  • Ah, I didn’t actually look at the Aoostar device you mentioned in your post… yeah you probably don’t want to run TrueNAS on that, something lighter would be more appropriate.

    I do want to point out that in this price range you can get a used PowerEdge tower that will be more capable, reliable, repairable and upgradeable long-term. You can add more drives, more RAM, and even a second processor as your needs grow, plus it has a proper backplane with a physical RAID controller and redundant PSUs. If any of the electronics in that R1N100 fail you have to replace the whole device.

    Of course it’s a lot bulkier, so it might not fit your use.


  • My priorities are ease of installation and administration, as well as reliability.

    How much of a priority is reliability? How many drives are you running, and how many of them are mirrored or hot spares? or are you running one of the striped RAID levels?

    Hard drives are consumables and should be expected to fail. Data redundancy is a fundamental requirement for reliability. Probably everything else in the server is disposable/replaceable, but the data isn’t.

    TrueNAS makes management of mirrored drive pools easy, and frankly 1:1 mirroring is the most sane way to handle redundancy (vs. parity striping), and you should always have at least one hot spare in the pool as well. For instance, I have five 8TB drives in a TrueNAS server - two mirrored pairs, and the fifth is a hot spare. I have 40TB of drive space but only 16TB of storage, but when an active drive fails then TrueNAS will automatically bring the hot spare online and copy the data from the mirror of the failed drive onto it and alert me that a replacement drive is needed. This is easy to set up, and TrueNAS also automates SMART testing and will attempt to load balance read & write cycles based on drive age and performance.
















  • In the current market, you want a printer that runs Klipper. The system will typically include a web application that controls the printer (Fluidd, Mainsail, or Octoprint) running on an embedded RPi. You just access this through your browser, it’s not necessary to install anything on your PC.

    You will need to install a slicer software. The slicer is sort of the equivalent of a document editor - it’s how you prepare the 3D file for printing. Your printer manufacturer will probably recommend or distribute a particular slicer, but the file format used for 3D printing (G-code) is an open standard published by NIST. Any slicer software can be used to output gcode for printing - you can use whatever you feel comfortable with.

    Personally I reccomend Orca Slicer or SuperSlicer but there are many options.

    By the way, the entire market of home 3D printers grew out of the RepRap project that started 20 years ago. The original project was open hardware and software, and so almost all of the software in use today is open because open source principles were the foundation of all of it. There are some companies in the field who keep their stuff proprietary, but frankly I avoid their products and consider them to be anathema to the 3D printing community.
