusing on torque mode to achieve an optimal line tension.
