This driver has an integrated simple controller, and offers output current ranging from 0.2 to 2.5 amps/phase with step resolutions from full, 1/2, 1/4, and 1/8. It can be configured and controlled either by a simple RS485 communications bus or step and direction inputs. Different access codes can run multiple modules on the same bus. A non-volatile memory can save user-configurable parameters, and allow them to be restored after a power-down, power-up cycle. The R101 can be customized by Lin Engineering, including reprogramming the inputs for a keypad interface or re-coding the homing command to the index phase of an encoder.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
