Re: [Emc-users] Problem on EMC2 starting with rtai_hall.ko
your base period and those timings need adjusted to a higher number, the
computer isnt able to keep up with the speeds the configs are trying to
run. these are in the stepper_mm.ini file.
this talks about using the latency test to set the timings.
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TweakingSoftwareStepGeneration
I do not think so,
I tested it on phisical machine with Intel Core2Due 2,66. It is very fast
computer.
Another information.
If I build RT linux, reboot, build libraries and emc and start emc without
rebooting, then first start works properly.
On second and other start I have rtai_hal.ko problem or adress in use
I have not more ideas.
Only one idea.
Maybe prblem is then puppy linux has only Root user ...
Evgeny
P.S.
Thank you for you help

You don't consider real machining this way, do you? Dirk By the way I prepare EMC2 for small computer (No cooler, no HDD, small size). I try to make distrib on VMWare, before installing on real computer. Евгений Александрович wrote: I do not think then VMWare is a problem. Linux does not know than VMWare is not real machine. May be only unstable CPU resource ... I think Dirk has it correct. Even if it would work - VM will be pulling interrupts in background and the whole reason of using a realtime kernel is to prevent interrupts. If the machine was fast enough and the demand was low enough, it is possible you could get away with it, but for safety and sanity it pays to keep the computer controlling movements as simple and unencumbered as possible.
