For my machine (the one I don't have yet) here is what I have to do (theoretically):
from eq (in the stitching window) click on stitching/export stitching file
choose brother (pes) from the drop down
save it
connect the machine to the computer
find the file (documents/my eq7/emb)
copy the pes file to the machine
OR use a different program (probably ped basic, in my case) to transfer the file to a card and then put the card in the machine.
