probably a typo
I know that â I can read, and I already mentioned in my last post that the code is different.
Apart from the VentoBox option on the P2S and the second auxiliary fan (P10) on the X2D, the code is âalmostâ identical.
If you want to mimic the PETG printing behavior of the P2S (and it works well), you would have to deactivate the left auxiliary fan.
That means deleting/commenting out all M106 P10 entries in the machine start gcode and layer_change gcode, and in the PETG filament profile â under cooling â setting the 40% for the auxiliary fan (itâs 0% on the P2S!!!) to zero percent.
I suspect that the latter will already improve PETG printing.
It would be necessary to investigate further to what extent the exhaust chamber autocooling (M142) affects the deactivated left AUX fan.
I also noticed the very short set airduct mode in the machine start gcode for the X2D.
X2D start gcode / set airduct mode:

The min_vitrification_temperature <= 50 comparison is not available for the X2D. Iâm not entirely sure if this is only for the VentoBox option on the P2S.
However, the M142 values ââdiffer between the two printers:
U0.3 V0.8 (P2S) vs. U0.6 V0.8 (X2D)
The X2D regulates more strongly/higher during autocooling.
Perhaps this offers a solution to the problem?

Thank you for this profile. It is getting me by at the moment, but we still need Bambu to give us other options besides strong automatic cooling.

I think I understand why they did what they did. Even judging by the comments in this thread, many people seem to think there is one universal setting that will work for all models, regardless of the shape or size of the part, just because it worked for them on a single model on the P2S.
In my opinion, Bambu is trying to make the process as painless as possible, while still leaving manual options available for users who want more control. Figuring out the ârightâ fan settings for your specific needs is much harder than simply slicing with an already prepared profile. So if someone already feels thatâs too much of a hassle, they probably shouldnât be adjusting those settings in the first place.
Bambu could block what we are doing here in a second, but they clearly understand that advanced users have different needs, and they do accommodate that. Personally, I donât even think they need a dedicated âmanualâ option in the menu. If they ever added that, I think it would be a mistake and would only create more support tickets than necessary.
People complain that Bambu doesnât allow tinkering, but when they do, people complain that theyâre not making it easy enough

In this case they arenât though, are they? Why not add a menu option to control fan speed? Seems like something obvious to have. As for support tickets, BL can just say âwell, you have manual fan speed set, change it to auto then get back to us if you still have issuesâ.
In your original post it seems you can already adjust the fan speed via the menu but it resets back to default. Is that right? That almost sounds like a bug, rather than an intended feature.
Hey, but what do I know, I still donât own one LOL.

Just my opinion: I think the majority of users are beginners, and they would start the print job, lower the fan to 30%, forget about the 10-hour print, leave, and then 8 hours later â if there isnât a massive fire â a clog or blob of death would appear. Then everyone would start screaming: âWhy doesnât this printer know it needs to readjust the fan speed?â
So they made an auto profile that works for 95% of prints.
We are making a manual profile for long PETG parts where warping might â but not necessarily will â appear. I still stand by my theory: Bambu Lab protects users from their inexperience, and rightly so.
I donât believe a beginner will be looking at a 10-hour print and monitoring temperatures just to manually readjust fan speeds later⌠ainât happening.
I believe they should add the menu option to disable auto cooling entirely, but bury it in the slicers advance and develop modes so that itâs only accessible to the advanced users. Well, itâll technically be available to anyone who enables develop and advanced modes, but a newbie isnât going to find these settings until they need them.
Did we ever figure out why your gcode is different and has the extra lines in it compared to the default?
Just wanted to update. I spoke with support about this and they are actively seeking solutions to allow users to control the aux fans. I suggested a toggle to disable auto cooling in the slicer but to hide it in develop mode like some of the other advanced user settings are. They seemed to like this idea. Their main worry is print reliability for people who donât know what theyâre doing. They donât want rookies turning them on manual mode and then it causing issues such as heat creep because the chamber wonât be cooling. This worry seems justified to me. Hopefully they give us advanced users a toggle soon. Iâm willing to bet all of us advanced users already have develop mode in the slicer turned on.

I just spent almost the whole day debugging why my PETG prints were lifting up. Fresh X2D owner, and spoiled by P2S. The last thing I expected was the aux fan, as I had prepared the profiles accordingly. Itâs loud in my workshop, so I didnât notice it turning on. What a surprise it turned out to beâI was tweaking everything, and aux fan speed too.
The issue is complicated. In my experience, this option needs to be a bit smarter than a simple on/off, as everything depends on the geometry of the print. I managed to complete mine by lifting the top glass, and manually turning off the fan for PETG and turning it on for PLA before the g-code actually changed the settings. If I left the fan off, the aux extruder struggled to feed the filament as it wasnât adhering to the PETG surface.
Granted, Iâm not using Bambu filaments, so perhaps itâs a completely different ballpark, but stillâfor a printer designed with an Bowden as aux so basically a support mainly, itâs a bit of a bummer how it handles it. At least, thatâs how I feel right now after wasting a lot of time and filament.
Still, the print finally came out great. Iâm just hoping this will be sorted out in the slicer interface, as Iâm not looking forward to editing the g-code for every future print.
I had the same issue when printing supports. The fans kept spinning up for PLA making the PETG very brittle.
Tried changing gcode, but nothing really worked.
Then i realized: why are the aux fans not spinning up for PETG, but do spin up for PLA?
I believe itâs the âSoftening temperatureâ setting in Filament settings (first tab)
When set ridiculously high, say 100 degrees, the aux fans do not spin up.
(Which in its turn caused a nasty heatcreep blob on my X2D)

Hi.
This is an absolute pain in the â â â when printing PETG with PLA support interfaces on the X2D.
The printer automatically ramps the auxiliary cooling fan to 100%, and within minutes the PETG starts warping, lifting from the build plate, and ruining the print.
What exactly were QA and QC looking at when validating these profiles and default cooling behaviors? One of the main selling points of the X2D is dual-material printing (with PLA/PETG in my case), yet the machine actively sabotages that workflow out of the box.
For a machine marketed as a next-generation dual-nozzle platform, this is honestly a pretty bad look. Users should not have to spend hours hunting down hidden cooling overrides just to make a flagship feature work reliably.
What a shame. 
The hardware deserves better software defaults.
@Sebo3D1 thx!
Also if i have such behavior where Aux fan must rump to 70% - it doesân work, itâs will work at 40% and donât ramp up?
The code I posted allows for full manual fan control, exactly as originally requested by the user. There are no automatic âramp-upâ features or other advanced control logicâjust straightforward manual control with safe initial settings.
The code can easily be modified for specific filament type or use cases. For example, you could increase or decrease the left or right fan after a certain layer, adjust fan speeds based on print stages, or implement virtually any custom behavior. With custom code, almost anything is possible.
The challenge is that there is no single âbestâ fan control strategy that works for every scenario. Different materials, models, layer times, ambient conditions, and print geometries all require different approaches, making a universal solution impossible to implement.
In theory, some kind of AI-driven thermodynamic model could automatically adjust fan speeds based on part geometry, material properties, and real-time printing conditions (temp). However, Iâm not sure many people would be willing to pay for that level of complexity just to print slinky dragons.
Therefore, in my opinion, it is better to control the fan from the filament settings, so for a certain geometry, etc., it is faster and easier to fix there than to correct the g-code of the printer, especially if you do not know where and how.
Can you tell what i need to uncomment for Liner ramp up settings start work?
The do it from filament settingsâŚin my opinion thats not the way, but feel free to try it and report back
Hi,
i played a lot with the automated fan control and this is what i came up with:
M142 P6 controls the exhaus fan
M142 P1 controls both aux fans
R: lower regulation temperature
S: Upper regulation temperature
U: minumum fan speed for regulation
V: maximum fan speed for regulation
O: Threshold for temperature alarm (Only working for M142 P1)
with those controls in mind its easy to generate a own post processing. I fully switch off fans during the first X layers defined in the filament settings. For low fan speed of M142 P1 i use the aux fan setting of the filament setup, and for max fan speed i add 20% to this value. The alarm value is choosen by the lowest softening temperature in the project, just to be on the safe side when printing PLA. I hope that information is helpful for some of you.

Hi,
Is it possible to add M142 P1 fan control to filament settings?
itâs make me crazy - print only PETG, L&R AUX fan go up to 100%, and after 20-30min model warping from the badâŚ
X2D PETG.3mf (28.6 KB)
With this setup, the left fan (L) is set to 50%, the right fan (R) to 60%, and the rear exhaust fan to 80%. Once the print starts, you can manually adjust these values, and they will remain at whatever settings you choose.
It is possible to control fan speeds through filament profiles, but in my case thatâs not ideal. As temperatures change throughout a print depending on the model, the automatic settings can still end up pushing the fans harder than necessary.
In my opinion (and Iâm not an expert), creating reliable automatic fan control based on chamber or environmental temperatures takes a lot of time and effort. Bambu has come close, but for example, when using PLA as an interface material, the fan settings can still be too aggressive. There also isnât a universal setting that works well for every model and print size.
For the types of models I print, manual fan adjustments have given me the best results.

Does the automatic âstrong coolingâ not override your fan setting on every layer change? I tried capping the aux fan speed in the filament settings, but it just automatically jumps to 80%. Is there not any fix besides editing the G-Code manually?
i added that in my example.. you can set M142 P1 by using the parameter additional_cooling_fan_speed
in my example i use the settings of the filament parameter for lower threshold and then add +20% for the higher threshold value. This will result in the fan using the settings of the filament most of the time, but if the temperature reaches the limit value it allows to ramp up the speed to a maximum of additional_cooling_fan_speed + 20%
This setting will also take the filament settings for first layers into account. If no colling is set for the first x layers the aux fans will be disabled.
For dual nozzle prints it will switch the settings dependent on the active nozzle and choosen filament. For me it works well, I print petg and use Pla for support layer. No more warping..
The exhaust fan is controlled in the start code dependend on the material with the lowest vitrification temperature used in the project..
