Hello!
The way the software on the Pocket NC V2 works, the machine has to move in total number of degrees when moving the rotary axes. This means that, in order to cut in the direction you want, the machine needs to start that operation by positioning the B axis in a way that will allow it to make those rotary moves while staying within a certain range. I believe you can get rid of the initial "wind-up" by changing your cut direction in Fusion 360.
I hope this helps! If it doesn't, feel free to reach out to us at
ser...@pocketnc.com with your Fusion 360 file and we can take a closer look to see if we can help further.
