Layer issues Z axis.

Ok here goes. I've been tinkering with my printer for the last few months. Managing to print some usable prints, just not the great quality.

Everything is correct, 20x20x20 cube is fine, but the layers are notifiable and are not really close together.

So, I decided to change the steps, lowering the Z axis by 1000. The layers are perfect prints come out looking great.

BUT.. now the prints are too short... piece I printed is supposed to be 10mm high, its 6.

any ideas....?

If you reduce the steps/mm you will get thinner layers and your parts will print too short, as you have discovered. That isn't a number that you play with- it is a number you calibrate then leave alone. If you're having problems with layers not sticking to each other, there is some other problem.

Are you printing ABS? Is your printer enclosed? Are you running a print cooling fan?

Before you mess with any steps you should make sure they are correct.
Changing the values from your guts to "cure" a printing problem is the wrong way.
Do the entire calibration so all steps are correct.
Than setup the slicer correctly and do another test print, from there we can proceed if still necessary.

I'll print of another part without changing the steps so you can see the difference.

Before I say I may have figure out what was wrong with the prints, remember that I've self taught!

I had the later height set to 0.5, I figured because it was a 0.5 nozzle... That was the right height. Seeing how this next print comes out.

Hmmm, that could be the obvious fault LOL
try with a layer height of 0.4mm max and it should work
