At least Google if you're guessing when advising other users!
I own and use exactly the model which the OP requested information on and I'm not answering based on a guess or a Google search, I have actual physical experience using a Gravograph IM3 for diamond drag and rotary cut engraving!

I answered question "like a pantographt" not about an IM3 I told him to google IM3 or search youtube.

;-)
I have spoken to friends regarding tools used and why they do not use CNC engravers as they have a CNC fibre laser, their response was about the time and setup. The way to quality engraving is craftsmen with years of experience and professional equipment that will never be replaced by any hobbyists with V-Carve type tool paths.
