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!

Our CNC Mill

our new cnc

We have a real CNC Mill as of January 2015. It belongs to Pam and is on-loan. It is a myDIYCNC link cnc thing

Problems: For some reason, LinuxCNC thinks "home" is at 5.5", 0", 0" which is not where I would home it. I put sharpie marks to indicate the center of travel for X and Y, which is 6.0",3.5". I set the proper numbers in the configuration but it doesn't do what it should. Whatever.

You need to boot the computer to the LINUXCNC operating system, not the Ubuntu 14.04 installed by Big Ed

The USB adaptor it came with is total garbage, and the software offered by "my DIY CNC" is proprietary, so it is plugged into the parallel port of a desktop computer instead, and we are using LinuxCNC software as seen here: http://www.linuxcnc.org/

We'll be learning how to use this and adding more documentation here.

J using our new CNC - isn't it cute? Hope we can get more folks started on machining

The Past

  • JacksMill In the past jack lent us his CNC mill which we used to cut wood. It was at the old SudoRoom. It is no longer at the SudoRoom but it left behind some awesome memories.
