prints coming out with strange holes

[randomdude583 0]

Im using a homebuild ORD Hadron printer with Cura 15.04.6 i recently updated, and ever since the prints have been coming out badly. I have absolutely no clue what happened as i hadn't changed settings before it broke. im including photos of what the prints look like.

Hi and welcome,

That looks like massive underextrusion, are you sure it's related to the slicer? Does an older gcode with your previous version do the same? It might be related to hardware

Oh Thank goodness, I thought I was the only 1 to have this problem. It has been a massive ball ache since I updated as well. Before I had no problems with PLA. Only had problems with the Formfutura Brass filled one. But now it is with all my filaments.

Not sure if you are asking me, but yes I have.

Why yes, I am!! The pic you posted has dramatic underextrusion, can you see light through the nozzle after atomic pulls?

Turns out its your filament diameter, you gotta make sure to update that value in Cura or it will fail this way. it works much better now that I changed it
