CNC 1-01 Tiny steps


It might not look much, but on the table is the start of getting the Bridgeport converted to CNC operation. Nick brought his new motor and encoder round, fitted to a neat housing he made. I’d picked up an ODrive and old power supply, which we coupled to a Raspberry Pi. Igor kindly donated memory card and we were on our way!

By the time the evening was out, we’d managed to get the motor to turn through a fixed angle in either direction, run continuously at a fixed rpm, and apply a holding torque. Three critical operations for CNC. A great start, although there’s no doubting we’ve still got a long way to go.

Next steps are getting some beefier motors, fitting the odrive into a better housing and upgrading the power supply.

About Sophie Whiptank - aka Bart

I'm just a bloke doing some stuff, the more interesting bits I post on my blog. Scroll down far enough and you'll see me riding from Melbourne Australia to Birmingham, England in 2014. But now I'm working on another project, a single cylinder motorbike engine at 2750cc!
