Test cube problem

[maxehg]

hello everyone

I just got my first 3d printer and I'm having trouble printing test cubes, the top of the cube always has holes in it

#1, test cubes should always be printed 100% solid. There is no real reason to deviate from this. Most likely those were printed without enough support and the top sagged.

Print a cube at 100% infill, .2mm layer height, 60mm/s feed rate, 100mm/s travel. 235 temp for abs, 200ish for PLA.

Then snap a picture of it.
