Hi, This is John w/3DPrinterOS. I also felt the same way years ago with online banking and the potential security issues, but the reality is -- life is much easier when you do things in the cloud. Of course many people do not setup their printers correctly and the cloud can not help there, but once you learn to setup your printer properly with the right setting, right filament, and maintain it properly -- The next challenge is accessibility and time. Having access from anywhere, anytime provides a lot of hidden value with running multiple print jobs from the cloud. You should try it out.
