Multicolor logos on MMU2S with Prusaslicer 2.0: not able to position objects in Z direction
Hello,
I am trying to create a PRUSA logo like the test one, with all the letters of different colours, to be printed in automatic MMU mode (not manual filament change mode) .
I have all the separate letters in STL and the base.stl.
- I start to add the base on Prusaslicer and assign the extruder 1
- I add the first letter, and assign extruder 2. Prusaslicer align it with the bed. I move it to the exact position on left.
- Since I don't want the letter aligned on the bed (because I want the base completely printed in fast and unique black fill, without any not useful mid-color change on the inside infill corresponding to the colour letters !! 🤐 ) I need is to put the letter just aligned over the to top layer of the base. I want to do this by moving the letters in Z direction of 3 mm up.
- When I select the P letter and click on move, I can raise it just over the base, but as soon as I release the mouse, it drops again on the base.
It seems like I can't move the object in Z direction. - Even typing the exact height on the table on right of the screen at Z height, does not help, as soon as I press ENTER it reverts back to the original height from the base.
- Why I can't raise the object ?
- How I can manually move an added object over another ?
Regards

i always do it a little differently, i separate the objects in Fusion360 and export it as a single STL.
then in Prusasilcer i right klick the object and select separate to parts, that way i can set the extruders as i like but it maintains the position as it was imported.

If your STLs are ready for multi-material (have there position offset embedded in the file), then you have to import them as a single object with multiple parts. You can do this all at once:
Or you import your base object and do a right click on it to choose "Add part > Load...".

Many thanks. I followed your process and it worked. 😊
So, it seems that in order to create a multicolour object printable with PrusaSlicer, we need:
- Design it in CAD already fully assembled, with the all the colour parts positioned in their final position.
- Export each colour section separately from the CAD
- Import all together with a multi file selection in PrusaSlicer and confirm that are parts of the same object
- ..or import the first part, and the proceed with ADD PART.... with all the other.
- PrusaSlicer "automagically" moves them in the correct position.
- Assign the extruder to the parts (it's a pity that Prusaslicer does not display the parts with the filament colour, but it uses the extruder colour code.)
- Slice it.
- Print.
Indeed is a new way to create colour objects, but it is not complex. I never created colour objects before having a MMU.
I currently use ThinkerCAD to design objects. It supports also colour, so it is easy for me have a look of how it will appear.
I still trying to learn Fusion 360.
I started to test the MMU2s, and I want to invest some more time how really works, as example to test the transition colour table.
I do expect that the material of white filaments are different, so it may be required to purge much more material, as example, moving from a "black" filament to a "White" filament in order to obtain a perfect white.
I should learn well how to tune it.

Yes, the preview uses the tool/extruder color. But you can adjust the color under "Printer Settings > Extruder X > Preview > Extruder Color". I like to change this to the filament color, so the preview is accurate. If you save this project you will have these color settings for future reference and adjustments.

A good starting point for this purge settings is the table on page 24 of the handbook.
