I'm not sure what the config tool is in Axis but if you use the EMC stepconf wizard you should be able to make a new config and test each axis as you go. If you are using the stepconf wizard then you need to be more specific as to what you did, what you expect to happen and what happens. Hobbycnc does not provide clear information on step timing the best we have is here. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Stepper_Drive_Timing > > I figure this is probably something dumb I am doing, and I am willing > to RTFM, I just need some direction. > > With the sample config, it is jogging back and forth OK, but it is not > set for the right threads per inch for the lead screws. > > Once I get this working, next comes home and limit switches and a > hardware emergency switch. > > The latency test runs, but if I do try to use the computer, sometimes > the numbers go out of sight.

Jack If you have an onboard video sometimes that will give you problems. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting When the computer "goes crazy" don't expect the machine to remain uncrazy!
