Failure is the greatest teacher when it comes to 3D printing. From my first 3D printers, a Monoprice IIIP and Ender 3 Pro to my current Bambu Lab P1S, I have experienced(likely caused) and troubleshooted my share of printer issues. As a public school teacher during the pandemic, I had 10 borrowed printers of every make and model running 24 hours a day printing face shields to donate to doctors and nurses. I am currently a freelance teacher helping students from age 8 to adults learn how to troubleshoot get the most out of this amazing hobby.
