Post by Sarah Armstrongjust a reply on progress ,
i am getting to the point of running and it looks as if the latency is
so high , i cant even start linuxcnc
That is often a trademark sign that the video card is an NVidia, and that
you are using the NVidia driver, which ties up the IRQ for as long as
100 milliseconds at a time and makes the machine worthless for LCNC
purposes. Using the vesa driver, which limits the resolution, might
work and would confirm my SWAG* about the video card holding you for
ransom
While I have one in this box, I'm only running the sim here, and using
the nouveau driver which although the graphics are gaming speeds, plays
movie and news story's off the net well. But the sim still reports
servo-thread times above a millisecond in the terminal its launched
from. Not enough to affect the sim, but this old Asus M2N-SLI Deluxe
couldn't get past a latency test on a bet, its just not suitable for the
real thing. Good board otherwise or I would have binned it long ago.
Post by Sarah Armstrongi'm also having problems with the graphics card not wishing to work in
graphics mode , only in software , so giving an even higher cpu load
this is on an amd64 ( using i386 os ) motherboard that up to now has
ran Linuxcnc for the last 3 years .
I run my older machines, a 7x12 lathe (ball screws and steppers) and the
small HF toy mill (ball screws, bigger tables and steppers) on atom
boxes, the toy mill still using software stepping but a 5i25 card would
speed up its rapids, currently limited by a 27 u-s base thread, and only
a 28 volt supply for the steppers.
My newer mill I've been talking about, a grizzly G0704 has higher voltage
and is currently being run by an off-lease Dell 745. With a 5i25, its
on-board graphics are more than adequate for the job. These are
available locally with 4Gb of ram, sans HD so he gets to keep the
winderz license, at $140. A small commodity HD, a 5i25 card, and its
all set.
Those D-525-MW atom boards that were nearly ideal for an economical
software step setup, have been discontinued for about 3 years, and the
last one I saw on ebay was selling for 4x the boxed OEM price. So this
Dell 745 setup looks quite attractive in comparison.
I might pay to visit your local computer guy and see whats there as there
were a kajillion of those Dells sold to businesses that replace them as
they are amortized on the p & l tax forms. No PATA sockets on these
mobo's though, all SATA. A floppy and a DVD r/w seem to be std
equipment. So a LCNC install is a 20 minute or less job.
Good luck Sarah.

Post by Sebastian KuzminskyPost by Alec AriWhich IPIPE revision is this? There are a few key difference
between IPIPE releases and it'd be a smart idea to somehow
integrate the IPIPE kernel release into the deb package version or
release notes somewhere. That way people don't need to go to
/usr/src/rtai-kern-source/arch/x86/include/asm/ipipe.h and grep
for IPIPE_CORE_RELEASE
Good idea, i'll add that to the package Description.
The the linux-image-3.16.0-9-rtai-686-pae kernel (version
"5linuxcnc") uses the hal-linux-3.16.7-x86-5.patch from rtai
Vulcano, which is based on IPIPE_CORE_RELEASE 5.
