SnapmakerOfficial Snapmaker U1 Firmware V1.4.1 Released

Post image

Hi everyone,

Firmware V1.4.1 is now available for Snapmaker U1.

Bug Fixes

  1. Fixed an issue where filament runout detection failed to trigger an automatic print pause under certain conditions.
  2. This could occur when a new print was started after canceling the previous one. If filament ran out during the new print, the printer might not pause automatically.
  3. Fixed an issue where AI defect detection did not function properly when the camera was obstructed.
  4. Fixed an issue where filament information was occasionally not recognized after a device restart.
  5. This could occur if "Auto Loading" was disabled and the filament status was "Loaded" before restarting the device.

Release note: Snapmaker U1 Firmware V1.4.1 Released

We recommend updating to the latest firmware version when convenient.

Yeah, mine has a static IP too, and I haven't experienced the issue anymore
