UGS grinds very badly Easel works fine

Hi all,

I have just upgraded my X-Carve to screw drive, the machine seems to be setup well, certainly works fine in Easel. However when I try to use UGS it seems as if it is firing off each step and micro-pausing rather than running a continuous stream of commands. For the life of me I cannot work out why the same machine running the same FW behaves on Easel but not at all on UGS???
