I Built a DIY IDEX 3D Printer (Print Two Parts at Once!)

Rebuilt from scratch, this DIY IDEX 3D Printer is a fully custom dual independent extruder system built with V-slot aluminum, smooth rods, and 3D-printed connectors for duplicate/mirror mode printing. Powered by Marlin firmware on RAMPS 1.4 + CNC shield with Arduino Mega, it features two separate X-axes, MK8 extruders, CR-10 hotends, and a 300x300mm heated bed—designed for batch robotics parts at twice the speed. 🔧 Key Features: Fully rigid V-slot aluminum frame with 3D-printed connectors and LM8UU bearings. Dual independent X-axes with separate NEMA17 motors and hotends (true IDEX). 300×300mm heated bed with MOSFET driver and spring leveling system. MK8 extruders + CR-10 24V hotends with dual cooling fans per nozzle. Marlin firmware on RAMPS 1.4 + CNC shield for 6-axis control. Modular design: 0.2mm layer height, 30% infill prints. 📦 Perfect for: Makers printing batch robotics/UAV parts (arms, frames, gearboxes) Experimenters building custom multi-extruder systems DIY builders upgrading from basic Cartesian printers Download files, wiring diagram, Marlin firmware, & parts list: https://themechninja.com/product/diy-...
