I will program arduino and esp32 stepper motor control with tmc2209 and accelstepper
Electrical Automation Engineer Motor Control PLC Specialist
I am an Electrical and Automation Engineer expert in motor control systems, embedded firmware, and industrial panel design. With practical experience in microcontrollers Arduino, ESP32, STM32 and indu...
About this Gig
Struggling to make your stepper motor run smoothly without skipped steps or overheating? I can write custom, well commented firmware for your Arduino or ESP32 project.
I'm an expert in driving NEMA 17, NEMA 23, and NEMA 34 stepper motors using popular drivers like TMC2209, A4988, DRV8825, and TB6600. Whether you need precise positioning for a custom 3D printer, CNC slider, robotic joint, or automated feeder, I ensure your setup operates silently and reliably.
What I offer;
Clean C/C++ code using libraries like AccelStepper, FastAccelStepper, or CheapStepper. Non blocking execution so your microcontrollers handle buttons, limit switches, and sensors without lag. Homing sequences, soft limits, and speed acceleration profiling. Detailed pinout wiring diagrams PDF or Fritzing so you can wire everything without shorting your components.
I do not sell broken sample scripts. You receive production ready code tuned for your motor specifications. Message me with your driver model, power supply voltage, and functional steps before ordering!

FAQ
Do I need to send you my physical hardware to complete the project?
No. I build and test your firmware using circuit simulation tools (like Proteus/Wokwi) and physical bench setups on my end. I deliver the ready-to-flash code alongside a pinout wiring diagram and a video showing the code driving
Will the stepper motor code freeze or lag when reading sensor inputs?
Never. I write non-blocking C++ code using finite state machines and timer interrupts rather than simple delay() statements. This keeps your microcontrollers responsive to pushbuttons, limit switches, and display updates while
What happens if my motor skips steps or runs hot during operation?
Step loss and thermal issues usually stem from incorrect current limit tuning on driver chips like the TMC2209 or A4988. I will calculate the exact $V_{ref}$ voltage setting for your driver potentiometer and help you configure acc
What files will I receive in the final delivery package?
You will receive the compiled .ino or .cpp source code files, a list of required libraries, a step-by-step flashing guide, and a clean PDF wiring diagram showing pin connections between the board, driver, and power supply.
