Firmware for Original Prusa i3 3D printer by PrusaResearch
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:2 reviews, 56 commits, 30 PRs in 3 months
Contributions summary:Stepan primarily contributed to the firmware of a 3D printer, with a focus on implementing and optimizing an XYZ calibration algorithm. Their work involved the development of acceleration control, movement optimization, and sensor data analysis, specifically focusing on pattern matching within a 32x32 pixel grid to determine the printer's position. They also enhanced the reliability of the calibration by adding restart functionality to address potential issues and reporting divergence.
