Oscillating speed of the tool


I am an absolute beginner with CNC and the Nomad 883.

I managed to create the wrench, but when I tried to make the face from the Renshape a problem occured:

The tool has oscillating speed. First it revs up to what I am assuming is max RPM, and then it just cuts power and completely stops while still moving the drill bit in x,y and z directions. This causes crashes, how can I deal with this problem? Is this as intended?

Thanks for your help,
