Testing EMC2/LinuxCNC on Ubuntu 7.10 Gutsy
I just completed the first test of running EMC2/LinuxCNC on Ubuntu with the HobbyCNC board. I connected a motor to the X-axis and started EMC2 with the “Axis” interface. I then told it to execute the default G-code file it loads with. Lo and behold the motor started spinning! I then moved the motor to the Y and Z axis and repeated. Seems to work well.
I didn’t notice any stalling so the problems I experienced with Windows XP and Mach3 must be due to Windows XP…
Here is a video:
Details on how to install EMC2 from source along with RTAI will follow when I have them ready. Also I will post the configuration files for the HobbyCNC board a bit further on in the project when I have more confidence that they are correct.

Radio Controlled Aircraft for Stroke Victims
about 3 months ago - No comments
This post introduces my open source radio control project. It allows an RC aircraft to be controlled from a Wii Nunchuk, i.e. with one hand! Videos will be posted when they are available but so far it is working great in the flight simulator and with a stationary aircraft.

Change in Direction

I decided that the McWire CNC machine probably wouldn’t be able to product the accuracy I need, or have the lifespan that I need for a machine. In addition I want to be able to cut objects up to a square foot in size. The McWire design would need to be four square feet in
CNC Update
about 4 years ago - No comments
The project was paused for Christmas and New Year, now I’m wondering whether to continue with the McWire design or go with something else. I recently came across the Fireball CNC machine, which looks very nice. Each machine is hand made in the US, which appeals to me.
One of the early projects I wish to
Bearings

I’ve found what looks like a good source for bearings for the design. It’s Skate Bearings and they sell individually as well. Price seem very reasonable. If I can’t find a local skate shop then I will probably order from them.

Power Supply
about 4 years ago - 1 comment
The Yahoo group for the HobbyCNC boards contains a file which describes a linear, unregulated 10A power supply, suitable for driving four motors. This power supply converts 120VAC to 34VDC up to 10A. The circuit diagram is very simple, but a lot of additional effort and parts are required to construct a working power supply.

Part Design Tools and Workflow
about 4 years ago - 1 comment
After spending quite some time trying different pieces of software I have come up with a collection and a workflow that I think will fit my needs.
I wanted to be able to accurately design parts in 3D, see how the parts will fit together to make sure they are right, and produce traditional engineering drawings
Low Cost and Free CAD Programs

I have stumbled across a large list of low cost and free CAD programs, mostly for Windows however. It seems there are many good choices in the list and I will try out a couple in the next day or two.

Windows XP and Stepper Motors
about 4 years ago - 2 comments
My first test after assembling the board was to connect one motor to each axis in turn and test using Windows XP SP2 and Mach3. The test involved going to the motor tuning section and pressing the up and down arrows.
On the X and Y axis it was clear that steps were being lost. I
Basic Motor and Board Testing Completed
about 4 years ago - 1 comment
I have completed a basic test of the board and motors. The motors seem to miss steps even at a very low speed, and I think this is either because there is no load on the motor’s shaft or my laptop doesn’t generate the pulses properly (happens with some PCs). Here is what I did

Just ordered the hobbycnc board. I am a newbe and look forward to any info and help with
my new project i.e. getting it up and running. I shall be watching this space with interest.
I hope to use EMC2 with Ubuntu 6xx the live cd , I shall be installing it although I would prefer the later Ubuntu. By the time I get my board built and my gantry mill built I should think there will be a newer version of Ubuntu. Thanks for this bit of encouragement ” seeing is believing”
Thanks again
