My brand new Prusa Core One … feelings

Yes, I’ve owned a Core One for a few days now. I’ve run several MK3 and MK3S printers over the past 7 years, and the feeling grew stronger: I needed something new! The printer arrived 2 weeks earlier than promised by Prusa. I ordered it factory-assembled.

Why the Core One?

To be honest, I was looking at a Voron. And no, I wasn’t even considering that walled-garden stuff called Bamboo… However, the Core One had all I wanted to have, and Prusa got quite some Credit in their account. Open-source features, good prints out of the box, responsive support, and a vibrant community. And yes, it comes for a price!

My tales …

After it arrived, I unpacked the monstrosity (heavy weight …), ran through calibration, did a test print, and then the problems started… one after another. I’m listing them here, including the solutions—if I found one. No solution means the issue is still there…

How to secure your Octoprint installation

The community of makers using 3D printers is growing. So does the community of Octoprint users. Of course these users want to access their printers interface from remote.

The ISC was mentioning lots of insecure Octoprint installation in one of their posts. 

In return there was another blog post at Octoprint.org telling about more or less secure practices to gain remote access to Octoprint installations. Here is my take on this.

The mentioned blog post tell about how insecure it is to just open a port for forwarding on your router. Do never forget: once you enable the port forwarding, your Octoprint installation is visible to the world, and bad guys could possibly hijack your installation, and turn your heatbed and nozzle to „5 million degrees“, burn your house, and more. So it might be a good idea to add some security to our installation.
