What is the *real* maximum print volume?

I am looking for guidance on the real maximum print volume possible with the X1CC. The printer bed says 256mm x 256mm x 256mm, but if I create a box primitive this large on Bambu Studio it raises an error saying that object is out of the plate boundaries.

If I reduce the volume to 200x226x250 it fits within the plate and doesn’t interfere with the flow calibration lines, but very close to it and I don’t know if it is safe to print.

I would like to print a vase/planter as large as I can. Thank you!

Hi JPolisel,

If you turn the flow calibration off and manually do your own flow calibrate you can get more.

Then to get even more you have to add the Bambu Lab X1 mod part.

I would check out Orca slicer if you are not already using it for the flow testing and more slicer settings.

Hope this helps you out :v:

Thank you so much @3DTech ! I am not using the Orca, I am actually very new to 3D Printing and learning, I will check it out.

This is what I was able to get but you have to move the part around :grinning:

Another thing you can do is pause the print and then remove the calibration and purge lines then resume the print again.

JESUS CHRIST THIS TOOK TOO LONG TO FIND all these idiots on reddit mentioning the exclusion zone but no one can list the real build volume, frick those commentors and whoever wrote that useless wiki on the mod that no real consumer has time for

Got my X1 carbon with AMU about a month ago and just now discovered that it has an exclusion zone which limits the actual work area of the print. Seems a bit misleading on Bambu’s part.

Welcome to the forum.

Yup, it’s a conspiracy. Bambu is stealing your build plate! Oh no Oh no what are we going to do? Wait…

They clearly mark it in Bambu Studio…

And they give you a warning if you place anything in that area…

Oh and they have a wiki page that explains the issue and how to disable the area so the entire build plate can be used…

Nope! It’s clearly a conspiracy!

Chiming in years later because this thread is still useful - I wanted to clarify for anyone though that the restrictions - though we can disable them (disabling front left restriction area disables AMS use - and disabling Z-Hop height could result in failed prints once the height over 249mm is reached) - there is still the ability to choose your max depth or width to 256 without restrictions - of the two,

You get the most space with a rectangular model/arrangement using 256mm depth (front to back), and 238mm width.

While if you set your model wide, (left to right) to 256mm, you are limited to 228mm in depth.

I keep this little note to remind me:

Build Volume with Z Hop

Full Depth (more space front to back)
H 249mm
W 238mm
D 256mm

Full Width (more space left to right)
H 249mm
W 256mm
D 228mm

If you rotated that cube 90 degrees though, you’d be able to max it out at 256 x 238 x 250 because the restriction area is 18x28 so you’re more restricted when positioning in one orientation vs the other.

It may not be a conspiracy but it is ■■■■. The documentation on this sucks because they want us to think that we can print 256x256. In fact you can’t and all the trial and error I’ve been through today to make this work is a waste of time. Bambu wants to foster the image of easy to use. Well this is not fitting that image at all.

I just designed a massive project thinking that all Bambu printers can print 256 in height, only now to discover that this is actually not the case? Is there a way to unlock the print height of 256 on the P1S and the X1C or is the listed specification of 256mm just a lie? I would really like to include those models because otherwise only the A1 will be able to print the complete project. Thanks!

For reference, this is the model:

And only the screw is just too long at 253mm

Can you print the screw on a diagonal?

Wait until @Rossero notices BL sells the A1 mini.

Not sure about that. But @MZip suggestion sounds pretty pragmatic. As for the upload of print profiles to also cover the large number of A1 Mini’s as @MalcTheOracle pointed out, there is this marble run entry where the central screw was split specifically for the A1 Mini profile. May work much easier than trying to overcome machine/slicer limitations.

Yeah I have already split the screw in half for the P1 and X1 right now.

I was just wondering what I was missing, turns out there is a little star…

Trying to print a prototype I’ve just made,
44 x 74 x 256mm

However BS slicer says it is too high…
So I simply used the change size, unticked the “Uniform Scale” box
one mm at a time until I hit 250mm upon which it did not shout out that it was outside the build space proximeter…

So did you guys find the real build size limits (including the clearly drawn white “exclusion area” box in the corner of the build space)

Is 250 the max height?
(I am making a competition holder and 256 would make it completely flush, and 250 would make stuff protrude in a not hrmmm aesthethic fashion :confused: )

Replying to my own comment since… some of y’all need to read it :eyes: :grin:

Did you make all the required changes for height in Bambu Studio?
