What do you really get for a $350 desk top engraver ?

between Inkscape and blender i am making myself crazy i am looking to explore the more creative side of things i can do on this machine but figuring out how to do a Z axis height map from a 2d image is out of the normal box for me and proving to be a bit of a challenge for me  

seems pretty easy to work with compared to what i have been trying to work with

i had no idea what kind of stuff you could do with a simple image in Blender until a few days ago. but i had this Stl. file in about 5 to 10 minutes in Blender.

   

now that i have played with software i don't know very much about i went back to things i do know about and landed back in the solids  i can see some attractions to mesh modeling and sculpting but it lacks what i feel is control over position. So i have a hard time letting go of fusion 360
i have been messing around looking to push the limits of fine details and have a plan to test things. tiny features require tiny tools so i picked up these to see how things work? here is the test subject as well
 

i'm like a squirl with my information acorns and i don't discard anything so no worries  and i did try it the biggest hang up i had was no way to look at the tool path other than to post and load it in the machine controller but other than that small issue over all it was quick and easy and it might work at some point for me later on when i come across a use for it  

i remember that movie and the part you are referring to lets hope my acorns are not that problematic and i find a use for them before i end up frozen in a block of ice

this is a tool path simulation screen shot with fusion 360. just to give some perspective of how small these features are the depth of this undercut section is only .03 deep and the design in the undercut section is only ,015 in height and the radius on these features is only around .008. i see some small sections that are to small to get into but for the sizes i am working with i would say it's getting pretty darn close to 100%
