3D printing forums

The PETG is very interesting. I like the UV resistance and that it can be printed semi-transparent, an important property. The temperature settings are lower, that's nice too. That it sticks to glass and breaks it off, yet nothing can be glued to it is hilarious!   I watched this:    The print I'm working on is less than 2 mm high or wide. It's like a flat net that must be lifted from the printer bed and then transferred onto another flat surface. What will be more demanding in the future I can imagine, will be to print adjacently with a 0.2 mm gap, or less, in between (see image below).   It would be amazing if the two prints could be separated later by tearing them apart (without using too much force, that is, e.g, strings). Any idea if this is possible (see 3MF file), or a meaningful aspiration? LOL Thank you! CE5S1_28_array.pair.3mf

Excellent! Many thanks!

Thanks for listening to my rant. Morning woes when I am constantly wanting to love/utilize the program, but not become a pro at clicking notifications, aha.   Anyway thanks for explaining that, and the plugin suggestion. I was going to ask/suggest... if it's not a solvable problem, then at least we can do is "help" it, in an easier way than not. I'll check out the Mesh Tools, sounds nice...   I think I was somewhat aware of the unit/conversion issue, especially regarding STLs and more generic formats. Hrm, please forgive my abrasive questioning then 😉 I guess the simplest idea would be to add two int and string settings in Cura... for 'default scale', and 'default units'. Most of the time I think we're all dealing with the same in each of our projects, as we like to work.    DOWN WITH NOTIFICATIONS! 😉  

That's a pretty good rant.   No CAD programs know anything about "units" in the sense of millimeters, inches, whatever.  A number is simply a number. When you draw a single line and then "offset" or "copy" it over to the side "1.00" away, the CAD app doesn't care if it's 1 nanometer or 1 lightyear.  It just knows that the distance between the two lines is 1.00. A program like Blender may have a standard unit which might be centimeters or feet or millimeters or inches.  Ya just don't know what it does internally or what effect the export utility might have. When you bring a model into Cura and have to scale it to get it to the correct size, then the "scale" that the model was exported at wasn't likely millimeters but something else.  If you happen to end up at standard scales like "2540%" or "3.94% give clues as to what the "units" of the imported model might be.   One of the features of the Cura Mesh Tools plugin is an option for the default scale that models are imported at.  After installing Mesh Tools you can find it under "Extensions / Mesh Tools" and then "Mesh Tools Settings".   As for notifications, I agree there are too many mundane notices but I think there aren't enough informative ones as well.  Some sort of clue as to why my settings won't allow a slice would be good.      

Cool, but can you disable notifications (!) and stop scaling models like it's impossible to figure out unit conversions? Why is it that when I export from BLENDER(!), as a .stl, at "1.0" scale, in millimeters... and then go into Cura... and it can't import it worth any damn? I have to have "scale models" checked in the Cura settings... and then... it will scale the small models... too large (10x) size. Just stop scaling, but import it at the scale it's at! Millimeters... at 1.0 scale. Why is that so hard? Why is it so hard to add an option to 'disable all notifications or warnings'? So annoying.
