  • 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


  • Can you give more context to where the phrasing is used? Coming from a computer science angle, there are different data types for different things. For instance, you would use a “float” (floating point) data type to store a number like 7.12. Likewise, you use an “int” to store a whole number (such as 7). Because computers use a certain number of bits to store information, this means there’s a max size to your data. int data types specifically have a “signed int” option as well as an “unsigned int” (the latter being a non negative integer). The benefit there is that by not storing a sign, the int can store numbers about 2x as large as a signed int.

    If I dont need to ever store a negative value, I might explicitly call out that when writing out an algorithm


  • A prion is just a misfolded protine that has some adverse behavior that your body can’t detect (there’s a mechanism that if your body identifies a malformed protine, it will terminate the cell making it). Anyway, prions live in this small region in a Venn diagram whereits can’t be detected, but can still replicate and cause harm.

    We mostly think of prion diseases (like mad cow) affecting the brain, but I dont think prions are isolated to the brain… Prion deseases happen to involve the brain a lot because a misbehaving protine in your brain will have a lot more apparent effects



  • Highly recommend a soda stream, or soda stream alternative. My go to is 4 or 5 drops of lime juice in a glass, then the carbonated water. Tastes identical to the canned stuff, but way cheaper (and maybe less preservatives? Idk if the canned water has anything besides fruit juice and water)

    I also occasionally like root beer if I’m eating something junky like a pizza slice or burger. I bought a bag in a box of syrup from the small root beer brand I enjoy, and can make my own for a few cents instead of a few bucks per bottle. Plus, I can control the concentration depending on how sweet my sweet tooth is feeling that day





  • Polymaker polyterra. I especially love their army blue and black filament. They print nice and matte, and the colors print almost identical between their different colors. I always thought polymaker was a more expensive brand, but polyterra hits that 20usd/kg for pla price point that hatchbox and other budget filaments used to dominate




  • 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
