3D carving troubles

I have tried to carve several different small 3D projects that I thought would be fairly easy to carve as this was my first time trying to do this. I watched the videos and learned how to adjust the project around the material and bits I would be using. Seemed pretty simple when I was setting up my project while I was watching the video from Inventables. All goes well during the roughing cut. I change bits, set up for the detail cut and nothing happens. I tried 3 different projects that were posted on the Easel CNC Software Users Group on Facebook and posted the issues I’m having but so far, no one has been able to help figure out why this is happening. Thank you in advance for any help.
