OK, I'm adequately impressed. My printer arrived a day early. I got it set up, didn't update any firmware, and connected to it as "LAN only." Blocked it from accessing the Internet at my router. Sidebar: When we decided to make the move back to Maine from FL, it was winter up north. I bought the steel wheels and winter tires for my daily driver. I printed up the hub caps and plugs, Plasti-dipped the wheels, put them all together and drove up. On that drive and over the 4-1/2 winters since, I've only lost one plug. They're pressure-fit, and I don't know where I lost it. True to form, my dumb ass printed only the exact number I needed, and not even one extra.​ So, I got the printer all ready to go, and brought up the old STL for the wheel plug. I threw it in the software and hit start. 20 minutes later, I'm holding a plug that fits perfectly. Unfortunately, the only filament I have on hand is the five or so meters of white PLA that came with the printer... so that's what I used. But... wow. Easy. It required no calibration other than the printer did on its own during setup. Awesome.
