Hi Everyone,
We know V1.5.0 and V1.5.1 caused more headaches than they should have, and we sincerely apologize for that. To make sure we get things right this time, we’re taking a more cautious approach with the next firmware update. So now we’re opening up V1.5.2 Beta Test before an oficial release.
This version has actually been shared with a small group of users through technical support channels over the past few weeks, as a workaround for the print quality issues in V1.5.0/V1.5.1. The feedback so far has been quite encouraging. Now we’d like to invite more of you to put it to the test.
V1.5.2 focuses on Bug Fixes:
Fixed an issue introduced in V1.5.0 where, in some cases, the first layer was overly squished when Heated Bed Leveling was not enabled before printing.
Fixed an issue where the nozzle diameter could be incorrect in some cases.
After installing this firmware version, please complete the following steps:
Run Multi-Toolhead Offset Calibration again with no filament loaded in any toolhead.
Before starting a print, make sure Heated Bed Leveling is enabled so the printer performs bed leveling automatically before printing.
Tester Incentives: Approximately 10 highly engaged participants will be selected to receive a $50 official store gift card(The store gift card is valid for one year from the date of issue).
Testing Focus Areas：
Regression Testing: Ensure that core/commonly used features remain unaffected and perform normally without introducing new issues.
Stability & Compatibility: Assess overall firmware stability, including but not limited to: communication interruptions, crashes, freezes/unresponsiveness, and unexpected error prompts
How to Report an Issue:
Please report issues directly in this post with a clear description and any relevant files (logs, G-code, screenshots, or videos) to help our team investigate.
The U1 is updating as we speak. Just a thought, one of the jobs we were asked, was to “Run Multi-Toolhead Offset Calibration again with no filament loaded in any toolhead.”
For this, all filaments need to be unloaded. Most time switching filament is lost, waiting for the toolheads to warm up. Ain’t it possible, to when you give the order to the U1 to unload multiple filaments, to start warming up all the toolheads? Or perhaps when the first is ready, immediately started heating up the next one. (whili he is still busy with the process of the first one. This could make the process at least twice as fast…
So should I also wear out another drive and get a few nozzles that I won’t get paid for… no thanks, I can do without that. I’m leaving version 1.4.1 on it forever… I’m not some guinea pig footing the bill for you guys!!!
Understand you might have had a frustrating time with 1.5.0/1.5.1 but there’s no need to be rude? Nobody is forcing you to try this beta & at least it can be said SM are learning from mistakes
For what it’s worth I only have the U1 now so can’t afford to be a beta tester for FW at this time, but I am grateful for those that do…
Hi, I know some users might hold for the same reason so the choice is fullly respected. That’s also why I truly appreciate those who do take the time to test with us. I’ll make sure their effort counts.
We’ve made mistakes, no denial there. And we’re trying everything we can to avoid repeating them and to make things right going forward.
Yes, it would probably have been better to simply replace my PEI build plate.
I can live with the damaged nozzles because I had already ordered hardened steel nozzles anyway. That only hurts half as much. I also had two spare nozzles and two spare toolheads, so replacing them didn’t cost me anything. I still have three packs of hardened nozzles lying around, so that really wasn’t the issue.
The real issue is the PEI build plate. It didn’t have a single micro scratch before, and now it’s damaged at the back because of the firmware issue. Instead of replacing it, I was offered a €10 voucher. But I would still have to pay €37 for the plate plus another €13 for shipping, so around €50 in total. That’s simply not a reasonable solution.
Honestly, this has been very disappointing. I have never experienced anything like this with Bambu Lab.
At this point, the only thing that comforts me is that this is a budget printer and the two printers actually belong to my wife. My Bambu Lab printers have been running without any problems.
The first print after flashing the firmware, finished without a problem. (Did the Multi-Toolhead Offset Calibration and Heated Bed Leveling first). This was a 1 color print.
Hi. Is there a way to install the beta firmware from web (fluid or something else), not using a USB stick since i don’t have one right now without an OS on it .
Thank you.
After my previous 2 successful prints, I wanted to print something with a different filament. I changed this, manually (no autofeeder) so no option to load/prime it, this I do usually manually, but forgot it this time. So when my print started, the first minute there was no filament, after that it printed fine, but the print itself couldn’t be saved. so I stopped the print (and removed the printed parts, 2 layers).
Now the filament was loaded, so a restart should be enough. But selecting the previous print on the interface screen on the U1 itself (selecting the same filament etc) it gave an Gcode error. Only thing that worked to get it printing, was selecting print again from SnOrca.
