Blob printing, offsets on the layers

[Anka 0]

Hello,

My printer did very ugly printed models. It was strange because one model was finished and the quality was good and I   start printing the bon and it looks like on the photo (low models). I checked fans and print settings and didn't find mistakes. My colleagues had and idea that maybe  is problem with new cura update (5.0.0). I chacked it. Return tu Cura 4.10.0 and prited the same  model and it was much better (the top model on picture) but still have some problem with  offsets on the layers. Did you have any ideas what should I chacked or change in printer or printing setting?

Let us know what printer you have.  The easiest thing to do is load the model into Cura, set Cura up ready to slice, and then select "File | Save Project".  That will create a 3mf file with your entire setup.  Post the 3mf file here.

Maybe you could post the "bad" Gcode file as well.  More information is better for troubleshooting.

Thank you for your response. I have Ultimaker 3. Yesterday the printer print huge model and everything was okay. I attach gcode (name: femur zdrowa) which prited ugly and the model from yeasterday which has good quality (name UM#_Zegzula forma).

It's an Ulttimaker so @gr5 may have a better understanding.

I did look at the "bad" gcode and the flow numbers look good.

Before you printed the big model that came out OK did you happen to pull out the filament?

It's not the problem with filament flow or filament as itself. In case of smaller model printer starts to make new layer slightly next to the previous one - looks like 1-2mm offset in x/y direction. Settings were the same for the bigger model as well as smaller one, filament was not removed or even touched.

With nothing to do but wait for hurricane Ian to blow my roof off I decided to try printing the femur.  It looks a lot different than your prints.

(BTW I converted the file to 1.75 filament so I could print it on my Ender.)

The support failed (and then came back to life) but the model itself came out well.

I don't know UM printers but I'm pretty good with gcode and I think in this case we can eliminate the gcode as the problem.

Thank you for that.
