Fast machines are badass. Simultaneously precise and fast machines are even more badass.
Shapeoko is already very cool; but wouldn’t it be awesome if it also went at ridiculous speeds? If you also think so, then maybe we can work together to create something next level!
Let me show you some progress I have made already:
This is a modified LitePlacer; the mechanics of which are somewhat similar to the X-Carve, at least when it comes to the rail system. It is retrofitted with 2kW brushless motors from Hobbyking, and a motor controller I made myself.
However, on this machine we are not able to get even close to the 2kW; the limiting factor is the 6mm GT2 belts, they jump teeth on the pulley if the motor torque is too large. Shapeoko is a much sturdier machine, so naturally it would be a good candidate for a more powerful performance.
I don’t have a Shapeoko, and its a bit too excessive to get one just for a fun project like this. Instead, I think this would be a great opportunity to team up and do a collaboration. Projects like these are way more fun to do together with someone else anyway. So if you are interested, then that would be awesome!
I imagine it will go down something like this: I supply the motors, controllers and motor control know-how; you supply a shapeoko, a sturdy table (we will need it), and shapeoko/milling know-how. We play some tunes, get pizzza, and through the course of a series of hack sessions, together we make something truly awesome. When we are done with the project I’m happy for you to keep it: I have a bunch of spare motors and controllers so I’m not too worried.
Primarily I’m looking for someone in the SF bay area, but anyone who is interested please join the conversation anyway!
