not sure how good s3d would be with idex.
I never got it to do dual extrusion - but it has been a long time since I tried.

The bbd (big bastard delta) is kind of interposed throughout my original delta thread

it's all in there somewhere.
I ran across a post from 4 years ago about how bloody awful some yellow filament was to print with.
oddly I've been using it the last couple of days to make some hollow discs for clay inserts for a new designed disc sling I just invented.
And i was right - it's horrible filament alright lol
But as these discs are mainly going to be sling and never see again - I don't really care lol

The idea is the discs are held upright and actually roll out of the pouch rather than tumble every which way, which they do in a normal sling pouch.
Just had a few throws with the dogs - works really well :-)

Tell you what I'll set up a new idex printer and see what s3d does.
