Hey @3Dken So as you are finding PETG is a bit tricky to print with and for the most part it is going to be rather difficult to stop the stringing. I would say that the best bed to is keep playing with the Retraction speed/distance in conjunction with lowering your nozzle temp a bit. After that I think it is best to adjust the fan speed settings for the part cooling fan. You can always upload a few pictures of the issues you are seeing and we may be able to spot out something and advise a bit further. Thanks!
