NinjaFlex bridging (serious ninjaflex post this time)

[insta]

how

pls

It does not bridge. I need it to bridge at least an inch.

Printing 15mm/sec @ 0.5mm nozzle, 0.2mm layers, 250C, 80C steel bed with hairspray, 1.38 extrusion multiplier. I cannot find any combination of bridging multiplier and speed that causes the threads to not break off or sag straight down.

You using S3D?

Yep, but I'm not married to it.

Try increasing these:

Bridging Extrusion Multiplier: 150%
Extra inflation distance: 1.0 mm
Bridging Speed Multiplier: 150%

And lower the unsupported area threshold to 2 mm.

Might not work, but those a similar to what i experimented with in PETG, and the ninja has got to be worse than that.

Caused a buckle (plastic going too fast)

Whoops! (Maybe designing some manual support?)

Right now I'm printing bridging torture tests ... I can do 20mm "passably", but fails pretty hardcore on 30mm.

I didn't get anywhere. I'm back to thinking that Ninjaflex is hateful
