[Emc-developers] 64-bit LinuxCNC w/ RTAI (working)

2013-08-17 Thread Alec Ari
Hello everyone! I have LinuxCNC master branch working with RTAI on a 64-bit 3.4.58 kernel. Latency-test runs fine and the demo sim works nicely as well. The makefile in LinuxCNC only compiles with this following patch that I mocked up when using 64-bit RTAI: http://pastebin.com/TEZwMLYz Any

2013-08-17 Thread Michael Haberler
I concede a fix is needed - I still would like to see a clean solution eventually, at least conceptually. LinuxCNC is not to first control where the requirement for more flexible arrangements than just coord mode (all joints) or joint mode (per joint) moves pops up, so let's see how other

[Emc-developers] Xenomai 32

2013-08-17 Thread andy pugh
This is a strange one. Running Ubuntu 12.04.2 LTS (GNU/Linux 3.5.7-xenomai-2.6.2.1 i686) The PC will boot in normal mode, but with no video. This is an Intel GMA PC (DN2800MT) so some wierdness is normal, but with the generic and RTA kernels the problem is just that the system fonts are unusably

I think the extruder needs to be an axis in that it is something that performs coordinated moves along with X, Y, and Z, but I also think there is room for it to be a non-traditional axis. By which I mean the gcode value (which represents the amount of plastic to squirt) doesn't need to directly

[Emc-developers] [DISCUSS] Proposal: Drop Hardy support

2013-08-17 Thread Schooner
Continuing to support Ubuntu 8.04 is fool_hardy_, and I propose we stop. No pun intended I assume! - AFAICT, there is only a very small handful of users still running LinuxCNC on Hardy. I'd wager that those users are quite conservative, and aren't interested in new features for LinuxCNC

I would have to agree, that hardy support should not be dropped. We are dealing with machine controllers here, not merely consumer PC's that *have* to have (or so people seem to think) the latest everything every 6 months or sooner. It makes sense to me to not force people running good stable

It makes sense to me to not force people running good stable systems on older hardware to have to update the whole OS - which might not run as well or have as good of latency etc - just to get bugfixes and newer features. FWIW, My router table is running Hardy even though I put
