I’m looking for a skilled mechatronics specialist who can jump straight into the electrical and software-programming sides of my machine-building project. The mechanical portion is already under control in-house, so your focus will be integrating, testing, and refining the control electronics and embedded code that drive the system. You should be comfortable reading and updating wiring schematics, selecting or replacing critical components, and writing clean, well-documented firmware or PLC logic that keeps everything running reliably. If you can also implement quick diagnostic routines and safety interlocks, even better. Scope at a glance • Review existing electrical design, spot weak points, propose improvements • Develop or optimise the control software (C/C++, Python, or ladder logic—whichever best fits) • Support bench-top testing and provide concise build notes so our technicians can reproduce your work Additional Details: A motorized (24VDC M+Encoder) toothed belt linear guide with pneumatic gripper combined with a paternoster system using a 230 VCA motor and 14 sensors. Overall setup involves approximately 16 I/O. Deliverables will be considered complete when the updated schematics, compiled code, and a short commissioning guide are handed over and our in-house tests pass without errors. Let me know your preferred toolchain and how soon you could start.

Hi, I am an embedded systems engineer with over 16 years of experience developing and commissioning reliable control electronics, embedded firmware, PLC systems, diagnostics, and safety interlocks for mechatronic products. I can review your existing schematics, identify electrical and control weaknesses, recommend practical component changes, and refine the software through bench testing until it passes your in-house acceptance tests. My preferred toolchain depends on the installed controller: C/C++ with the vendor IDE and Git for embedded systems, IEC 61131-3 tools for PLCs, and Python for testing, diagnostics, and commissioning utilities. I can also work with your current schematic package rather than forcing a tool change. You will receive updated design files, clean documented source and compiled code, reproducible test/build notes, and a concise commissioning guide. I can start immediately. Which controller or PLC is currently installed, what hardware is available for remote testing, and are there specific machinery-safety standards or existing acceptance tests I should follow? I can also support the project through prototype refinement and preparation for production. Please contact me to discuss details.
