multi color fail after slicing

[bennyzul 0]

I am new with 3D printing. I am using 3d printer for making model from image data from medical imaging. Using 3D slicer fro segmentation and transfering dicom data to stl. export to cura 4.10 was smooth. setting up color for each segmentation...but when I click slice, preview showing only one color for entire merge model

where did I go wrong?

You may not have gone wrong at all.  Some more explanation of what you are trying to achieve would be good.  The first question is do you have a multi-extruder printer?

yes, my printer is geeetech A20T, with custom setting follow 1zRadio on youtube

Maybe @gr5 can help.  I'm at a disadvantage as this old laptop doesn't support OpenGL 4.1 and so I'm in compatibility mode for the graphics.

If you make a custom material it can be identical in all respects to your other material but you can set it to a different color for Cura to present.  I think it only applies to the Prepare screen though.  You might still have the colors in the preview reflect the extrusion type (OuterWall, InnerWall, Infill, Support Helpers).

Thank you for the respon. FYI yes I did set custom filament for each extruder. Gonna try to make test print today

As I recall, that is a 2 in 1 out extruder.  Within the "Printer Settings" (a plugin that is loaded from the MarketPlace) are the settings for "Extruders Share Heater" and "Extruders Share Nozzle".  I believe they have to be checked or the hot end will use the standby temperature when you switch tools.  Another problem can be the retraction and prime distances for tool switches.  I think those settings are in Dual Extrusion section.

A20T is 3 in 1 extruder

I will look the setting as you told

right now printing activity is grounded because something went wrong with my hotend. it does not heating filament anymore. I think the thermistor is defective

order new one and try to hack a new thermistor for the old hotend
