Cartographer Initialization Issue | VORONDesign | Page 1

It was previously working, but I had a crash and changed extruder to gallileo 2. I took the opportunity to update everything (klipper & co). Sounds like there's a version mismatch

check the cartographer server. there was a breaking change to klipper that renders cartographer inoperable. the fix is listed there.

What do you mean by carto server?

downgrade klipper, or wait for a fix to the cartographer plugin

#

That error you're getting is because you're using the config for the old carto pluging, but are probably using the new pluging. You'll need to update your config

#

E.g. [scanner] stuff is gone in favor of [cartographer], see https://docs.cartographer3d.com/cartographer-probe/installation-and-setup/software-configuration/klipper-setup#configure-klipper

#

As for the breaking change in klipper, don't go past klipper v0.13.0-567 (commit 5557780) and you're fine

terse trellis Mar 5, 2026, 4:11 PM

#

Yea I updated as per the doc

ocean mirage Mar 5, 2026, 4:11 PM

#

Oh, apologies, I should have looked at your printer.cfg. You are using the new config, however at the bottom of your printer.cfg in the "do not edit" section, you still have a [scanner model default] section. Remove all that

#

So remove this entire section:

#*# model_coef = 1.4536755269749384,
#*#       1.8366719398227664,

#*# model_offset = 0.00000
#*# model_mode = scan
#*# model_fw_version = CARTOGRAPHER 5.0.0

#

You will have to recalibrate cartographer after that though

That's a bit weird, as that error originates from the old carto plugin. Do you have both installed now?

#

If you want to get rid of the old plugin, ssh into your raspi; then execute cd klipper/klippy/extras && rm idm.py scanner.py cartopgrapher.py. This will remove the python files belonging to the old plugin. Then restart klippy again

ocean mirage Mar 5, 2026, 4:58 PM

What in the.... that means you don't have the new plugin installed, or accidentally erased it. But not to worry, you can just rerun the install script again to fix that.

You're installing the old plugin again that way 😛

Try following the setup steps from: https://docs.cartographer3d.com/cartographer-probe/installation-and-setup/software-configuration/klipper-setup. This should get you the actual new one and install it for you.

Oh sorry, I made a typo in that. it should be cd klipper/klippy/extras && rm idm.py scanner.py cartographer.py (note the last filename, it's not cartopgrapher.py, but I have fat fingers)

#

Possibly the first two files are already removed and it'll complain about that, but shouldn't be an issue. As long as the old cartographer.py file is removed too (which is where the error originates from)

@ocean mirage
is this fine to ignore?

 Klipper warning

MCU 'cartographer' has deprecated code (it is missing feature 'get_canbus_status'). Recompiling and flashing is recommended (MCU version 'CARTOGRAPHER 5.0.0', host version 'v0.13.0-567-g55577808c-dirty').

deft hare Mar 5, 2026, 6:52 PM

#

is it actually a warning or is it preventing klipper from booting?

#

#1165274914606035047 message this is relevant

ocean mirage Mar 5, 2026, 7:26 PM

#

That's just a warning and can be ignored for now, but for a future klipper version the cartographer firmware will require an update. afaik they're already working on that but no idea when it's due. But as always, the best advice in this is: don't update klipper if your printer is in a perfectly working state. It's not like your desktop or phone OS that needs constant updating 😉
