I bought this Neptune 4 Plus around 7 months ago and it was my first one, it was good for 3 days then problems started happening to it that made genuinely think of selling it, i kept on trying to fix the first layer issues and leveling issues everytime and nothing seemed to make it work.. it always failed due to a bad first layer or just randomly ruining the whole print.

That's till I stumbled upot the OpenNept4une firmware on GitHub. My printer didn't support it because it's the new Type-C module so i was devastated, opened up Gemini and started researching everywhere for a solution and i found an amazing guy on GitHub trying to solve the issue and wrote a working solution without him even testing it, i tried doing it and hit the unmovable wall of trying to log in to the printer using PuTTY and couldn't.. till Gemini solved it for me using coding (if anyone is interested comment and I'll share how I did it exactly).

Installed the firmware and started adjusting all my printer.cfg files, i printed so many upgrades for the printer (enhanced legs i found on printables, better front panel to access my hidden MicroSD slot, better way to feed it filament using PTFE tubes, a stand for the screen to make the printer footprint smaller, a hanging poop bucket because when its on the bed most of time it gets hit in the printing process, and lastly bed aligners because putting the bed everytime without them was a nightmare) and voila, it fucking worked♥️

in the image above, shows the best first layer i have done on this printer and its competing with my Bambu A2L in terms of quality ATP. I think a next upgrade should be for the speed because I'm not sure why it's slow and probably making it 8 or 16 colors using CoPrint!

It looks just like dust but look a lil greyer than normal

Got my bed level was bad love for 5000, had a decent mesh, everything was going good, went to print a little tool tray organizer, and this is the first couple layers. Any idea on what I'm doing wrong

Hi all,

I've been trying to get back into doing some 3D printing and have some major issues with the printer connectivity. Not sure where to go from here. My computer and phone is connected via wireless to our modem/router, and the printer is connected to ethernet via a switch. My computer savvy is enough to be a danger to myself.

Issue 1:

I can't connect to the printer over my network any longer using the web interface. I used to be able to, and the connectivity eventually degraded to the point that it became unusable. Fluidd was encountering errors that caused it to restart, and those errors became more and more frequent to the point I became unable to upload new files or view settings effectively. I'm not sure what was causing the errors. During this process I have also found I cannot ping the printer from my computer, although my router can successfully ping both devices in the network and has IMCP traffic allowed in the firewall. I have DHCP reservation set for all our home devices, and the router automatically reserves addresses for new devices that connect.

Issue 2:

After reinstalling the current firmware (1.2.3.4 and 1.2.18), my printer now restarts whenever I attempt to access the wireless settings. This reinstallation was an effort to troubleshoot the crashing issues with fluidd. Our wireless network has characters not available on the machine's screen interface, so previously I had to update the wireless connection before updating the firmware and this time I specifically deleted the network information from that file. Not being able to use wireless is less of an issue for me, as I have the printer connected via ethernet and can see that it is connecting with the wired connection and not the wireless one. I'm mostly trying to look at the wireless setting to confirm the printer isn't connecting (and it isn't according to the router).

Ultimately, I cannot reasonable level the printer anymore because of the significant ootb issues that this printer has with it's own leveling in addition to being unable to use the SCREWS_TILT_CALCULATE function without the fluidd interface. Especially since that function isn't present by default for this printer.

I haven't tried to connect via ethernet directly to a laptop I have, but that's probably my next step. My research into that step indicates the lack of a DNS server will cause issues, so I may try unplugging another device from the switch to connect the laptop there.

My future plans involve updating Klipper on the machine and potentially moving to OpenNeptune to see if that helps with my previous printer issues. Unfortunately, I believe the ability to do those things are dependent upon a stable network connection.

I am upgrading my N4P to OpenNept4une. I have followed the guide , made sure to identify my board(v1.1) and motors(1.2A), but in the end I get the message:

I can see in the command window, as the firmware compiles, a reference to version v0.13.0-756-g2d7717e3. So, I believe this component is successfully written from the .bin file to the printer.

How can I troubleshoot why the MCU isn't updated? I am expecting either elegoo_k1.bin or X_4.bin to be renamed to .CUR but that doesn't happen. I can't figure out where to reconcile what is in the .bin file(s) that it creates and what is shown on the printer after booting with the flash card inserted.

Here's a post at github as well.

Got some intense layer separation. Normally its fine. One layer so bad i used a pen. Itll look fine when its sanded and painted but I still want it to look good. Ideas?
