dot/click the axis, click touch-off and enter the offset. If touching a 10mm shank, and in a metric mode, enter 5.0000 or -5.0000 depending on which side of the 10.0000mm shank you are touching. Note that this applies to the motions the machine makes, but has no effect on the actual limits set in the .ini file for that axis as all that is referenced to the g53 master co-ords set when the machine was homed. So barring loss of steps in a stepper setup you will hit the soft limits at a consistent mechanical position, but the DRO when it stops at the limit will be off by however much you have touched off that axis. You can see this a bit clearer in the backplot by enabling the envelop visual, it will not move even if you touch off to +10 at the 0.0 home position. That red line indicates what the machine can reach based on the limits set in the .ini file. Now, I do not have a single servo'ed axis despite useing some of Jon's pwm-servo amps for spindle motor drive, so I have not analyzed that for a servo driven system, but I'd fully expect it to be the same in actual mechanical function. > > - slide the piece in the jaws until it touches the 10mm shaft.
