Comment on Weird stringing on certain parts with Dragon HF hotend

That’s oozing. It’s unconnected to the previous section, but dripped out after the movement. The first blob attaches a little outside, the second blob on that one, building a 45 degree spire. (One crappy side effect is that for REALLY long moves, it can cause under extrusion at the restart.)

I have a Sovol SV06 Plus, also high flow. Same issue. I think it’s a weakness in all high flow because there’s FAR more filament in the melt zone. Lowering the temperature has helped a ton, but not solved it completely. I added a bigger fan on the hotend cooling section and it helped a lot, but not solved it. I’ve been told that upping my retraction to unreasonable levels should help, but I’ve not tried it. As in, I’ve got a direct drive, which usually has retraction less than 1mm, but to up it to 4mm. It’s my next experiment.

As an aside, if I could go back, I’d not get high flow option. I’d stick with the standard SV06.
