hello hood
i ran into the xml problem today too.i keep a copy of my profiles on a zip drive to keep them safe.
when i did the install of mach3.0 today,it was realy clean.i wiped everything old out,even went through the registry.
did the new install, loaded my main profile when i started mach and when i moved the table the motors ran rough.
went to motor tuning and sure enough pulse width and vel were change.set them back everything ok,so far.
then i loaded my other 2 profiles to try them,and it changed both them too.each profile had a differant pulse width setting.
now after loading them a few times they seem to stay unchanged.
thanks bill
