Klipper looks interesting. Im still running an old old Octoprint build on a pi because it works and dont wannna deal with it. How does it improve the print vs just sending gcode? My main pc is whats slicing and dicing and creating the gcode. How is the Klipper improving that?

All 3d printers make translations based upon things like bed level, etc. Supposedly klipper is able to adjust for things like ringing or ghosting as well, where the frame wobbles a bit after the head moves. I'm sure there's others, but that strikes me as the most important one at the moment.

  Indeed, Klipper can work with an accelerometer and cancel out harmonic resonance in the printer. It is the killer feature of Klipper IMO — along with a configuration that is dirt simple (no compiling C and flashing firmware). Of note of course is that some of this is theoretically possible via OctoPrint as well.

    RRF supports both of those features, but hasn't been ported to many devices. With how hard Raspberry Pis are to get now, being able to run everything off the microcontroller is nice. There was a time we used RRF's DWC as an interface for Klipper too: https://github.com/Stephan3/dwc2-for-klipper-socket https://github.com/Stephan3/dwc2-for-klipper-socket

Quote from a klipper's benefits page I found [1] "Klipper uses the extra computing power and built-in algorithms to better calculate step movement times for motor actions, achieving movement precision of 25 microseconds or lower. Scheduling movements with an external computer also allows your machine to can carry out more actions in a given period." It ends up meaning quicker, better quality prints. Input shaping and resonance compensation make a world of difference when printing quickly. I also have a bltouch on my ender3; I found the bed leveling procedure with the bltouch to be way easier and more precise with Klipper. 1. https://www.3dprintingbuff.com/what-are-the-benefits-of-klipper/ https://www.3dprintingbuff.com/what-are-the-benefits-of-klip...

The improvements are mostly higher quality prints, especially when printing fast. It also has a much better and more powerful configuration system. So for example if you want to edit the menu on the screen of the printer, you can, and it doesn't require a recompile.
