Indeed gr5, at times, Windows can slap a super high port number. However, there is a workaround to that as well.
I am posting this in hopes that other users do not get discouraged about printing over USB. I personally believe that is a necessary feature to have, especially when you try to tweak your print settings in order to save some good print profiles in Cura. I like that Cura allows you to save profiles, and that it has soo many print options. However, for those users that do not want to bother themselves with a raspberry pi attached to the 3D printer, USB is a way to go when it comes to tweaking settings.
So let's demystify this high port number value thing that really happens sometimes:
Here's how you fix that:
Get rid of COM ports you don't need. (Unless you live in the '90's :)) ). Than do it by listening to" Backstreet Boys"! :))
Unplug your PC from 3D printer USB port first
1. Start command prompt with Administrative rights (right click run as administrator)
2. Change registry setting by typing: SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
3. Next type: devmgmt.msc
4. Once device manager opens, got to VIEW and check "Show hidden devices"
5. Now look at com ports, you will see a lot of them in transparent icons. Right click and uninstall or delete them. Uninstall is preferred if available.
6. Congrats, now you got rid of drivers you don't need currently.
7. Plug in your 3D printer USB port again, and look at the COM port value you receive.
If COM Port value is still too high here's plan B: In the same Device manager
1. right click the COM port for the 3D printer and select PROPERTIES
2. In "Port Settings" tab, select "Advanced"
3. Look for "COM Port Number" setting, and from the dropdown list, select a lower COM value THAT IS NOT CURRENTLY IN USE by another driver.
4. Click OK and confirm all the way out of all subsequent menus.
5. CONGRATS!!! You lowerred your port number. Now CURA should be happy again.
Ok 3D people. That's all I have for you on this antiquated technology.
Have fun!
