An execution plan segment of an execution plan can be received at a control unit of a computer numerically controlled machine from a general purpose computer. The execution plan segment can define operations for causing movement of a moveable head of the computer numerically controlled machine to deliver electromagnetic energy to effect a change in a material within an interior space of the computer numerically controlled machine. The execution plan segment can include a predefined safe pausing point from which the execution plan can be restarted while minimizing a difference in appearance of a finished work-product relative to if a pause and restart are not necessary. Operations of the computer numerically controlled machine can be commenced only after determining that the execution plan segment has been received up to and including the predefined safe pausing point by the computer numerically controlled machine.

In a method for determining a deviation of a spatial orientation of a beam axis (S) of a beam processing machine from a spatial nominal orientation (S0) of the beam axis (S), contour sections (KA1, KB2) are cut with a processing beam into a test workpiece from two sides of the workpiece. The contour sections (KA1, KB2) extend parallel to a nominal orientation of a rotation axis (B, C), where the rotation axis is to be calibrated. The contour sections (KA1, KA2) are probed from one side of the test workpiece by a measuring device for determining the spatial position of the contour sections (KA1, KB1). Deviation of the spatial orientation of the beam axis (S) of the beam processing machine from the spatial nominal orientation (S0) is determined based on the spatial positions of the contour sections (KA1, KB1).

A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.
