Cutting Part, one part moves!  

RE: Cutting Part, one part moves!

If you want to change the extruder (MMU2 filament change) on the Z axis (height) you should use the change extruder function in the layer preview.

1. Press CMD/ctrl+6 to switch to layer view.
2. move to the layer where you want the change with the vertical layer slider, to the right of the 3D view.
3. When you fint the spot, press the + sigh and select "change extruder" and the extruder/filament you want to change to

If you want a quick color change on x, y or z you can use modifiers.
right click your part and chose "add modifier" and choose box or sphere
adjust its position and size and simply select another extruder for the modifier in the object list on the right.
This will modify the extruder used for the overlap of the original part
Press CMD/ctrl+6 to switch to layer view, and see the effect

Thanks, I will try that. I was thinking splitting the part would accomplish the same thing as importing a multipart .stl, where the parts stay in the position originally created.  Still wondering why splitting a part does not keep them in position though.

RE: Cutting Part, one part moves!

Yes it was confusing at first, but its how slic3r works.
In PS there are two types of things on the build plate:
Objects and parts.
Objects with a single part is what you normally get when you drag and drop a .stl into the plater. All objects need to touch the buildplate.
An object can also have multiple parts, these can be printed geometry or modifiers. Only one part of an object need to touch the buildplate.
If you are set up with a multi extruder importing multiple .stl files in one go will prompt you if you want to create one object with multiple parts or multiple objects each with one part.

Using the cut command you create two objects with a single part each, and so they both need to touch the buildplate. The wording of the cut dialog is a bit confusing because it mentions "bottom part" and "upper part", but this is referring to the cut line.
It would make sense, when you select to keep both "parts" that it would ask you: do you want to split into objects or parts, but that would be a new feature...

BTW. you can also right click an object in the plater and select "height range modifier" to get local control of the extruder used per object, not the global control of the layer hight in the preview. using this feature you can create multiple extruder changes at different layer heights for each object on the plate.

RE: Cutting Part, one part moves!

I have never tried modifiers, will have to play with those.  I have printed quite a few multi part files, just assumed that splitting a part would create a multipart without moving one of them.
