Embedded Firmware for 2D and 3D printers.

Custom firmware research and development. Linux / Unix C++ / C / Assembly

I architected an electromechanical print system from print head and electronics back through embedded imaging pipeline to the Windows driver components. Design of Experiment and root cause analysis to isolate existing system flaws and failings.Electromechanical specifications for improved performance.Linux / Unix custom electronics drivers.Linux / Unix image rendering pipeline.Invented new compensation algorithms for thermally induced image defects.Developed ImageXpert image analysis programs for defect detection and measurement.Hacked a high DPI scanner into a precision microscope for image analysis.

Moved to the Small Systems / Desktop division.Radically improved the print quality of the desktop product family via custom image processing algorithms to compensate for printer defects. The family was relaunched with Advanced Imaging Technology brand.Supported launch of new product platform with speed increases, further quality improvements, improved supplies, defect tolerant firmware. Ribbon handling, motor control, communication. Real time systemsC / AssemblyStepper motor control

Large Systems Division Real time system control of stepper motors, print heads, sensors. Custom operating systems. Drivers for custom electronics. C / Assembly
