    Where do I change the min_z (or @min_z)? I want to cut 2" foam, but the Z gets limited to -1.4. Here's the gcode. Thanks!!

    I found min_z in the constants.rb file. All is well again. :)

    No, all is not well , modifying Constants.rb will be overwritten everytime you upgrade.

    You need to change it via the menus to properly change the defaults.
    Click the big blue question mark in the toolbar.
    You will see this:

    now click the red text that says 'After install - things to do'

    scroll down a little to see:

    There is a lot of useful information in the help that will get you going much faster than asking on the forums.
    Knowledge is power, RTFM!
