Summary
👤
Senior🎓
Top SchoolAlexander Poss is a Vienna-based software engineer with 14 years of experience specializing in embedded systems, motion control, and polished machine UIs using Qt/QML. As co-founder and active contributor to the MachineKit project and a contributor to widely used open-source tools like Slic3r, he bridges low-level control and high-quality human interfaces for CNC and 3D printing ecosystems. He has run a consultancy helping manufacturers and robotics teams ship intuitive HMIs, trained development teams in Qt, and recently joined Loxone’s Config team to apply his UI and embedded expertise at scale. Alexander combines academic excellence in embedded systems (MSc summa cum laude) with hands-on firmware, backend and tooling work—often implementing niche G-code flavors and advanced status/control integrations that few engineers tackle.

Contributions summary:Alexander's contributions focused on extending the G-code generation capabilities within the slic3r project. They added support for the Machinekit G-code flavor, including specific commands for retraction and unretraction. Furthermore, the user modified the GUI to enable firmware retraction for Machinekit and updated the G-code output to incorporate an end program function. Finally, they switched to the use of the "P" parameter in Machinekit for certain G-code commands.
