How to jog when beyond soft limits

I have soft limits on my axis and absolute encoders. If I power off the machine when I am on the limit (max or min), the machine may move by a 10th (0.0001) or so, once the servos release on power off.  This will cause the machine to "move beyond" the soft limit, even if just 0.0001.  Once this occurs, I can't jog the axis at all.  I have to edit the limits in the ini, jog and reset the limits back. 

I would expect you can jog toward the soft limit and beyond to get back into the limits.  How can I jog into the limits is I am just slightly over (but over)

Probe Basic

Not sure what you mean by tandem axis/joint. It's a mill so three axis, defined with axis_ and joint_

To that point, the issue is both before home and after, so joint and axis.

I see in WCS, there are limits override, but maybe it only works with hard limits and limit switches?

Don't, just do not double post, it will not help you and will make a mess for us trying to keep stuff clean here.
Much better to post more info about your machine and how the homing is set up, and uploading config files usually helps a lot.
