 This functionality is not a substitute for common sense, nor is it able to protect the table in all circumstances. If the user does the following, this functionality will not be effective:
-)Reloads a new cutter and does not perform another safety touchoff. (The system will track automatic toolchanging across properly learned and identified tools, but can do nothing to help misidentified or mislearned or manually loaded tools)

Therefore, on manual collet spindles, it is best to perform a safety touchoff after changing tools, in addition to touching off Z zero again.

 The Techno CNC Interface Version 1.424.1 and newer has functionality to help prevent users from accidentally cutting too deep and damaging the table. This functionality requires the user touch off on the table or MDF sacrifice surface to prevent cutting these surfaces.
 To employ this function, enter Setup, Options and select the modes you wish to use.

 If the user wishes to restrict cut depth, enter a negative value. For instance, if touching off on the table surface, but employing 0.75" of MDF as a sacrifice board, enter -.735 to allow the system to cut into the MDF board by .015"
-Max depth cut(-) - This functionality is separate from the safety touchoff but is for similar purposes. The value put into the text box next to the check box represents the maximum Z negative depth allowed in a file, regardless of Z zero position or table protection position. If the file trajectory will lead past this value, an error will be presented.
