I just loaded 2.6.2 and when I started the application (windows 10 OS) I added my printer (I3 Clone from Geeetech) I can not find any place to enter the com port and baud rate for the printer. The software says that the printer is not connected. How do I get the software to see the printer? I had no issue using the software on a previous version. Am I relegated to saving the file to a SD Card?

    In a word: Yes.

    Or you could print from another host, such as PrintRun or even legacy Cura.

    If Cura 2 does not see your printer, there is no way to get it to at the moment. Printing over USB has fallen off the radar for Ultimaker. It might return in a future version of Cura, if a community member or another printer company contributes fixes to Cura.

    There's currently a PR that you could help test. Please try replacing the file plugins/USBPrinting/USBPrinterOutputDeviceManager.py (NB: that file should already exist!) with the following file, and let us know if it makes any change for you:

    I did replace the text in the USBPrinterOutputDeviceManager.py file as requested. I assume that this change would allow me to configure the USB com port and/or allow the application to see my printer. This change did not make any difference. The application says it can not connect to my printer.

    The changes in USBPrinterOutputDeviceManager.py only potentially improve the detection of printers, they do not add UI changes. Unfortunately the changes do not improve the situation with your particular printer. In this case, I can't help, yet.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
