Hello. Today, I updated my three A1 mini printers with this new firmware. The printers are brand new (not more than 1 month old), and I am now experiencing issues with the first layer; it’s not a major problem, but in some areas, the lines aren’t adhering well to one another. After completing the update process for each unit, I followed the same steps: I turned them off, unplugged them from the power source, turned them back on, and ran all the calibration routines. I also checked and tightened any screws that might be contributing to this and recalibrated them again, but nothing has worked. I didn’t have this issue before the update; as I mentioned, it’s not a critical problem, but the printers are no longer able to produce a perfect first layer. I’m not sure if the issue lies in the Pressure Advance calibration process or if the Z-offset has changed following the update, but I get the impression that the lines are now thinner.
I am very meticulous when it comes to my printers; I take great care of them, ensuring they are always clean and perfectly lubricated. I also make sure all the screws are tightened—well, the ones that are supposed to be, of course, since some should only be tightened in specific cases. I mention all this because I’ve already checked everything that could possibly be checked. Even though it seems obvious that the issue lies with the firmware—given that all three printers started behaving exactly the same way after being updated—I checked everything else just to be sure, but it didn’t help.
In the latest version, there were actually no significant changes to the printing process itself. Most of the improvements were focused on other areas.
Version 01.08.01.00（20260603）
Language Support: Added support for Thai, Vietnamese, and Indonesian.
- Filament Presets: Added a new preset for PLA Pure filament.
- Security Enhancements: Included necessary security updates.
- Chamber Light: Fixed an intermittent flickering issue with chamber light.
- External Spool Printing: Fixed an issue where the feed and retract process for external filament would malfunction during a print pause.
- Flow Dynamics Calibration: Fixed an intermittent undefined during the Flow Dynamics Calibration process in print jobs.
If you’re really convinced that the issue is caused by the new firmware, you can always roll back to the previous version. That should quickly show whether the problems disappear or if something else is causing them.
thats not the last firmware, the 3 printers updated today to 01.09.00.00 version
