I want to experiment with Klipper and I had a Monoprice Mini Delta going unused. So I thought I would give it a try. However I am not going the easy route. I happened to have on hand an Odroid XU4 and I installed Ubuntu 20.04 server on it.
My first hurdle was to install Octo and that was interesting since 20.04 defaults to python3 only support. However I found good news that Octo has just switched to python3 moving forward. I pulled the latest code and it seems to work just fine.
Next I pulled the Klipper repo and found the python3 branch. I merged with the latest from master and made a few fixes and was able to build the firmware and run with Octo.
I could create a few pull requests if you are going to consider moving to python3 soon.
I might also be able to help put together the configuration and scripts necessary to build a Debian package. That would make it easier for people to install and update Klipper on most Debian based platforms. Would you be interested?
