Bridging issue with CR-10 V3

Hello, I have upgraded the hotend on a CR-10 V3 with an all metal V6 clone from TH3D Studios. While attempting to dial in this setup, I have run into a big problem with bridging. With Atomic PETG, the behavior is:

  • On the layer with the bridge, the extrusion undergoes some sort of reset as soon as it leaves the normal perimeter section and moves to the bridge section.
  • This results in the initial part of the bridge perimeter starting from almost 0 flow, causing just a fine hair to extrude
  • ...and about halfway through the bridge, the rest of the flow comes all at once, leaving a glob in the middle of the bridge

I've tried messing with speeds, acceleration, cooling (no cooling, 100%cooling), temperature, but the behavior is always the same. Maybe I am bad at describing my issue but I can't seem to find a similar post on the net so far. Normal supported perimeters print fine, but anything that requires a bridge, like the top skin, turn out pretty poorly.

Best Answer by Cullinaire:

Fixed the issue - it was mainly due to too low of extrusion multiplier which was set at 0.98. Now it's 1.02 and bridging works much better.

I've added a picture with the description of the problem but it doesn't show up in the actual post for some reason.
