So, what the new Pro series allows us to do that the current N2/N2+ can't?

The main feature I see is the moving nozzles for dual extrusion. I'm sure the feature works, I'm sure the test users who got one had a great time (I was not a tester). Without more technical details, without actually seeing first hand how this is implemented, without putting it in the hands of the novice who I swear can break anything, making the mechanism more complicated than already as seen in current versions- I see a ripe disaster and some very pissed off users in the future. It's like the ideal mechanism. It works just long enough a reviewer likely to get one on loan will never see the frustrating- what if you do want to change a nozzle situation. To them it works like magic- all the way until it stops working and then the frustration factor will fully kick in. If you cannot change a nozzle now, if you cannot level 2 nozzles if your life depended on it, a nozzle that also moves- just think about that for a second.




My first thoughts are:
While I like the new upgrades, there are 2 sides to this coin, existing owners and then new buyers. How I feel about it matters for both groups, but in slightly different ways.

Example 1, moving to a 32 bit motion control is generally a good thing. Upgrading stepper drivers is generally a good thing. That said, there are a few questions:
What firmware specifically is now running on the 32 bit motion control, and if it's just marlin ported to 32 bit- my enthusiasm drops significantly.
What specific stepper drivers were chosen? Are they soldered on the board with zero chance of upgrade? If they are TMC2130s, that's not really an upgrade compared to the newer TMC22xx series with Stealthochop 2. Further, who's to say in 6 months something better doesn't come along. Point being, soldered on drivers might be good for tech support- but limits the "Pro" user.
Also, we cannot forget that the system has not changed. Gcode is still streamed over a USB to serial logical data channel. There are still all the existing rate limitations. I'm just saying, moving to 32 bit in a standard Cartesian printer has limited gain, if you couple that with just porting over existing Marlin firmware, it's not exactly a ground breaking earth shattering upgrade. Again, read this for what it is. This is an upgrade, but how you may view it as a user, what it really means, what it will change in actual real world daily use side by side compared to an existing N series printer is not expected to be earth shattering to the point you should feel your current system is inferior, In fact, your current printer right now today can slap in TMC2224 stepper drivers for $10 each and likely be a better driver unless that's exactly what they chose.

Example 2 is the moving nozzle system. Face the facts, they can say whatever in marketing, we've seen claims before. Yes, I believe the repeatability of the nozzle position is that accurate. Sure, why not? It's just one number. The part that is not yet proven is that given just a single week of typical posts in this group- how do you expect a user to change a nozzle and not destroy the hotend or leak? It's a more complicated system, reusing the existing hotends, you still logically would have to mount and level both nozzles, we cannot get users to do that now. Maybe I'm wrong, maybe this is the new miracle of a century, but I walk away with a lot more questions than answers. Truth is, marketing at the Prosumer, they don't want you to change a nozzle, they want you to change a hotend or pay for a service.
I'm not doubting the new system does what is claimed or it's not that many of you think this is a good idea. But there is a gap between user skill and daily usage and required repair replacement on a more complicated mechanism that is not accounted for in these wish list features.

Filament detectors- already an upgrade and we've said this before, a bone simple system with limited detection features. If as rendered it's at the extruder- did anybody even think about how long pause (buffered gcode segments and those could be long segments) executes? This is why it's a bit too late if the detector is only mm above the actual drive gears of the extruder. Yes, small short segment prints use small short segments of filament- so if that's all you tested with- you think it works fine.

Heated bed upgrades- good. But, like everything else, some words and a picture VS actual production shipping and real world usage, you are hedging a bet on marketing. Again, the features sound nice, but until a couple hundred novice and pro users use this- we see how production quality is maintained, it's not a selling point I'm banking on, nor is it something I'm just dying to retrofit into my already working N series printers.

Optical endstops. If you managed to crash and damage a mechanical switch endstop, then logic says the same user is perfectly capable of bending the optical flag and crashing one of these. Accuracy never came into question in the first place, so this change, while good, is again not a game changer IMO. It's just different, not good or bad. If you really want, it's not hard or expensive to retrofit your existing, but if that was the case, why is that not a more popular topic?

Bondtech extruders- definitely a good upgrade. But again, for existing users, we already have this option and it doesn't require buying a new printer. On the other hand, how angry are some of you at tech support for claiming you voided warranty or they won't help if you upgrade, and yet in the back room, the company was switching to Bondtech anyway.

Again, my take is that for a new user considering this printer, yes, the upgrades sound great. If you are an existing owner, this does not mean your printer just became obsolete overnight.



Thanks for the analysis. I was trying to decide between the N2 and N2+. Now, I have to also consider the Pro2/Pro2+. The price for the Pro2+ is too high. Unless there is a list of good reasons, I am not going to buy it. Are there reasons to choose the Pro2 than the similarly priced N2+ or the N2?

There was a list of filaments that are compatible with the N2/N2+. I cannot find it anymore to compare with the new list of materials for the Pro2 series.

The Pro2 is mostly an evolution of the original N2. There are no differences in what materials you can print; since the temperature ranges are the same. The most significant benefit of the Pro2 over the N2 (in my opinion) is the retracting hot ends. The BondTech extruder is a definite improvement over the original N2 extruder; but you can order the upgrade kit directly from Bondtech for $200.00. It is fairly simple to install. (Just be certain to view both the video and read the instructions; then be prepared to use a little intuition. The instructions are a bit out of date; as the extruder now comes fully assembled and you can remove the original extruder as a full assembly; without taking individual components off - such as the stepper motors.) A little advanced prep and examination of all of the components will save you time in the long run.

Personally; for the price difference, I couldn’t justify the Pro2 over the Original Model. Many of the N2’s deficiencies have been addressed by the user community; with plenty of printable mods available on Thingiverse.

I own a N2 Plus. I decided to buy the Bondtech upgrade tonight. Also, I will receive soon the Filament Run-Out Sensor Add-on.
I will check to fabricate an air filter. Modify the extruders fans would be great too.
Like other people, I find the price on the Pro 2 Plus a bit high. By this modifications,
my N2 Plus will be more efficient. Maybe later, I will buy the Pro2 Plus.

Am I right that there is still no auto-leveling even in the Pro series?

I may be wrong but as I recall, the specs for the N2/N2+ did not list Glass Fiber Filled and Carbon Fiber Enforced as materials comfortable with them out of the box. Could these be new filaments only for the Pro series?

Is compatibility of material determined by both the temperature the printer can generate and the nozzle size?

generally filled filaments just need a more durable nozzle than brass. Stainless is a popular option. R3D has plated brass. I don't know what it's plated with, but they are supposed to hold up. I've printed CF Nylon on my N2 without issue.

I hope raise3d will sell the print heads and the new bed. I tried buying some dglass3d auto raise heads but they said they no longer mfg the 1.75 sized unit nor had any left even in just parts. I've been thinking about doing the mod someone on here did for as an overkill bed upgrade. I've tried several times and it just seems impossible to get the stock bed level.

The camera was an add-on option from the Kickstarter Campaign. They may have discontinued the option; but, as I mentioned, anyone can add a camera of their choosing, to the N2 series. The unit from the Kickstarter Campaign is WiFi enabled and powered via USB. Assuming that Raise3D hasn’t changed the printer configuration; there is a USB port (actually, just a long USB extension cable) that comes out of the same block as all other wires, attached to the cable chain. (Top-Left rear of the printer) that cable connects to a port on the main controller board.

Early on, someone designed a mount for the Kickstarter camera; which mounts on top of metal “cube” that all of the wires come out of. It is on Thingiverse. I’d paste in a link; but I’m entering this post from my iPhone and it’s a bit of a pain to search for and copy that link from my phone. Just as well, I have no idea as to whether or not that specific webcam is still available. (It has been two years since it shipped.). Regardless, I know that I have seen other, more recent designs for other web-cam’s; when searching “Raise3D camera mount” on Thingiverse. If you perform the same search; I would think that one of the available mounting bracket designs would match up to a webcam that can be purchased online. It’s this simplicity of adding a camera, on your own, that had me baffled by all of the comments from users, wanting the feature.

If, for some reason, Raise3D has stopped providing the USB power cord at the top of the printer; it is something that can still be added with minimal effort. Running a new cable through the cable pathway can be a bit of a pain; but the port on the motion controller board is still there.

Hope info this helps those who thought they were stuck, out in the cold; until Raise3D offered a new “Official” camera for the N2.

For the rougher filaments; especially the metal infused ones; Tungsten Steel Tips work best. They are extremely durable and have far better thermal transfer conductivity, than Stainless Steel. (That is why all decent Stainless Steel cookware has thick aluminum pads on the bottom, often in combination with aluminum or copper, sandwiched between the stainless)

The main downside to Tungsten Steel Nozzles, is the fact that they are EXTREMELY expensive; especially when compared to standard brass ones. Considering the cost of most of these more exotic filaments; it’s still a good investment, vs having a print fail mid-way; or just gradually decrease in precision, as your brass nozzle gets chewed up by coarse material.

The retractable heads are without question, the most appealing aspect of the Pro2 that I would like to retrofit. I have searched the web for options; but haven’t seen anything that I felt confident about being able to retrofit to the N2.

While a slight improvement over the N2’s design; I was somewhat disappointed to see that the Pro2 still relies upon the Factory Leveled” bed. If it ever goes out of level, or you need to replace the heated bed; their system is a nightmare to re-level. I’m giving serious consideration to TobyCWood’s spring mounted bed leveling mod (on Thingiverse), most likely in combination with a BLtouch auto-level mod; but I need to do a bit more research on the BLtouch and reach out to some of the users who appear to have successfully integrated that mod.

Honestly, I have the N2 and with the upgrades I have on it now, I wish it was an N2+. I have lost build height due to bed and extruder upgrades that have improved the quality of my printer significantly. I can't say the upgrades will work for everyone though. I could see that an N2 could be in theory retrofitted to an N2+ or N2++ for that matter.

We are still defining the final tech specs. For the time being, we can only inform that it will be an
improved version of the N series, with a single extruder and a price point lower than the Pro2 series.

Is there any way to upgrade from N2 series to Pro2 series?

Raise3D: Even if the base and the frame of the Pro2 are very similar to the N2, both printers are essentially different, targeting a different market, with different requirements and with a different price point. The cost of a possible upgrade from a N2 to a Pro2 printer would be extremely expensive.
Nevertheless, we are gathering all your feedback, and we are looking at the possibility of offering to N series Customers an upgrade of the extruder, end-stops and bed system, as well as the promised web-cam.
We will be working now in two parallel projects:
1. Analyse and test the upgrades from 3rd parties that are being recommended to N series printers (the most popular example is the BondTech extruder). Once approved, its installation will not void the warranty and, possibly, we will also include them in our portfolio.
2. We will check the feasibility and cost of using some components of Pro2 in N series and, if we are successful, propose an upgrade package.

Personally, I'm most interested in seeing sample prints, and in more technical detail about the extruder. I'd also be curious about the long-term availability of the current models.

As someone who recently left a corporate environment, I can see the need for a "service package" as Edward mentions in the video. But I hope Raise3D continues to support the hobby, semi-pro, and small business markets by making any year-to-year subscription type things optional. After all, the reason I didn't choose Stratasys for my prototyping lab (in a big corporation) was because I really, really couldn't budget for that kind of thing.


Raise3D Corporate Service Package will be optional to Customers who buy individuals units. For Corporate Customers who buy full systems, the final package is still being defined.

I try to look at this thing from both sides, as a user/consumer and Raise3D's side.

As a user I would expect/like to see upgrade parts available at reasonable prices as the printers do look much alike and of course are very much the same. Many improvements are sometimes logical and should already be adressed and some have been recommended by the users. (Maybe lots of things are different but at least the hardware looks very much like the N2 series).

As Raise3D I understand that it's economically interesting to build upon the N2 design and parts as much as possible but also market this new model as being more professional and targeted towards industrial users so the price goes up. So Raise3D of course sees this as a very different system even though it looks similar.

But if you compare these two angles, it's hard for them not to upset some people. If they choose not to make upgrades possible and maybe also if they do. If the parts are cheaper than the Pro2 (not counting labor to install) you can get questions again.

If they chose to completely redo design and make the build volume larger etc. the story would be different I think.

Anyway, as any N2 owner I really hope to see at least the retractable nozzle as an upgrade. I have been thinking about changing this myself somehow but haven't begun yet because it isn't simple I think.

@Vicky
Thanks for the replies and I think this comment "We are still defining the final tech specs." is meant for a next gen N2 series, but what about the tech specs of the new Pro series currently preorder status? The machines are built and being shipped. It's a bit late to be in the tech spec defining stage.

#1 what firmware is used on the new 32 bit board?
#2 will that firmware source be seen on Github?
#3 What stepper drivers are used on the new control board? (256 microsteps is not the detail we are looking for)
#4 What are the details of leveling the new 2 moving nozzles system? How does one adjust this? (Not seen in the current user guide recently posted)
#5 What details to address cable flexing concerns have been addressed? I mean if you say there are more sensors and potentially a motor or other electronics, isn't that making even more potential wires in the current cable harness that flexes and moves every time the extruder heads move in XY?
Are all cables failures detected with custom error messages? Example, if the filament detector cable fails- does that then stop the print and notify the user what cable failure is suspected?
The moving nozzle system- what additional wiring exists for it?
Pro_Wiring.jpg

#6 is the filament detector really mounted right above the extruder? How many segments complete in gcode before pause is activated?
Pro_filament detector.jpg


#7 since the photo shows new nozzles that do appear slightly different than current nozzles, with hard coated versions also be sold (AKA V2H)?
Pro_nozzles.jpg


#8 The HEPA filtration system- Is that filter widely available and 3rd party sourcing, or is this proprietary and only sourced from Raise 3D direct? Also, are most of these new features going to be 3D printed housing, ducts and brackets on the new machines as shipped starting this month?

I just have to be honest here for a second, while I know the new boards are very nice (filament detector, new control board), I get the feeling these new features feel like DIY upgrades the community or anyone could design. All of the photos show 3D printed brackets and housings. As a consumer, if I'm buying a Raise 3D because it's a heavier built printer with more aluminum in the frame than other brands entire printers, I expect that quality and attention to detail in the rest of the features. I'm just seeing a mismatch here. Example is, over time, I know that the LCD control box started off as hand built CNC'd and glued together parts, then hand sanded and painted. Later, injection molds where created as production continued and volumes and finalized designs became practical. Maybe that's the deal here, this is the $1k more expensive model than previous pricing, so while there are compromises (printed parts and other details) the user is getting the latest electronics and other designs at a discount. There is always a delta of change, production changes happen, it's just a fact.

Please, other users, see what I'm saying here. If you had a to buy your first printer and did not already have an existing Raise 3D printer (thus a $2k+ investment already), then yes, the new features sound compelling. Heck, If I had $4k just sitting, I might even buy one today. Moving dual nozzles is an often requested feature because of theory that it's the new best way to prevent some of the other problems with dual extrusion. But, like anything else, this is all new. Then there is this new focus on garnering new customers, new business markets. You are literally aiming at less technical folks who are expecting far less adjustments, technical troubleshooting, and more click and print not unlike a paper printer. I'm not fully convinced this plan is going to work. Yes, upgrading the mainboard and making the new machine less upgradeable to the user potentially limits tech support because now the user can no longer plug in a stepper driver in the socket backwards and blow the mainboard. Yes, filament detection is often discussed and a must have feature- but simply detecting out of filament and doing it at the entrance of the extruder knowing full well that's a bit late with a real limit of how much "safety room" you have before filament is actually out and air printing is possible. Again, I think the feature list is a selling point on paper. I think some of the upgrades such as the new bed surface and mounting look quite professional and are worthy upgrades. Other parts of this (moving nozzles, filament detection, upgraded stepper drivers and 32 bit processor) are far less proven (again, as implemented, I fully acknowledge new stepper drivers and processors are proven in other brands). Do I think the sum of upgrades is justified by the price increase? Yes, given a Bondtech dual feeder from the factory, given the new heated bed, given the moving nozzles system, the filament out detection. Upgrades that seem gimmicky to me is the air filtration, the optical endstops, printed housings, and some of the other details of the upgrade. To me, if your start trying to put $ figures on those items, they just aren't that big of a deal. And there lies the rub with current users. They feel like these are all things they requested for their current printer and investment, and shouldn't be forced to buying a new machine.

Also, now I'm really going to open the taps.
I was a beta tester for the camera. Let's call it alpha. But keep in mind, what I'm about to share is a point in time. I was given a camera and the beta (but seriously, it was alpha at best) matching set of Raise 3D touch Raisepack and the corresponding version of Ideamaker with camera support. It had cool features like timelapse. Don't get me wrong, you folks keep requesting it and it was definitely interesting.
But, there were some facts that might turn you off. Example was, the camera was capturing at 320x240 resolution. There was no way to move the captured images off the printer. That's why I'm calling it alpha and take what I'm saying with a grain of salt. What I tested and what is actually shipping may not be the same thing. It was nice to see them working on integration and it was nice in the control panel and so forth. Maybe the resolution was just limitations at the time. So of course I made recommendations and must have feature lists and sent that to raise 3D with literally not a word of feedback. They never sent me another beta firmware update, they never showed me the new actual camera (again, I was given a very early prototype) and never spoke to me again. So yes, call it bad blood, I'm just telling you the facts to the group you should maybe question. I also tried about a half dozen USB webcams and found one that worked- a bunch that didn't. This was due to the app being hard coded in the capture commands and that very specific resolution (32x240) which many higher megapixel cameras did not support. Even went as far as toying with configs and so forth- trying to inject the capture commands.

What resolution is the camera?
What resolution is actual video feed?
What resolution are still pictures?
Can you transfer or capture the timelaspe? (beta could only be viewed on the printer)

Again, if it were me, I'd be asking a whole lot of hard questions surrounding this feature given all that I know.
I'd want to know exactly what was implemented today in the software and firmware. I what to know what may not work today, but is planned for features.
I'd be asking for guides and examples of transferring that timelapse off the printer and or how useful it really is if only on the printer.
Maybe all this is taken care of, this is the miracle you all think it is, and you'll be just overjoyed at the camera features.

What I'm telling you is, the ship has sailed. This isn't about me getting a printer to evaluate, this isn't about money. It's about the fact the new model is shipping, it's on the boat on the way here. The time for feedback is way too late in the game. Buyers are going to feel slighted no matter what at this point. Recent buyers aren't happy and upgrade jealous (but really folks, I'm saying temper that thought). Users buying this pre-order really should be asking a lot more questions before dropping your hard earned cash. Put simply, the current product page is all the buzzwords they feel new buyers want to hear. The actual technical specs are lacking, the pictures are nice, but do have a pre-production beta test unit "this is what we could build" kind of feel. As a buyer dropping $4k-$5k before shipping and taxes I think we need a rethink here.

Again, 2 facts I absolutely, support- the Bondtech extruder and sure from a value and improvement the heated bed changes rank up there justifying the new model and pricing.

The features I question of on paper VS reality is the moving nozzles but does play into the cost increase. It sounds neat, you users keep asking for it, but is it really the miracle you think it is? What about all the other "what if"?? What's different when you have to adjust this? What's different when you have to repair or change a nozzle? What about 3rd party nozzles? What could go wrong? What does go wrong?
Again, I see phrases like this:
High repeatability. (<0.005m, 5 micron).
Light speed, <1 second switching time.
1.5mm lifting distance, compatible with flexible filaments.
Over 100,000 times reliability test passed.

But what matters is when this hits your hands and skillset.


The stuff I consider fluff is the weak filament detection integration, the air filter is just straight gimmick in my book, optical endstops I feel pretty non-impressed from a change standpoint. While the new mainboard is good- I'm not yet ready to call the stepper drivers an upgrade until more details come out. Different yes- but again, the marketing fluff is so vague, it's sad and pathetic. The current TMC2100 is already 256 microsteps in marketing speak. Yes, A4988s were use for Z and the extruders, so you could refer to an upgrade of them to TMC2100 or equiv- but is that really that substantial of an upgrade? Again, if we already have 256 microsteps for XY now- what's really being said????? The processor speed is literally just bragging rights. How that equates to any tangible printing quality or speed gain is all firmware and architecture dependent. Yes, faster is better, but to put a $ value on what that means is beyond vague and unproven. I'm not saying don't buy it, I'm saying don't make that your primary decision point. I'd love to be wrong on this point, really, that's nothing but good for you if i'm wrong, you get this great new upgrade and I get egg on my face.

Power outage second generation? I have to question how much of that is firmware update VS actual hardware change? What is really that different about it? If it's supposed to be a selling point, shouldn't that be far better explained?

Isn't it easy to just make a Pro machine with the longest axis in the x or y direction?
