I am able to download/open the .stl files on my laptop but still unable on my workstation. Both are using the updated version of Foxfire and both firewalls where turned off for the test. I have noticed, and do not understand why, that on the workstation the downloaded file ends in .stl.htm extension? It can't be within the browser as CCHSGATE has tried others. Puzzling!

@Herr and @CCHSGATE you both are you downloading from the Website directly, as you go to: https://www.ez-robot.com/Community/Revolution/

Then to the Hix Six Dome: https://www.ez-robot.com/Community/Revolution/EZBitDetails.aspx?guid=30a4fd0d-a026-4c95-8b16-ef372a0e1f68

Then you click on the "Download STL" buttom for the dome and the popup should come up with the option to save the file as a .stl file

When you click the download button you should get a pop up from Windows, clike "Save As" to select the location and so you can view the file name and type:

I have Simplify3D as my default viewer for "Save as Type", but if your computers have something else set it might be trying to save the type as something other than .stl and adding the .html extention, which is why you need to check to see what that is, or change it to "All Files" and make sure ".HTML" does not get appended to your files.

If you clicked on just "Save" then the computer would just save the file using it's own smarts and you would not get the option to see the full file name, set the type or pick the path as you do with "Save As".

Also, have you tried renaming the files you have already downloaded to removing the ".html" appendage so the file ends with just ".stl"?

@ JustinRatliff

This just keeps getting weirder and weirder ... lol. Today I was trying to figure out what could be the problem and Ba Bam, the .stl files downloaded and opened ... ? So I went back to the files I downloaded for the past 2 days (same files) and they still will not open. I did no changes on the computer today for that to happen. You did mention that once the download button is clicked a pop-up box should appear, giving you the option to save the files in a certain extension but that does not happen, either on my workstation or laptop? My problem is fixed now but I have no idea how or why ... lol.

Don't you just love these things called computers ...

Thanks for the help ... at least if someone searches for this same problem in the future, they will have a good read ...

@HerrBall, Yes in deed! I'm glad it is working for you now.

Your browser should always give you the popup to save a file, but if you just click "save" your computer will use it's auto smarts and IF it had some sort of setting or app that thought "Oh these files need to be saved in .html - I'll help you by doing that for you and appending .html to the end - even though I'll screw up the .stl files (hehe)"

I actually remember myself having a problem like once under Windows 8.

But when you select "Save As" you get to see what the file name, extension type and location will be and get to control those incase there is an issue.

@CCHSGATE - how are you doing with the issue?

Whatever the issue was, manually saving the file as a .stl seems to have fixed it. Thanks for the advice!

Computers are a mystery! Always keeping us on our toes

I ran across this article on a Windows 10 bug with file associations, it could explain why Windows may have kept trying to set .stl files to .html files on your computers if you guys are running Windows 10.

I have several Windows 10 computers and support several and I have not ran into this myself, but it fit the problem.
