Makerbot gen 4 machine

has anybody generated their own start/end scripts for a makerbot gen 4 machine, I'm not having a lot of luck on this
i have an Ultimate TOM built by Jetguy, I've tried copy and paste out of maker ware and writing my own
and so far not great results (actually some bad results) :D
