Please share more details about the problem. I can assist in diagnosing the board and if it needs physical checking, you need to ship that to India. However, if you have PCB design files, that would be good starting point.

Hi, I’m an experienced PCB & Hardware Design Engineer, and I can help troubleshoot your PCB and identify why it is not connecting to the machine. I’ll systematically check the board starting from the power rails and power sequencing, USB-C data/power paths, connectors, MCU/communication interfaces, clock/reset signals, and any protection or component-level issues that could prevent communication. I’ll also review the original schematic/PCB design and compare it against the manufactured board to identify possible design, assembly, or component issues. Since you’ve already confirmed the 12V PSU, USB-C cable, Windows/MacBook setup, and power-button bridging, I can build on those tests rather than repeating them unnecessarily. I’ll provide clear findings, explain the fault and answer your questions, along with practical recommendations for the required fix. I’m ready to start and can work with your schematic, PCB files, BOM, photos, and test results.

Hello, I can help troubleshoot your PCB and identify why it is not connecting to the machine. I have 15+ years of experience in embedded systems, STM32 firmware, PCB design, communication interfaces, and hardware debugging. I regularly troubleshoot existing PCB designs and can work from the schematic, PCB files, BOM, and board photos. From the tests you have already completed, I would systematically check: • 12V input and all regulated power rails • MCU power, reset and clock • USB VBUS, D+/D− and protection components • USB/interface IC and communication path • Connectors, pull-ups and other critical components • PCB assembly and possible design/layout errors • Firmware/startup issues that may prevent USB enumeration If you provide the schematic, PCB/Gerbers, BOM, photos and details of the machine connection, I can review the design and identify the most likely failure points. I can then guide the required measurements and isolate whether the problem is in the power supply, PCB hardware, USB interface, firmware, or communication path. My goal is to find the actual cause and provide a practical solution, not simply suggest replacing components. I am ready to start with the files you have. Best regards, Hamza

Hello, I am Muhammad Javed, an electrical engineer with more than 10 years of experience in PCB design, troubleshooting, embedded systems, power electronics, and communication interfaces. I can systematically troubleshoot your PCB to determine why it is not connecting to the machine and identify the actual root cause. I will review the schematic, PCB layout, component selection, power rails, USB interface, MCU, connectors, communication signals, and any critical protection or interface circuitry. The troubleshooting steps you have already completed are useful, including testing the Windows machine and MacBook, confirming the USB-C data cable with an Android phone, bridging the power button, and checking the 12 V PSU. Based on these results, I can guide you through the next diagnostic measurements using a multimeter and, if required, an oscilloscope or logic analyzer. If you provide the schematic, PCB/Gerber files, BOM, firmware information, and clear photos of both PCB sides, I can perform a detailed design review and compare the expected behavior against the actual hardware. I will explain each test clearly, answer your questions throughout the process, and focus on finding the fault without unnecessary component replacement.

@ahmedy607

Hi, I can definitely help you troubleshoot this. Since the PCB has already been manufactured and the issue is with connecting to the machine, I can review the schematic and PCB design and work through the problem systematically based on the tests you've already completed. I’ll check the power path, USB/data interface, connector pinout, reset/enable circuitry, and any communication signals involved to identify the most likely fault. We can also go through a few targeted voltage and continuity measurements to narrow the issue down quickly. Please feel free to check my portfolio for examples of my PCB and hardware work. If you share the design files and a few photos of the assembled board/setup, I can start reviewing it right away. Best regards, Ahmed Yahia

@miguelcen64

Hello, The key part of this project is **finding why the built PCB powers up but still won’t connect to the machine**. I can help you handle this accurately and efficiently without overcomplicating the process. I have hands-on experience with **PCB Layout, PCB Design and Layout, and Electrical Engineering**, including debugging connection faults, power-path issues, and interface problems on assembled boards. For your project, I would focus on **reviewing the schematic-to-board path**, **checking the USB/data and power rails**, and **tracing likely assembly or design faults** so the final result is **a clear diagnosis and practical next step**. I can start **immediately** and expect to complete this within **3 days**. One detail I'd like to confirm before starting: **is the machine connection over USB, and do you have the schematic or board files available for review**? Best regards, Miguel

@alluankit01

Hi, I can help diagnose why your built PCB is not connecting to the machine and guide the repair/debug process. My approach will be to first review the schematic, PCB layout, BOM, photos of the assembled board, connector pinout, machine interface details, and the checks you already performed. Then I’ll trace the likely fault step by step instead of guessing. I can help check: * USB-C power/data wiring * 12V input and regulator rails * Power button/enable circuit * Connector pinout mismatch * Boot/reset signals * Soldering or assembly faults * Missing pullups/pulldowns * Grounding and continuity issues * Layout or footprint errors Deliverables: * Fault investigation notes * Measurement checklist * Questions answered clearly * Repair/rework recommendations * Marked-up schematic/layout comments if needed * Next-step test plan I can work remotely from photos, files and your multimeter readings, or review the physical PCB if shipping is possible. I’ll focus on finding the real cause and giving clear, practical repair steps. Best regards Ankit
