Neptune 4 Pro 3d Printer

[Adele Strecker]

Myfirst 3d Printer is an Elegoo Neptune 4 Pro. I got it which I got knowing it doesn't have WiFi, but it does have the Ethernet connector and it's in the same room as my computer. I'm printing just fine using a thumb drive. That is, I load .STL into Cura, set up, slice, save to a removable drive (the thumb drive) and march it over to the printer, select the file and print. Works fine, but too many steps.

I wanted to use Ethernet to send my print jobs to the printer direct from Cura. So I looked up how to connect this printer to the network. Pretty simple: Cable from router to printer, reset the printer, check its IP address from the screen, then type that IP address in a browser. What I see is Fluidd (Klipper's front end) and I can monitor print jobs as they progress.

Approach 2) Same steps, then click "Add printer by IP address" > Enter IP Address > Add. It spends 5 seconds saying "The printer at this address has not responced yet." which changes to "Could not connect to device."

I have the same printer and can see the issue you have. I do not think that Cura supports sending prints remotely to a Klipper 3D printer. What you can do is send prints to the printer through the Fluidd interface. You can do this by selecting the jobs tab on the left and then clicking upload and print in that menu. This will allow you to select a .gcode file from your computer and send it to your printer wherever you are. I attached an image showing you how to get there from Fluidd.

...that Cura should be able to send the same gcode file, byte-for-byte, to the printer via the network. If it can't, that's weird. Cura has a cool Monitor tab, which I'd love to be able to use, and I know Fluidd has something similar, but only with a top-down view.

UltiMaker Cura is first and for most designed for working with UltiMaker 3d printers.

This is why something for a 3rd party product might feel like a "work around" or require a plugin as noted by ahoeben.

UltiMaker strives to add compatibility and functionality for 3rd party 3d printers.

I am brand new and just learning. I have a Neptune 4 Max printer and when I was trying to set up cura, I couldn't find this printer in the drop down list of printers to add. I can see other neptune printers up to the 3 but none of the Neptune 4 printers. However, I see in the forums people are using Neptune 4 printers with Cura. It seems like the slicer would need to know my specific model to accurately slice things for me to make, right? So I figured I couldn't just use a different printer.

Sure

I get the printing bed leveled using the method the manufacture states. I can print using the USB card and the prints come out perfect. (Well as perfect as they can using melted plastic...)

When I tie in the OCTOPI and print using it, the Z-axis goes off. (See picture for one of them.)

It's like whenever I start the OCTOPRINT, wherever the head is, it assumes as HOME.

I had the head halfway up and tried using it... The Z-axis home was where I started it, not where the limit switches tell it to be.

I am assuming this is something in setup that I need to change... Perhaps it's sending a code to the printer when I connect that is wrong?

OctoPrint starts to communicate and and the printer reacts with nothing.

And then the printer requires line 1 again. Line 1 has not been send yet, just line 0.

OctoPrint resends line 0 and the printer says: ok.

And the the printer immediately replies with Error: Wrong checksum.

You may check the USB cable, maybe try this: Put tape on the 5V pin - Why and how , you also may have a look on your firmware.

There maybe could be a slight possibility, that there is a fault on the printer board.

There are loads of budget 3D printer options on the market. You can easily find cheap 3D printers, but sourcing one of the best 3D printers under $500 can be a challenge. Enter the Elegoo Neptune 3D printer, a quality device for makers of all skill levels. Learn why this may be the top entry-level 3D printer you can buy in my Elegoo Neptune 3D printer review!

From manufacturer Elegoo comes the Neptune 3D printer. It's a Prusa i3 size printer that boasts compatibility with PLA, ABS, and TPU filament. There's a carbine glass build platform and Titan extruder. Whereas many 3D printers come fully assembled, the Elegoo Neptune does require a bit of assembly. However, I was able to get my Elegoo Neptune configured in a jiffy.

Pros:

Like the Elegoo Arduino UNO starter kit, I was truly wowed by the Elegoo Neptune. A layer height of 50-300 microns allows for quality as well as speed. Essentially, layer height is the precise height of each layer of plastic in a 3D printed model. You'll find variable speed, smoothness, as well as resolution with different layer heights. Smaller heights range from around 50-100 microns, so its range of 50-300 is quite pleasing, especially for a budget printer.

Upon opening the box, I was greeted with a mostly assembled 3D printer. As a semi-assembled 3D printer, I had everything I needed to put the Elegoo Neptune together. First, you'll need to screw the bed in with four screws, then plug in three plugs. You'll find loads of accessories including a backup nozzle, tweezers, and even a bit of sample filament. You'll definitely want to snag a bit more filament for projects though. Installation took me about 15 minutes, 10 of which were reading through the sparse but completely comprehensive set up pamphlet. There's even a section on leveling your 3D printer, and steps on how to run your first print.

Unfortunately, leveling isn't the most enjoyable experience. How to level a 3D printer depends on what 3D printer you're using. Whereas some mid- to high-end 3D printers use software leveling, or even tout self-leveling, the Elegoo Neptune is a manual leveling get up. Typically, manual leveling a 3D printer requires thumbscrews. The number of screws depends on the printer, with as many as four screws. Sure enough, the Elegoo Neptune features four screws, one in each corner. Under the system menu, there's a leveling setting which checks five different points on the bed. What you'll want to do is place an A4 sheet of paper on the bed, then, test each point. It's best to keep the sheet of paper so that you can slide it out with a minimal amount of resistance. Too tight and no filament will stick to the bed. But too lose means your print job will come out sloppy.

Since leveling requires adjusting four screws, it's a bit of a challenge. With more adjustment points comes near constant fiddling to get your bed correct. My first test print failed miserably, a result of user error and not properly leveling my print bed. But my second attempt, a basic disc-shaped object, yielded a highly detailed finished piece.

The print resume feature is an excellent inclusion. This way, if you run out of filament while printing, you can merely resume printing once you power back on. I was able to proceed from unboxing a semi-assembled 3D printer to cranking out 3D printed objects in under an hour. I appreciated the USB and SD card connectivity. There's an SD card, complete with flash drive adapter, in the box. Onboard, you'll find software and drivers as well as a test file. Of course, you can always source your own 3D printed projects and send those to your Elegoo Neptune. I preferred merely transferring files to the included SD card and printing from the Neptune.

While the Elegoo Neptune doesn't come fully assembled, it's not a complete do-it-yourself job. Instead, it's a semi-assembly kit which is conducive to getting up and running. I was able to cobble my Elegoo Neptune together in under 30 minutes.

A convenient feature onboard the Elegoo Neptune 3D printer, you'll find a filament detection switch. Further, its print resume capability means if you run out during a print job, it automatically picks up from where it left off upon loading new filament.

Elegoo Neptune 3D printer specs:

If you're in the market for one a budget 3D printer, the Elegoo Neptune is a top choice. With excellent build quality, superb printing, and a slew of features found on higher-end devices, it's a 3D printer sure to wow makers of all skill levels. Beginners should have no issue actually assembling the device.

My only minor complaint is that leveling the Neptune remains a pain. Still, once it's properly leveled, the Neptune provides high-quality prints, and easily clocks in as the best cheap 3D printer you can buy. Quality of printed objects surpasses the Anet A8. In fact, it punches way above its weight class. Lack of features such as software leveling may leave power users wanting, though it's a fantastic printer overall. If you're looking for inspiration, try printing your own Arduino-based coin sorting machine or an Arduino-controlled, 3D printable BB8!
