Re: [Emc-users] PC MB for Linux.

Is the motherboard AGP 8x compatible? There can be issues plugging an 8x video card into a board with a slower slot. The AGP standard has provisions for backward compatibility but they were for the most part optional. Many 8x cards are 1.5 volt only, though some can tolerate 3.3V or 5V. IIRC

Re: [Emc-users] PC MB for Linux.

Has to be two different computers, right? For PCIe x1, grab a Quadro NVS 290 off eBay, preferably with the dual monitor breakout cable it'll require. Those come in dual VGA, dual DVI or one of each. You'll also find plenty of ATi FireMV 2250 x1 cards but the Quadro beats the pants off it and

I do that with both the Pi and another WIN-7 application. In fact that's how I run the 3D printer via Octopi. I haven't tried getting into this new machine. However, If I'm standing over the CNC machine it doesn't help if the workstation here with 2 1080P monitors is in another room. For

Re: [Emc-users] PC MB for Linux.

Why not just unplug the monitor, keyboard and mouse and run the system "headless". Then you don't have to worry about graphics. I'm sure you must own some other computer, the one you use to post here. Have your LinuxCNC machine use Ethernet to send the display to your other computer. That is

No luck. Pretty as the display is with the AGP 8x board, it seems to lock up something in the LinuxCNC part. Has anyone tried one of these with LinuxCNC?Name brand this time. Has HDMI, DVI and even VGA. https://www.newegg.com/Product/Product.aspx?Item=9SIA7HN5HW6133 John > -Original

Re: [Emc-users] PC MB for Linux.

While I was out and about today, after doggy walk, I stopped in at a local computer store that also sells surplus stuff. For $14.95 I picked up an AGP 8x generic video board. Installed it, BIOS came up knowing it was AGP. Linux came up with proper resolution. Sharp. Crisp. Then I ran the

Re: [Emc-users] Pine64 / Rpi3

Latency does not matter if the real-time timing is done on the "far end". N the case where you would use USB or Ethernet you'd have a processor, either an FPGA or a uP. If there is any kind of buffer or memory on the processor then millisecond hang-ups are OK. Proof that this works is with al

Re: [Emc-users] PC MB for Linux.

Hi, The Live LinuxCNC distro doesn't have or create an xorg.conf file. Other postings on the web suggest that this was disposed of in some distributions in favour of xrandr and/or probing on startup everytime. You're right though, it does appear like there is a default 1920x1080 desktop size.

Re: [Emc-users] Pine64 / Rpi3

On the Pi the Ethernet and USB are on the same shared bus. But how much bandwidth is required to drive a Mesa FPGA card? I have read the Ethernet port can only push about 40% of it's spec'd bandwidth but the card only requires 2% it's OK. If performance is the goal you's spend an eatery $50 and

Greetings everybody; It occurred to me later last night, that these following errors absolutely have to be bus or card failure related. The LCNC system has no feedback from the motors, only from the 5i25. So as long as thats working, I ought to be able to jog an axis at a reasonable speed

Re: [Emc-users] Pine64 / Rpi3

An Ethernet connected Mesa board seems like it would connect with any computer, pi, Intel PC or BBB. Ethernet is pretty universal. If you are worried about electrical power get an Intel Atom mainboard and install a PCI connected Mesa card. The Atom uses so little power it does not need a fan.
