So just tried to print again and melted the x-carriage, not sure if it was the bulldog or the Hexagon AO that caused the over heating (there is a fan running between the two but something overpowered it!) and its buckled the xcarriage so i can’t do anything now.

Not sure if the fan wasn’t working enough or the extruder overheated but the resault is a printer that can’t be used!
