[Emc-users] Broken software link
One of the fellas on the CNCzone forum is trying to download the Hardy Heron (8.04) version, and when you click on the link: http://www.linuxcnc.org/iso/ubuntu-8.04-desktop-emc2-aj13-i386.iso You get a: Forbidden You don't have permission to access /iso/ubuntu-8.04-desktop-emc2-aj13-i386.iso on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. The EU mirror link works okay though. mark -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Emc-users] Axis Gui will not run
Dave Keeton wrote: Jon, Thanks for looking into this but I have it working now. By the way, The Axiom card is a Digital I/O card supported by HAL. I was kind of surprised that everyone assumed that it was a video card. Whenever somebody has an Axis no longer runs on my system problem, that is the first thing that comes to mind, either video card or the drivers for it. The card is the Axiom AX5214H as described in the Linux CNC Docs. The problem was caused by an ATI Video driver that was not removed when I pulled the old video card out a while back.(Long before the DIO card was installed) Don't know why it caused a problem after the DIO card was installed but removing the old video driver corrected the problem. And, so, it WAS caused by a video driver, just that this had nothing to do with the Axiom card. Adding the Axiom card caused the PCI enumeration to move various cards to different addresses, and it may be that the Axiom card ended up at an address where the video driver was expecting the ATI card. Really, a driver should NOT remember a past address, but who knows what schemes a driver writer might use. Or, it could have been a startup script that was associated with the ATI card. Yes, if you don't give enough detail, we have to make some assumptions, and those can easily be wrong.

You still get a suction effect, so he slides the model over to a region where the floor is lower, breaking the suction. This apparently avoids any patent infringement. The reason for projecting through the bottom is so you don't have to fill the entire vat with expensive resin, at several hundred dollars per liter.

The advantage of this over FDM/FFF (reprap style) is that an entire layer of arbitrary complexity can be built in parallel, and at about 8-10 seconds/layer.

Although I should have realized the problem was video related because Tkemc ran, I knew that Axiom doesn't build video cards, so I assumed it either wasn't video or it wasn't the axiom card. This still seems really weird to me, it seems like the proprietary software that the video card companies are putting out is really bad nowadays. I'm happily avoiding it with my desktop. I had installed some proprietary Nvidia software on a previous installation of Ubuntu, and that same system was horribly unstable. I think it's intuitively obvious that a computer used to interface to the real world shouldn't have a lot of unnecessary software installed, but apparently this isn't obvious to everyone. One of the grad students was complaining that his computer was slow, I uninstalled all the extraneous software on the system and it sped right up. I think the main culprit was the software that only allows you to remain logged in to facebook for less than 4 hours.
