### Basic Information: Printer Model: BLV mgn Cube [klippy (2).log](https://klipper.discourse.group/uploads/short-url/jS9r5sDnrZ3XILSCTKHluqzkB4P.log) (121.6 KB) MCU / Printerboard: Octopus f446 Host / SBC OrangePi klippy.log _Fill out above information and_ _ **in all cases attach your** _ **`klippy.log` _file_** (use zip to compress it, if too big). _Pasting your_ `printer.cfg` _is **not** needed_ _ **Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there** _ ### Describe your issue: Please help, ebb42 is on my head, I bought a cartographer (or rather, a clone from IDM), connected everything according to the instructions [docs.cartographer3d.com](http://docs.cartographer3d.com) but if I connect the cartographer, the printer does not start at all, everything is fine without it, I can’t get the canbus\_uuid of the cartographer either, it gives an error mcu ‘EBBCan’: Unable to connect Once the underlying issue is corrected, use the “FIRMWARE\_RESTART” command to reset the firmware, reload the config, and restart the host software.

Hi Sliver, and welcome. I cannot offer direct help as I do not know enough, but I can direct you a few places… > [@The "dirty" Flag and the Team's Position](https://klipper.discourse.group/t/the-dirty-flag-and-the-teams-position/22753): > > Background Klipper’s main-line code is [published on GitHub](https://github.com/Klipper3d/klipper). Upon start, Klipper checks if the locally installed code is the same as the code published in this official repository. If not, the code is marked as dirty, and a respective notification is placed in the klippy.log. This warning can look like: Git version: 'v0.12.0-439-g1fc6d214-dirty' Untracked files: klippy/extras/autotune\_tmc.py, klippy/extras/gcode\_shell\_command.py, klippy/extras/motor\_constants.py Modified files: klippy/chelper/s… and… > **[Contact](https://cartographer3d.com/pages/contact)** > > The future of 3D printing, The Cartographer Probe.

Though using a clone, not sure they’ll be able to help… Also, consider reading: > [@Cartographer V3/V4: Reverse engineering](https://klipper.discourse.group/t/cartographer-v3-v4-reverse-engineering/25018/12): > > I did try all four combinations and the only one that works for me is the Carto supplied Katapult with Carto supplied Klipper.

Thanks a lot for the direction, I’m going to read, otherwise I don’t have any ideas left, I’ve been struggling with it for the third day… ---

Exactly what hardware did you buy? Is it advertised to be equivalent or did you get bad advice? ---

I had thought about your issue a little more, and while I have no experience utilizing CAN, my gut instinct(from what I’ve read, which I do not fully comprehend) is that maybe the carto clone isn’t properly terminated or in the CAN in the right place. Otherwise maybe flashed incorrectly? If you’re not familiar with this guide, I’ve read only good things, so maybe you can find some help here: > **[Home](https://canbus.esoterical.online/)** > > A guide for setting up CANBus hardware on 3D printers Otherwise if you want to just get back to printing, revert to whatever probe you were using before. While rapid scanning is nifty and all, it’s not that big of a timesaver until you’ve got a bulletproof setup. ---

Thank you all so much for your help and advice!!! After rereading a huge amount of information, I came to a decision… The mapper is flashed in can mode by default and in this mode the bitrate is 1 Mbit, my Octopus and EBB42 were flashed to a bitrate of 0.5Mbit, because of this disagreement, nothing worked, as soon as I flashed the MCU and EBB42 to a bitrate of 1 Mbit, everything worked! ~/klippy-env/bin/python ~/klipper/scripts/canbus\_query.py can0 Found canbus\_uuid=ea18f90fd0ca, Application: Klipper - Cartographer Found canbus\_uuid=aaab58deece6, Application: Klipper - EBB42 ---
