I agree! I was pretty bummed when I discovered it was only available with the CM4 if you went with the Pi4b adapter (until now).

nee ting to note is the CB2/Pi 2 doesn't ave an SPI bus and if you are running an ADXL it will not work without an adaptor or switching to a USB accelerometer.

That's what they say. But they also say that it will work with IO2CAN board. And the IO2CAN board uses SPI. So I think that it has SPI and they mean that the BTT PI2 doesn't have an SPI flat ribbon cable connector, which BTT Pi did have.

All versions of the Manta MxP boards (excluding the E3EZ) have an 8-pin SPI header which can be used to connect an ADXL345 board. Pin names are different between the versions but Klipper configuration is pretty straightforward.

Awesome vid! I am planning to use my Pi2 as a home server and discovered this company and product line accidentally. I'm working on improving the support for CB1 and upstreaming some form of support for CB2 in Armbian. Excited to see how the community will grow around the board/module in the future!

Thanks for the video. I just picked up one of these for a new “rebuild” of one of my V1 MP3DP. I run a cb1 with EMMC on another printer and really like it more than the sd card!

Great videos as always!

I like these boards a lot. I have a CB1 in a M8P and a M5P. Both are great. I think they really clean up a builds wiring

This was a fantastic guide, thank you! I managed to snag a Pad7 (w/o the CB1) and a CB2 for pretty cheap and this video was really helpful while I was setting it up.

@@dmmerson awesome! Glad to hear it 😊. Happy printing!!

Thx for a great video.. I battled so much with my Voron 2.4R2 build with Manta M8P and CM4 that I have up and it’s been sitting in my garage 90% complete for almost a year now😫

As I’ve just gotten into 3D printing there is , needless to say, a ton of knowledge which I have yet to acquire. In the three weeks or so that I’ve owned a 3D printer, I’ve your channel is one of three that have become my go to place to learn what it is I’m doing wrong. I purchased an Ender 3 (OG) on eBay for $80 delivered as part of “Brand New, but open box” special. Upon receiving the Ender, i immediately Upgraded the build surface to glass, added second stepper motor and Lead screw to the Z axis and moved to a hardened steel 0.6mm nozzle. All that aside, the issue I’m trying to validate is the fact that it seems to not have enough current to the stepper motors when prints require all of the motors to be commanded on for some of the really long and crazy print moves. It has the stock P.S. and the Creality 4.2.2 board. Is there any way to increase the current availability ? Any thoughts or ideas will be greatly appreciated. Thanks for all the great videos. -Jason Burchell.

Good video mate... As always. Thanks for the sharing. Really appreciate it. Just one thing that I liked as well... That ender 5 turned into merc1. That tool head... Love the small space it has... What is it? Belongs to the merc1 specs or is your own mod? Is there a good kit for merc1 or you did it all by yourself? Thanks for your knowledge share and all the help and contribution to 3d print world!

I got the btt klipper pad last year and I still am having issues getting klipper up and running. It is my first time getting klipper working. I’m going to get it working this summer , hopefully. :)

root and root are always the first thing to try... But thanks for the run through, adequately covered

I ended up using an old phone I had laying around. Complete package with camera, build in led for lighting and touchscreen all in a nice package... Setting it all up is a hassle though, but once I worked out all the funny business it really works fantastic. Although I'm running both the octo4a app (for the serial driver) and a debian vm for klipper and moonraker etc. I'm still planning to port my klipper install to the alpine image octa4a is running to have just 1 app running... But since it's running fine the way it currently is, that's gonna be some rainy sunday in 2030 if ever 😅 I still look to some alternatives like sbc's but it gets expansive fast if you also have to factor in a camera and screen... Can't beat the price of an old phone gathering dust in a drawer somewhere... Heck, it might even make sence to buy a cheap phone second hand if you know what to look for...

Nice to see the RK3566 out there doing more than powering a wave of mid range emulation handhelds. Not enough beef for something crazy like GameCube emulation, but they're reliable little chips. This seems like a great use for them.

13:54 I do prefer running a pi with a separate power supply since the fans on my printer are extremely loud and you need to have everything powered up in order to power the CB1/2, with a separate pi you can do config changes and other maintenance with just the pi running while the printer itself is off and in worst case you can stop a print by just janking the power of the printer (with for example a relay) while mainsail (and crows nest) keep running.

I like it has eMMC, which brings a few perks to the table, especially since smaller builds it can be handy to go with one of these all in one boards like the Manta.

Foot print is definitely a factor for an all in one. I tried the CM4 with the E3EZ on stream a while back and I couldnt get the OS to work correctly. Ended up reverting to CB1.

The one thing I gate about Big Tree Tech is that they always release a new hardware version right after I get the current version. Had I known about the CB2 coming out 2 months ago I would have waited as I just got 2 CB1 modules 2 months ago along with a Manta M5P for the Salad Fork I am build and a Manta M4P for the Enterwire conversion. For me, I don't car tomuch about "Crime Scene Investigation" support (LOL) but I'm sure people that wanted it are happy. Personally i never had any WiFi issues with the CB1. I really, rally hate that antennae connector. I always have issues connecting the antennae to it.

4:03 It's funny how you said the connection could be spotty just as some spots shined over you SuperVinlin

What Quality are you able to run your webcam with the cb2? Because I had heard that was a bit of an issue with the cb1 and was wondering if it is worth upgrading from the cb1 in the Formbot Voron Kit that I might soon buy.

Since you have done a mks skipr, it would be nice to know how they compare.

Hi, I bought the CB1 and realized that on heavy tasks such as input shipping, it really struggles to keep up. The recommended acceleration on the X axis never exceeded 2900/s, whereas when I use klipper on my minipc, I go up to 5500mm/s (I have a Cartesian printer), exactly in the same ADXL test conditions. For this reason, I decided to go for the CB2.

Did you say you got CAN bus working on the CB2? I have not been able to get pass this with the PAD-7. Looking at sending these back to Amazon.

I have a CB1eMMC on a m5p and never had any wifi issues, either I got lucky or the eMMC variant is better…

please do a video on CM1, I was able to get one in uk...

My Voron 2.4 with cb1 is a little laggy with some commands while printing like z offset or pause and usb camera will only run at 12fps but usually runs between 1fps-8fps.would upgrading to CB2 solve these issues.i am using ethernet to printer not WiFi

How does its performance compare against the Pi4/cm4 and pi3b?

hello, I did everything, I have the green LED flashing from time to time but nothing in the IP connection...

I have trouble changing the network details. I’ve even tried copy and pasting the network details from my windows network settings without success 😓

Can I ask what the antenna standard/connector type is for the cb1/cb2? I suspect mine is borked, so while I upgrade to a CB2 for wifi 5 I may as well get a new antenna

The CB2 comes with an antenna as well. (Sorry if I didnt explain that) so you shouldnt need to buy one.

I've upgraded my Ender 3 Pro to an E3EZ motherboard with CB1 almost a year ago. I just learned that I was supposed to add an heatsink?? I don't use my printer that much but so far I've never seen it overheating tho (never hitting above 60°C). Maybe needed only in an enclosure? Or it's surprisingly very sensitive to temperature and I'm slowly killing it (please no)

@bami2

Ай бұрын

Unless you're doing very long prints in an enclosure and cooking the board at 60-70-80 oC for long periods of time you shouldn't have to worry about it. Those heatsinks are mostly useful for very airflow-constrained cases to help a bit with convection but the chip should be able to dissipate most of the heat just by itself. You should however have a fan blowing across the stepper drivers since they have to endure a lot more load, if you do any airflow from that should be plenty to cool the rest of the chips without any heatsinks. Only exception would be maybe if you attached like 2 or 3 cameras and the cb1 has to encode multiple streams, under those kind of loads you'd need a heatsink but mainsail by itself generates barely any load. However adding heatsinks is always a good idea so if you can find the correct sized one I'd still recommend installing it.

Ended up reverting to the CB1. Adxl still won't work though...I may have broken it. Waiting for BTT to release the Pad 7 CB2 heatsink so I can order them together.

I really love the onboard CAN and screw terminal variable voltage power input. Regular Pi power supply requirements are getting insane. With all the auto tech being adopted by 3D printers, I think automotive Ethernet would be the next awesome one. Just 2 wires, much lower latency than regular Ethernet, slightly higher throughput for a given MHz rating and 100baseT1 transceivers are coming down in price.

Ahh you mean going with the BTT Pi or the PI4B adapter with the CM module. Thats a really good point. If your controller doesnt have CAN bridge then its nice to have it and I agree not needing a buck converter or separate PSU is great. Some of the controllers due have the ability to power the PI directly. I have done it at least once or twice but i have heard it can be hit or miss with low voltage issues.

Wait, the label at 0:55 says 2023.11.8 - did they heavily delay this?

Well, you got lucky to make the video after version 1.0.4 was released I got a couple Pi 2s to replace my Orange Pi Zeroes (wifi disconnecting every couple of days was already getting tobñ my nerves, qnd the additional USB ports are a plus), but back then vereion 1.0.3 was out and no CH341 drivers were installed so connecting the printer through USB was not possible (a kind user compiled the drivers to install them on the issue rhat was created, afterwards version 1.0.4 was released with the drivers included...

You say that the new module has 2.4GHz and 5GHz WLAN. So i guess you should use the new antenna they provide, unless the old antenna was already a dual-band antenna. But i doubt they would have shipped a dual band antenna before, with a board that only supports 2.4GHz.

​@@ModBotArmy The antennas provided with my two CB2s are completely different than the ones on my CB1s. They are longer strips. WiFi performance is still not great - it is able to achieve a 390Mbs data link on 5.xGHz out of the theoretically possible 433Mbps using a single RX/TX chain, despite being 2 meters from a 802.11af access point ("WiFi5").. Testing with iperf3 towards a wired server in my network reveals an actual TCP throughput of 120~160Mbps but with a lot of retransmissions. Bottom line - It's better than the CB1 (which wifi chipset was a bad joke), but nowhere near the performance and stability you can observe from a Pi CM4.

I think I'd rather wait for CM5. For better support. I use currently CB1 with armbian because of old kernel in original OS build.

Classic BTT. Never buy v1 of anything they release. wait for v2. CB2 is a prime example of this rule...

I'm using Armbian (Debian 12) minimal on CB1, and the clipper in the docker from mkuf/prind Everything works great. I chose it because it has a new kernel and fresh system software and good support for updates, and docker because I am a developer and I use docker for work tasks and it has proven itself well. I don't use the display, I don't see the point of it when I can go to mainsail on my phone which is always nearby and do what I need or on my computer. I also don't see any wifi stability issues either

The login for the minimal install is root oot fyi =)

Probably not, so really, your only option is the image that comes from BTT. The Rockchips are a little better, but there's generally not very good driver support for Linux on these. BTT has already had a bunch of firmware gaffes that have caused WiFi not to work on some boards, and bad passwords on others. BTT (and most Chinese OEMs when it comes to small ARM SBCs) don't seem to care after the thing ships. Knowing that a Raspberry Pi will get the updates required if an issue arises and that there are quality alternative OS's that can run on it is worth the extra $5-10 for me.
