Hello i dont use limits. Or Homing for A axis.
My Range is -9999 - 9999
You can set up home search speed to 0. So linux cnc think A axis was himed.

No luck. In stepconf on the A setting page the last three lines to enter search speeds are NOT grayed out but the values cannot be entered or changed.
using V 2.7.15 Being 75 years old doesn't help. I know nothing about Linux but enjoyed Linuxcnc. I have been away from cnc for about ten years and trying to improve my hobby of using Linuscnc. Carl

Still no joy. I have it back working on 3 axis so I can use it. I have downloaded version 2.8.4. When my hair grows back I'll update/upgrade. Thanks anyways. Carl
