I am having trouble getting soft limits to work on my little Sherline conversion.

The machine homes to what I think are the correct locations ie: X trips the switch & backs off a bit with the table at the far left of its travel.  That is then X-zero with table movements toward the right going negative; max safe mechanical travel is -7.5".  Y trips & backs off at its farthest (away from the column) point.  Table movements toward the column are negative, max safe travel is -6.15".  Z zero is all the way up; traveling downwards is in the minus direction.

First, is this setup "normal' for a regular 3-axis column mill and second, would someone suggest a configuration for the Home & Limits page?  I think the "Home Off." setting is what is  giving me problems.

Thanks for any input.

Google for

three finger rule or right hand rule

than you can see what is "normal"
