In my previous thread i short circuited my motherboard. Orderd a new one and hooked it up.
+24V input
CB1 attached
antenna attached to CB1
Sd-card with Klipper
but when turning on the power (for the first time) the 3.3V and 5v leds were OFF.
→ removed the CB1
→ 3.3V and 5V leds were ON. Pretty strange.
this means that my CB1 IS the problem.
I put my old (broken) mother board in (only +24V input) and all leds turned on. This confirms that the CB1 is the problem.
Is it safe to say that my old motherboard is fine? Because if that is true, i can return it.
I need a new CB1 (or other module) i read something about other modules. What other modules are there (maybe newer version of the CB1?) Maybe i can get a better version, that is not that more expensive.
Lot of people don’t like the MKS SKIPR but it has a good 4 core A53 CPU a built-in eMMC for speed and reliability.
Only CB1 and CB2 in eMMC version has it and it’s onboard, you can’t remove and try different firmware saving the main.
And boot from an SD and create an image of the eMMC is a bit tricky.
I like a lot more the SKIPR.
Many other people like to use 32bit MCU with an SBC not integrated. So you can choose their combination. And there are many choices with built-in eMMC or M.2 slot for an SSD.
I am sory but I don’t exaclty what you are trying to tell me. there is something about your sentences that makes it difficult for me to understand.
(English is also not my first language)
Can you elaborate?
You applied power to the Manta M8P V2.0/old CB1 combination and the Manta M8P V2.0 3.3V and 5V LEDs did no light
You removed the CB1, applied power to the Manta M8P V2.0 and the 3.3V and 5V LEDs did turn on.
Is this correct?
If it is, then I would agree with you that the CB1 has a problem - something that is drawing too much power on 5V.
I don’t know where you live, but I would recommend that you look at the Raspberry Pi CM4 - the BTT CB1 is a form factor copy of it. The CM4 has a bit more computing power and is well designed and built (Not to say the CB1 isn’t, just that Raspberry Pi products are the gold standard). It also has the DSI and CAM/CSI ports properly wired (the CB1 doesn’t).
I’m saying that I don’t know where you live because it can be difficult/expensive to get Raspberry Pi products in some countries. Definitely don’t order one of AliExpress - they’re at least double there than from authorized distributors.
You can also consider the BTT CB2 - A bit more expensive than the CB1 (around the same price as the CM4) but has more computing power and DSI/CSI properly wired.

I live in The Netherlands. i can buy a CM4 from a German site for about €34
Is the installation very different/ more difficult compared to the CB1?
The best replacement would be the RPi CM4. Then, you can run the unmodified/unaltered full versions of RPi OS, Klipper, Moonraker, and your choice of add-ons that fully work with the GPIO connector and many hats. One I am using is a dual FDCAN bus adapter.
The short answer is, you won’t have any issues running with 1GB of DDR and no eMMc.
If you want to have the eMMc to load the OS, Klipper and GCode files, then you need to get one with at least 16GB and probably 32GB would be optimal. This really raises the cost and you won’t see any difference in operation.
If you do go CM4
Use the Raspberry Pi Imager
Set up all the options, username/password, Wifi SSID and password, and enable SSH, with the RPi imager
Select the Bullseye Lite version; Bookworm is the latest but probably more buggy.
After you get access to ssh login
Install KIAUH
Use kiauh to install Klipper and Moonraker and choose your WebUI. After you get back up, you can install other additions.
