Got klipper up and running on the new Ender-3 V3 se
Made sure the stock firmware printed the example gcode that came on the SD card and then immediately embarked on my journey to get klipper running on this guy.
I didn't finish until the wee hours this morning so I've yet to really give it a go but all the essentials are operational.
Klipper is sooo much better than Octoprint. It replaced the whole software not just the web interface part. Klipper is absolutely amazing. Now for work, it’s an open source software with community support. So done corporate don’t like not having a company to blame if something goes wrong.
gui is achieved and accessed through mainsail or octoprint. I haven't tried octoprint.
mainsail runs on a raspberry pi and can manage multiple klipper printers with one device. you can also add klipperscreen, it's an addon that can be used with a touchscreen for an interface at the printer (or anywhere really)...
but I just access mine running mainsail through my phone browser or the laptop I use to model and slice. I like orcaslicer because it integrates mainsail right into a tab in the slicer and provides a seamless user experience.
another thing to note... klipper firmware takes the heavy processing typically handled by the printer control board, and offloads the burden onto the computer or device you have hooked up to the printer, processing and feeding the gcode one line at a time. so whatever device you are using needs to be up to the specs. I'm using an rpi 3b+ and have no issues.
