CoreXY vs. Bed Slinger – Which Kinematics to Choose

Printer kinematics determine how the hotend and bed move:

🔵 Bed Slinger (Creality Ender, Prusa MK4): • Build plate moves on Y-axis, hotend on X and Z • Advantages: Simpler design, cheaper, easy to repair • Disadvantages: Heavy bed limits acceleration (suitable up to ~250 mm/s) • Ideal for: Beginners, printing heavy or tall models

🟠 CoreXY (Bambu X1C, Voron, Prusa Core One): • Hotend moves on X and Y, bed only on Z • Advantages: Low moving mass → 10,000+ mm/s² acceleration, 300–500 mm/s speed • Disadvantages: More complex calibration • Ideal for: Fast printing, production printing, advanced users

🟢 Delta Printers (Kossel, FLSUN): • 3 arms move printhead on all axes • Advantages: Fast vertical movement, large print height • Disadvantages: Complex calibration, lower accuracy at edges

📊 When to choose each: • Cheaper start and easy repair → Bed Slinger • Maximum speed and production → CoreXY • Tall models with small footprint → Delta
