I can say the exact same thing about my P1S and A1mini, and I’ve had them quite a bit longer than the plus 4 has been in existence, plus they do multi color prints with their respective AMS units, something Qidi has accomplished yet.
Honestly, I’ve been printing since DEC of last yr but I am a tinkerer / programmer by night, and an engineer by day. I also am a game developer, so Ive used Blender regularly for the past 10 yrs.
Prob ran through 500 spools to date, Printers run 24/7. Currently updating the eMMc on the Max 3 to run the official KlipperScreen and leave Qidi’s version. Also installing coprint modules/printheads on them
Bambu was my first love but I’m not blind (technically I am on paper lol) so I moved on. That said, my kids will love them, they already do. They call them Toy Machines.
That’s awesome, P1S is a good choice for some, just not for everyone and that’s ok 
Make sure to let us know how the coprint stuff works for you. Also keep an eye out for the next Bambu. I have a feeling it will check more of our boxes.

Pay shills to hype their product?
I don’t remember that.

They ALL (including Bambu) send out bribes to ‘influencers’, that said, I bought every unit I own with my own money.

It’s open-source, anyone can do whatever they want with open-source code, including taking bits and making their own thing. It’s inherent in any open source project that this can, will, and should happen.
The moral grey area Bambu stepped into was using open-source code and then closed-sourcing the result, which they are still allowed to do by the way, anyone can do that. Which I believe they fixed after some warranted backlash. (2nd edit: go do your own research, don’t believe some guy like me on the internet)
Edit: my point still stands on the other stuff though, open-source is designed to be open for others to see, use, change, iterate, etc they haven’t done anything wrong by copying it, it was very evident they copied it (no one was hiding that bambu slicer is forked from prusaslicer) and I do believe they improved on parts of prusaslicer too

Exactly how did they fix this? Can you offer an example?

I don’t have receipts sorry, I thought I had read some reddit comments or something about that they had open sourced some of the parts that were too close to their open source counterparts
I’ve edited my post above to reflect that it’s incorrect, but I have left the original content there so as not to be accused to censoring my narrative
It’s more the point of; what did I miss? Rather than trying to prove someone wrong. I follow the open source discussion regarding 3D printing so this would have been a very thunderous announcement is why I asked.
The three primary areas of source code that would interest users are the slicer, which has been open-source from the beginning; the firmware; and, notably, the communication protocols for LAN mode and the camera. Currently, these protocols are embedded within the bambusource.dll library, which Bambu Lab has announced will be deprecated upon the release of the Bambu Lab Connector. This decision has pissed off many users. One might forgive locking down the firmware of the machine as being part of their “Secret Sauce”. However, having an open-source slicer while locking down connectivity protocols as “trade secrets” may be legal, but it doesn’t seem honorable. It exudes an air of self-serving arrogance, akin to taking one’s bat and ball home if the game isn’t going their way.

I was replying to the person who stated Qidi ripped off Bambu, did you read the comment I was replying to? I
@Olias yeah makes sense, looks like I misunderstood something
I jumped at the terminology “ripping off” more than the whole context
It’s not ripping off if it’s open source is more what I meant, applies to the other commenter as well
Edit: looking at the context I don’t see how the prusaslicer thing relates to what Moodog was saying though… maybe clarify a bit?
I love open source, I am a coder of almost 30 years, but my response was to prove a point to the person throwing Qidi under the bus.

I just had a user ask on my discord (chipp) if they thought buying the Elegoo Centauri Carbon as their first printer was a good idea. Here’s how I responded:
100% would go with Bambu. Start off with a mini with AMS-Lite unless you really need the size. It’s really cheap, works perfectly, and the Bambu Handy app has a bunch of stuff you can start to print with. You can see if you like 3D printing. If you do you can step up to the P1S with AMS (always get the AMS even if you don’t want to print multi-color-- it makes the workflow SO MUCH EASIER!!).
Having 2 printers is also great as often you will want to print something that takes a long time and may want to do some test prints.
The Elegoo Carbon is the company’s first Core-XY 3D printer, marking a significant shift in their product lineup from their earlier Cartesian-style FDM printers, such as the Neptune series, and resin printers like the Mars and Saturn series. There’s no telling the amount of beta testing and fixing you may have to do. Unless you just want to tinker around, I’d stay away from a V1 product like that. Not to mention the Bambu has a significantly better ecosystem. It’s like the difference between Apple iPhone and some random Android-- not just hardware differences but also software and ecosystem differences.

First off, with the current OS license, if you use any of it, you have to OS all derivative code (code that is part of the same source). Bambu Lab used Prusa’s slicer and modified it, just as Prusa did the same with a previous OS slicer.
The issue at the time was Bambu did not immediately create an OS repository for the source code. They said they wanted to clean it up a bit before finally releasing it, which they did fairly quickly. That’s what happened. Very simple and easy to explain and understand-- and all within current Open Source licensing and guidelines.

That’s not fair. There are literally tons of companies that use Open Source this way. In fact there are many addons for Blender (Open Source) that have bridges to code that sits beside the addon that is proprietary-- and no one complains at all. I know-- I’m one of the top Blender Addon developers. There are tons of other examples from other companies that use OS code legally in conjunction with proprietary firmware/software as well.

Monitoring the pressure of ‘molten’ filament at the printer head is a bit tricky as it is fairly elastic. Add that pressure advance is pretty much making an educated guess as to what the pressure will be when the head is accelerating or decelerating which requires a change to the flow rates to smooth out any change.
You could, I suspect, monitor the stress sensors. Material comes out of the nozzle, it’s trying to both push the print bed down and the print head up. If this metric is used as a baseline then a predictive change to the flow rate to maintain a ‘normal’ range is feasible.
It’s not adding any sensors just using what’s there already so the code is already capturing the numbers, it makes it a software exercise rather than hardware so simpler in a way.
More a Space X than a full on NASA solution.

Ah. I was wondering if it used an eddy current sensor of some sort.
I tend to take anything from an ‘influencer’ as being little better than fiction. If they’ve been ‘kindly given or loaned’ an item to review then I give them even less credibility.
Even the maufacturers doing this kind of thing should be suspect, I remember one of the big Japanese companies press fleet of bikes had across the board been ‘specially prepared’ read that as tuned. The press in the UK and Europe halted reviews for a while. I had an enduro bike which it turned out was one of the press pool models from that year, it was noticably better all round than the standard production models.
Not difficult to do with a printer, just custom build it with the best of the parts.
