Information about the "Print via USB" option

[kadirelvan 0]

After starting to print with the "Print via USB" option in the Cura application, the application gave an error after a while. The machine continues typing, but the application is left with a white screen saying it is not responding. Can the printer continue printing? Is it okay if I end the application or if it stays like this? The printing time is 18 hours so I don't want to cancel it.

If it's still printing, leave it.

 

You shouldn't really print via USB anyway - it's mainly a leftover from a long time ago when printers were too stupid to do anything themselves so needed to be fed instructions. You should put your gcode on whatever removable storage format your printer takes (SD card, USB drive, etc.) and print from the printer's control panel if you can.

...or use an application that is specifically made to send commands to the printer via USB such as OctoPrint.

You're a lot better off if you run OctoPrint on a separate device (like a Raspberry Pi, or a really cheap PC) than your main computer. Your main computer is a lot more likely to crash entirely than a separate device dedicated to controlling your printer, regardless of what program you're using to do it.
