I'm sorry that you had trouble getting the script to work. The obs-zoom-to-mouse.lua script itself is written in pure lua with no external dependencies (unless you count lua FFI but that comes built into OBS) and it doesn't use any python at all so I'm not sure why you needed to install anything extra.
Yes, currently the script can only work against one source at a time, and the source-clone creates a new one which is separate to the original.
Oh, I just noticed this.
In the latest script (maybe you need to download it again) there is an option to "Allow any zoom source". If you enable that, you should be able to select non-display capture sources from the zoom source drop down.
What does OBS show for the properties of your display-capture source? It's possible the script is calculating the wrong size for the monitor.
That's weird, it must be calculating the bounds of the display incorrectly. What does OBS show for the properties of your display-capture source?
Thanks for the reply I think I figured it out. So I use (2) 2560 x 1440 monitors and a vertical 1080x1920 monitor. The Center Monitor Is set as the Primary Display. If I Make the Left Monitor the Primary everything works like a charm. Doing some checking with the Bar Raider Move Window plugin To Check how windows sees the Transform, it Sees the Left monitor top left as x = -2560 and y as 0. Currently the script only allows positive integers for X offset. May be worth implementing, but it's likely a edge case. Thanks again for the awesome plugin
Not sure if it is a bug or just my settings, or maybe what I'm trying to achieve is simply not possible :D

crop.x = math.floor(clamp(-500, (zoom.source_size.width - new_size.width) + 500, crop.x))
crop.y = math.floor(clamp(-200, (zoom.source_size.height - new_size.height) + 200, crop.y))I can see the problem you are describing in the videos (in that the mouse isn't always visible in the zoom area even though it should be).
I think this is a limitation of how the script tries to stay within the bounds of the display, it doesn't account for really wide/high sources that go outside of the canvas (or something like that)
I'll need more time to be able to figure out a good way to calculate what those bounds are supposed to be (especially because I don't have a really wide monitor, awww).
As a really quick work around, you could delete lines 607 and 608 (assuming you are using the latest version of the script):
obs-zoom-to-mouse/obs-zoom-to-mouse.lua at main · BlankSourceCode/obs-zoom-to-mouse
An OBS lua script to zoom a display-capture source to focus on the mouse - BlankSourceCode/obs-zoom-to-mouse
If you remove those lines it won't try to clamp the coordinates so you should see the mouse go all the way to the edge. Unfortunately, it will show a black area when it goes too far rather than stopping at the edge. Try it and reload the script to see what I mean.
You could also try modifying the lines instead of deleting them to add an offset to the clamp, for example:
Lua:crop.x = math.floor(clamp(-500, (zoom.source_size.width - new_size.width) + 500, crop.x)) crop.y = math.floor(clamp(-200, (zoom.source_size.height - new_size.height) + 200, crop.y))
Here I've adjusted the x and y min/max values by 500 and 200 respectively. You'd need to play around a bit with the values to find the correct ones for your monitor. I'm sure there is some way to calculate what it should be, but I can't quite figure that out at the moment.
Hope that helps.
crop.x = math.floor(clamp(-640, (zoom.source_size.width - new_size.width) + 640, crop.x))
crop.y = math.floor(clamp(0, (zoom.source_size.height - new_size.height), crop.y))
