Gislain Benoit’s The Clock is an incredible piece of work. Imagine a world where electronics exist but integrated circuits were never invented. How would you make a digital clock?

In a recent post called Adapting Makelangelo CoreXY Kinematics I described in theory how to run a CoreXY system using the Makelangelo firmware.
Well Mike didn’t hesitate, he ran right out and showed it works!
This is how I feel about it:
Let’s take a virtual tour of the Italian factory where Arduinos are made.
I love watching videos of factories and automation.
Chris wrote in with a link to a great project I’ve wanted to see for years: closed-loop 3D printing.
An open loop machine run blind. anything pushes them off course and they won’t know it. In 3D printing this nearly always means restarting from scratch.
Closed loop machines are more self-aware (not in a Skynet kind of way!). They’re programed to correct themselves, meaning less failed prints.
Misan replaced the stepper motors in his 3D printer with DC motors that have optical encoders. The encoders sense how far the motors move. Misan can even force them off track mid-print and the machine will correct itself. Perfect!

Mike wrote in on our live chat to talk about his CoreXY kinematics. Seems there’s no open source Arduino code to drive his new system and – being a smart guy who does his homework – he reached out to the people with experience. Long time readers will know that I started a Jigsaw solving robot last year and that I intend to finish it in May. Seems like interest in CoreXY has just exploded since then, and this was a wake up call.
With the changes described below you should be able to draw images using the Makelangelo software on your CoreXY system. Video proof, too!
