Gmoccapy 4 axis question

Hello
I'm trying to retrofit a friends 5 axis machine (XYYZB) and I'm testing out the example config. The B axis on the nachine is mounted on the Z axis and I would like to visualize this. The thing is the example configs for non-trivial kinematics are based on rotary tables. The principle should work for this macine but I would love to make Gmoccapy show the tool tilting. Since examples use rotary tables the tool is mostly vertical and doesn't move (the table moves).
How can i change this?
Thank you
