so this one mounts on the normal rapido mounts ?

Yes, here's the mounting screw layout. It has the same hole pattern as the Rapido.

Thankyou I assume is the rapido uf as in its short

my X rail needed cleaning and re-oiling (I'm no longer greasing my rails - I don't like sticky balls).

Yup, I remember that. I think oil is better as well.

Yes it is. You can fit the extender and then the longer Rapido boot (square type).

You might already know this, but I think it's worth mentioning just to be clear.

This top part gets removed and the mounting holes are under it and is also why there's 6 holes in the hotend @TitusADuxass is showing. Two of the holes is to mount the top cap and the other 4 are used to mount the hotend on a Voron.

Funny... I was just thinking back for a moment about how many different hotends I've had and how the tech has progressed. Dragon, Dragonfly, V6... those were the old-style square block with a heater cartridge and thermistor clamped into holes. Then the 1st gen Rapido with ceramic pipe heater and now the flat Bambu style (for lack of a better term).

I see there are people developing induction coil heaters recently.

That might be the next new hotend heater.

I am still using Slice Engineering Mosquito hotends. Any thoughts on why the Rapido/REVO style hotend is worth the proprietary nozzles, heaters etc.?

Tbh I have no idea I just started with the rapido 2 uhf and well was trying to stay with it but do buy 6 IA becoming a bitter pill to swallow

@sleepster217 Just to let you know - you cannot fit the extender. I tried this morning.

The Aliexpress hotend uses a long nozzle with a threaded length of 16mm. The Rapido extender has a threaded length of only 5mm.

 My experience is almost entirely with Revo; I do have a Prusa Mini+ that started with a standard V6 style hotend, but that's been updated with a Revo.

I like how the Revo is designed overall. The components are modular, so you pick the cold side heat sink that will attach to your print head. The heater is self-contained and easy to swap out; so for example you can now easily switch to a high temp setup with the new 60W heater. The nozzle and heat break are integrated into one piece, so one seam and potential leak point is eliminated. The nozzles really are one hand swap. They are super easy to change out, no tools needed or worrying about proper torque.

The only hiccup is that flow rate isn't as high as some other options. So if that matters it's a consideration.

Thoughts Yes... Facts Nope 

In my opinion, it's mostly about creating some innovation that will gain market acceptance and sales.

As far as performance is concerned. My old V6 and Dragon Hotends would take around 2-3 minutes to heat up from ambient to 240c, the 1st gen Rapido is around 20 seconds and a little bit slower for the new square block style heater in the Rapido 2. The VzBot Goliath is also around the same time to get to temp.

So some might say, so what, who cares how fast they heat-up. Well, heat has to be transferred from the heater block into the filament to melt it, meaning that the faster the filament is pushed into the hotend the faster the heater needs to be to recover the heat loss.

So bottom line... the faster the hotend heats up... the more it can flow. Also, the length of the melt zone is another factor. That's why adding a threaded extension turns a regular HF (high flow) into a UHF (ultra high flow), more mass so less heat loss.

Can u not just fit the shirt v6 nozzles in it with the extension cause I was under the impression that my rapido2 uhf had the option of a long volcano or short v6 but I think with the longs u lost the extension and it became a Hf

I recently installed a Rapido 2 plus on my RatRig. It came with an HF/Short silicone sock, the extender and long silicone sock and 2 V6 nozzles. This is because the extender is designed to use regular length V6 nozzles.

That gives you 2 options...

HF = no extender, short sock and regular V6 nozzle

UHF = extender, long sock and regular V6 nozzle.

There is no long volcano nozzle, you don't use a long nozzle... forget about long nozzles.

I fully agree to the nice design and integration of the Revo hotends. The only reason I would not buy one is I have to buy their nozzles. I dislike propitiatory designs; it's a personal thing

Btw thank you for the comment about the Revo "slow" flow; I did not know that. Just curious, do you know any numbers of the max. flow for a 0.4 nozzle?

Cheers!

Thanks for your comments on Rapido. I will definitely consider a Rapido for the next upgrade, as fast heating and longer heat zone are definitely a desirable property for a hotend. Just, I have spent some time to tweak the CAD drawings to work as good as possible for the LGX Lite/ Mosquito combination for the Stealthburner upgrade and I have these parts already.

Cheers!

Sorry yeah I have the rapido 2f ufh and it cam the same way as yours did as well no I saw some were don't quote me as being right that u could fit the long nozzles

My Revo was 12ish max.

[claudermilk]

E3D publishes 13 for the regular 0.4 and 18 for the HF. 

Like Nero, I want reliable quality parts, not #speedboatraces. I also really like the super easy nozzle swap.

@sleepster217 have you looked at using Bambulab X1C hotend, they're as cheap as chips.

[sleepster217]

So got some more bits in the last couple of days also got a hot end got the triangle labs td6s the one with the long nozzle.

Not sure about it yet like the quality like it looks good just need to see if it is a similar length as the 2f if I take the extension off  as apparently it will affect the offsets when doing a change or option 2 is to put a extension on this one but not sure is it will work is I do that with the option I have

It will be interesting to see how that hotend performs and how well it integrates into the TAP Changer. I forgot you have to purchase multiple hotends so price is definitely a factor.

[NikosSprocket]

Good point @Penatr8tor about all these hotends and extruders.

In that case, a Prusa XL with 5 toolheads and the encloser for $3,950.00 is not overpriced.

Overpriced for my 3d printing budget.

Edited March 17 by NikosSprocket

[sleepster217]

Each hotend is about 140 2 170 for a rapido 2 and 85 for the galileo2 and about 10 for the fans 40 to 50  for the can board in Australian dollars

Well... that's the price to play, right? If you can swing the cost, then it's no big deal.

Fortunately, there's cheap stuff from China, at least for the time being anyway. Even that can get pricy if you buy enough.
