I've tried two different cables and two different computers- Max OSX and Windows 7.
The cable thing seems unlikely as I am connecting no problem- it always connects - but it's when asked to home and the thing starts physically moving that it crashes. I have tried securing the cables - no change.
I favour a physical impediment that is stalling the motors then it is disconnecting as a safety issue.
I will play more tonight even though it looks like glorious clear skies (again!!
)
Will keep you posted
(either that or I will be getting my cgem back out)
