Hi,

Thanks, I think I have it sorted at last. When I first entered the valuse
from your .ini file Ray, the machine just went black and rebooted itself -
most unhelpful! But, after about half an hour of messing with the file and
repeatedly waiting an interminable time while linux checked the hard drives
during reboot, I managed to get it so that the machine just locked up!
Progress....
Of course, I still had to reboot each time and wait while it went through
the checking drives bit but, at least, I felt a bit more in control. It took
another 3/4 hour or so to get things stable and a further half hour to
calibrate the settings so that a commanded move of 100mm now moves 100mm
(well 100.02 to be exact but I've yet to tighten up a bit on backlash which
might make a difference)
Is there any way that EMC can be made to simply report errors (like 'Setting
out of Range') rather than simply dying and taking the computer with it?
