摘要： An automatic mechanical spool changer for 3-D printers includes a filament guide and a pre-loading device. The input to the filament guide receives at least a primary filament from a primary spool and a secondary filament from a secondary spool. The output from the filament guide connects to an extruder, and the output from the filament guide sequentially and automatically provides the primary filament and then the secondary filament to the extruder. The pre-loading device exerts a pre-loaded force on the secondary filament during the extrusion of the primary filament. After the primary filament passes a predetermined location within the filament guide, the force exerted on the secondary filament threads the secondary filament through the output of the filament guide and into the extruder.

摘要： A method for ensuring safety critical functionality for a laser engraver includes obtaining a command from a laser motor controller; obtaining sensor data from a plurality of sensors, the sensor data corresponding to an operating status of various components of the laser engraver; determining a functioning status for each component; and as a result of determining the functioning status for all of the components, enabling supply of power to a laser, where the method is performed by a safety controller that is embodied in hardware completely separate from hardware in which the laser motor controller is embodied. One example required functioning status is that a power button has been selected twice in quick succession.

摘要： A table saw includes a table assembly having a top surface, a cutting assembly, and an adjustment assembly. The cutting assembly is arranged below the table assembly and is movable relative to the top surface. The adjustment assembly includes an input member connected to a first gear and an output member connected to a second gear and to the cutting assembly. The first and second gears include first and second gear bodies and first and second pluralities of pins projecting from the gear bodies. Rotation of the input member causes rotation of the first gear about a first axis, and rotation of the second gear about a second axis causes rotation of the output member which causes the cutting assembly to move. The second pins engage the first pins in such a way that rotation of the first gear causes rotation of the second gear.

摘要： A 3D printer for synthesizing objects includes: an extruder configured to extrude layers of filament through a nozzle onto a build surface; a build platform; and a build plate that is structured for being removably clamped to the build platform and that includes the build surface, where the build platform includes a base, a heating layer, at least one compressible biasing element arranged between the base and the heating layer, and a clamp, and where the build platform is configured for receiving the build plate into a clamping position in which the clamp is configured to releasably clamp the build plate onto the build platform above the heating layer, causing the at least one compressible biasing element to compress and bias the heating layer upwards towards the clamped biasing plate for even distribution of heat by the heating layer over the planar extension of the build surface.

摘要： A table saw includes at least one stop mechanism for setting or recording a position of a guide assembly on the table saw. The stop mechanism has a base member and a blocking member connected to the base member. The base member is connected to a guide structure on the table saw in an unlocked state and a locked state. In the unlocked state, the base member is infinitely adjustable relative to the guide structure along a slide axis. In the locked state, the base member is fixed relative to the guide structure. The blocking member is moveable relative to the base member between a blocking position and a bypass position. The blocking member in the blocking position is configured to contact the guide assembly and set or record a position of the guide assembly. The blocking member in the bypass position cannot contact the guide assembly.

摘要： An accessory for a power tool includes a blade and a coupling. The coupling includes a blade portion, a tool portion, and a transition. The blade portion is fixedly coupled to the blade. The tool portion is configured to be removably coupled to the power tool. The tool portion also includes an opening. The transition extends between the blade portion and the tool portion, and the transition includes a first transition region, where the transition intersects with the blade portion, and a second transition region, where the transition intersects with the tool portion. The first transition region includes a first arc having a center that is arranged between the first arc and the opening, and the second transition region includes a second arc having a center that is arranged between the second arc and the opening.

摘要： A table saw includes a working surface and a rail system. The rail system includes stationary rails mounted along the working surface, and extension rails. The rails each include matching guide surfaces extending along the longitudinal axis and configured to support and guide a rip fence. The rails have a common connection interface that in each case includes a connecting end and a supporting end, such that the extension rails are mountable with the stationary rails. When mounted, the guide surfaces of the extension rails extend the guide surfaces of the stationary rails. The connecting end in the common connection interface includes a connection mechanism configured to urge the connecting end together with the supporting end to form an internal connection, and to align the guide surfaces of the connected rails to as to be co-planar with each other.
