Please help me fine-tune my prints

[iggut]

print speed ?
filament type ?
temperatures ?

To me that looks like abs printed in an unenclosed printer too fast.

If pla then also printed too fast and without a layer cooling fan.

But the bridging you've got on those is impressive.

Too many people seem to instantly leap to the conclusion that there's soemthing wrong with the printer, when most often it's simple stuff like print temps and speed that is the issue.

How big are those cubes ?

This is PLA at 205 deg
40mm/s print speed
Infill speed at 60mm/s
Wall print speed at 25mm/s

jerk settings for z and y : 8
acceleration: 800

Cube sizes:

Small Die (rounded edges): 10mm square
XYZ Calibration Cube: 20mm square
Big Hollow Die (square corners): 30mm square
