Nope well I tried to make another box today more fire wood, still messing about motors got quite warm so think I might drop the voltage a bit. So checked the PC its running xp pro service pack 2 barely any services switched of all networking as well as its in my workshop, anyone any ideas? motors (mainly X but not exclusively) sometimes just squeal instead of moving until the next line of code is sent then moves on to destroy the work as its in the wrong place now. Cant think whats left to check slowed it right down as well low acceleration speed etc. HELP!
