    For your question about not printing in the center I think you need to change this setting for your printer But the scaling part I am not sure. Does cura show the right dimensions if not it is most likely a problem with exporing the part form Fusion You could check if you are exporting in the right dimenions so: mm or inches. when you go to export (as stl) I belief there is a tab named 'settings' where you can change a lot of thing (not sure about this though)

    I think it is the Ploybox edition 2

    Have you dried the PVA? I keep the PVA in a dry box with controlled humidity and when i start to print i make sure to extrude a good bit of filament so it is nice and clean and now brown spots on the filament.

    Cura 4.2.1 I always wait a while before updating cura so there are no big bugs left in Cura mabye I will update soon to 4.3 or newer. Thanks for the response👍

    I have the same 'problem' but only if i try to select the hoops or linear axes at a point where it is close to the settings on the right side of cura. with close I mean with in 4 cm from the settings box

    Mabye there is a easyer solution😉(I always think of the hard ones first🤦‍♂️). have you tried printing with a (bigger) brim or a raft. If it still bends with these options then you could start looking into modifying the part.

    Temperature seem good, that wont be the problem. Are you using an Ultimaker and/or is your printer enclosed? I dont know where and in what kind of enviroment you are printing but mabye there is a gust/stream of wind that blows over the part and cools it down(to quickly). Mabye if you remove some surface area on the bottom in the middle it will 'warp' less there because there is less matieral that is in contact with the build plate. I have drawn a quick cross section view of your part (looking at the image i thought it looked like this🤔) In red is what I mean with less surface area:

    What kind of adhesion are you using? Mabye put a bit more down in the middle. I use 3Dlac from lay3rs and dont have any 'warping'. also what temperature are you using for what material?

    I think that this is the case. The Ultimaker S5 that I work with has the same problem at the start of all the dual color prints. It always retracts the second material but doesnt insert it back in

    Go to the settings and disable 'automatically drop models to the build plate' then you can change the Z hight of the model. (not sure if this will to the job) But why would you want to do this. why not glue it to the cilinder?

    When I watch the printer work it lays down 2 layers of core 1 and then 2 layers of core 2 but in an uneven pattern as an example: (core one is infill and core 2 is for walls) Core 2 lays down all bottom layers *switches to core 1 Core 1 lays down 1 layer of infill *switches to core 2 Core 2 lays down 2 layers of walls *switches to core 1 Core 1 lays down 2 layers of infill *switches to core 2 And it keeps going like this.

    Here is my profile. It is pretty standard no big changes. It's based up on the profile: Fine 0.1 This print is to showcase the infill pattern/percentage so it has no top layers, but it also happens with normal prints/settings UMS5 Profile dual color.3mf

    Yes the nozzles are seated correctly without any play. I will be printing dual color again today so i will take an other look. The strange thing is, is that I work with 2 Ultimaker S5 printers and both of them have this issue.
  14. NickB
    If the machine is not working as it should be you can just send it back to ultimaker right? they could take a look at it or might refund the money. If you are going to dump/explode it you can also send it to me. 😉 🤔

    here is another picture from a dual color print with those weird layers
  16. NickB
    That is weird because mine does show this setting: (ultimaker S5) Do you have the printer connected directly to Cura? (because of the 'active printer' bit) Have you tried changing the printer in cura(this may also change the active printer) just guessing 😉 When I activated this setting it was already at its lowest (0.7mm) so you can't change it to a lower value but this may be different on your machine.

    Hi guys I have this strange 'problem' when printing with 2 cores. I printed this model with 0.2 mm layer height, but when the second core starts printing it looks like 0.4mm layer height. It looks like one layer is slightly more inwards than the other layer and the second core does exactly the same but on the other layer. I'm sorry for this weird explanation but I don't know how else to say it. 😉 This happens with (1)PLA and (2)PLA but also with (1)PLA and (2)PVA Has enyone seen this before and/or has a solution for this?

    in Cura under Shell there is a setting called 'outer before inner walls' This should print the outside wall first and then inner walls. I dont know what material you are printing with, but you should look at the temperature from the water and the smoke to make sure it does not melt or deform the filament. That would not be very healty to inhale 😉 . Hope this solves your problem.

    So now that the smal part are oke I went a bit bigger but then I noticed something wierd. When there are small bits of infill it sort of curl up and does not stick very well to the previous layer. The bits of curled infill next to the wall get picked up by the nozzle and drops them later on. I lowerd the infill speed so it would have some time to stick to the previous layer. I dropped from 70 to 50 mm/s but it looks like it does not have very much of an effect. Any ideas on how to fix this?

    so I did a test with and without the Z offset and it did not make any visual difference. I did al my tests with a layer height of 0.1mm and these are the settings I got the best results with(on an Ultimaker S5): temp: 245/70 flow: 93.5 max retractions: 100 avoid parts: ON retraction speed: 35 retraction distance: 10 coasting: OFF Z offset: 0 And then I changed the layer height to 0.2mm and it came out even better. Here are some pictures of the tests: first pic is best result. second is in PLA. third is first and last result forth is first/worst test result
  21. NickB
    So I have been doing test all day and I got rid of most of it by: -Reducing the flow from 100- 92.5. -Max retractions from 25-100 -avoid parts when printing OFF I still have a tiny 'antenna' left and a couple of fine hairs but no more blobs.

    So I know stringing this is a common problem with petg but I am not sure this is stringing. it looks like there are blobs on the side walls. Some of the the begin or end of a string But on the straight is does not make sens that there should be stringing. So my question is, is this stringing or something else and how can i fix this. I have already made a temp tower (245 was optimal). I also made some stringing test where I changed the retraction distance but those came out quit good -temp: 245 retraction distance 5 7.5 & 10mm retraction speed 35mm/s

    Its unchecked. so it would be the graphics card then. Cura is running on a laptop at work so I cant really do much about the components. But thanks for the suggestion.
  24. NickB
    Alright, I thought it that the message was for the post. But I all makes sens now. Thanks👍

    When I posted the comment there was still a message in the screen saying it needs to be approved but its gone now so that is nice. I changed some setting on the tower and the problem only goes away when I disable the tower(or set size 0). I added a picture where you can see that I can see all of the layer when there is no tower. The travel is just there to change the nozzle. Do you also know why I can't change the 'color scheme' (top left of the pic) to lets say layer height so I can see what the settings on adaptive layer option does? I am on PC
