I have designed a chess set (link) that prints easily with AMS, but should also be printable without AMS. Yesterday I did a test print on one of my other printers with three prints/passes:
This is after the second pass/print. As you can see, this worked fine, but you need to push the model off center for the probing of the bed. The annoying thing however is that every plate in Bambu Studio has completely different coordinates which makes aligning them correctly a right pain in the something!
Ideally I would like to upload a print profile where the user can just print one after the other, only removing the purge-droop in-between prints. The print file would look something like this:
But because every plate has different coordinates (you can see the origin top left), aligning them across plates correctly is almost impossible. For instance the coordinates of the black pieces:
X plus 437
Y minus 180
Z floating around somewhere?
But my question of course is first: please fix this
But secondly, does anyone have a workaround, a setting that I am missing or an official distance between the plates from the origin so I can do the math myself?
Because I would really like to make this an option for my current models but also future ones if I do ever the same kind of trickery again.
From reading what you are trying to do, I donât think there is a bug here. If you are trying to align different objects on different plates directly in the slicer that is a very fiddly and error prone thing. Personally I would do it by editing the 3mf files directly. As a workaround instead, create 4 small markers at the corners of an almost plate sized square and position your offset model inside the markers. This object will have the same bounding box no matter what is inside and the slicer will likely position it in the same place each time you load it on separate plates.
There is no bug or something broken, just a very stupid integration of how coordinates work in Bambu Studio. You can still fix things by making them less stupid, even if there isnât a bug.
But to show you what I mean, here are three models centered on three plates:
As you can see, every âcenterâ has other coordinates and are therefore unusable. I guess these are âworld coordinatesâ. But if I ask somebody to move the couch about 1m from the window I also donât use the equator as a reference point.
Right now I centered these three models with âauto arrangeâ, creating these partly different coordinates. But with more complex models like the complete project it gets increasingly harder. Especially since I wanted the models off-center.
So what I want is quite simply plate coordinates and not coordinates from some almost random point. And if that doesnât work a nice workaround
I have placed markers at the board to keep all centers aligned, but as soon as you rearrange things you lose all reference points and there is no way to be sure everything is centered if you use the coordinates.
And thatâs why the distance between the plates would be nice, because it doesnât only position relative to the origin at plate one, having all coordinates one plate over, but it also has distance in between plates that are also added to the coordinates.
I understand now, thank you for the excellent illustration! I agree that âworld coordinatesâ are a poor coordinate system for the âmoveâ operator, what you want is for them to be in plate relative coordinates.
This doesnât look like a difficult code change, I might try making it myself just to document it better.
but this can easily change, maybe even between A1 and P1, who knows. For now I am going to create a print profile based on these coordinates and hope for the best I have to watch out though, because adding plates can cause previous plates to jump to other coordinates
Sorry for opening this topic and resolving it myself, but itâs just a weird way of using coordinates and I also needed to vent. And who knows, maybe something will be done about it! Not sure when world coordinates are more useful than plate coordinates.
Have you downloaded the latest Bambu Studio which came out yesterday?
I didnât see it mentioned in the thread here, I could have missed it though.
It has two coordinate system, you have world and the new object.
If you swap to object and the selected object is in the select plate, it works from the centre of the build plate .
If you have a part that is centred, the object coordinates show zero for everything.p, no matter which plate you have selected.
This should make it easy to achieve your goal without spreadsheets in the mix hopefully.
If you select a model with object coordinates that is not one the selected plate, your values are based on the distance from the centre of the selected plate.
No I didnât, was slowly getting closer and installing the update made me worried I could start all over again (if they increased distance between plates by a mm or something). I have saved the final 3mf file now, based on the spreadsheet. I will update Studio and see how it opens my 3mf and if it stays correct and resolves it for future experimentation Iâm a happy man! Thanks!
This object coordinates are 0-0-0 while it is off center, whichever plate I choose. But the 3mf wasnât bricked during the update so Iâll just print and upload it and hope for the best haha.
