I am a retired Programmer and Analyst and generalist in web programming and C/C++ . I’m also qualified and experienced as an Communications Electronics Technician. I got into 3D printing whilst engaged on an electronics project. That was over 18 months ago, and I have not looked back. Over a period of 6 months in 2022 I worked on my MMu, which was giving me a lot of problems. I experienced first hand most of the issues encountered by others. Unlike others I wrote down my analysis of the issues in a 30 page report and sent them to Prusa, making a strong case for upgrading its design. No doubt this added weight to reports from other users and prusa support staff.
