My 2 cents... Support Placement : Everywhere On the Build Plate only Only include supports that can grow from the build plate On the Model only Only include supports that grow from the model.

Are you happy with that design? I thought it looked really good in both 4.13.1 and 5.3.1. Having to support that front overhang is still an issue but with supports turned off, that model spiralizes very nicely.

I don't have the tools to check the internal structure, but I measure that gusset at .4mm thick. A Cura Minimum Line Width with a .4 nozzle is .34 so it can't go "out and back" and so won't sprialize that. This is a little test I did trying to duplicate what you have there. The gusset/web is .80 thick and it spiralized as it should.

This area is a problem. I don't know if you intended to have that "tube" there, but it is an island on the lower layers. If the gusset connecting it to the main model was 2 line widths wide it would probably spiralize. Because it is only a single line width then the toolpath goes out the gusset, extrudes the tube, and then travels back to the layer start. I've taken the liberty to delete the tube and gusset. This is in 5.3.1 and I think it looks good (but it isn't my model). GV M_Closed.stl

Cura doesn't directly support IDEX printers although I'm sure that with some workarounds it can be made to work. I don't understand though. You have two extruders and two hot ends wouldn't you just run separate materials? People here often talk about breakaway or PVA for supports on prints made with PLA, ABS, Nylon, etc. That's an obvious dual material situation.

That last model has serious problems. I think something got flipped inside-out as the lower half of the model doesn't show up in the preview, but the support does.

That's what I use but from Inventor. Models from Fusion are usually fine. The Fusion STL exporter may have user settings. You would need to search for them. If you can share the model then load it into Cura and use the "File | Save Project" command. Post the 3mf project file here.

I would guess something in the CAD model or more likely, the exported file. The "wants to fill with infill" is a clue that the model that showed up in Cura is not shelled properly.

That front overhang must be supported and since the supports are not attached to the model it is a problem because by definition the support structure is an island. This is my impression. I used 4.13.1. Travel moves are turned on. This is in 5.3.1 with no supports. GV_GOOD.3mf If that inlet area on the front is not supported then that overhang won't print correctly. It could be bridged (maybe) but it would be straight. You can't print curves over air.

This is one of those things that's more like a "missed trick" in cards than a bug. It's an omission. Since the setting "Infill Line Multiplier" get hidden when "Gradual Infill Steps" > 0 then when a user makes a change in that - it should not just hide "Infill Line Multiplier" but set it to "1" as well.

THIS POST has some background on what is going on. The problem (besides M0 not working) would appear to be that the way M25 is configured in your firmware causes it to blow through the Z moves that should return the nozzle to the working height. Not a problem when the Pause is above 15mm, but a problem when the Pause occurs at a low layer. You can try this in the PauseAtHeight settings: In the "Gcode Before Pause" box enter: M400 In the "Gcode After Pause" box enter: M117,M117,M117,M117,M117,M117,M117 The commas in the M117 line should split up the commands so they each end up on their own lines in the gcode. The M117 commands don't do anything but take up space BUT they push the Z move lines down in the gcode so they get acted on instead of stepped over. It's worth a test anyway.

Hello. I thought I'd butt in as I have a different take on this. The 5.x versions of Cura are substantially different when it come to Spiralize. Those crossing strings you see are actual extrusions as 5.x tries to complete a lap around the model in one continuous extrusion even though the part is developing "islands" on different layers. When you enable Spiralize in Cur 5.x it automatically enabled "Remove all Holes". You might want to try disabling "Remove all Holes" while leaving Spiralize turned on and see how the slice looks. If the above suggestion doesn't work then I would advise to install Cura 4.13.1 and see if it does a better job. If the models were designed for Spiralize then the earlier version might work well for you. A lot of Airplane parts show errors as they are comprised of single sided surfaces for their internal ribbing. Whether it is a boat hull or a airplane part I think you should trust that the "well known modeler" got it right for the software that was available at the time the piece was designed.

It's the correct verbiage and the correct image. The image has everything it requires except for contrast between the black font and the black background. If you zoom in really close you will just barely be able to see the words "Gantry Height" written vertically (in black) next to the vertical gray dimension line that is on the right side. You can make out "Nozzle Angle" as there is some contrast. The other things that are difficult (almost impossible) to see are "Machine Head & Fan Polygon" which is showing the X width in the top dimension line. "Nozzle Diameter" and "Outer Nozzle Diameter" are horizontal and below the print head, and "Nozzle Length" is the short dimension from the end of the nozzle to the bottom of the print head. The arrowheads indicating that the gray lines are dimension lines are pretty much invisible.

Thank you kind sir. That did it. I can rest quietly on this bench now. As for re-crossing I may require help. I had thought I was crossing Python Street when in reality it is a freakin' 16 lane boulevard and I'm wearing a blindfold. The fore-slash in the name just wasn't fair.

What I've tried and hasn't worked are variations on this: from UM.Preferences import Preferences currency_symbol = Preferences.getValue("cura/currency", "value") I often get: AttributeError: 'str' object has no attribute '_findPreference' If someone could take a moment to help an old man across the street he'd be much obliged.

Reddit has a LotMaxx community HERE. I'm sure someone has run into this before.

You didn't mention which plugin but 5axes is the author of a couple of them. His screen name here is @Cuq and he may take a look at this for you. We are into the weekend though so it may not be until Monday. In the meantime if you could recreate the exact situation in Cura (same model and same settings) and use the File | Save Project command and then post the 3mf file here he will have something to work with.

That was it. It's in that profile. This type of bug has come up a couple times recently in regards to "Remove Empty First Layers". I have written a couple of post-processors and one of them adds the Cura settings to the gcode. I used it and saw that "Infill Line Multiplier" was set to "2". Just to check I went to change it and low and behold it wasn't visible because it is never visible when "Gradual Infill Steps" > 0. So I set Gradual Infill Steps to 0, set the Infill Line Multiplier to 1, set the Gradual Infill Steps back to 10 and the problem went away. So like the "Remove Empty First Layers" bug we have a hidden setting that is being referenced and used. This is not an exact duplicate of the other reports but it is the same sort of behavior. Github bug report #14989 has been closed as the Cura team worked on that bug. @MariMakes I think this one is very similar. Should the OP fill out a bug report on GitHub?

This is an Edit. I can duplicate this. It looks like all of layer 5 is going down twice. I'd call that a bug. This is another Edit. Now I can't get it to do it again. I'm using 5.3.1 for the trial with your settings. I'll keep playing with this to see if I can repeat the problem.

I just saw this. I don't know @DivingDuck, the nozzle should not be re-extruding where it's already been. This looks like it might be a bug. I don't understand the pattern though. It's lightning infill but that outer area makes it look like concentric. @rat_tech I know some time has passed but could you load that model, re-create your Cura settings, and then use the "File |Save Project" command and post the 3mf file here? It may provide a clue as to what is going on.

I call it the "Comb" problem as in hair comb. First, try adjusting your "Minimum Line Width" down. If those fins are 0.58 wide then a Minimum Line Width of 0.29 or 0.28 should fit twice. That will force Cura to do an Out-and-Back extrusion on each fin. If Cura decides that a single extrusion will be sufficient, then that's what you will get...an extrusion out to the end, travel to the next fin, an extrusion back to the base of the fin. That travel across the ends of the fins often leaves a string connecting the ends of the fins. It doesn't do it every time, and it varies from layer to layer. If you turn on the "Starts" in the layer preview I think you will see that there are a lot on the fin ends. Ideally you don't want any. Whether it's possible or not you'll have to experiment. These are .58 wide and the minimum line width is the default .34 for a .4 nozzle. The white marks are the extrusion starts. I think the problem here is obvious. This is at .28 Minimum Line Width. There is one fin that has the normal Z seam on it. The rest are "out and back" extrusions and the nozzle doesn't stop.

You can open a gcode in Cura to preview it. You cannot alter an existing gcode file with Cura because there is no model in the file, just the machine commands.

Load the model. Set Cura up to slice. Use the "File | Save Project" command to make a 3mf file. Right click on the file and (in Windows) select "Send To... | Compressed (zipped) folder". Post the zip folder here.

I don't have a definition file for your printer so the file won't open for me as a project. I did get the model though. Both MS 3D Builder and Mesh Mixer reported errors but they must be minor. Here is the repaired model. When I sliced the model it looked fine. There were no missing layers. I mentioned a clog only because it's some thing that can happen. Until I changed hot ends and the hot end fan my Ender was notorious for clogging about 45 minutes into any print. ExportBox2_fixed.zip

That could be an error in the model or the hot end had a clog that cleared itself. Load the model, set Cura up, use the "File | Save Project" command to create a 3mf file and post the file here.
