hi think you are right but as i am new i am not sure what i need to change or to
i have found g-code using replicator g

if my understanding is correct if i access g-code using replicator g then alter settings for the bit you shown above then save it to actual printer then i should be able to use makerware and set printer bed leveling and all settings for position should already be saved ?

could you please advise some reference as to which part in your picture i would need to change to stop my printhead going approx 2mm less forward than it is for bed leveliing

i will try and get a pic of my code later and upload it here so you can see what i have at min

thanks for any help and info
