The issue tracker is not a support forum

Here are the steps I follow to reproduce the issue:

1. compile 5axis kinematics
2. run configuration
3. home all axis
4. move machine a little bit not to get joint limit errors
5. move B axis in “+” direction works fine
6. move B axis in “-” direction – silent stop, no error, just machine power is toggled automatically

This is what I expected to happen:

move in B- direction

This is what happened instead:

machine power is toggled, no error message, nothing

It worked properly before this:

before upgrading to 2.8.0-pre1 from 2.7.8
