hi, it´s me again
I am facing the same problem with another PC and I can´t make it work changing BIOS parameters.
When I load Mach3 everything works great. After I run the first Gcode the problems appears. Motor rattle in every axis.
I found a very strange solution, it si to deactivate the toolpath graphic display. I unchecked all options in the toolpath display settings and it work a lot better, near flawessly
I think the problem is related to the graphic subsystem of win7. I tried in using an external graphics card but it is exactly the same result.
Any tip?
Thanks in advance
Alex
