After many iterations, today I finally replaced the old pen carriage with the new design. The goal was simple: create a more solid and stable pen movement system while keeping the structure compact and lightweight. The new pen car lowers the center of gravity and improves the overall rigidity of the mechanism, which should help the V-slot wheels run smoother and more precisely. This upgrade is also part of a bigger change in the system. I’m redesigning several components to eliminate previous EMI issues and make the plotter more reliable during long drawing sessions. But in DIY machine building, the real truth always comes during testing. Next step: mounting the motors and running the first movement tests. And honestly, this is the moment when I usually discover the small issues that still need fixing. That’s part of the process. Follow the journey if you want to see how this pen plotter evolves from prototype to a reliable drawing machine. ⚙️ Would you keep the system compact like this, or would you go for a heavier but more rigid setup? Curious about your thoughts. Stay tuned for the first motion tests. #penplotter #generativeart #art

Mechanically ready. Compact geometry. Lowered center of gravity. Ultra-smooth motion on V-slot bearing wheels. Materials: Durapro ABS + Red spectrum PETG Thread Insert: Copper thread inserts Motor: Nema 17 22mm width – small version Motherboard: Arduino uno + CNC Shield V3.0 Motor drivers: DRV8825+heatsink Rods: 3mm hardened CnC Bearing: 3mm Linera bearings This redesign gives me precise pen height control and eliminates the PWM-related EMI issues completely. Next step: wheel assembly + test board integration. Let’s see how it performs in real motion. Stay tuned. 📸⚙️ #penplotter #3dprint #dıy

Part2 – Rods+Stepper motor are mounted! Almost ready for beta test. Stay tuned 📸! #penplotter #cnc #dıy #homeproject

Redesign in progress. Step 1: Reinforcing the new pen movement system with heat-set brass thread inserts. Durapro ABS gives impact resistance. The inserts give mechanical strength. No glue. No compromise. Built for precision. Step 2 coming next. #penplotter #cncbuild #mechanicaldesign #heatsetinserts #3dprinting

This one has been a long journey. For weeks I was fighting with EMI issues in my pen plotter setup. Random noise, unstable behavior, servo glitches the kind of invisible problems that drain your energy more than any mechanical redesign ever could. After testing grounding strategies, shielding, signal separation… I made a decision: I eliminated the servo motor completely. That meant one thing: 🔧 Full redesign of the pen-lift system mechanically and electronically. Today I’m finally ready with the new solution. Instead of a PWM-controlled servo, I redesigned the system around a NEMA17 stepper motor (22 mm body width) dedicated purely to the Z motion. No more spindle-PWM hacks, no more signal interpretation layers just clean step/dir control directly from GRBL. What changed technically? – Dedicated stepper-based Z axis – Fully deterministic vertical motion – No PWM → servo signal translation – Reduced EMI sensitivity – Cleaner grounding architecture The mechanical unit is as compact as physically possible, following the proportions of the current carriage system. Every structural element is 3D printed from PCTG, which gives: • Higher impact resistance than PLA • Improved layer adhesion • Slight flexibility without brittleness This matters in a pen plotter, where micro-vibrations and repeated Z cycles can slowly fatigue weaker materials. Design philosophy behind this iteration: Precision > Convenience Stability > Quick fix Control > Compromise The NEMA17 22mm motor keeps the mass low, while still providing more than enough torque for reliable pen up/down motion. And since it’s integrated directly into the motion system, acceleration and deceleration can now be tuned inside GRBL instead of fighting servo timing behavior. No potentiometers. No PWM guessing. Just motion control. Sometimes solving EMI is not about filtering the noise — it’s about removing the noise source entirely. This is Version 3 of my pen-lift system. cleaner. More compact. Fully stepper-driven. Soon back to plotting. 🚀 #DIY #penplotter #p1s #3dprint

Let’s try something totally different. ⚙️ Yes, there’s always a “better” way — but I’m wired like an inventor: I need a project to build. This setup controls a servo via Arduino Nano, driven directly by the spindle speed signal. Digital signal → physical motion. Simple. Experimental. Effective. #Arduino #CNC #ServoControl #CreativeEngineering #Mechatronics HardwareExperiment BuildInPublic TechArt DigitalToPhysical

What you don’t see in electronics is often what shapes the result. Electromagnetic interference (EMI) is basically invisible noise signals crossing, colliding, disturbing each other. I turned that idea into linework: clean geometry disrupted by invisible forces. #generativeart #penplotter #lineworkart #electronicsart #eminoise

Lineworkart is taking a short winter pause ❄️ Orders continue as usual all pieces will be crafted after Jan 15. Thank you for all the support this year. Wishing everyone a beautiful, calm Christmas and a happy New Year ✨

Don’t blink. Watch it again 👀🔥 3-4 timems 👌. #penplotterart #generativeart #asmr

When your machine decides to fu*** off for a whole day… 🤯 I spent 12 hours isolating the problem step by step, cable by cable, motor by motor and the grand finale? The issue is hiding somewhere around the mainboard / CNC Shield. (Applause for the plot twist 👏😂) Not the day I planned… but honestly, this is part of the game when you build your own tools. Every failure teaches you the machine better than any manual ever will. 🔧 Tomorrow we go again. Fresh coffee, new patience, same mission: get this beast back to life and finish the orders. 💪🖤 Stay tuned the comeback is always stronger than the breakdown. 🚀

A tiny behind-the-scenes update: my plotter is taking an unexpected maintenance break. This means some orders will ship a little later – thank you for your understanding and support. 🙌 I’ll keep you updated and get everything running smoothly again soon. 💛 #artiststudio #penplotterart #lineworkart
