Did you configure for the correct Z-axis?

Setting Grbl Configuration in CM 517 and later

Carbide Motion 517 uses a new system for setting Travel Dimensions which is potentially confusing: [image] Pressing the Load Defaults button takes one to a window which allows one to select first machine size: [image] and then Z-axis type: [image] after which selection the Travel Dimensions for the selections made are entered into the dialog and will be preserved if one clicks “Ok” (and of course that change discarded if one selects “Cancel”). In addition there is a “Send Configuration…

If that doesn’t help, let us know at support@carbide3d.com

Many times when someone gets a probe error it is not the BitSetter but the BitZero magnet is grounding. So check that your BitSetter magnet is not contacting something on the machine or the BitZero. The two devices are tied to each other internally.

Also as @WillAdams Will suggested check your config. The Z axis has two choices for the Pro XXL. The HDZ is refereed to as ball screw and the Z-Plus is refereed to as the lead screw. If you initialized ok then it may not be the Z axis because the HDZ and Z-Plus travel in opposite directions. Just make sure you are using the latest Carbide Motion and pick the Pro XXL as your machine. Be sure to send the configuration after you choose the options. It is easy to not send. The Pro XXL has a Z-Plus as standard buy you could upgrade to the HDZ.
