If you have an Elegoo Neptune 4 series printer and are in the Elegoo Facebook group you may have heard of OpenNept4une by now. If not, you have now. From what I can tell there are two current thoughts about the Elegoo Neptune 4 series printers. One – the printer has a bunch of flaws and just won’t print properly and it is due to Elegoo’s touch of the Klipper software and installing OpenNept4une will resolve all of these issues. Two – the printer is fine and works fine, but you want community Klipper and to be able to update the software without things breaking. You want to be able to add things and be more up to date following the community with its version of Klipper.
I have not had any issues with my Neptune 4 Max for the few months I’ve owned it, I have printed about 20 rolls of PETG so far. But I noticed Elegoo’s Klipper is a few versions behind and they don’t offer updates much. There are a few things I would like to get play with and get working (Spoolman) and I would like to be able to use KIAUH. Plus I like to tinker. With a stock Neptune you cannot update the OS either, which I don’t like. Anyway, I decided to take the OpenNept4une plunge and I documented my process.
The Wiki/install guide on the OpenNept4une GitHub is fantastic. You can head over there and you should be able to follow that guide, it’s a bit more technical so I decided to write up what I did. I have a Neptune 4 Max so all of these instructions here on my blog are for the Max. They may or may not be the same and/or work for other Neptune 4 printers I have no idea. There are probably other steps for other printers, check the Wiki – you have been warned.
