Vertical Hop - How to Define?

I tried to define straight vertical hop before moving when not extruding. Minimun Hop Angle is 90. However straight vertical lift doesn't work.

What do you mean it doesn't work? What are the symptoms? What is the setting for your hop height/layer thickness ratio?

Finally, do you really need this? Most people have this turned off.

It lifts Z but not straight vertical. While lifting Z it moves X and Y coordinate to next extrusion point at the same gcode.

Ratio is 0.5. Lift height is correct though not straight vertical.

Yes I want it. Otherwise my nozzle tends to hit the model.

So you,re only lifting half of your layer height.

I have no idea why 90 degrees isn't working. That's exactly what the doc says to do.

I checked the gcode. Seems that there is an "extra hop" at the end of the line where it should be in the beginning (see below).
