  • Take out any spinning rust and pack those in a foam HDD case. Number them as you pull them for easy reinstall.

    Put a bit of plywood under the rack, ratchet strap it, and now you can put it on a dolly without the lip hitting the equipment as you try and lift it. For avoiding it falling off the dolly, use a 2nd ratchet strap and wrap it around the chassis / dolly.

    Put a 2nd piece of plywood on top once its in the uhaul so you can load more boxes on top… Maybe even do that at first so the initial strap is securing it as well.

    As for the bottom plywood, if you add some felt pads, then it will help you shimmy the chassis into / out of its position once its unloaded. I have my rack vhb taped to ply with felt under it and recommend it to people IRL a fair bit.








  • 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




  • 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
