Wondering if anyone on here has tried it and what's their opinion on it Link

I'm not sure why you'd do that now that 32 bit boards are getting pretty cheap. It made sense a year or two ago. Not so much now.

You do know it is meant to run on a 32 but system right?

Yup. Its meant to run on something like a RPi and control another board with actual stepper drivers. I considered it for my cr10, but went with a duet wifi instead. These days there are $20-30 32bit boards that have integrated steppers driver slots. What I was saying is that Klipper made sense when low cost 32 bit integrated boards didn't exist, or were high cost. Now days you're better off putting the money you'd spend on a r-pi for clipper on a dedicated board. To be fair I haven't looked at it in great detail for awhile and maybe it'll run directly on stepper integrated boards now. Just why that over reprap or marlin, I'm not sure.

I am wondering what this software is used for.

Clipper is kinda a hack to get a faster 32 bit chip to run your printer. 3d printers move in small increments called steps. If you want to printer faster you need higher step rates. If you want to print smoother, you need smaller steps, which means you need higher step rates generally. 32 bit solves a lot of this. It can run your existing steppers by offloading all the processing to a raspberry pi, etc. It can't actually change the number of steps the old driver can do, but it can run it faster or interpolate the signal so that it looks less like a stair step and more like a smooth curve. Some implementations can completely replace the drivers as well, which is where you see the most improvement. Some printers like Deltas need better CPUs in general as the calculations to drive the printer are just a lot more complex.

Also 3d printer boards tend to have very little memory and slow CPUs so running something like clipper can enable a lot more advanced printer features. Things like a Web UI, resumes, fine printer controls, etc. My melzi board on my cr10 couldn't even handle many more TEXT menus that the printer was fully cabable of doing, just the control board sucked that much.
