I’m fairly new to 3d printing, been doing it about a month now. Everything’s has been great but now im getting these blobs or uneveness around 80% of the prints completion. I’ve printed this item.before with no issues but now its happening in the same spot every time. Im not sure if its over extrusion or under extrusion or something else completely. Other print seem to come out fine but this one print always fails 80% of the way. Any help on this would be greatly appreciated. Pictures below is example of whats happening.
It could be a couple of things.
- A cooling issue, It seemes to be different in the areas not inline with the part you are holding with your hand. I am curious about the orientation on the build plate.
- Pressure advance and/or flow rate calibration needed for your filament.
So I’ve calibrated pressure and flow rate and it all seems fine. How would I address the cooling issue?
I don’t know what filament you are using so here are some things to try:
- Adjust the part cooling fan settings.
- If possible, rotate the part on the build plates by 90 degrees to change orientation relative to the cooling fan.
- Adjust nozzle temps
- Print a little slower
How fast are you trying to print with it? Are you using Obxidian nozzle?
I updated my P1S this week and since then I have not been able to print successfully, before the latest firmware it was printing ok, now it seems very problematic.
