Bit not touching material

is anyone else having trouble with the bit touching the material? i am currently working on a police badge. once it came to the detail on the seal the bit seems to come short on touching the material. i reset my home position a couple times and also changed my bit but still no luck. can anyone help me with this?

All you should need to do is to reset Z axis as this is the only part that change (tool stickout from collet)

What was your workflow during tool change?
