Hi All,
I am having issues with my small cnc mill. I teach at a school where we updated to new 64 bit computers this year. When I installed Mach 3 onto the new computer and used a UC100 usb controller. Everything has been working fine, until a windows update installed. I went to cut a 2D pocket out and in the middle of the process the machine plunged into the part about 1/2" when the plunge was set at .06" for each pass. It was totally random and the machine when reset worked fine until the next time I loaded a part. I set the z at .5" above the part to test it and when I did a MDI G0 Z0.5 z moved up to the top of the carriage and crashed. So I went to the settings page and tried to check the calibration of steps. When I selected X and move 1 unit the machine traveled the whole length of the table?
Motor steps are still what they are supposed to be, yet every time I load mach 3 when I first open the program movement is fine 1 to 1 ratio. Then when I load a file it wacks out and crashes. I have tried several files that have never had issues running and they do the same thing. Any suggestions would be appreciated. Thanks.
