In Step 2, we had you download ALL custom SeeMeCNC slicing profiles to your computer. (master.zip)

Locate and extract the downloaded files on your computer. These are the "slicing profiles master" zipped files.

In Cura, select "Preferences" in the top menu bar, then "Configure Cura..."

A window opens, and on the left, select "Profiles". Below default profiles are custom profiles. (note: default profiles will not work)

Select "Import" then navigate to the extracted slicing profiles folder. slicing-profiles-master > SE300 > Cura > any 4.6 or higher (see photo one)

Open a slicing profile. The slicing profiles have an extension type of ".curaprofile" and are catagorized by hotend type and nozzle size.

The new slicing profiles will now show up in the Print Setting list in Cura under the Profile drop list. (see second photo)
