Dual extrusion with PVA supports?

Have you checked with your resellers? They are the ones that are supposed to be your main point of contact for service and warranty issues.

Both models are essentially 2D shells. There is nothing to give it thickness.

Layer shifts can also occur if the printhead hits a curled area of plastic hard enough.

You are welcome. Keep in mind, even if getting the files elsewhere, the above are things to check. 3D rendering can overcome a multitude of sins since they can work with shells and 2D surfaces. And, games are more often than not just what amounts to 2D shells without any thickness to them. Also, many, many files are just not that good when you download them.

Would that not depend on a prototype for a final process? In other words, making a separate model for the 3D printer and another for the final? I know I would hate to make two models with one being just for the 3D printer.

OK, here is the fixed file: bagon-2_EK.STL It slices fine in my UM3 printer definition as you can see here. Now, there were a few issues with the model: All parts were overlapping individual objects The main body was watertight The overlapping parts were just 'shells' This means that the other parts were 2D shells This created a lot of confusion for Cura as to where to 'cap' or 'bridge' whist trying to clean up the model. They would not union (boolean) properly in any program that is just mesh based. In the future, it would be best to make sure the parts are 'capped' so that the individual parts would operate properly. I took the easy way: I imported into a program that can work with 'voxels' and it just did the work just fine. Keep in mind that voxels and mesh are two different ways of dealing with models. Booleans in mesh is a real pain since they can create a lot of strange artifacts. However, booleans in voxels are blazingly fast and 'secure.' Voxels are volume based and when booleaned, they create a clean (superduper clean) outer volume that can then be exported into a mesh object. I could have reduced the polygons quite a bit more, but did not want to stray too far from your original model size. It really does not need so many polys since it is not really carrying much detail. How you would go about fixing this in Cinema4D, I could not say. So, I hope the above information helps in the future for you as 'capping', booleans, and 2D shells are common concepts in all modern mesh based programs.

Honestly, without knowing how it was made AND, knowing nothing about Cinema 4D, I am not sure how to advise you. I use a completely different set of programs. But, I will take a look and see if I can fix it. :)

You are welcome. 😊 I just had to do that myself, having woke up to a runout and, well, that clogs the core as it cooks that little bit just sitting there in the nozzle.

I did not see the attached model and .3mf file. So, thanks to @smartavionics for slicing it and making me look again. Sorry about that. Ever since surgery, I am not fully brain ready. But, I did download the model and it checked out fine. I had an issue with the .3mf file opening. Maybe the download was corrupted in transfer. But, I did slice the model using my standard UM printer profile and it sliced fine as you can see below. So, I am leaning towards a bad printer profile.

Would not know unless the model can be evaluated. And, if this is not for a UM printer, something may be wrong with the printer def.

Without the model to evaluate, I would hazzard a guess here, that it is a faulty model and it is trying to make 'bridges' between holes: ergo, a non-watertight model.

Actually, with everything I have read, kinda glad I was not an early adopter on this........

👍 What layer height are you slicing? could also depend on orientation of model on printbed.

🤣

Insert a box in the jaws of the model. Then use 'per model' settings to tell it to print as support. Make sure you turn off the support for the main model though or it will put support where it always does.

👍

Yeah, still not a good thing for those without the wifi to do so, yes? And, not saying why it is unavailable is kinda not helpful either.

Yeah, just clicked the link in the first post and it does not have any download options for USB. I find this to be a bit surprising as it assumes that everybody is on unlimited bandwidth. I am on a metered connection for now and this prevents me from updating my systems. So, what is the difference between downloading the software to USB or direclty to the machine? Well, To use the machine itself and wifi, increases 'chatter' between machine and whatever is connected on the other end. My basic procedure is this: If I am checking email or reading articles, I engage the wifi on the computer only. When not doing so, I disengage the wifi. How do I know that there is chatter on the wifi when not using a browser? Well, I can see the activity happen on the wifi indicator on the wifi unit. Things are always pinging out, checking for this and that. It adds up. I do not stream movies. I do not watch TV on the internet. But I still struggle to stay under 50GB per month because of all the crap that is sent back and forth. So, my question is whether I will be able to upgrade my machine operating systems via USB or not? If not, then I have to re-evaluate a few things because these machines are stuck in this time warp of non update and I do not think that is a good thing. I can still print, but have to put up with firmware that has a lot of issues. And, that limits the fun.

That is the thing. It completes all active leveling and just homes to the docking postion without any errors. Then, the screen just goes to the very top menu (Please select print from USB).

Ohhhh...my mistake. Duhhhhhhh.........

I think this is the leading STL checker online: https://service.netfabb.com/login.php I thought freecad had a better reputation than this seems to present.

Yeah, the dent is a separate issue, But the 'topographical map' look of the surrounding area is looking to be the stairstep due to the angle of the curvature. You can see it in your slice.

My S5 has been doing something weird. It goes through the active leveling on the many points (Extruder 1), then goes to a 3 point leveling (extruder 2), parks the head with the buildplate in raised posiotion, homes the printhead and then just goes right back to the main menu to 'Select a print from USB.' I am not using Cura Connect or wifi. I am doing it the old way. I am not using the beta version of firmware, but am on the latest stable release. It is very, very annoying to keep cycling the printer through this and then have to keep doing it until it decides to work. 😕
