Abstract: A computer numerically controlled machine may include a source configured to deliver an electromagnetic energy to at least one location within an interior space of the computer-numerically-controlled machine. The electromagnetic energy may have a first range of wavelengths from a visible spectrum. An enclosure defining at least a portion of the interior space of the computer numerically controlled machine may include a transparent portion configured to filter the first range of wavelengths associated with the electromagnetic energy. Moreover, the transparent portion may reflect and/or transmit at least a second range of wavelengths from the visible spectrum not associated with the electromagnetic energy such that the transparent portion of the enclosure exhibits a first color corresponding to the second range of wavelengths.

Abstract: A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.

Abstract: A method of altering a rate of executing a motion plan by a computer-numerically-controlled machine can include: receiving, at a control unit of a computer-numerically-controlled machine and from a general purpose computer that is housed separately from the computer-numerically-controlled machine, a motion plan defining operations for causing movement of a moveable component of the computer-numerically-controlled machine; and altering, in response to a command received at the computer-numerically-controlled machine, a first execution rate of the operations to a second execution rate of the operations to change a rate of movement of the movable component. Systems and articles of manufacture, including computer program products, are also provided.

Abstract: A computer-numerically-controlled machine can include a light source and a housing. The light source can be configured to deliver electromagnetic energy to at least one location on a material at least partially disposed within the computer-numerically-controlled machine. The housing can include at least one side part surrounding an interior space and the at least one location on the material. The housing can include a structural material defining at least a portion of the interior space. The housing can further include a protective material protecting the side part. The protective material can reduce a permeability of the side part to the electromagnetic radiation relative to the structural material alone.

Abstract: A method for computer numerically controlled processing may include receiving configurations for a fabrication in which a computer numerically controlled machine processes a material to achieve one or more designs. An analysis may be performed to determine whether a thermal event occurs during the fabrication. The analysis may include performing one or more of a time-variant simulation and a time-invariant simulation of the fabrication. The thermal event may include one or more regions of the material exhibiting an undesirable response to the electromagnetic energy delivered to the material. One or more outputs may be generated based on the result of the thermal verification. The outputs may include a visualization of the quantity of energy exposure across the material, an alert if a thermal event is determined to occur during the fabrication, and corrective actions for resolving potential thermal events.

Abstract: A computer numerically controlled machine may include a source of electromagnetic energy. A beam of electromagnetic energy from the source may be delivered to a destination such as, for example, a material positioned in a working area of the computer numerically controlled machine. The beam of electromagnetic energy may be susceptible to interferences while traveling from the source to the destination. The computer numerically controlled machine may include a beam detector configured detect an interference of the beam by measuring a power of the beam of electromagnetic energy at a location between the source and the destination. An interference of the beam may be detected if the power of the beam is less than a threshold value. A controller at the computer numerically controlled machine may perform one or more actions in response to the beam detector detecting the interference of the beam of electromagnetic energy.

Abstract: 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.
