Klipper the Kobra 2 PLUS HW-MOD

Hello guys,

im modding actual my Kobra 2 PLUS!

Hardware is a BigTreeTech Manta M8P v2.0 +CB2 + TMC2209

Here are my first attempts for printer.cfg

https://github.com/crazybanane/Manta-M8P-V2-for-Kobra-2-Plus

There are some Challenges:
If you can`t connect the Board directly to LAN on the first time because you only had wifi then:

-Don´t flash the board first via EMMC!!!!

Create a boot SD Card and setup the system.cfg file with your Wifi informations then follow the Instructions from BTT PDF!!!

Flash CB2 via SD didnt workSpoiler

Hello guys,

(Solution found mor down)

i tried to flash the CB2 via SD Card to EMMC but it wont work. i tried like the description it said but it doesnt show up that i can flash to EMMC it shows only UP Update Bootloader on SD Card.....

What setting i have to made? Theres not enough info about that in the description.

Solution:

Flash the image again on CB2 (EMMC) after flash the Board set another state. The "Loader State" then you can go to Tab "Advanced options" and there on "Erase all"

After this follow the normal instructions in the PDF from BTT

Os it so hard on max to get good first layer? i own only a plus and i didnt had many problems with first layer.

Nozzle´s for Kobra 2´s Good BadDiscussion

Hello,

recently i bought some new Nozzles and for better Choices i changed my Heatbreak too.

I switched to 0.6 nozzles and because of that i print most of the Time PETG i tried some special coated Nozzles.

The first pair that i bought were PTFE Coated nozzles.

After 2 Spools i can say now DONT BUY THESE!

I got Problems with faster Printing very bad Print Quality and many Trash Prints.

The Second Pair of Nozzles are Copper/Nickel coated Nozzles (the silver ones).

After i changed to these it changed the World.

Pretty nice First layers no Bad looks, good Prints and Faster prints were doable.

What are your experiences with nozzles for Kobra 2?

Have a nice Day

Can you give us more Informations about settings you selected?

Get a clean USB Drive and copy the FW 2.1.0 on it. put it to USB with Cam logo on it restart printer and wait a little time. I cant reproduce the problem but can you send me DM with your printer.cfg file that corrupted your FW?

Yeah you can Roleback FW but this isnt a FW issue. You have to Set the Z-Offset new. If you really want to Roleback the Look Here. https://www.reddit.com/r/anycubic/s/eVinE80Ods

Im Not so professionell into this but i think it isnt to hard to Change the Mobo and config it with Klipper. I thought about an Manta M5P Board that should be small enough. The only Thing is that you have to Change many of the Connectors.

Kobra 2 Series SG15 Ball Bearings

Helllo i got problems with my Ball bearings they are dead. Is there someone who knows where i can get some good SG15 Bearings. The bearings on Amazon are sh*t. It would be nice if they where delivered from Europe.

Thanks

looks like something of those:

-too fast

-clogged nozzle

-wrong temps

-extruder too lose

-retraction settings

do you tried to manual heat bed and nozzle?

There are hexagonal screws ON bed an ON the printhead movement.

Question did the printhead move normal when Auto Levelling? IT Sounds Like wrong connection ON the Stepper Motors. Or did you fasten the screws for to tight for Printhead or bed ?
