Uneven layers

I'm beginning to think this may have something to do with the fact that I'm using a Volcano hot end, could that be the case here?

The strange thing is that this happens at the same height when you compare 45° and normal orientation, so I think it is not the extruder or fillament. It also means it is not X or Y axis.

I had some similar Z wobble problems when I updated my Cartesian machine to two independent Z motors. I spent ages looking for bent rods, loose axes, but then it was pointed out that I'd made a massive noob mistake and put M584 Set drive mapping after the motor settings! This causes any axes that don't have accelerations, jerk etc set to use default values, which may work just well enough to fool you into thinking you set it right, and to look for other problems. Do check this! Feel free to post your config.g, too, to see if there's any reason your motor settings on Z may be causing this. Are all your Z motors the same?
As you're running belted Z, the only other thing to check is that none of the pulleys are running eccentrically, which would cause Z banding.

i had a problem like this. for me it was ever so slight binding of the z axis. redid the z assembly until in ran without the slightest resistance without the lead screws, then added the lead screws.

@droftarts Hi!
I just checked this and I have the M584 before the motor settings
what do you mean by "eccentrically"? -
@Veti YEs, I'm beginning to think this might be the problem here.. maybe my Z setup is to contraint.
