ESP32 Axidraw PCB & Firmware

@amelectronics

Hi, I can develop the complete ESP32-based replacement controller for your Axidraw-style writing machine, covering both the custom PCB and motion-control firmware. I can design the compact 2-axis PCB with two quiet/smooth stepper drivers, USB interface, power management, end-stop inputs and micro-servo pen-lift control. I’ll provide the complete schematic, PCB layout, Gerbers/Drill, BOM with part numbers, and assembly documentation. For firmware, I can implement the EBB-compatible USB command interface so the controller can work with existing Axidraw/Inkscape workflows where the protocol requirements are compatible. I can also handle acceleration/deceleration, homing, stepper motion, pen-up/pen-down sequencing and reliable command buffering. The firmware can be delivered as a PlatformIO/Arduino-ESP32 or ESP-IDF project with full source and build instructions. I can also provide a Python test utility for sending motion and plotting commands. I’ll validate the design with NEMA-17 motors and a micro-servo, including USB enumeration, homing, smooth motion and an SVG/demo plotting test before final delivery. Please share the original EBB board details/pinout, motor voltage/current, servo specification and any mechanical dimensions available so I can finalize the architecture and PCB constraints.

Dear client, As an experienced electronics engineer with a strong background in digital motor control, embedded systems, and PCB design, I believe I would be the perfect fit for your ESP32 Axidraw project. My skills and experience align perfectly with your requirements, especially considering my proficiency in Arduino, Electronics, Embedded Systems, Microcontroller, and Motor Control. I have a proven track record in designing compact, efficient, and highly functional two-axis motor-control PCBs. In addition to this, I have successfully integrated various motor drivers into different applications - including smooth and quiet NEMA-17 steppers for high-speed plotting - making me aptly familiar with the specific needs of your project. Moreover, I bring a unique blend of skills that extends well beyond electronics design including OPAMP-based analog design ensuring low noise special circuits, power electronics applications such as AC/DC and DC-DC conversion (an important aspect for your power management requirements), and the use of tools like MATLAB for simulation. This immediately places me at an advantage over others who might solely focus on the electronic requirements of your project. Delivering quality designs on time is my commitment. Should you need more detailed examples from my previous projects that involved motion-control firmware or ESP32 based solutions similar to yours, please let me know. Looking forward to working with you. Metin

Hi there, I carefully reviewed your requirements and can develop the complete ESP32-based replacement for the original EBB controller, covering both the production-ready PCB and motion-control firmware. I have experience with ESP32, NEMA-17 stepper control, microstepping drivers, servo control, USB interfaces, end-stops, power management, acceleration profiles, homing, and embedded C/C++ development. I have worked with all the main component types and technologies involved in this project and can design the board for smooth, quiet, reliable two-axis plotting. On the firmware side, I can implement an EBB-compatible USB command layer for integration with Inkscape and existing plotting workflows, along with coordinated XY motion, acceleration/deceleration, pen-lift sequencing, homing, and fault handling. I can also provide a Python test utility for validating commands and SVG plotting. You will receive the complete schematic, PCB source, Gerbers/drill files, BOM, firmware source and binaries, build instructions, and assembly/testing documentation. Just send me a message with the existing Axidraw mechanical/electrical specifications and motor details, and I can get started quickly. Best regards, Samuel tshibangu

Hi there, I read through your project details and I’m confident I can deliver a complete, production-ready drop-in replacement for your AxiDraw EBB board—covering both the custom ESP32 hardware and the full EBB-compatible firmware stack. Having designed custom motion-control PCBs and firmware for CNCs and plotters using ESP32 and TMC drivers, I understand the exact requirements for smooth, silent vector plotting without missed steps. Here is how I plan to execute your scope: • Hardware Design: I will use KiCad to design a drop-in PCB matching the original EBB physical footprint, built around the ESP32-S3 with native USB, dual UART-configured TMC2209 drivers for silent stealthChop operation, robust power regulation, and dedicated servo/end-stop headers. • Firmware & Protocol: I will implement the standard EiBotBoard (EBB) command set over USB CDC so it works seamlessly out of the box with Inkscape and existing plotter scripts, complete with smooth acceleration profiles and precise servo sequencing using PlatformIO. • Complete Deliverables: You will receive full KiCad source files, PDF schematics, Gerber/Drill files, an optimized BOM, a concise assembly guide

Hello, I’m an Electrical/Electronics Engineer with 15+ years of experience in embedded systems, STM32/ESP32 firmware, PCB design, motor control, and complete hardware prototyping. Your Axidraw-style controller is a strong match for my experience with stepper motion systems and production-ready electronics. I can design the complete 2-axis ESP32 controller, including two quiet microstepping drivers, USB interface, power management, end-stops, and micro-servo pen control. I will provide the schematic/source, PCB layout, Gerbers/Drill, BOM with exact part numbers, and assembly documentation. On the firmware side, I can implement the EBB-compatible USB command interface so existing Inkscape workflows and plotter scripts can communicate with the replacement board. Motion firmware will include acceleration/deceleration, homing, coordinated X/Y movement, pen sequencing, and reliable step generation without missed steps. I can also provide a Python/desktop test utility for sending commands and performing repeatable motion tests. The firmware will be clean, commented, and delivered with PlatformIO/Arduino-ESP32 or ESP-IDF build instructions. I will validate USB enumeration, motor motion, homing, servo operation, and an SVG plotting test on the completed prototype. I can also work from the existing EBB pinout/mechanical dimensions to ensure the replacement is practical for the current frame. Best regards, Hamza Electrical/Electronics Engineer

@thinkbotictech

Hi can design the ESP32 two-axis controller PCB and develop firmware with EBB-compatible USB commands, stepper acceleration, homing, servo pen control, and cross-platform USB support. I’ll provide schematics, PCB/Gerbers, BOM, firmware source, build instructions, and a Python test utility for SVG plotting validation. Do you have the original EBB board pinout/dimensions and Axidraw frame revision available? Which stepper-driver and USB approach do you prefer, or should I select components based on the required motor/current specifications?

@bohdanmelnykua

Hi! ESP32 motion control is solid ground for me - I've done stepper driving with acceleration profiles and USB device enumeration on embedded targets before, and I'm comfortable with PlatformIO for this kind of board bring-up. For the SVG-to-motion path I'd parse paths into line/arc segments, feed them through a simple step-planner, and keep pen-up/pen-down timing tight so it doesn't jitter on direction changes. I'll include a small Python test script to send a demo plot, same as you described. Do you already have the stepper driver ICs picked (A4988/DRV8825/TMC-series), or is that still open?

@Teust

Hi — I can take this on as a focused esp32 axidraw pcb & firmware deliverable. I would first verify the source and expected output, then complete the work with a clean handoff and a concise QA check. The brief points to the stated project requirements. I can start within the listed delivery window and keep the scope aligned with the brief.
