It looks like my Z axis can go down a little more. Should it be able to?
I tried increasing the Z Max travel parameter from my default $132=94 to $132=96 but it did not seem to increase the travel.
Adjust the Travel Dimensions in Carbide Motion | Settings if your steps/mm for Z in Grbl for $102 are correct (should be 200 for a Z-Plus).

Carbide Motion also has a size limit. If you’re on the newest versions of CM you can alter it to suit your machine. I increased my Z and Y travel in the settings screen to maximize them.

Note that it is possible to increase X-axis travel if using an HDZ w/o a dust collection system which limits X-axis travel.
