Used to be shown on the E3D website, but that page seems to have been taken down.
Is it officially supported by Bambu Labs? Or is it some kind of unauthorized mod?
It would be nice to have a higher flow rate, especially at 0.6mm and above nozzle diameter.
Maybe you happened to look at that page exactly at the time they changed it? Because I looked at it maybe 8h ago and it was the old normal page (that said sold out), Right now, I’m redirected to Product restock happening on Monday 19th February, watch this space!.
Definitely watching the page.
They’re available now 
(delivery to EU / Germany)
I almost ordered one but then I decided no way there can be a difference matching the price tag. Not with a stock heater. And if I go with an after market 60W or 70W heater, that “high flow design” might not be needed anyway. So for once I will wait and listen…
I saw a youtube video on how it gets installed. For that price you’d think it would be a drop-in, but instead it looked rather janky, having to smear on thermal paste and faf around with a thermistor.
Is it because he got early access, or Is the final release really that crusty?
Plus, that guy on the other thread seems to have cracked how to do it and get even more watts into his after-market hotend, all with very inexpensive nozzles that are easily replaced if ever jammed up.
I dunno, but on the positive side, I’ve got it delivered to me this morning.
I hope they fixed that SNAFU with a thermistor.
They don’t sell it as a complete hotend, so you’d have to physically install the thermistor, heater, and fan by swapping with one of your other hotends or purchasing the parts to install onto it.
From what I’ve read, even though it is nominally a revo, it’s specific to Bambu Lab and not interchangeable with the other revo nozzles on the market. So, no 0.8 or 1.0 nozzles, at least not yet. Hopefully it will evolve to offer that as well.
Meanwhile, maximit seems to have cracked how to get 96w into a hotend on his Bambu Lab printer:
That would be a huge bump above both what we currently have (40w) and what even the Obxidian (60w) can do. Of course, as he points out, it’s not anything officially sanctioned, so there is that. On the other hand, it seems he has taken all the risks already and blazed a trail.
With either approach, though, it would seem you need to go through the effort of developing new print profiles to match their capability. If that’s the case, then the amount of extra work would be the same with either upgrade, which is why I would lean toward the 96w upgrade. If all the profiles were updated in reference to the Obxidian, then that might change my mind.
These are just my top-of-mind thoughts. What do you all think?
A small additional power supply, a FET and a couple of resistors is all it’d take to make something like this work without putting any additional load on the printer’s built in electronics.
Got my 2 today as well. Cant wait to try it.
So i actually measure the heater (aftermarket) and the multimeter shows 52w each, so 104w total. Also i tried going the route of custom profiles but gave up. The flow increase is about 60% so i just run the stock profiles + ludicrous mode 166% and thats a great shortcut. Works great for PLA and ASA etc. I run ludicrous virtually 100% of the time with no problems. TPU and PAHT have to be printed normal speeds.
It’s listed on the product page: You do get the thermal grease, sock, bolts and heater retaining spring (all Bambu OEM) but not only do you need to assemble it yourself, you don’t even get the fan or PTC heater. I think it’s ridiculous for that price. I would want a 60W (or more) heater and a high quality fan included if I’m going to even try an E3D.
A suitable quick-fix indeed, but I wonder how it will actually behave in edge case situations. AFAIK it simply multiplies all speeds with 1.66, likely same as M220 “Set Feedrate Percentage” G-code. But what happens if any of the axes was already near its maximum? Let’s say XY speed was 350 mm/s to begin with. After speedup that would be 581 mm/s but the printer’s max. is 500 mm/s. So how would the Bambu firmware react? Would it, for example:
I’m sure we could find out the answers with some carefully thought out field tests but I assume it would be harder to get them from Bambu, currently.
Thats simply how you install nozzles on the X1 and P1 series currently. It’s 1:1 like the installation of a official new BambuLab Nozzle.
So 500mm/s is the top speed on normal but i do believe on ludicrous mode the travel acceleration speed is bumped from 10k to 20k and the 500mm/s top printing speed is bumped to 830mm/s.
Also some members of my discord dedicated to bambu modding have increased the amp limit sent to the stepper motors through g-code to be able to run 30-40k acceleration! They have made sub 7 minute benchy shaped objects! LOL (for invite link click on my name).
The specified max. acceleration was always 20K so that is not a bump. It could be as simple as the specified 500 mm/s for XY and 30 mm/s E [which corresponds to 72 mm³/s] are meant only as safe/guaranteed limits, and that nothing stops you from exceeding them a lot. I’m quite sure you don’t need to use Ludo mode for that though, that is just a short cut. Anyway that is what I meant with field tests! So yeah I’ll have a look-see in your discord!
I mean every other printer will simply modify the rest of the speeds to respect the axis max speeds in the firmware, it’s been that way for many, many years. I’d be amazed if Bambu isn’t doing the same.
The Obxidian doesn’t have a 60w heater, it uses the stock heater, and e3d have no plans to change that, I already asked them.
Probably, but even so: What actual max speed would the firmware enforce? Is it the 500 mm/s they announce in the specifications, or the 830 mm/s you’d get with Ludicrous mode upon that? Or something else.
