Build XY Plotter with Dispenser

@danish2051

I can design your PCB from schematic to production-ready files, including: • Schematic Design • PCB Layout • Component Selection • Design Rule Check (DRC) • Gerber Generation • BOM Preparation • Manufacturing Support (JLCPCB, PCBWay, etc.) I have experience with ESP32, STM32, sensor interfaces, power supplies, RF modules, Ethernet, and industrial electronics. Please share the project requirements, schematic (if available), board dimensions, and any special requirements. I can start immediately. Looking forward to working with you.

Hi there, I read your requirements carefully, and as an Mechatronics/Embedded Systems Engineer whose graduation project was a custom-built CNC Plotter / Drawing Machine, I am confident I can build this exact proof-of-concept for you efficiently and cost-effectively. Having already built a functional XY plotter, I understand the practical challenges of linear motion, GRBL controller setup, and precise toolhead control. Here is my proposed execution approach: Mechanical & Housing: I will design a streamlined, low-cost A4 frame utilizing 3D-printable mounts/brackets and off-the-shelf smooth rods/leadscrews to keep your BOM well under ₹10,000 INR. Electronics & Firmware: Configured Arduino + GRBL (or Marlin firmware) driving two XY NEMA 17 steppers and a dedicated motor-driven syringe actuator for precise cream extrusion with programmed retraction to prevent oozing. G-Code Generation: I will generate clean, pre-scaled motion files tracing your requested word in 4 distinct sizes in an elegant style. Deliverables: Complete 3D CAD/STL files, schematics, fully commented firmware/G-code, a clear demo video showing the machine operating, and step-by-step build documentation for easy assembly at home. I am ready to start immediately and look forward to discussing the project details with you! Best regards, Ali

Hello, I can build this XY plotter proof-of-concept with a practical, low-cost design focused on smooth motion and reliable cream extrusion. I will deliver: * A4-size XY mechanical design and parts list * Stepper motor, driver and syringe/dispenser setup * Arduino-based firmware/control * G-code for the predefined word in 4 sizes * Calibration for accurate positioning and extrusion * 3D-printable bracket designs where practical * Complete source files and build instructions * Testing and demo guidance I recommend using an open-source GRBL-based motion system with a simple third-axis syringe actuator to keep the BOM within your INR 10,000 target. Fixed price: INR 12,500 Timeline: 3 days I can start with the mechanical/electronics architecture and optimize the design around readily available parts.

Hello, I understand that you are looking to create a simple yet effective proof-of-concept for an XY plotter that utilizes stepper motors to write a predefined word on paper, while focusing on smooth motion and clean cream extrusion. Your goal is to achieve clear and elegant lettering in four different sizes, ensuring that the design remains efficient and cost-effective. To meet your requirements, I would propose a tailored solution that begins with a robust mechanical design for the XY frame and components, optimized for A4 paper. I will provide a detailed parts list that includes reliable off-the-shelf parts and 3D-printed brackets where necessary. Alongside the mechanical design, I will develop an electronics schematic and firmware using Arduino and GRBL or another open-source control stack to ensure precise operation of the stepper motors and syringe actuator. Additionally, I will generate G-code for the letter tracing in your specified sizes and create a short demo video to showcase the writing results, along with comprehensive source files and build instructions for your replication. Could you clarify if you have any specific preferences for the materials or components used in the build? https://www.freelancer.com/u/proggon Best regards, Wahaj Barlas.

Two things decide whether this proof of concept produces legible lettering, and neither is the XY motion. The motion is the easy part. The first is the font. An elegant script rendered as a normal outline font gives you a G-code path that traces the outline of each letter — so the dispenser draws around the shape and fills nothing, and it reads as a hollow mess. What you need is a single-stroke font, where each letter is one continuous centreline path. Hershey fonts are the standard open-source answer and Inkscape will generate the G-code directly. That single choice is the difference between clean handwriting and an unreadable blob. The second is extrusion lag. Cream does not start and stop when the motor does — it keeps oozing at the end of a stroke and takes a moment to build pressure at the start. Every letter needs a small lead-in and a retraction on lift, tuned to your cream's viscosity. Untuned, you get blobs at every stroke start and trailing tails between letters, which is how these builds fail on the first video. On control: GRBL runs the two axes, and the syringe drives off the spindle or laser output, which gives you speed control rather than only on and off. Within ₹10,000 for A4: aluminium extrusion or smooth rod with printed brackets, two NEMA 17s, a small stepper for the plunger, and an Arduino with a CNC shield. Tight but real. Tell me the word and your cream's consistency, and I will confirm the frame and the nozzle size.

Hi, I can build this XY plotter proof-of-concept around a compact A4 workspace, stepper-driven XY motion, and a motorized syringe/cream extruder. I’ll handle the mechanical design, off-the-shelf parts selection, 3D-printed mounts, electronics, firmware, and motion files needed to write the predefined word cleanly in four sizes with an elegant lettering style. I can keep the BOM within your ₹10,000 target by using readily available components and an open-source control stack such as Arduino/GRBL. I’ll provide the CAD/source files, wiring schematic, G-code, build instructions, and a short demonstration video showing the complete writing process. Question: Which exact word should the plotter write so I can design the lettering paths and four scales around it? Best regards

Hello, I’d be happy to build the proof-of-concept XY plotter for your project. I can design a simple, A4-sized frame with stepper-driven X/Y motion and a motorized syringe/cream extrusion system, keeping the design affordable and easy to replicate. I will provide: - Mechanical design, dimensions, and complete parts/BOM list - 3D-printed brackets and straightforward off-the-shelf components - Electronics schematic and Arduino/open-source firmware setup - G-code to write the predefined word in four different sizes - Calibration guidance for smooth motion and consistent cream extrusion - Source files, build instructions, and a short demonstration video I’ll focus on accurate movement, clean extrusion, and clearly legible lettering in an elegant style while staying within your ₹10,000 budget as much as practical. I’m ready to start with the mechanical layout and low-cost component selection and develop the prototype step by step.
