When you’re running a Kickstarter for a robotic arm, you had much better be prepared to show exactly how repeatable as well as accurate it is. [Andrew] has done just that by laser engraving 400 wooden coasters with Evezor, his SCARA arm that runs on a Raspberry Pi computer with stepper manage handled by a Smoothieboard.
Evezor is rather an remarkable project: a general function arm which can do whatever from routing circuit boards to welding provided the best end-effectors. If this seems familiar, that’s since [Andrew] provided a talk about Evezor at Hackaday’s Unconference in Chicago,
One of the benefits for the Evezor Kickstarter is a easy wooden coaster. [Anderw] cut each of the wooden squares out utilizing a table saw. He then made stacks as well as set to programming Evezor. The 400 coasters were each chosen up as well as dropped into a fixture. Evezor then utilized a little diode laser to engrave its own logo together with an private number. The engraved coasters were then stacked in a neat output pile.
After the programming as well as configuration were complete, [Andrew] hit go as well as left the building. He did keep an eye on Evezor though. A infant screen caught the action in low resolution. two DSLR cameras likewise snapped pictures of each coaster being engraved. The resulting time-lapse video can be discovered after the break.
