LDO Micron Plus R1 - CoreXY 3D Printer Kit

The LDO kit version bundles key hardware (mainboard + toolhead board, pre-made wiring harnesses, heated bed, power supply, etc.) into a ready-to-assemble package. You spend less time sourcing parts and rework, and more time on building and tuning.

Ideal for high-speed, high-quality prints, large engineering parts, reliable enclosed printing with ABS/ASA, and long-term compatibility within the open-source ecosystem—including toolheads, probes, lighting, filtration, and more.

LDO Upgrades &Improvements

01. Integrated electronics (Leviathan V1.3 + Nitehawk-36)

The kit includes both boards with matching pre-made harnesses, resulting in cleaner wiring, more straightforward bring-up, and easier service or replacement later.

02. Dual-shear motor mounts + long-shaft motors (LDO-35STH52-2004AH(S35))

XY motors are mounted in a dual-shear configuration for higher rigidity and reduced deflection. Long-shaft motors keep compatibility and leave room for future AWD-style upgrades.

03. Live Idlers + dowel-pinned ABZ pulleys

Live Idlers improve belt tracking, and dowel pins ensure accurate ABZ pulley positioning. The belt path is more precise and tension is more uniform, reducing noise and wear caused by assembly tolerances.

04. Under-bed function PCB (bed fans & filter)

A dedicated under-bed PCB consolidates wiring for bed fans and filter-related peripherals. Cable routing is cleaner, and future fan/filter add-ons are easier.

05. 300 W AC bed heating solution

Uses a 180 x 180 mm, 300 W AC silicone heater for faster heat-up and more stable high-temperature printing.

06. LDO Compact PSU (275 W 24 V + 25 W 5 V)

Compact dual-voltage power solution that saves space and provides convenient 5 V power for loads like an SBC or screen.

Printed Parts Options (Self-print / Pre-printed Service)

Choose the method that best fits your tools, time, and preferences.

Option A: Print It Yourself (Recommended for Printer Owners)

• More Reliability: Follow our detailed print settings profile to achieve successful, warp-free parts with fewer test iterations.
• Guided Consistent:  Use the comprehensive Printed Parts Guide to avoid missing components and assembly rework.
• Get Started: [Micron.STLs]

Option B: Order Pre-printed Parts  (For No Printer / Time-Sensitive Builds)

• Build Immediately: No 3D printer? No problem. Start your project as soon as the kit arrives.
• Simple Add-On: Select the “Pre-Printed Parts Service” during checkout. Parts will be carefully packed and shipped together with your main kit.
• Color Options: Standard two-tone (Primary + Secondary). 【For custom color requests】, please contact support or add a note to your order.
• Lead time: Made-to-order; typically ships ~4 business days later (adjust per production capacity).
