This post outlines the steps I needed to get Let's Encrypt to work on a Synology device that has been upgraded to DSM 7 and is not accessible from the public internet.

If you have hosting service or domain name registration through GoDaddy, you can use it in place of an external Dynamic DNS service. Similar processes can be used for other vendors, but GoDaddy is used in this example.

A NEW VERSION IS HERE!!! One of the really nice features of OctoPrint is the ability to easily get time-lapse videos of the print. Duet makes an awesome product but by moving away from OctoPrint you lose the built-in ability to create a time-lapse video - this is how I overcame that!

Cloud-hosted UniFi Controllers, or any UniFi controller exposed to the public Internet for that matter, should be as secure as possible. If you follow Crosstalk Solutions guide for hosted UniFi controllers you may want to follow these steps to further secure your installation.

Filament runout is a serious issue in 3d printing. There are add-on runout sensors that you can buy but for a couple of dollars, you can print your own! You already have a printer and the first things everyone prints, after the calibration cube and tugboat of course, are printer upgrades; what are you waiting for?

One of the really nice features of OctoPrint was the timelapse video option. While Duet boards, in my opinion, are much nicer than Marlin based boards I really do miss the option of timelapse video that OctoPrint provided. This is the second major revision of a process to automatically create timelapse videos from Duet printers.

So, you think you want to get into the world of Information Technology huh? How about a few words from someone that has been in the field for 15+ years.

Your Ubiquiti UniFi Controller is probably already set to make automatic backups. Why not copy them off the server automatically for safekeeping in the event of a hardware failure?

Back in the day, FTP was THE way to publish web content. Now I prefer SSHFS and it looks like I am working on my local computer!

Use Visual Studio Code and SSH to work directly on your remote systems. Much easier and faster than FTP, SSHFS, SCP, etc.!

Labeling cables might run a close second to cable management. Especially if you have a lot of hard wired devices connected to your network.
