Firmware Update 1.1.0 Summary - January 26, 2026
This update brings functional improvements, bug fixes, and noticeable optimizations for print quality, usability, and reliability.
Intelligent Features & Diagnostics
-
Enhanced AI Defect Detection
The AI defect detection has been revised to significantly reduce false alarms (false positives). -
QR Codes in Error Messages
Certain error messages now include QR codes that directly link to official troubleshooting guides – faster problem resolution without searching.
Print Quality & Mechanics
-
Increased Z-Axis Motor Power
Z-axis motor current parameters have been adjusted, providing more torque. This resolves quality issues caused by weak Z-axis movements. -
Selective Flow Calibration
Flow calibration can now be performed individually per toolhead. Previously calibrated toolheads do not need to be recalibrated → saves preparation time.
Filament & Material Handling
-
New RFID Filament Types Supported
Additional official RFID filaments are now recognized. -
New Medium Sensitivity Level for Filament Tangle Detection
Tangle detection now offers a medium sensitivity level between “too sensitive” and “too slow.”
Cooling & Noise
- Optimized Fan Control
The logic for cooling fans has been improved to reduce unnecessary noise from inactive toolheads during printing.
Print Time Calculation & Display
- Accurate Print Time Display
The print time shown on the completion screen now reflects the actual print time, with pauses no longer included.
User Interface & Comfort
-
Improved Storage Space Display
Enhanced UI presentation for clearer management of available storage. -
Auto-Refill Enabled by Default
After the firmware update, Auto-Refill is automatically enabled (can still be changed as needed).
Bug Fixes
-
Prevented Firmware Crashes when the start G-code did not include a layer count.
-
Fixed Bug for Unexpected Nozzle Temperature Changes during pre-extrusion.
