FlowTech™ Hotend for ELEGOO Neptune 4 Plus / 4 Max

This was my first time buying anything from Microswiss, despite knowing about this company for years. I usually went with buying from E3D. I guess E3D must have had better advertising?

Side-Note: I also didn't know Microswiss was an American company. I thought it was in Switzerland, cause, you know, microSWISS. XD

When I went looking to upgrade my stock hotend on my Neptune 4 Max, E3D had nothing to offer. This lead me here to Microswiss where I found this drop-in upgrade. At first I was hesitant, I had read mostly good things about this company, and a good chunk of the "problems" that I would read about were, in opinion, user errors. People not knowing how to properly calibrate and test their printers, or just dropping in a high flow nozzle, cranking the speed up, and then blaming the nozzle for clogs and under extrusion. Anyways, Microswiss had an option for my N4M when no one else did, and I didn't want to (or had time to) go and build a new toolhead so I could use other aftermarket hotends. So, I pulled the trigger on this upgrade along with a 0.6mm Flowtech CHT High-Flow CM2 Nozzle since I was working on a larger project. The new hotend and nozzle arrived a few days later, and the swap was as easy as changing out the stock hotend.

I then got to work running all my calibration prints again, and after tuning my profiles for this new hotend, I have to say, I am kicking myself for not giving Microswiss a shot sooner.

After calibrating, I found that I was able to get the same flow I had with the stock hotend at much lower temps, and the temps I had been using with the stock hotend were now cooking the filament because of the CHT Nozzle. (This is actually a good thing after tuning for it.) This meant the filament was staying in the throat of the nozzle for too long and was heating up much faster, so therefore, I could now print at faster speeds, or at lower temps. I chose to tune my setting for somewhere in the middle, so as to not stress the mechanics of the printer too much since everything else was still stock. Since installing this upgrade, and tuning for it, I have fallen in love with the Flowtech ecosystem. Sure it's simple and not a fancy as the E3D Revo, but that simplicity is actually what makes it so versatile. Plus, Microswiss has options for every printer I own, they're cheaper (but in my opinion just as good as E3D), and they offer free shipping to USA customers.

I have to say that I am very happy with this purchase, and have also gone and ordered the 0.4mm, 0.8mm, and 1.0mm Flowtech CHT High-Flow CM2 Nozzles. I will be back later to look at the Flowtech Bambu X1C and the Creality K1 Max hotends. Congratz Microswiss on 11 years of business, and I am pleased to say that you have gained yourselves another customer. Have a good weekend.

Replacement in Neptune 4 plus was quite easy. New hotend is more consistent in filament flow and results in good adhesion.

No more fustrations with failed prints and wasted time as well as wasted filament.
This is the hotend that should come stand with the Elegoo Neptune Max 4. Elegoo are you listening?
