Gotta say, it's nice to see someone posting videos on the N4 Pro. I've got one and appreciate you putting these out. Keep it up!

See a lot of my childhood scattered around your desk, please keep the videos coming so I can share with my kids as you seem to be a great example of an intelligent and articulate young man. Thanks for the content!

I just got the Neptune 3 Pro a few months ago and wanted to swap nozzles. This is the only video that I could find that shows how. Thank you for this. The N3P print head is exactly the same style if not the exact same head.
As a side note, I also took the plastic housing off mine which has the 2 side fans. This allowed me to clean them out as some dust webs were starting to form. Do this before heating up the nozzle. It only involves removing 2 small hex screws then pulling the power plugs from each side fan. The wrenches came with my printer to do this.

Most helpful video about this- because the other video (by Elegoo I believe) showed the extruder had to be taken apart (remove the cover and fans). This video was the simplest and straight to the point. And thanks, I did what you showed and changed my nozzle (was printing all sorts of things almost 24-7 for months now).

Easy, straightforward video. Just what I was looking for. Thanks.

Awesome video Ben! I haven't replaced my stock nozzle yet, but when/if i do, I'm definitely re-watching your video, thanks!

I didn’t know about how moving the servos too fast can damage the motherboard. I have a N3P but I’m glad I clicked on this video. I’ve been troubleshooting my mobo that broke after I was moving it around

I bought my Neptune 4 Pro about three weeks ago, and was wondering what it was going to take to change the nozzle.
This is so much easier than my Neptune 2 or any one of my past printers.
Thanks so much for the tip!
Your new sub, Buck

Hey dude, 100th comment. This really helped, was quick and easy to understand. Thank you so much! You did great!

Nice. Just ordered some new .2 and .6 nozzles and your demonstration is super helpful for someone who hasn't changed any nozzle.

[AtomDellow]

Thanks for giving the details on the tightness of the nozzle when torquing.
This helped a lot, I wasn't sure if there was a piece I had to take a part within the assembly (there is a brass stem the comes out from the heatblock, which is why I came here.
To see that you can just take it off from it being still connected and on, was surprising. I thought I was going to have to take a heatgun to it.

Hey Ben, great video! Appreciate you walking us through this!

Hey, Ben. I watched your report on the Neptune 4 after run in time. Very unbiased, informative, and well presented. I'll be watching the out two shortly. I think I'm leaning towards that printer. Oh, and 73

Thanks mate, my first nozzle change on any printer and it helped! Have a great day.

[jamesherr]

Nice tutorial. I like your no-nonsense approach

[TheEightshot]

Really appreciate this video, thankyou very much for taking the time.

[PeakDecline]

Appreciate the video and getting straight to the point.

[ZekeTrimmer]

Just a clarification because my friend made this mistake, make sure you dont put the pliers on the thermistor, located on the upper right hand of the hotend block, you are likely to shatter the ceramic that holds it on and you will get thermal runaway

[klaasbloem]

Thanks Ben, this was a great help for my first nozzle change!

For cooling down I activated the parts cooler in Fluidd 😀

Thank You very much. I was looking for a tutorial. It’s my first 3D Printer and I want to make things right. 😅 I also wish a happy new year. 🎉 Regards
