Re: [Emc-users] What current ITX board?
Anders, While I cannot comment on how it works I just recently bought a brand new Intel Atom motherboard from Newegg.com on the recommendation of two other users who have functioning machines that work well with them. I have yet to install and test it out as I JUST received my ram order yesterday. However my two friends and several other folks apparently have been using this board with good results. It apparently tests well in the latency area and is pretty good for a LinuxCNC conversion. It does have only one PCI slot but it has a parallel, and serial as well as several USB ports on it. Here is a linkpeace http://www.newegg.com/Product/Product.aspx?Item=N82E16813121442 Hope this helps and good luck man.

Re: [Emc-users] What current ITX board?
Since LinuxCNC doesn't really support 64bit that is kind of a moot point.

I've been looking for a smaller monitor with better brightness that I can mount over the lathe head, I've have a lot less crick in the neck after running the lathe as the only place to put that big honk is on top of the tool cabinet, itself about 64 high, so I am looking up at about a 40 degree angle.

With a 24 screen connected through HDMI the default 12.04LTS install uses a driver where the mouse cursor is flickering and graphics is obviously slow (e.g. just dragging around windows, browsers, etc the screen update while dragging is sluggish). It might be just barely usable, but it's not very nice. Googling for other linux experiences with the DN2800MT seems to turn up a lot of problems and frustration - so it's probably best to avoid boards with the cedarview graphics. Also, I have yet to run a program that obviously runs better in 64-bit versus 32-bit Linux. Is 64-bit really a criterion for you? Not really. I have been using 64-bit installs on laptop/desktop for general work for many years now I think. My desktop does have 16GB of RAM and the laptop 4 or 8 GB. For linuxcnc use 32-bit is probably fine.

Anders Sorry I went off on a big-board tangent; I saw ITX and thought ATX. This mini-ITX DH61AG board likes much like an unbundled Atom board would. It meets my half the price benchmark! I admit over the years I've bought several all-in-one Atom- or Via-based motherboards (the latter not for LinuxCNC) for their sheer convenience. Despite that, I prefer picking mixing and matching the CPU and motherboard because of the increased flexibility. I can swap out CPUs as my hacker interests change. I just asked an Intel site for a list of compatible processors for the DBH61AG board. It looks like with a third-generation i3 CPU you can get into the mid-30w TDP range (http://processormatch.intel.com/CompDB/SearchResult.aspx?BoardName=dh61ag). I seem to recall that Ubuntu 12.04LTS, and perhaps even 10.10, has suitable graphics drivers. And never feel like apologizing for an x86 solution. It is still the sweet spot for LinuxCNC.

Re: [Emc-users] limit override question
Thanks to everyone for the advice. Home/limits are working properly now. My primary issue was that I had mis-configured the system so that after a home operation in the positive direction the machine thought it was at the negative soft limit, thus it would not let me jog off the hard limit even with override limits checked. Fixing this allowed the override limits to work properly. Now I can home the machine and can't jog to the limit switch either way. This does work very nicely. Thanks all!
