John, do your files have .xml after them, because mine do not...I did as you said and replaced the profile file
with a date that I knew worked...that file was in the XML backups location, but they did not have .xml after them...
they have .xb42, .xb43 etc. after them...so I copied one that worked and pasted it onto the desktop, then dragged it into the profile folder in Mach3...
then I changed it to read G540 Nema 23 2012-08-03.xml...then rebooted Mach3 and turned controller on but cannot get anything to move, X, Y or Z
nothing...I can hear the stepper motors running, but normally when I'd turn the controller on, I could hear a little jump sound where the router jerked
a little from the slight stepper movement...I don't hear that sound now because of the lack of communication of the software with the controller because of the
crazy ART error...it's funny that the error occurred after I had just completed a 12 hour project which came out perfectly...then when I shut down Mach3 the error came up...
normally I shut off the controller first before I shut Mach3 down...this time I did it the opposite way, shutting down Mach3 before turning off the controller, but doubt that was the reason
for the ART error
should I try to rename the profile file back to the name it was in the XMLbackups file...which was G540 Nema 23 2012-08-03.xb43?
