I do not expect that the Mk4 will have caught up to the Bambu in 1 year since it's missing physical hardware that seems necessary to do so. Here are some examples:
Input shaping calibration for a specific machine benefits from having an accelerometer. The Mk4 needs a module that can attach to the extruder and the bed. The current beta firmware with input shaping only allows for Prusa's universal preset setting instead of allowing you to measure the frequency responses of your own machine. Critical reviews of the current input shaping implementation show subpar performance with excessive smoothing and high frequency artifacts. I expect that comes down to inability to calibrate your specific machine and environment.
When you print with a new filament, especially a new manufacturer, you usually need to tune a filament profile to get better printing results. With the Mk4 this is a manual process, and this is where many new to 3d printing quickly get frustrated with failed or poor quality prints. The lidar system on the X1 has been fantastic for automatic pressure advance and flow calibration right out of the box and I've found I largely do not need to maintain custom filament profiles for the Bambu.
Webcam support and failed print detection are absent from the Mk4. The closest feature the Nextruder assembly supports is crash detection via its load cell sensor and I'm not entirely sure if the Mk4 even has that enabled. If you attach a webcam to the frame and run octoprint / something else standalone, you've again thrown off the preset input shaping calibration.
It's an i3 style printer or "bed slinger," which is fine on it's own, but it will never reach the same speeds as core-xy because it's physically moving the mass of your printed object sitting on the bed. Printing speeds aside, you'll potentially run into taller objects wobbling slightly as they are moved.
I really like Prusa's open source commitment, and I'm still in line to purchase a multitool Prusa XL, but I cannot recommend waiting for the Mk4 to improve and reach parity with the Bambu if that's your expectation. If it doesn't do what you want it to do today, I'm not sure it ever will.
As for cloud connectivity on the Bambu, you'll really have to consider just how important that is to you given the significant tradeoffs. Minimally you can print from the sd card or use lan mode. It looks like you currently lose the camera and mobile app connectivity with lan mode, but I haven't tried this myself and these are at least software aspects that could easily improve.
Thank you for the detailed reply. What do you think about the new Bambu P1S? Looks like the main difference to the carbon is no lidar and a worse screen and with the ams addon it's 1000€ vs 1500€ for the carbon. I'm seriously considering getting the P1S.
I've got the P1P (and am waiting for the P1S upgrade kit) and I've got to say I absolutely love it.
I know it's not popular on here because it's proprietary, and a lot of people in this hobby don't like the "It just works" mentality as opposed to the "I custom built this from scratch" outlook, but I got into 3d printing because I want to print things, not because I want to spend loads of time fiddling with my printer. I spend plenty of time fiddling with my various creations and custom models, I just want a printer that I know will reliably print what I'm asking for and use my time and energy on creating things.
I also went back and forth over the X1C over the P1P (The P1S didn't exist when I ordered mine), but from what I understand the differences between the X1C and the P1(P/S) are very incremental. The lidar is nice, and does improve print quality, but having looked at some comparisons, the end-result difference is very minuscule. As for the screen, I honestly don't see why people are so fussed about the smaller screen - I use Bambu Studio for kicking off all my prints, so the only thing I really use the build it screen for is checking up on print times when I don't feel like going up to my PC, or changing filament, and it works fine for those purposes.
Especially now that the P1S offers a high quality enclosure, I think the value add for the X1C doesn't make a ton of sense, You can literally buy 2 P1P's for the cost of a single X1C, and I don't personally feel that the improvements to the X1C justify that price difference unless you really need the absolute highest possible print quality.
Repair-ability is the usual issue most people take with Bambu printers, because it's proprietary - but their replacement parts are super affordable, and I've yet to hear actual testimonial from a Bambu printer owner who had their printer die on them and was unable to get it fixed. The proprietary nature also makes people worried about "what if Bambu goes out of business in a few years", which is valid - but given that they're one of the biggest players in the consumer 3d printing industry after only a short time in the market, I really don't see them going anywhere any time soon
tl;dr - The p1p was my first entry into 3d printing, and the only complaint I've got so far is that the P1S upgrade kit is backordered to August. Otherwise it's been a practically flawless entry into 3d printing
Thanks for the input. I'm mainly worried they rugpull us by doing something like nfc proprietary filament once they have a big enough customer base but the P1S is just killer value compared to any other fdm printer. I commissioned some 3d models this week and have friends who ordered a carbon so I'll probably get a P1S in a couple of weeks (unless the recently trademarked bambu models are even better value).
That'd be pretty unprecedented, and if they did go that route, it could only be for a newer model of printer than anything out today (you'd need new hardware to do the spool check), so you'd be safe regardless
Well they already have a nfc checker in the ams.
Ah, I don't have an AMS, so I didn't know that - either way I really don't think it's likely, but if you're really that concerned, plenty of other options 🤷🏼♂️
The P1S does seem like a good value overall.
I've heard the screen is quite primitive with the P1 printers, and I expect that will become your primary interface with the printer if you are not using the cloud print functionality.
You will also not get the benefit of the automatic calibration features.
For myself that makes it less desirable. However, there is also some value in understanding the manual filament tuning and printer calibration process as it helps you troubleshoot when things go wrong.
If the P1S existed when I was getting into 3D printing, I likely would have purchased it. It's at a similar price point without the AMS to the Ender 3 S1 Pro (which is what I learned on) and the P1 has many more capabilities.
You are talking about the lidar? It can still auto-bed-level without internet right?
Yes, and you will still get automatic bed leveling on the P1 series. I do not believe that requires any cloud connection.
Alright, thank you!
