Further to my last message , i proved the Y encoder and switch is operating correctly as i activate the homing switch and let it off when the table was in the middle.
So thats a good thing.....

But reading from the above........ .....how do I "grid shift parameter 508 for the Y axis. I would try to set this to zero "

How do we go about doing this ???

Thanks in advanced

The grid shift enables you to electronically adjust the zero point of an axis. For example by using a centre of table bore or bung, should read x/y zero on screen if swept from an indicator mounted in the spindle. Ie. Indicator X0 Y0 when rotated should show X0 YO in absolute position on the display. Adjust 508 if not, start with 508 at zero after writing down its value.
