Will do… So far I haven’t been able to make it work yet, so there’s a plus for WalkOVR… 
Setup was so much easier on the WalkOVR (the calibration sequence on the KAT Loco kit is a bit annoying since I’m doing it in another room and have to remember the steps as walking back and forth during calibration between monitor and play space will screw it up (fail).
Calibration is done after memorizing the steps, but no movement in Boneworks (which should be supported, I guess).
There’s absolutely nothing about the options in the manual, so there’s another + for the WalkOVR though only a small one as settings defaulted to non-working too… 
EDIT: Just noticed there’s a “Installation and first use video of KAT loco”:
EDIT2: Doesn’t show anything regarding the actual setup, so I’m unsure why it doesn’t work. Maybe I should redo the calibration again. Also noticed on their page that there’s a SteamVR dashboard for the KAT Gateway software which is cool, so I’ll give that a go while in-game…
