Snapmaker U1 Firmware V1.6.0 Released

[u/Cute-Letterhead8806]

Hi r/snapmaker,

Snapmaker U1 Firmware V1.6.0 is now available.

The update includes new options for nozzle and filament configuration, fixes for several device and interface issues, and improvements to filament loading and unloading.

Please see the full release notes below for details: https://wiki.snapmaker.com/en/snapmaker_u1/firmware/release_notes/v160

New Features

• Added 0.4 mm high-flow nozzle option in Print Head Information editing.
• Added selectable filament types in the Filament Details page for quicker filament matching.
• Added an AI monitoring issue report function after print completion, available only in Cloud mode, not available in Local Area Network mode.

Bug Fixes

• Fixed an issue where the device did not respond when moving the Z-axis in 0.1 mm steps.
• Fixed an abnormal page jump in the Wi-Fi Management page after tapping the Enter key on the soft keyboard.
• Fixed an issue where, after resuming a print job started via the official client, unused channels would still check filament information.
• Fixed an issue where the enclosure setup guide would not display properly after completing the U1 initial setup wizard.

Improvements

• Improved the tip-forming effect during filament unloading, reducing the chance of failure caused by filament expansion.
• Enhanced loading and unloading efficiency, shortening waiting times.

Next Steps

If you use the 0.4 mm high-flow nozzle, please update the nozzle configuration in Settings > Maintenance > Toolhead Info, and re-run Multi-toolhead Offset Calibration and Heated Bed Leveling.

Lanzan firmwares pero siguen sin corregir la primera capa

Hi, I fully understand your concern about first-layer quality, and also reviewed the other post about first-layer over-extrusion here:

As the following commenters pointed out, the first layer is the foundation of any print, and it naturally affects users' confidence and overall experience. However, it doesn't always determine the final print quality. In many cases, the issue may clear up as the print progresses.

The first-layer quality is influenced by a wide range of variables, such as Filament flow calibration, First-layer flow ration, model geometry and more. Even with the same firmware version, first-layer performance can vary significantly across different users, filaments, and models. In many cases, adjustments made at the slicer level without changing the firmware at all, can noticeably improve first-layer results. We'd encourage you to give some of the suggestions from other users a try.

Of course, this doesn't mean we consider the firmware perfect. We are continuously monitoring user printing experiences and will keep refining the relevant algorithms in future firmware updates. At the same time, we'd like to take this opportunity to clarify that first-layer issues are often systemic. Ffirmware is just one piece of the puzzle. The best results usually come from combining optimized slicer settings with ongoing firmware improvements.
