Major Stringing with Timer Trigger Only

Has anyone ever gotten the Timer Trigger(every 30 seconds) to run well without stringing? I am fine with all the other trigger but I love the idea of relatively flat multi-color time lapses where the image essentially is essentially drawn out of thin air. Everything works perfectly with the pauses and filament changes but I get so much stringing that I can't seem to get rid of. Seems to be fine in other trigger modes. I am using a Micro-Swiss NG Direct Drive.
