🛠️ CNC Router (LowRider V3 Build)
Status: In Progress
Type: Custom CNC Gantry Router
Base Design: LowRider CNC V3 by V1 Engineering
Build by: Eric Flesher
🔧 Overview
This CNC router build is based on the LowRider CNC V3 design from V1 Engineering — a mostly 3D-printed, large-format gantry system capable of handling full 4′ x 8′ sheets. I chose this model because of its flexibility, affordability, and mod-friendly nature.
🖨️ 3D Printed Components
Every printable part for the gantry was created on my own 3D printer using a red and black color scheme. These parts form the mechanical structure of the machine, allowing for smooth travel on all axes.
-
Gantry structure: Fully 3D printed
-
All stepper motors mounted and wired
-
Color scheme: Red/Black
🧠 Electronics & Control
The heart of the system is a repurposed 3D printer mainboard, rewired and reprogrammed for CNC functionality. I’ve also adapted a touchscreen originally designed for 3D printers to provide simple control and monitoring during operation.
-
Mainboard: Repurposed 3D printer board
-
Touchscreen: Converted for CNC use
-
Wiring: Fully completed and connected
🪵 The Table
To support full 4′ x 8′ material handling, I built a custom table measuring 60 1/2″ wide by 111″ long. The table is made from MDF, which also serves as a sacrificial spoil board in case of overcuts.
⚙️ Current Progress
-
✅ Gantry assembled
-
✅ Motors and wiring complete
-
✅ Table built
-
✅ Controller + touchscreen configured
-
🔲 Gantry test pending
-
🔲 Table-mounted parts still to be printed
🧱 Next Steps
-
Test full gantry movement and calibration
-
3D print and install final table-side brackets
-
Begin first test cuts and tuning
💬 Notes from Eric
This build is not just about making a CNC — it’s about learning everything I can along the way. I’ve repurposed, rewired, reprinted, and customized every element of this setup. Once complete, this router will serve as a platform for future fabrication, mods, and maybe even its own upgrades.
If you’re thinking about building your own CNC — follow along. I’ll be updating this page with my progress, wins, fails, and everything in between.
