Abstract: A method for accessing a computer-numerically-controlled machine can include receiving a command to be executed by the computer-numerically-controlled machine. A hardware state of a component in the computer-numerically-controlled machine can be determined by receiving, from the component, data indicative of the hardware state. An origin of the command including a user identification of a user who sent the command and/or a machine identification of a device that sent the command can be determined. Whether the computer-numerically-controlled machine is allowed to execute the command can be determined by applying a set of rules and based on the hardware state and/or the origin of the command. In response to determining that the computer-numerically-controlled machine is allowed to execute the command, the command can be executed at the computer-numerically-controlled machine.

Abstract: A method for dithering can include receiving, at a computer numerically controlled machine comprising a laser, a motion plan corresponding to a first image. The output of the laser can be dithered, in accordance with the motion plan, to effect a change in a material within an interior space of the computer numerically controlled machine. The change can substantially reproduce at least a portion of the first image on the material. The dithering can include providing laser energy to the material at a native resolution based at least on a spot size of the laser. The spot size can be determined based at least on one or more parameters of the computer numerically controlled machine and/or one or more properties of the material. The laser energy can be delivered at locations separated by a distance no less than the spot size.

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 calibrating a computer-numerically-controlled machine can include capturing one or more images of at least a portion of the computer-numerically-controlled machine. The one or more images can be captured with at least one camera located inside an enclosure containing a material bed. A mapping relationship can be created which maps a pixel in the one or more images to a location within the computer-numerically controlled machine. The creation of the mapping relationship can include compensating for a difference in the one or more images relative to one or more physical parameters of the computer-numerically-controlled machine and/or a material positioned on the material bed. Related systems and/or articles of manufacture, including computer program products, are also provided.

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 may include projecting, onto a surface within a computer numerically controlled machine, a structured light having a known property. One or more sensors may generate an image of the structured light projected on the surface within the computer numerically controlled machine. One or more characteristics of the surface may be determined by comparing a property of the structured light shown in the image to the known property of the structured light. Examples of characteristics include a size, a distance to the surface, a height, a thickness, an angle of the surface, edges, surface properties, jigs, fiducial alignment markers, patterns encoding data, and visual designs on the surface of the material that are intended for reproductions. A surface map indicating the characteristics of the surface at various locations may be generated to enable, for example, a calibration, alignment, and/or optimization of the computer numerically controlled machine.

Abstract: Disclosed embodiments include a head attached to a gantry. The head includes an optical assembly to focus a laser beam onto a surface of a material to be processed by a CNC machine and a measurement assembly with emitter(s) and detector(s), where the detector(s) are for measuring intensity of light emitted from the emitter(s) and reflected off the surface of the material. Processors are configured to (i) determine a material type of the material, (ii) determine a distance between the optical assembly and the material surface based on (a) measurement(s) of the intensity of the light emitted from the emitter(s) and reflected off the material surface, and (b) measurement parameter(s) associated with the determined material type, and (iii) control focusing of the laser beam onto the surface of the material based on the determined distance between the optical assembly and the surface of the material.
