Any ideas on this new issue only affecting one of my printers, only seems to be on the bottom layers of a base mode print. The layers that are not done as one continuous spiral. Photos are before and after, ignore the banding on the before! (Thats another issue I have fixed)

Can’t figure this one out, driving me mad as I have orders to fulfil

Solved:

So a combination of three changes finally got me back the correct result.

  1. Changed the nozzle for a brand new one, that helped a lot but still had a fee issues.
  2. Remeasured my extrusion amount and recalibrated the e-steps, they had gone quite a way out.
  3. Reduced the temp by 10°C apart from the first layer.

The last time I had overextrusion was due to overuse of matte filament (abrasive). The hole of the nozzle was too large. Since you only have this issue on one of your printers, have you checked the nozzle?

I will check that, I hope its that as that would be an easy fix. Also I only use matte filament.

I only know that in an other group they said it's the pressure of the Z-axis or too high temperature

[-] Prismo@lemmy.world 2 points 11 months ago

When you say pressure of the z-axis, do you know what they meant exactly? Not sure it could be temp as it’s the same, however I did change the part cooling fan in case that was faulty and the material wasn’t cooling fast enough

Could still be temperature if the thermistors on e printers read differently--that is, the same setting doesn't necessarily work out to the same physical temperature on two printers, even if they're the same model, because the thermistors vary. My suspicion would be that you're printing a little hot, and the filament is contracting after it's extruded. On the first few layers it can't shrink much because of all the material in the middle, but on the vase mode layers there's nothing preventing it.

Another possibility is that your overlap percentage between your infill and perimeters is too high. This leads to something that basically is overextrusion, but it's usually visible as more of a ripple.

A third possibility is that it's just the filament.
