I have twelve 3D printers and I bought my first machine, an Ultimaker 1, in 2011. I managed fine without it but every advancement that means less fiddling is a huge quality of life improvement that I always strongly prefer. I got ABL for the first time by modding it in to a printer I had. I then modded it in to my other printers, and now would never consider or recommend a printer without ABL unless someone is very broke and can only afford the cheapest Ender 3. The Prusa Mk4 improves upon older automated bed leveling techniques by using a load cell in the nozzle itself to measure exactly where the nozzle touches the bed, rather than using a sensor near the nozzle which then requires manual height calibration. I have five Prusa Mk3s but I really want the Mk4 in large part for that. I am so bleeping tired of fiddling with my 3D printers, I just want them to work.
