Re: [Emc-users] Linuxcnc on Fujitsu Siemens FUTRO S400
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 . I have found some paragraphs about and I have understood that is not a copy only procedure. Some more details ?

LinuxCNC has a built-in software PLC, but the question would have to be what the LinuxCNC part is adding to the system.

[Emc-users] Advice needed
Hello all I have an old beam saw that I need to replace the control on. It's all digital IO. Would LinuxCNC be a good idea for this running as a PLC? I was thinking of using this as a text to get to learn LinuxCNC for when I need to do a CNC router. If this will work, where do I start? -- Ethan Vos Cutting Edge CNC 339 Fairway Garden Newmarket, Ontario L3X 1B4 416-457-9119 www.cuttingedgecnc.weebly.com -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Test
It is quite mysterioso. I've noticed the same occasional failing on a couple of my (other) listservers (not sourceforge).

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 ?

Re: [Emc-users] Rewiring the BP
I was in a plant and the maintenance guy was bitching about blowing up a plc he just hooked up and I asked him where he hooked it up... he showed me where the breaker was and it was on the 277 lighting circuit of a 3 phase panel.
