I am a NOOB to 3D printing. Since I have retired I have a lot of time on my hands and have a robotics project I am working on. I thought I could use the printers (4) to make my custom parts. I was very active and loved hunting, fishing and camping but a failed back surgery which has damaged my leg functionality, has put an end to those hobbies so this is my new one. My luck with the printers is not good, only get four or five prints before something goes haywire not sticking, warping, etc. Then I find out after I have dismantled them trying to update them to fix them, that I have to calibrate all movements on the printers. So I now have a Creality CR-10S Pro, Tronxy-XY-2-Pro, Anycubic Vyper, and Creality Ender 3 Pro in various stages or disassembly. They make upgrades look so easy on YouTube!
