PETG Stringing After Switching to Simplify3D 5.1 on Ender 3 V2

[markcowell]

Hi everyone, Mark here. I recently updated to Simplify3D 5.1 and started noticing something odd with my PETG prints on my Ender 3 V2. Before the update, my profiles produced really clean results, but now I’m getting noticeable stringing between small features even though my retraction settings (5mm at 45mm/s) haven’t changed. I’ve tried lowering the nozzle temp from 240°C to 230°C and increasing travel speed, but the strings are still there. Has anyone else experienced similar behavior after updating, or found a good setting tweak in Simplify3D that helps reduce PETG stringing?
