- Bambulab A1 - Stock Ludicrous mode vs custom profile speed test
You won't believe the difference
Stock profile has ludicrous mode enabled and this is pretty much how most users will use their A1 printers- however if you are willing to play around with the profiles you might just be surprised by how good this thing is
File available here if you want to give it a try

Rocket2.stl is the version in the video
0.4mm nozzle
Generic pla
0.2mm layer heights
Before changing anything slice a model so you can get an idea of print time prior to making any changes - you will slice the same model at the end and compare times
Settings I changed below
In the slicer select your printer and nozzle setup (in my case A1 with 0.4mm nozzle)
once its selected you can click on the edit button at the end of it in the slicer to modify the settings
The edit page shows 4 tabs across the top
Basic information
Machine G-Code
Motion Ability
Extruder
We will only be concerned with Motion ability and extruder
Select motion ability and scroll down to jerk limitation
change
Max Jerk X to 6
Max Jerk Y to 20
Max Jerk Z to 20
Max Jerk E to 6
Now select Extruder tab
Z hop when retracting change to 0
Z hop upper boundary change to 0
Z hop type change to slope (may or may not make a difference)
Retraction speed change from 30 to 40
Detraction speed change from 30 to 40
Z hop upper boundary change to 0
Save that - I named it speed setting in slicer for handiness
Now back to Bambu slicer main screen and select your filament
I chose Generic PLA @BBL A1
at the end of the filament there's an edit button ( its between filaments 1 and 2 if using multiple filaments or ams)
In here we have 4 tabs
Filament
Cooling
Setting Overrides
Advanced
We will be adjusting
Filament and Cooling
Select Filament
Change Flow ratio from .98 to 1.1 or 1.2 (you may want to adjust this after you do your initial print)
Scroll to bottom of page and click on Max volumetric speed and change this from 12 to between 48 and 52 - (I used 50 but you want to play around with this depending on results)
In here you may want to add some extra temperature for the nozzle due to the increased speeds currently 220 on first layer and 220 on other layers (I suggest bumping this to 225 on both)
Now move to the cooling tab
Under Part cooling fan - change Fan speed to 100%
Untick - Slow printing down for better layer cooling
Cooling overhang threshold - change from 50% to 0%
That should be it close out of this or save it if you plan to use it again
With your modified printer chosen and modified filament selected slice the model you previously sliced and fingers crossed you should see a considerable time saving
If you are unhappy with the changes you can revert to standard by hitting the little orange undo button in front of any items you changed - Jak na to + styl
Settings now added to the video description - let me know if you have any issues and I will help if possible - please bear in mind this is increasing speed so will likely have an effect on print quality if pushed too far
Remember that ludicrous benchy that you made a video about? That video made me get an A1 and it just arrived and went through it's first pre-sliced benchy as well in 20m. And it has a better quality than all my other printers... :D
Thanks for the videos, looking forward to more content.
That is awesome!
And here's me coming from an Ender3 thinking the stock was fast. Looking forward to you putting the settings up this is huge!
will add them soon
also i had ender 5s and ender 3 s1 pros and the bambu stuff is just unreal
I followed the instructions and sliced again with the new settings but the print time shows it is literally unchanged?
Excellent instructions in the description. I'm going to try this out on my a1 👍
best of luck
Just tried these settings, cut my print time in half and quality is great
thats great glad it worked
Gonna try this tomorrow
let me know how it goes
So the one that finishes faster isnt even in Ludicrous mode? Just standard with these settings applied?
sorry i missed thos comment - its also in ludicrous mode but with a custom profile for the filament and as you can see in the video it releases a lot more speed
Where does it get its speed from ? Is it because of the linear bearings, the servo the drives the axis, the firmware, all of those ?
il be honest i dont know but for a bed slinger its mighty impressive
More amps to the motors.
sorry, i printed PLA in ludicrous mode and it fails my 2nd layer everytime, d u know why?
what model are you printing ?
i rarely print in ludicrous mode i dont really see the need but its useful to have the ability
Good morning, thank you very much for sharing, I find the time difference incredible, do you use this profile to print anything? What supports do you usually use for organic pieces?
generally i just leave it on stock settings but if i need something printed in a hurry i revert to this one
i use tree supports generally and on print bed only
Thank you very much for replying, I got the A1 today, and I saw that there were people who were rubbing the nozzle against the printed parts, did you notice that it will happen to you? If you can give me some advice on how to set up the normal profile, I'd appreciate it ;).
@konradduncan817 normal profile is just your machines stock settings for any given roll of filament selected in your slicer
How is it compared to P1S? Been on the fence of A1 or P1S. Was going to get X1C but would rather save the money until Bambu releases a larger printer.
i have 3 p1s models and they are faster or at least closer to my faster setting here
i can print nylon without issue on the p1s but strugging with cooling on the a1 so if you plan on printing plastics other than pla and petg tpu etc then go for the p1s (budget dependant) but the a1 is a serious machine for the money and the ams lite is pretty good too just takes up more space than the p1s and ams
@@Kenprints thanks for the info! I'm sure as soon as I order the P1S that will announce the new printer 🤣
@Poezessed_ haha thats my fear also but look i did that with the a1 mini i ordered it and the a1 was announced before they delivered the a1 mini so i sold the mini in its sealed box and just went for the a1 instead
@@Kenprints more space than the p1s even with the top mounted ams?
yes even with top mounted ams
when you allow for the motor and poop flinger plus the forward and back motion of the bed the A1 takes up approximately 50cm x 60cm that incl a small collection bucket for poop and the p1s takes up approx 50cm x 50cm incl space to reach a poop container at the rear from the side of the printer
Thanks for sharing, but the speed on the left doesn't look like Ludicrous mode at all? If I am not wrong, the speed was limited by the minimum layer time (normally 5-6sec). The one on the right obviously has a very short minimum layer time (around 1sec).
the one on left is definitley ludicrous mode but its ludicrous mode of the stock pla settings that bambu studio used for slicing that rocket nothing was changed just left alone the way an average user would use it if they were to slice the rocket
the right hand side as you say has been modified to allow it to run up to a faster speed in ludicrous mode but both are running at 166% but at different settings within the slicer
hope that makes sense -
@@Kenprints Thanks for your thorough reply. I believe the stock Ludicrous mode in your video was definitely limited by minimum layer time and can be easily speeded up by lowering the minimum layer time within the Cooling tab of the filament profile.
i believe that was one of the settings i changed alright
will list all in the description in the next few hours
can you do a video like this but with the p1p/p1s?
adjust the same values and compare ?
ive made the changes in the slicer only at present for the p1s and in stock form without choosing ludicrous etc it has a time of 48 mins for the rocket in vase mode
with the same items changed as i changed for the a1 it brings the time down to 13m and 31 seconds again thats without choosing ludicrous so now you have me wanting to give this a try as a comparison 😂
just ran it on one of the p1s and same modified settings as used on the a1 and pretty much identical speed (if anything the a1 is slightly quicker by a few seconds) il try get a video up shortly
video now live
I dont have a bambu so i might be completely wrong but that doesnt look like ludicrous mode at all, and u also didnt mention minimum layer time in the slicer settings, u should change that as well otherwise u not reaching high speeds
Love the printer but my the sound is keeping me from pulling the trigger as i dont have a seperate workspace
mine is in my office beside me along with the 3 p1s machines and most days they are printing and dont cause any issues or distractions - bear in mind i dont print in ludicrous mode which means they normally print much quieter
@@Kenprints ah that's good to know. So the jet engine is only active for Ludacris mode. My ender is currently in the living room beside my TV
@mikeymclachlan9506 yes if this was printing in standard mode you wouldnt really pass any heed to it
i see now the config list , but its more easy if u upload some stl with the configs..
put for example a cube
Very cool. Though I don't understand why you have glue stick on textured PEI. I've run 1000+ prints on my P1S and have never once used glue stick on textured PEI. The only adhesion failure I've had was the models fault when I was testing maker world and sending prints that other people sliced directly to the printer.
i had glue on the bed already from a previous print but also didnt want the rocket coming loose at higher speeds - generally dont have adhesion issues at all but sometimes use the glue as a precaution on longer or taller prints
@@Kenprints Fair enough.
Whats your profile ?
il put up details shortly if anyone wants to give it a try
@@Kenprintscould you upload? Would love to give it a go. Thanks
@@Kenprints its only for vases etc right?
@5doolar no the speed change applies across the board i have only shown it here in this vase type item as it was quick and simple to show without wasting time or filament
ha ok thanks i will try it
@@Kenprints
Since there were no travel moves, travel speed (non print movement) was not a factor.
Your PrintHead is modified! Not stock! Hard to compare to normal A1 😞
u mean nozzle ?
