Retired mechanical design engineer also retired from the Marine Corps I use AutoCAD as my primary drafting program I dabble with fusion and inventor I have worked with SolidWorks. My main 3D printers have been Monoprice 15710 or better known duplicator 6. ( Okay Okay broke down bought the Bambu PS1 AMS) I have rewritten the firmware and some of the code to help them print better. I have just purchased the Bambu Lab P1S with a full set of a AMS to run 16 colors. Yes a Sweet printer. I'll kick the one who says it isn't so. 😅😂🤣 That's a joke for those of you with no sense of humor.
