BIGTREETECH CB2 Core Control Board 2GB LPDDR4+32GB eMMC Storage Upgrade on BTT CB1 Support DSI/CSI Port Run Klipper Compatible with Raspberry-Pi 3B/4B Manta M8P/M5P/M4P/E3EZ Pi4B PAD 7 3D Printer Part

Absolutely love this board. Incredibly versatile, incredibly powerful. I have this set up with a CB1 and 2209s, everything works great. The manual does a good job at pretty much covering everything, albeit, not phrased the best. Nonetheless, super flexible board for endless possibilities. Love all of the fan controls, stepper driver options, UART mode, DIAG for sensorless, USB, ethernet, etc etc. It truly covers everything for a potentially awesome and big build. I see some reviews talking about "I thought this would include grub screws", or "Doesn't run the printer on USBC power", and - cmon people, it's a controller board. It includes JST connectors, which I wasn't expecting, so that's awesome. And USB C power? I understand a laptop, but you're running 24v heaters and motors, controller, etc, how would this work over USBC? There's no where they mention you can RUN this board with USBC. Like people, do a little digging! Yes, you can use USBC to program and config, it won't power fans, motors, heaters, etc, it's enough power to program things before setting things up. And that makes sense. Regardless, great board, I've been very excited about using it, and it's been fine configuring and optimizing things for my build. New found love for BigTreeTech

This is a great upgrade from the CB1. While I haven’t tested it with webcam decoding/encoding, it logically outperforms the CB1. I’ve have it running on a BTT Manta EZ3D, and it runs smoothly without issues. The GitHub page for the Kllipper image is actively maintained, which is a big plus—thanks to BTT for keeping the community supported!

Not easy at all. Cannot get to work. Returning

I recently reviewed this item but couldn’t figure out how to find/edit that review. I was having problems connecting via WiFi. I have since resolved the issue. The problem was unrelated to the CB2. It is functioning well now.

Unfortunately, these boards are junk if you need more than one USB peripheral, even with a powered USB hub. I build a lot of printers and normally use Octopus and Octopus Pro boards. I took a chance on this Manta with a CB2 without realizing the board only has two USB 2.0 ports, and trying to use a Beacon Probe and a USB camera overwhelms the limited USB bus causing MCU timeouts, despite increasing TRSYNC_TIMEOUT. External Raspberry Pi's also CANNOT be used with the Manta M8P as the USB port to connect to the MCU is hardwired to the CB1/CB2/CM4 interface. I will salvage the CB2 and use it to upgrade a BTT Pad 7. The Manta M8P is going in the trash, it has wasted far too much of my valuable time.

Running Klipper along with Manta M8P on a custom 3D printer. Works nicely so far. I will get another one for my new printer project as well.

have these on 3 Ender3 Pros, love the upgraded interface, makes working with the printer much easier

Unlocks an easier upgrade path to dual z and a heated bed as well as a bigger power supply

The BIGTREETECH Manta M8P V2.0 has been an excellent controller for my 3D printer. I paired it with the BIGTREETECH CB1, and together, they’ve worked flawlessly. Setup in Klipper was straightforward, and the whole system was up and running with minimal effort. The performance has been outstanding, with smooth operation and reliable results on every print. If you’re looking for a powerful, easy-to-configure controller for your 3D printer, this combo is a fantastic choice!

Instale el kit en una ENDER 3 PRO, y funciona muy bien, "plug n play", es fácil de instalar y la calidad es muy buena.

Buena bonita y barata, me gusta mucho como esta funcionando, es muy fácil de instalar Klipper, y lo recomiendo 100% mucho mas facil de configurar que Marlin y la impresión es mejor en todos los sentidos

This board is not for the feint hearted. Be prepared to do some tinkering to get this working properly. Instructions were not great online, but I managed to hook everything up properly using a pic I took of the stock Mega Zero connections. Not sure if this is default but the board I got was already flashed with a firmware that had the heated bed enabled which my Mega Zero does not have. This required me to grab the firmware from git and flash that. Also something odd, when plugged into via USB port, the board seems to get powered on even with the switch turned off and displays "TMC Connection Error". This means that leaving this hooked up to a RPi running OctoPrint will not work. After some research, somebody on the forum came up with brilliant idea of taping up the 5V trace on the USB connector which blocks power from going to the board via USB without affecting data. Overall, the product is good but requires a bit of fudging to get working. Pros: - makes the stepper motors almost silent - the firmware is based on quite a recent version of Marlin - adds additional features that original Mega Zero doesn't have ie. BLTouch, heated bed, etc Cons: - instructions and wiring diagrams are not very clear - required some taping up USB 5V connection to get it play nice with RPi w/ OctoPrint - required firmware flash out of the box to disable heated bed

This board is absolutely insane as far as I/O goes. Support for 8 steppers, 4 hotends plus a heatbed, dedicated motor and heatbed power inputs - it's an absolute monstrosity and was a pleasure to work with. I integrated it in a custom portable 3D printer, where it worked flawlessly; I supplied it with +12V for the main power input, and +24V for the heatbed and steppers. Overall, getting Klipper set up and running was trivially easy. I'm knocking a star off for the documentation regarding the CANBUS, though - which is nonexistent. I bought a BigTreeTech Eddy sensor (from the same company) to use on the toolhead over CAN, but could not for the life of me get the CAN interface working. I eventually had to use a third-party guide, since the provided documentation on GitHub doesn't cover it at all. Additionally, the CAN-H and CAN-L pins were backwards compared to the schematic, which cost me several hours of banging my head against a proverbial brick wall. With that being said, I don't know if they are flipped on the Eddy's documentation, or on the M8P's - so I'm not deducting a star for that.
