Solved Thinking about switching from Revo to a Dragon or Rapido

[m00dawg]

Resurrecting an old post sorry! Really just wanted to provide a recent update. I ended up switching my 2.4 over to the Revo. That's what I was using on my 0.2 (which was a 0.1 at the time) but one of the wires broke some tens of hours in. I was able to get that replaced but had it sitting on a shelf as I was using a BMO for my V0 and Rapido for my V2.4.

I quite like the Rapido and I think it's honestly built better. However one huge issue I ran into is that it doesn't seem to easily print with HTPLA. I was getting the hardened bulbs much like stock Prusa MK3s (without replacing the heatbreak with a standard E3D one). Swapped in the Revo and so far all those problems went away. This was after doing lots of other things to try and mitigate the issue (including a wicked high RPM fan for the heatbreak).

So just adding this as a word of caution for future searches, if you print lots of HTPLA, the Rapido v1 (can't speak to v2) may not be your best pick. If you're not printing HTPLA though I think it's still great!

Thanks for the update!
It is always nice when additional information is provided.

Yep you're welcome! I figured folks might discover this thread via searching and thought it'd be good to have an update. I dunno if the Revo will be the final form but so far it's having zero issues with the HTPLA (or anything else). Confident enough I may pick up an Obxidian perhaps. Even under normal use I find brass tends to wear more quickly than the nickel/copper nozzles I'm more used to (I really wish E3D would give us that but Obx will have to do for now)

so few years have passed and I am finding this thread because I am comparing my next upgrade. I used revo micro for years and never had a problem until I hit the thermal management problems and started getting thermal creep with some of the models that have slender uprights. this overwhelms the revo micro and all I can do about it is add more of the same model to make the layer times longer. nothing else works. So time to get myself a rapido or a dragon. Dragon is better in its thermal management but rapido has the better name, what to go for on my 2.4 350 cnc aluminium printer? I will not look at slice because the parts are harder to get anyway and many more clones so I cannot tell the woods from the trees anymore.

I ended up settling generally around a Revo plus Orbiter 2 plus XOL. I ran Galileo 2 for a while and it's really nice though I had trouble with the filament I just happened to end up using the most and opted to trade some minor loss in quality for the dual gears of the Orbiter 2. That is a bit of a special use case though and otherwise G2 was really really good and would be my general recommendation for the extruder as the first thing to evaluate. O2 for if you want to print flexibles perhaps or like me have a certain somewhat fickle filament. I haven't tried flexibles with either so that would be worth looking further into but I find the Nextruder (Prusa XL, MK4, and CORE) doesn't do as well with flexibles as compared to the older MK3 extruder, and I believe that's also because of single vs dual drive.

XOL is a bit of a build though I have generally found it worth it. I don't print speed boats all day and in fact tend to print more slowly. XOL let me used Nitehawk 36 and Beacon. This plus a better heatsink fan solution is why I opted to switch as I was getting some heat creep with Stealthburner. Those issues have largely gone away with the current setup.

I did run Dragon for a while and yes it is very good. I'm on Revo now mostly for parity. Originally that was because it was the same across all my printers, but since I've upgraded/replaced my Prusa's the Revo is now only used on all my Vorons. if I swap I'd want to do it across all of them and things largely just work at this point such that I haven't had a real reason to switch.

Not sure if any of that helps your decision, but though I'd offer a bit of an update since I originally posted my initial response just so you can see what I settled on.

I just bought a phaetus rapido 2 uhf.
The revo micro was good but I reached its ceiling and heat creep is a hard one to solve if it is the limit of the thermal management of the system.

It's a good choice. If you still get heat creep, my next suggestion would be to look at XOL

With a rapido 2 uhf it is almost impossible to get heat creep I think. And I don’t normally use existing systems, I like designing my own and I keep them really simple as a rule. Too much going on around the hotend and it gets harder to work on and impossible to see what it is doing. I like open structured toolheads

 

[m00dawg]

You do you! That's the beauty of Voron!
