Dwell/MROF
Hello mate
If you`re not having any problems ,IE smashing/chopping paint leave it alone if you are then set dwell at 14 and try that mrof is best set to the maximum your hopper will feed ,same as the last guy said really ,why do you ask ?
if you are having problems it wil not always be down to Dwell /mrof, let me know and if I can help Iwill
