The youtuber " PRINTING PERSPECTIVE" recently made a video about variable temperature printing. I think it would be a very useful feature to have to reduce the amount of cosmetic changes during a print. I.e. becoming slightly more matte during a print when a flow is higher on some part but lower in another. I also suspect this issue causes physical dimension changes (benchy hull line?) on some prints and that using variable temperature would resolve it.
I hope this is something that can be included on the current printers through software.
I saw that video too. This issue highlights the major downside of Bambu. Having a closed architecture is one thing, but blocking third-party support is quite another. I tried this utility myself, hoping to find a Bambu profile. However, it’s a post-processing script that modifies the GCode for Klipper-based open-source firmware printers. Bambu claims their firmware is entirely proprietary, but I’m skeptical based on their past stonewalling when questions arise about internal functionality. It wouldn’t surprise me if there’s a lot of Klipper code mixed with their modifications, but that’s hardly in the spirit of open source.
If Bambulabs were truly supportive of their customer base, they would provide a profile for their printers that are suitable for use in open source projects like this. However, we’re just lucky that they even post all their error codes.
Bambulabs: If you’re truly listening, here’s a golden opportunity to show off if you’re truly supportive of your customer base or you want to keep closed behind the Bamboo Curtain. Support this effort. Provide either a JSON config file that will work with your firmware or roll your own code and release it to the public. Now’s your chance to either decide whether you’re the good Grinch or the bad Grinch
If I remember correctly the X1 Plus team confirmed the firmware is not Klipper or Marlin. Believe this also came out during the fake hacking of an X1 a year or so ago. Currently searching source but I really doubt they would run even modified klipper and risk not disclosing this.
You are absolutely correct. Yes, they claimed they’re not running Klipper, but I don’t buy it. Given how so many Chinese companies operate with little regard for intellectual property laws, it’s hard to believe they’re entirely above board. The open-source community relies on an honor system, with no real enforcement beyond public shaming—and let’s be honest, when was the last time a Chinese company cared about Western opinions? Remember the Lumber Liquidators scandal?
And don’t forget how Bambu handled the A1 recall. They dodged the word “recall” and called it a “Power Cable Exchange Program” at first and only changed it to “recall” when YouTubers and Reddit called them out. That doesn’t scream transparency.
The truth is, Bambu could easily create a library that plugs into the SB53 utility, just like Bambusource.dll does in Orca. It’s the custom that Josef Prusa has set for the 3D Printing industry. Honestly, I’m surprised Bambu still allows Orca to work on their printers. It would take just one tweak, and every new version of Orca could be shut down. Of course, then they would have to face the backlash from the community whether or not it came from Bambu users or not.
Won’t deny the point about how Chinese companies aren’t shy about using anything anywhere. Are we now claiming all Chinese are bad? I know you’re not. I think overall, Bambu has given us enough signs that we can offer a bit of trust. If you really want to know what open source files they’re using you can ask for them.

I agree they can and should allow use for SB53 utility (not that I’m fully versed on that, but I believe you). Given the willingness to open up for the X1 Plus, who knows.
I don’t remember, off hand, about Lumber Liqudators. I DO love to dive into rabbit holes and scams so I’m on it. However, is what they called it really matter? I mean yes, but no. Everyone knew what was going on, what went on and I have seen many other companies do that ■■■■in my 54 years. NOT that it’s ok and I am not trying to be an apologist, just sayin.
I don’t see your comments as apologetic at all. My views are just one man’s opinion, though many on Reddit seem to share them, where Bambu’s influence is more limited. The Bambulab that once championed openness now seems more focused on self-preservation. The recall issue strikes at the core of corporate behavior.
At 54, you might not recall the 1982 Tylenol poisoning murders, but that incident led Johnson & Johnson to pull all their products in a mandatory recall, even though the issue was confined to Chicago. They lost over $100 million and wouldn’t put the product back on shelves until they introduced new security measures. This response set a standard for corporate responsibility and transparency, lauded in business schools worldwide.
I mentioned Bambu’s handling of the A1 issue to highlight the difference in motivations behind their PR, as their actions reveal their true motives. Yes, they eventually issued a recall, but let’s be candid: the true test of honor isn’t what one does when everyone is watching, but what one does when they don’t have to, simply because it’s the right thing to do. That’s how Bambulab started, but things are changing, and not for the better.
This is why I say it’s a golden opportunity for Bambulab to prove me and others who now have doubts wrong. Believe me, I would love to be proven wrong, but every move they make seems like they’re trying to be more like Google than Apple. That’s not a good look for them. Supporting this small initiative would be a Prusa-like gesture of giving back to the community.
Yes, yes I do remember the Tylenol scare and I curse it everytime I open an over the counter medicine bottle. Selfish I know. I’m going to hop off the recall train because, well you’ll see.
I may be the wrong person for this. I prefer Apple because it’s closed. Ran Android since it was new, and owned the first iPhone. Complete opposite opinion then. Rooted, downloaded nightlies. Grew tired of it and “Just works” was mighty appealing. I dig my BBL because I don’t need to dick around with settings and always chasing the perfect setting for the filamnet/hotend. Man with my bedslinger I would go outside shirtless and do a weird dance while mumbling words like Flow and Z distance.
Almost named my daughter Zeeheight. Was gonna claim it was German.
I can’t explain their actions. I’ll be honest because I just haven’t cared. I get open source and all, and I get some will die on that hill and why they’d choose to do so. I’ll shut up and stand by why some raise the pitchforks and torches. I may even grunt. More power to you, just don’t screw my world up by having me spend an hour adjusting a screw so my print will stick…deal?
At the end of the day I want my stuff to work. I’m 54, lazy, very grumpy, and have a ton of other hobbies I wanna spend time with too.
As always, you do you. Down with the source! I’m really only apapthetic when lives and injustice aren’t at stake.
Peace man!
I was looking for this also. Since the filaments also have suggested temperatures based on speeds. It would be awesome to be able to set those values in filament setting so the printer adapts during a print. Where it adjusts the temperature based on speeds/flow. Ex cool down a little on overhangs and such
I think temperature would be hard to control as its far from instant, especially when heating back up. But it might not cause any visual issues as such, would be cool if someone had the knowledge to make a script that could test it.
or the bad Grinch
