BGCode install

[IanAdd]

Running octoprint on a Pi.
It has worked well for a few years talking to a Prusa Mk3S+.
I've just upgraded the Prusa to Mk3.5 where Prusaslicer delivers BGCode.
So, I select your BGCode plugin to install. It says successfully installed at end but does not show up in the plugin list.

I reran the install, same problem, here is the log,
I am running octoprint 1.9.3

Any suggestions?

try installing zlib with the following command in SSH and then reinstall the plugin.

sudo apt install zlib-dev

[jneilliii]

The other option is just to disable the bgcode format from the slicer completely and not use that format. you don't gain anything from it with OctoPrint.

[skardach]

I believe the issue might be here: https://github.com/jneilliii/libbgcode/blob/main/CMakeLists.txt#L120

Apparently version argument has to be on the second argument to find_package as shown here: https://cmake.org/cmake/help/latest/command/find_package.html#basic-signature. In the issue I linked they mention CMake 3.26 as the version that started enforcing this.

Interestingly enough on Alpine linux chroot used for octo4a if one does not install cmake, this issue will pop-up (perhaps python's wheel installs cmake into a temporary location?). Once I installed Cmake (packaged version is 3.24.4), this error went away.

When I revert prusaslicer to gcode from bgcode I see that prusalink, should I decide to ask it to print instead of octoprint, does not draw the picture of the object being printed, so I'd like to use bgcode for that reason alone at this stage.

[jneilliii]

Embedded thumbnails in gcode doesn't work with the new firmware? My Slicer Thumbnails plugin can extract those from the gcode file on upload to OctoPrint. If your slicer is configured for OctoPrint instead of PrusaLink you should be able to send directly to OctoPrint, but I don't understand the first part of your statement.

If I drop a gcode file into prusalink it does not show the image, if i drop a bgcode one in it does show the image. See screenshot. Both come from prusaslicer set to print on a prusa Mk3.5

I wonder if these instructions might help you....extracted from #11 (comment)

sudo apt install git
sudo apt install zlib1g
sudo apt install zlib1g-dev
sudo apt install build-essential

Hi, I had the same issue, upgrading from an old install of octoprint when upgrading from a Prusa MK3s+ to a Mk3.9.
To resolve I SSH'd in and ran these commands (I hadn't updated for 18months!):
sudo apt update
sudo apt upgrade -y
then restarted the raspberrypi and re-installed BGCODE from within octoprint and it worked fine, although it does take a bout 15 minutes so be patient.

@Flatstrap , thanks for the tip but it didn't help.
Did update & upgrade, rebooted
Attempt install BGcode from UI and slightly different error list due to OS updates, I guess ....

I didn't make the underlying package, PrusaResearch did. Whatever build dependencies that are necessary for building it from their repo should give you a hint as to what you might need to install the plugin successfully. The one that seems to stand out is missing zlib-dev. So you could try sudo apt install zlib-dev and see if that helps, otherwise see how to build the underlying library and all it's dependencies from here.

On Debian, Ubuntu etc, it's zlib1g-dev 🙂.

Would you be open to upload the plugin to PyPI, in case even with pre-compiled wheels? I could help with GitHub Actions workflows to do this either triggered, or automatically when a new release is tagged.
