Carvey doesn't home correctly at start of cut

Just got my carvey and trying to make my first cut. My unit does not hit the “homing” or whatever switch it’s called to test the depth of the bit. How do I change this in Easel??

I can just tell you that the way the tell you to do it is partly wrong!! i need to change it too so it works now.

I got this problem today. the drillbit hits the clamp instead of the switch.did you guys get it fixed??
