CBT Kit Manta M8P V1 + CB1 Start Guide

⚠️

MPX kits stopped shipping with the V1 version of the Manta M8P in late 2023. Proceed with the instructions on this page only if you are absolutely sure that you have the V1 version of the Manta. The process for flashing the currently shipping Manta V2 is described on the Flash M8P V2 and EBB SB2209 page.

Preparing

You need to prepare a USB Type-C cable and have 5V output.

(Recommened USB-Type B to Type C, some PD charger may ouput over 5V via C2C cable, it may burn your M8P)

Strongly recommened to use a USB Wall Charger, some PC USB ports don't have enough power and will cause random issues.

Wiring

Strongly recommened flash them before installed, wire like this

Jumpers: V_USB on M8P, USB_5V on EBB SB, 120R on EBB SB

This pic is made by @Westy_Pity_Da_Fool, it maybe helpful to understand it, notice you need to plug USB cable to EBB SB2209.

Wries:

USB Cable from EBB SB to M8P

Canbus Cable from EBB SB to M8P (canbus 2P connector only)

M8P USB Power Cable

Do not connect the red and black wires, leave them dangling and make sure they do not touch or short circuit each other

Flash CB1

Download the latest image name start with CB1_Debian11_Klipper from github, https://github.com/bigtreetech/CB1/releases (opens in a new tab)

Then use balenaEtcher flash it into your TF card, you don't need to unzip the image.

While flash done, replug the TF card, there have a BOOT partition shown on your PC.

Edit system.cfg and change WIFI setting to yours.

That's all, now just install the TF card to M8P and install CB1 to M8P.

Note: the TF card must install to SOC-CARD, not MCU-CARD

Now power on and wait a few minutes, you should be able to see the CB1 IP address in your router.

Use your browser to visit the IP address shown on your router. The Mainsail web interface should be displayed.

[Optional]Update

Recommened :

Update klipper to latest before start

Set CB1 Can Bridge Bitrate

sudo nano /etc/network/interfaces.d/can0

Change bitrate to 1000000

allow-hotplug can0
iface can0 can static
    bitrate 1000000
    up ifconfig $IFACE txqueuelen 1024

Reboot CB1 by reboot

Flash M8P

cd ~/klipper
make menuconfig

Then set it as this pic

Press Q and save it

make

It would create klipper firmware file out/klipper.bin

Flash it with DFU

Press on BOOT0 and click RESET button

There would be a DFU Mode device found, remember its ID, but normally it's 0483:df11

make flash FLASH_DEVICE=0483:df11

following command:
  make flash FLASH_DEVICE=0483:df11
  OR
  make flash FLASH_DEVICE=1209:beba
 
If attempting to flash via 3.3V serial, then use:
  make serialflash FLASH_DEVICE=0483:df11

if it shows like this, then you have flashed it successfully,

now click RST button to restart M8P (it won't restart CB1)

Check

1.Canboot Check

Double click RST button, the red LED should blink.

cd ~/klipper
python3 lib/canboot/flash_can.py -q

If it shows like this, then Canboot has flashed successfully.

All flash works done, now 4b94c57be78e is your M8P uuid, and 2f0b1ce14660 is toolboard uuid.

Use these replace printer.cfg

Remove v_usb jumper on M8P and usb_5v jumper on EBB SB

Keep 120R jumper
