Hello, on a new Mach3/RnR Motion Controller/PTY-E1500/CNCEST 6040 setup, all stock no added limit switches or anything, I have successfully gotten the spindle to rotate up to speed. But I am having trouble getting the XYZ axis to move. As soon as I try to run from PC, the CNC jerks minutely, and then an error message "Limit Switch Triggered" pops up. Help very much appreciated.
