Rich, I know I need new nuts, and have compensated for the backlash already, but if I start right at the material height Z at 0.0000" by the time I get done with the project it is up from the surface of the material, so that tells me that the backlash is not this cause, because of gravity, it's loosing steps as I run it. I'm going to try slowing it down, which I'm still a little upset at the slowness already, I thought it would be faster.
as for the file, there is HUGE differnces, the origanal file is only 41.4KB were the new Easy3Mill file is 141KB
Yes I ran the driver test, my computer is ONLY for this machine, the only program on it is the Mach3, I'm not even on-line with it, and the driver test is as perfect as anyone could ask for
OK, clarification, on the V-Ref settings I have changed from 2-4V to get the different Amps to the motors, 4 is the max, 2 is the conservitive so my driver board wouldn't heat up too much
