  • Its just a test to dial your printer in. I shimmed my bed with 0.1mm washers. I haven’t done a full square of plastic, but I printed my first layer / z-offset print of choice in all 4 corners and center in order to verify the bed level results in octoprint were accurate.

    Before hand 70% of my bed printed perfect, but one spot was a little lower, and the mesh bed leveling wasn’t accounting enough for it. Parts printed on textured sheets would not pick up the texture as well in that one spot. I like the textured look for top surfaces of control panels and such, so having an area on the bed that wouldn’t apply the texture was a bit annoying.

    Tests like what you are talking about is an extreme way to verify that everything is square, or at least well accounted for in the firmware.

    Also, since this wasn’t something achievable out of the box until recently, printer manufacturers are showing it off as a point of pride / as a sales tactic.






  • I run freeipa internally, which handles all internal https certs (as well as nice things like handling non sudo auth so I can just ssh to machines from an already authed machine without a PW prompt, and doing ldaps for internal things that support it)

    For external web, I have a single box running nginx as a reverse proxy thats web exposed. That nginx box has letsencrypt certs for the public web stuff. The nginx rp has the internal CA on it and will validate the internal https certs (no mullet SSL here!)

    I also do different domains for internal vs external, but thats not a requirement for a setup like this




  • I like to create things. For me, its a nice feedback loop of positive feeling throughout the process.

    I get to learn new skills in order to complete the thing I’m trying to make. At the end of the day, I get to feel good that I learned something new.

    I get to work with my hands and throughout the process, I get to see the progress I have made. At the end of the week, I get to hold the thing as its coming along and feel good about the progress I’m making.

    At the end of the month / few months when I’m done with the build, I get to feel accomplished as I have overcome the challenges along the way, and I have a finished “thing”

    For the foreseeable time after, each time I use the thing I made, I get a little boost of positivity, because I get to think to myself “yeah! I made this!”

    It also allows me to be social by sharing the thing I have made with other makers online, or I can help them with their projects by sharing knowledge I have accumulated.





  • Yep, as others have said, valetudo. I have a z10 pro and love it. I highly recommend one with an auto empty dust bin… Having to clean it after every run defeats the purpose of an automated vac. if you forget to empty it, it will be very ineffective the next run.

    Also, I would say make sure you can assign a room for it to clean. If you have cats, automating it to clean the litter box room after they go is soooo nice


  • Old PC that can be on all the time.

    If you dont have one and want dedicated hardware, I would recommend a used server, or something you can whitebox (like using as asrock rack mobo that takes a desktop ryzen but supports ecc memory)

    Put proxmox on as the host OS, two ssd’s in raid 1 is good for a boot drive / VM storage drive. Raid 10 if you want real high performance, but probably unneeded.

    Look for a case that has a SAS backplane, and then connect the backplane to a HBA card. Pass this card through to freenas for storage shares and stuff.

    I recommend not virtualizing your router. So, if you want togoet away from Soho gear, either flash a Soho router with openWRT, or build a separate box for pfsense or opnsense. If you go that route, you will need a separate switch / access point. Unifi gear has a good balance of features and affordability, and can all be managed from a single ui (let’s say you have 3 switches and 2 access points… You dont need to go to 5 web UI’s, its all in one spot - and you can self host the web ui in proxmox)
