Re: [Emc-users] Linuxcnc on Fujitsu Siemens FUTRO S400
I have upgraded memory to 512MB replaced the 1GB cf card with a 16 GB card and installed linuxcnc 2.7.3 . On the latency test I got 49900 no jitter on servo thread and 25000ns on base thread. The test was done on heavy load , top was showing around 9 on 5 minutes. It is usable ? How can I transfer the settings for my MF 70 from my old 2.6 Linux CNc ?

Yes, the memory is tight , it is using a small amount in swap, I will upgrade to 1GB soon. Please indicate me where can I find a procedure to transfer the setting for my MF 70 from my old Linux CNC with 2.6 .

[Emc-users] Linuxcnc on Beaglebone for a small mill Proxxon MF70
Hi everybody, My name is Paul Lacatus and I am quite new on this list. I am using LinuxCNC for a few months on my Proxxon MF70 converted to CNC. Up to this moment I am using an old Pentium 1GHz for this job as standalone computer. . Right not the computer is bigger than the mill and on the work table the computer is occupying more then 70% with a display and keyboard. I have read something about the implementation of LinuxCNC on BeagleBone Black. I have available a BeagleBone white ( 720 MHz 256 MB ram) . My questions now : 1. Is this card strong enough for running LinuxCNC headless ? Or should I get a BeagleBone Black (1GHz / 512 MB ? 2. I need a display and keyboard near the Proxxon for setting and control . If I am using BBW can I use a Raspberry Pi for X11 server ? In that case running Axis can be overkill for BBW ( grafic acceleration is in Raspi ) ? 3. If I have already the driver board controlled by LPT port of the computer did I need and extra hardware of interfacing BeagleBone or a simple logic level conversion is enough.

(Not that I can recommend that, the RPi step generator doesn't actually appear to work properly). Or is there a strong reason that BBB installations have to run headless?

PS The BBW is just laying on my table ;) BTW Beaglebone is much easier to mount somewhere in the electronics cabinet The only thing that keeps me from using Beaglebone are the emails about hdmi and pru fight for particular pins, so there were some difficulties about them. I know that Charles has a working solution, but I do not know any details. Disabling hdmi and running the beaglebone headless is definitely a solution, but I know that I am not that advanced to set up something like that. the BBW that I already have has no HDMI but has also low specifications ( comparable with RasPi that I also have 720MHz Cortex , 256 MB ) than BBB . I am prepared to use it headless with X11 server on other machine . That why I proposed Raspi for an X11 server. I like Axis toolpath preview and I don't want to loose it ;). On BBB I heard That is a bridge cape that is solving the pin problems. Paul: Which are you---a machinist who wants to make chips fly or a computer enthusiast who wants to play with new hardware/software combos? Please don't think I'm being snarky. A machinist who wants a solution which just works would either stick with the oversize AT/ATX computer you already have or substitute a downsized, presumably Intel Atom-equipped microATX board with an onboard parallel port. The LinuxCNC wiki contains latency test data for some of these boards. The archive of this list contains messages about the headaches caused by the onboard graphics controllers of certain of these boards. If you're willing to use a RPi as the Xserver for a BBW then you should have no problem using it as well for any x86-based controller if the onboard graphics don't work out. I'm actually a great fan of separate Xserver terminals---what we used to call an Xterm, aka thin client, last century. The neat thing is, you can try this approach right now to see if you like it, using your existing LinuxCNC as the Xclient. A computer enthusiast, on the other hand, may well wish to wade into the ARM world. There is furious activity on several levels in the LinuxCNC community which tends to be reported in more detail on the companion emc-developers mail list. I'm at the periphery of the developers, helping more to test their work than to contribute to it. Impressive gains have been made and there are some striking results (see for example Charles Steinkuehler's YouTube videos of his 3d printing) but I'd have to characterize the whole of the work as not yet ready for prime time but real soon now from the standpoint of the common user. Not only customized LinuxCNC software but also customized capes/interface boards are emerging should you choose to play. If I had to compare the total cost of ownership (TCO) of the two approaches as opposed to the first cost of the motherboard, I'd have to say they are roughly equal, especially if one puts a dollar/euro/leu value on one's time. [Please, gentle readers, don't start an email storm over this observation. If you like, I'll restate it as all hardware approaches cost more than you expected.] Excellent point of view Kent. I am more a computer enthusiast than a machinist. In any moment I can use my existing old faithful computer for machining ( mainly PCB and front panels) . But I will try also the BBW that I already have . I will also check the Xserver /client solution with the existing setup ( computer) in different server implementations ( Raspi vs. computer) . Also your proposal of Atom board is very interesting. I'll have to find a Atom MB with parallel port for tests. Finaly i think that the old computer should vanish for this hobby CNC and has to be replaced by a smart embedded solution with a large enough touchscreen , a jog wheel and for sure LinuxCNC is the solution in front of windows approaches.
