CNC

CNC Mill or computer numerical controlled milling device is used for automatically milling or cutting away at materials like wood, plastic, or softer metals such as aluminum based on a 3D computer model.

Akin to a 3D Printer, the CNC provides the ability to work with objects in x, y, and z dimensions. However, it provides subtractive manufacturing, rather than additive.

The sudo room sign by the intercom at the old 22nd st entrance was milled on such a machine!

The Noisebridge wiki contains much knowledge about using CNC mills for example TO MILL CIRCUITBOARDS: https://noisebridge.net/wiki/MaxNCMill#Toolchains

• JacksMill Jack gave us his CNC mill which we used to cut wood. It should also be able to cut soft metal like aluminum. It is located at the west wall, next to the robot control cabinet.

a large CNC machine we have hidden under a table

there is a large CNC machine suitable for soft materials like soft wood and plastic (and possibly harder materials?) located under the table in the southwest corner of sudoroom. It's made of wood and acrylic, and the wood is painted white.

When plugged into the USB of a computer, it presents as

/dev/serial/by-id/usb-Arduino__www.arduino.cc__0043_7533531343735110F120-if00

Connecing to it at 115200 baud, when pressing the reset button it says this:

Grbl 1.1f ['$' for help]

It runs GRBL firmware.

a cnc we thankfully no longer have

We had a small CNC Mill as of January 2015. It was donated by Pam and was traded away for a Quick Circuit 5000 (in the 3D printer area) It was a myDIYCNC link cnc thing
