+1 Same here... I'll switch back to the previous version 4.13.1 . (that work properly for this issue)

Hi All, Cura 4.6.1 on windows 10 machine. I'm facing this strange behavior , if I multiply an object the others come printed with errors. The single part look perfect , but increasing the number multiplied generate in the print those issues, that are progressive. Despite the perspective and the deformity (I forced to un-stick the part when was still hot) I can confirm that the original part respect the geometries, and that the others multiplied parts rise that errors that became worst more are the part multiplied. (if I multiply just one part the error is slight , if I multiply 3 times the 3rd have much more shift. I tried to load the same object several time (so not multiplying it) but it didn't not help in print phase. Still this errors occur. I tried to reorient the part, still the same. Looking the slicer the parts they look always good. The only way to attenuate a lot this issue is to put all the part strait in line (all X to zero at different Y). But if they are a little parallel this issue rise. Is like there is an "x" shift for the starting part, that affect also the infill that result a little shifted too. I'm using a 0.4 nozzle and I didn't touched the width of the lines , but there are tons of options so found the culprit by attempts is an infinite work. Someone experienced something similar? sup-monoblocco-stondato.stl supporto-stondato.curaprofile

Thanks gr5 😀 I'll try also the way you suggest. On the box of the ASA they suggest to print between 235 and 255 degree. I tried very low temperature but unfortunately the layers didn't fuse for guarantee the optimum solidity of the object. I mean, i tried to break the object and I discovered that the layers where not fuse properly. Print the infill before make the thinks look a little better but give dimensional problems. So the solution don't lies there. I'll continue to investigate and I'll report what I discover...

Hi all, I am trying to go deep in using the Cura software with my Custom delta. (based on a Tevo Little monster) My Printer have a volcano hotend (original D3D) . Material ASA Appollo-X I customized more or less everything. The hardware should produce nice work. And some time it happen so good. But some time the settings are difficult to be found. So here I am. 1)On only one side , where the nozzle start to print (red square) ,the finish have no sense (for that side only). Tried temp from 220 to 260 , fan hight and low etc etc. It seems an excess of extrusion. But if I lower the flow things make even worse. After all the rest of the object is very good so...boh. On the same side but where ne nozzle don't start the level (green square) , the finish is perfect. (actually I'm trying to print the infill before ... let see what I'll get) The other side are all good. 2) When the nozzle turn happen some blob (yellow square). But this can be related to the close retraction. So I should investigate in that direction. Under the yellow square there is the support for the hole. Any suggestion where to look in the settings? Thanks for all the contributions 😉 The printer: The settings in use:

Hi, Absolutely I didnt want point far what the good gr5 say , but I would like report my experience. I had similar problems. I manage in 3 way depending on different parts. 1)as suggested , in the menu "quality" try to rise the wall width. But this can generate some trouble in the slicing. In an old post on github I found that Cura remodel all the slicing when you touch the width of the wall or of the infill. So eventually you can go in other troubles. 2)I manage to use just one wall and then concentric infill (you can't manage the overlap here) to simulate walls. Or use infill "lines" and control the overlap with walls. 3) Play with the general flaw. Tray to rise it also 15/20% for see if it can sane the situation. In general I have noticed that Cura some time have difficult to slice some 3d stl. I use FreeCAD and when the wall or the piece is not exactly a multiple of the nozzle you need to work on the settings for fit a perfect slicing. Ex. (with a 0.6 nozzle) For print a wall of 2.2cm I had to set standard wall width as 6.6 and top/bottom line width as 0.4. I know that it have no sense , but it was the only permutation that result in a good print and in a good slicing preview. Good luck!

Nothing to do for now. I switched to MatterControl for the moment. I need to do tons of experiment and attempts to figure this out and unfortunately i must make this printer work. When I'll have more time I'll return back to fight in.

Ok I definitely discovered the culprit. https://mattshub.com/2017/07/19/layer-seams/ -I tried to disable seam compensation and nothing change. (all the options present the problem). -Printing the inner part before had a bad impact on the shape so is not an option and the problem persist in any case. So..it look like there is an extra extrusion at the end and restart of the layer. In my cube this happen just in some area of the corners because the layers change for the other portions of the corners happen where are impressed the letters! So are hidden but they are still there. So is a problem of amount of material at layer change. I'm going to try the coasting option. If you have advises I'll try them all. 😀 @yellow - yep it seems that that retraction work fine but i cant test also other setting. I never tried PLA. For my purpose it didnt have the mechanical strength i need.

Thank you Smart! I have the Bondtech extruder: So I have a bunch of things to test and try !... Thank you both , I'll report about my experiments.

Hey Yellow, It seems that the "shortest" value help a lot ...see , now 3 corner are more or less fine (as the last picture) but still one corner present those strange shape (1st picture). I'll investigate all your suggestions and also will make some other test and report it !

Nothing to do with seam alignment on "random" . It seems the problem was moved elsewhere but still persist. I'm trying with "shortest" . Let's see if something change.

Hi yellowshark, You are right...sorry for the missing settings. I opened a recent post where I described some of them. Smartavionics found that problem was related to an excessive retraction. I was using a 5mm but it sucks some air and then during extrusion were generate that tiny holes on the perimeter. 2mm was enough for solve the problem. Concerning you suggestion i have already tested your settings apart the "seam" variation. I selected it supposing to reach a better result but maybe I'm wrong. This is my FIRST 3D printer so is all new. I read a lots but seems never enough. I converted a Tevo Little monster for a medium print volume. I changed almost all the electronic parts and some mechanical. https://forum.duet3d.com/topic/8397/tevo-little-monster-duetwifi-touch7-my-conversion I list my actual settings and other spec. -Material is ABS (AppolloX from Formfutura) Seems it is less prone to warping , not free from it but quite less. The temp is 210 despite the suggestion from the box. More than this the filament seems become inconsistent and pop. Like this is perfect. Is mounted on a original D3D+volcano extension. The extrusion flow is calculated on 94% for reach the right size of the wall. -im using the white glue for the adhesion on a custom borosilicate glass 110 degree. It seem to work good. Ill see further upgrade if i cant reach my goals. -The speed are all settled under the 30mm/s -Nozzle is 0.8 I give a try to to the "zeta seam alignment" and report it ! Thanks for your time!

Here again, I start to think that here, in few 3d, I'll improve so much my print quality... The new question (split , but I suppose one solution will solve all of them): -one corner of this cube is not "perfect". It look like blobby for some layers (first 2 pictures) , then "perfect" for others and than still blobby. -one other corner is regular blobby (3rd picture), less evidence or less marked as the blobby of the first corner. -the other 2 corner are "perfect". I could suspect it have to do with: "retraction extra prime amount" ? Now is settle to 0. "Z-seam alignment" ? "Sharpest corner" is now selected. "Seam corner preference" ? Now is on "Hide Seam". "retract before outer wall" is marked. Or maybe is something else? Looking at the cube have you some suggestions where to look? THANKS! Im printing at 0.5 layer height. (for a fast printing of course and i cant pretend miracles , but my hardware should good enough for a discrete result) my speed is settle on 30mm/s. OT Than...i see on the wall a wave effect that before there was not . I reduced the wall count from 2 to 1 so probably the infill disturb the wall. Ill rise again when necessary. /OT

You nailed it! In your avatar you hit the green spot ! Thanks again smartavionics 👍 I decreased from 5mm to 2mm. Ill' open a new 3d for refine other stuff. I would mark this 3D as SOLVED. Damn , I lost so much time (and materials) trying and trying , and wrote few line was so helpful and quick. 🤔

Uhhhh! Thanks smartaviocnics . Sound sensed 🧐 . I try immediately !
