Title: Problem with soft limits settings.
Post by: DICKEYBIRD on January 29, 2021, 08:45:41 AM
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.
