General Discussion

Use
/dev/serial/by-path/platform-.......

in the printer.cfg

[mcu]
serial: /dev/serial/by-path/platform-.......

complete /dev/serial/by-path/platform-....... with your output

saved and restarted and also restart firmware - same issue. also tried plugging into different usb port and firmware restart

83

this same cable / printer / pi works correctly connecting with octoprint so I dont believe its a hardware issue

84

disconect the usb printer and run again ls /dev/serial/by-path/

85

then your printer has no klipper firmware

86

Not right now, prior to starting on installing Klipper

this should work if there is no communication with the printer it is because the printer does not have a properly functioning klipper firmware.

89

You can see my steps on building and installing the firmware on the printer. When I flash the printer its only about 8 secs between sets of 5 beeps. After install, printer only shows anycubic boot screen. seem correct?

I am able to successfully reflash the Kobra official firmware with no problem. Is it possible to post your firmware.bin? The options are the same, correct?

Now working! Thanks very much @Function3D
Issue was when I copied the text for the files /etc/udev/rules.d/10-usb-serial.rules and /etc/udev/rules.d/98-klipper.rules the CR / LF was lost so the entire text was commented out.

Hey,

First, thanks for the work.

But iā€™ve a question.
does this also work with the ā€œBIGTREETECH Pad 7 With Pre-Installed CB1 Core Board For Running Klipperā€?

Because with the YT tutorials for the Pad 7, some steps are different.

if so, then I want to buy a Pad 7 and use it with the Kobra 2.

EDIT:

I just tested it now.
Simply followed a YOUTUBE tutorial on setting up Pad 7 and then set up the printer from @Crororo
and the Config.

and add the Part to the printer.cfg

Thanks @Crororo and @Sineos for your work.

Hey @Function3D,
I followed your instructions and everything works but the Print speed and Quality are Stock better. Do you know where the Issue could Lay?

93

I donā€™t know what could be happening to you, if you have my same printer and my same printer.cfg then the problem could be in the slicer.

94

So it could be the Slicers Fault, that the speed and the Quality is Slow and bad?

95

You choose the speed in the slicer, bad settings can also ruin the quality

This is awesome thank you so much. For everyone else who is a noob like me here were my mistakes:

Syntax error when typing in commands to putty ā€œprompā€ instead of ā€œpromptā€ā€¦
Grabbed a non-data USB-C cable somehowā€¦
Had to uncomment some things in the config file
Had to change my header gcode in cura sleightly

97

I am using Cura. It seems as though there is some gcode that gets inserted above the header in cura. I canā€™t figure out how to get the SET_PIN PIN=power_ctrl VALUE=1 code at the very top of the code. It starts heating before it runs the gcode headerā€¦ Here is the example.

Has anyone managed to get the Z endstop probe working yet? Itā€™s probably the only thing holding me back from making a total switch. (Iā€™m lazy and also donā€™t like having features attached that I wonā€™t use)

I know that a script exists here to use multiple probes, but I donā€™t have enough knowledge of how Klipper works to alter it, and Iā€™d rather make a clean switch if I can.

Iā€™ve seen some people reporting the bed mesh goes screwy under klipper, has anyone else had that issue themselves?

Getting very fed up with the crippled marlin Anycubic have stuck on the printer, so Iā€™m on the verge of switching.

I picked up a BTT Pad7 and set it up for multiple instances (3 instances). I downloaded the zip that gave me the following 4 files:

common.cfg
macros.cft
slot.cfg
printer.cfg

I discovered some paths referred by these configs are: printer_1_data but my multiple instances set up folders for printer_data, printer_2_data, printer_3_data and also Kobra2_ data

I switched the paths from printer_1_data to printer_data and after correcting my mcu serial port I got connection to my Kobra2. Now Iā€™m getting an error as follows:

GCode path received from Klipper does not match expected location.

Received: ā€˜/home/biqu/printer_data/gcodesā€™
Expected: ā€˜/home/biqu/Kobra2_data/gcodesā€™

Modify the [virtual_sdcard] section Klipperā€™s configuration to correct this error.

[virtual_sdcard]
path: /home/biqu/Kobra2_data/gcodes

If I switch my config file paths from printer_data to Kobra2_data then I no longer get connection. Suggestions?

Does this work for the Kobra 2 max or just the base model? Loved Klipper on my Vyper. Stock firmware on this is meh.
