Rapido All Metal Hotend (Blue, UHF)

The media could not be loaded.  Have put a few prints through this so far it it's worked flawlessly. Assemble was cake. Will probably put it in all my 3D printers going forward

Awesome hotend used on my Voron 2.4r2 300x300 with Stealthburner. I opted not to get the UHF Ultra Hiflow because it's longer and puts the nozzle too far below the fan ducts. This works with the official Voron Rapido Stealburner mount without modification. The connectors did not match the ones on my build (Formbot Kit w/ Dragon HF) so I had to cut, crimp and replace with ones that works. Of course your mileage will vary but if you built you printer with a Formbot kit... be aware that it's not just plug in and go. I've been running this with a Diamondback .4mm nozzle. Now flow issues printing at speeds up to 300mm/s but mostly I print around 150mm/s.

Installed quickly and started printing beautifully right out of the gate. I need to design some tests to experiment with how high I can get the flow, but so far, it's very promising.Love that it came with a volcano adapter so I can use my cheap volcano nozzles or my expensive CHTs. Nozzle changes are super easy, too.

Understandable not a seller fault, the Rapido UHF came working as intended and was simple to install. All accessories were included too.The problem lies within the heater, I was PID tuning the hotend for the install and the ceramic heater core failed open. The resistance shot up to 300 MOmhs which sounds the ceramic failed when heating up for the first time. Verified that my system was 24V and could supply adequate power, simply stopped heating after 2 minutes of use. Now I am well outside the return window due to waiting for parts to ship internationally that were required for the install and down another $50 in replacement parts.I don’t see a way to contact the seller regarding the issue, hence the low rating. But I will re-assess the rating given overall customer experience if they are willing to work with me regarding the problem.Flawed product, nothing wrong with the seller so far. Rapido 2.0 solves this issue so go for that instead.

I purchased 2 of these for my Vorons. BOTH have had jams and filament broken off and stuck in the hot end.Great purchase if you like throwing money away. Maybe you would have better luck with the V2 version. But shame on Phaetus, this hot end is garbage!!!

My mistake was not buying this hotend way sooner! It is absolutely fantastic and easily the best hotend I have used. Highly recommend it.

Very good seller and the product is amazing it prints amazing quality at high speeds. Had many issues with other cheaper model that get clogged instantly when printing pla but this hot end handles all filaments amazing.

Update 3/23/22: Seller responded quickly and is working to get me a replacement heater cartridge. Great customer service and easy to work with!The strain relief did not have any slack in the wires going to the heater cartridge, and the wire assembly is fragile as a result.I would just buy a replacement heater cartridge, but nobody sells them. I don't need the nozzles, socks, hardware or heatsink. Just a heater/thermistor cartridge.Kind of a bummer, as it was decent while it worked (even though it hit nowhere near 75 cubic mm/s flowrate, closer to ~50 or so at quite high temperatures (top of the range recommended by the filament manufacturer).

The hotend heat really fast and the filament flow is really good. At first I was using a regular extruder and had clogging issues. I decided to change to a dual gear extruder and everything work like a charm.The downside is, the first time I've disassembled the hotend to unclog, one of the three small screw broke in the socket. The other two are okay but this one is stuck there and I can either replace it (can't find these type of screw) nor remove it since it's kind of deep in the screw socket.I've printed since with only two screw attached. For small print, everything is fine... but for higher print, there is over-extrusion on the side opposite to the missing screw. It's seems that I can't equally adjust this section of the hotend and create a small angle that cause this problem.Anyone have any idea how I can replace/fix this part?
