Started at the beginning of the pandemic with the purchase of an Ender 3 Pro, quickly upgraded to home-made direct-drive and an all-metal hotend, later added a TwoTrees Sapphire Plus core-xy, again converted to direct-drive and then upgraded both to Klipper. As third printer - after long hesitation as I like tinkering - I finally ordered a P1S and so far I'm blown away by it. And yes: it helps print parts for my other 2 printers and for itself ;-)
