How do I load a vinyl cutting cartridge into CNC Stylus?

Fitting and removing a collet

You will need to select the 16-15mm collet size to hold the cartridge. Collet sizes can be found on the side of the collet for the larger collets.

The nut features an eccentric washer which requires force to be applied to a specific side to allow engagement and removal of the collet with the nut.

After selecting your collet, you will need to push it into the nut until it engages. 

You will hear an audible click. You can check this by inverting the assembly. If the collet is fitted correctly, the collet will not fall out.

To remove the collet, push the collet to the side using your thumb. You may need to rotate the direction of force against the nut.

Loading the vinyl cutting cartridge

Once you have selected the correct size collet and have fitted  the collet to the collet nut. You can now insert the vinyl cutting cartridge into the stylus. In the diagram below, you can see the part of the assembly we need to clamp onto to effectively hold the cartridge.

The cartridge should extend roughly 15mm from the CNC Stylus. Ensure the cartridge is parallel to the axis.
