Greetings Andy,
Before I embrace major surgery on my machine, I had a thought.
I recently started adding G64 P0.001 to my programs. Prior to this, it defaulted to G61.
The machine crashes in what appears to be a G02 or G03 command.
Is it possible the G64 P0.001 is too fine and it is "confusing" the computer?
I have searched for G64 parameter limits with no success. i.e. what is the minimum and maximum value?
What happens if one programs a G64 P0.00001 ? I must add, that I am using Imperial units, INCH.
With kind regards,
David

I would say "no". A test would alnswer the question, but if the crash isn't reproducible then that is hard to do.
The numbers are all double-precision floating-point, so there are something like 15 significant figures of precision to play with.

Greetings,
Things have become worse.
The computer shuts down and on reboot, I get an invalid boot sector.
Bought a a replacement hard drive and installed LinuxCNC Debian. Debian creates an error message that it does not recognise my CPU. Also, the splash says it is Debian i686. I have an i586 (32 Bit).
While in Debian, I cannot access the Update Manager. I put in my password and the window disappears.
Tried to log on to LinuxCNC Forum via Ice Weasel; but, clicking on search kills the application.
Found a CD with LinuxCNC Ubuntu 10.04. Installed okay; but, update manager says software no longer supported!
What are my options? It seems my CPU is recognised by Ubuntu. Can someone point me to a link to download a Ubuntu LinuxCNC that is supported?
With kind regards,
David

You can run the latest released version of linuxCNC on 10.04 (Lucid Lynx) so I would suggest testing that first.
Maybe it is time for a whole new (possibly second hand) PC?

Greetings,
The machine has been running fine since my last plea for help.
I suspect a bad EIDE data cable as I totally removed the EIDE hard drive and installed an SATA drive that uses a completely different data connector and power connector. (The old data and power cable is custom made by Smithy, the machine's distributor.)
I have ordered a new adapter board that allows the use of a 2 1/2" EIDE drive with the "normal" EIDE data cable of which I have some spares.
I am glad that the machine is running again; but, it would be nice to know exactly what it was that I "fixed"
All in all, a good learning experience. I installed the operating system software (UBUNTU) at least five times and upgraded to LinuxCNC 2.5.5 from 2.5.4.
I also learned that I only needed my old *.ini and *.hal files to restore all my settings.
Cheers,
Dave
