Dual Z-axis & CoreXY, Fast 3D PrinterQ1 Pro 3D Printer has independent dual Z-axis motors and lightweight CoreXY system. Maximum speed is up to 600mm/s and 20000mm/s² acceleration. This allows for greater precision and high speed printing while still maintaining printing quality. Full-Auto Calibration & Filament Smart detectionAutomated dual sensors allow for more precise auto-leveling and everything ready for you with smart sensors. As well as the intelligent Hall filament runout sensor and filament tangle detection, it can real-time monitor whether the filament is normal or not during the printing process, to ensure the successful printing, making your every printing easier and more efficient. Active Heating Chamber Temperature Control System Q1 Pro 3D printer can actively heat and regulate the chamber temperature.
