Windows 10 "Opening Serial Port" issues.


Recommended Posts

Posted (edited) · Windows 10 "Opening Serial Port" issues.


We bundle our printer with the older Cura 15.04.6 and a lot of our Windows 10 users are reporting issues connecting to the printer. They say they are getting stuck at "opening serial port" window and are never able to successfully connect to the printer.

Some users were able to fix this problem after downloading and installing Arduino separately to make sure the drivers are installed. But for some this "fix" doesn't work.

Any suggestions on what may be causing this issue? Any help appreciated!

Our board is using smoothieware.

    This sounds like a driver issue -- have your users remove Arduino drivers and have them re-install the latest Arduino software from the proper website.

    For some users, running setup on Admin mode may be needed, as well as a restart between uninstall and install.

    Make sure your users are running latest Windows 10 version since there are some known issues with older Serial drivers.

    If you can physically access client computers, grab an Arduino Uno or a Leonardo to test if you can upload the Blink sketch with the Arduino IDE.
