Got it for my K1 max and it's more of a niche thing, but it's cool to show off. Haven't had any problems with the wifi like I've seen in reviews on other platforms. If you are in to little gadgets I reccomend getting one.

This product is a cute idea in concept, but 2 issues:1 - The official instructions for compiling the firmware with your own issues are incorrect. You WILL BRICK your device. BTT has been made aware on their discord and github but months later still havent fixed anything2. Even once you get the firmware technically working, its unstable. It regularly loses connection (I have a well setup wifi network so I know its not that, pings to the moonraker instance it self never drops) so the animations will often quit working.This feels like something closer to an amateur open source project rather than a sellable product

This is a great offering, full of ports and features that make it a very flexible board. It's capable of driving a variety of 3d printer setups as it is mostly platform-agnostic, so you will probably still have this board when you decide to build your own rig. However, if you are in the market for a simple-as-possible board swap, you may need to continue your research.I've now spent weeks trying to get this feature-rich, affordible board up and running. I've been frustrated by poorly written and supported documentation (obviously, by someone for whom English is not a first language. I don't think editing and review of documentation is a priority for BigtreeTech. The Internet tries to help out, but BTT releases minor revisions without documentation such that you may find some assistance that doesn't apply to your specific model, after you have tried the suggestions.BTT's moto is "for makers, by makers". That is certainly true, but they presume a level of expertise that a newb probably doesn't have. If that's you, make sure you belong to a club, or have a geek who has some experience before you order.Having owned several BTT products, I generally like BTT hardware and find great value in their products. But, their documentation needs help. You don't have to be an EE to read and follow it, but that would help.Lesser mortals have better be prepared to spend lots of time.

I tried this on extruder but on a stealth burner the tolerances are a little tight and I didn't like not being able to see the fan running. I found a Mod that you can install it on the skirt of a voron 2.4. Its not a perfect fit put I made it work with a little extra foam tape. It uses WIFI to talk to the printer board so it can be located anywhere in your wifi coverage to monitor the printer. I think I am going to build a couple of different types of mounts for them because I could see this as a desk widget or just mounted on the printer in a different location.. Its not necessary but it is kind of fun.

Having the Linux host and the printer controller in one board is very convenient. There's also a ton of ports. Highly recommend it.

I gave unit same supply as knomi v1 which still works from same supply point in stealthburner PCB. I fried it neither docs are wrong and knomi V2 can't take 24v or board was faulty either it was crap.

This is the best upgrade on my k1, when I got the K1 I didn't think their would be much I could do with it but I was wrong, I upgraded the hotend to a microswiss hotend and added the D3vil burner hotend from printables in ABS to cover the hotend and added this little informative screen too the tool head and it's amazing, giving me on the fly stats real time on the hotend... I think I now have one of the coolest K1's out there...

I received my Manta m4p yesterdayk, 4.14.23. It's version 2.2. There is zero information on the net for this board? So I'm dead in the water here. Considering that the previous board came with a NON-FUNCTIONING HDMI port, well . . . none of this surprises me now.
