That makes sense. Still strange I had to do what I had to do to allow fan settings based on material but i'm sure it's something I did some time ago which caused this to begin with. Dave

Do you by chance have some materials settings plugin?

Oddly, I get something different when I right click on fan speed. I also tried changing the fan speed from absolute to calculated by clicking the F but no change.

NM, stumbled upon the fix. Seems in each profile cfg file there was a line I had to remove from all profiles: =100.0 if cool_fan_enabled else 0.0 C:\Users\%username%\AppData\Roaming\cura\5.7\quality_changes

I'm running cura 5.7.0 and am noticing that while my temp settings follow the material, the fan temp does not. The current material profile calls for 240/80 with 60% fan. Fan always says 100% unfortunately. I am not sure what I need to enable/change for this to work but I'm sure there is something i'm missing. Any input? Thanks much, Dave

I don't recall seeing this ever before but I don't know if this is some type of layer/row interlock setting to allow the adjacent lines to bond better together? I doubt it but throwing it out there. The first layer comes out perfect despite this as you can see to the right of this. Each row does this and it appears as the get further into the row the more pronounced it gets. The first few lines don't seem to do this so with that I'm fairly sure this isn't by design. As you can probably tell the camera is petty zoomed in here so it looks worse than it actually is. It's hard to tell for sure but it doesn't seem the walls do this. The nozzle isn't clogged and the extruder isn't skipping here so I'm running out of ideas Anyone ever see this?Settings (None have changed as far as I know)Cura 5.1.0Printer: Wanhao Duplicator i3+Layer height/1st layer speed: .3/15mm/secLayer width is 100%Nozzle: 0.4mm w/ 0.4mm line widthThanks muchDave

Yeah that's exactly what I did. That definitely changed the gcode size and I can see some shading differences. Thank you for pointing this out to me! Curious how much better my prints may look due to the higher resolution. Fine: Medium:

I am not sure if this is the same thing as you have. This is under STL file options. It says "export current graphics" so that makes me feel this isn't it. What do you think? This wasn't checked so i feel it isn't it.

Interesting. I use space claim, i wonder if i can change that and if it'd benefit me any. Davae

Thanks for the reply. By low resolution do you mean the layer height? if so yeah, I'm at .030mm layer height. The way the supports are (Probably because the thinness of that channel it just supported the overhang, not the area inside of the channel. I checked this when slicing. The supports worked perfectly and also came out easily w/o blocking the channel at all. The LEDs slide right in. Of course I ran out of filament and had to change colors. This isn't anything that needs to be cosmetically perfect though.

Ok disabling the option "use towers" allowed me to print this as designed. I'm going to do some testing on this feature to see more about what it is.

No worries at all. I'm finding it is doing it on a bunch of vertical surfaces. I will try thi setting I've not changed the support X/Y distance from default and I find it very strange that there i no rhyme or reason to this. I changed orientation and it no longer supports that area but other areas now 😞 These are vertical walls, not overhangs. I tried putting in support blockers (Not that there should be support here) but it has zero effect: Here you can see these are vertical wall areas:

It's not the circle I'm trying to remove support for it. It's that errant piece BELOW the circle that supports nothing I want to remove.

Here you can see the blocker box where it needs to be: Here you can see it still shows it: And here is the location, the walls are all parallel w/ nothing greater than 60deg anywhere near here. I'm not sure if this is a bug or a PEBKAC, anyone have any input? Thanks much, Dave

Good to know. When I used gluestick I was not able to get it off completely and it lost its shine.

Hard to tell but did you lose most of your gloss from the glass bed using hairspray though?

Sorry for delay guys, this never did notify me. I did auto tune the hot end. I have played w/ temps all over the board (From 195-235) and it didn't make any difference. As a test I did move back to a .4 nozzle (Actually an entire brand new i3+ hot end I had lying around) and it still wasn't as good as I remember it used to be. I do have level glass bed (Verified w/ feeler gauge) and I actually have it tighter to the the glass than normal for first layer. Although messing w/ height and bringing it up to .100mm didn't help. I also tried to mess w/ the first layer height to see if it would change anything and it didn't. Another thing I did was tried playing w/ 125% first layer thickness just to see if it made any different but it didn't. I could try putting down glue stick or tape again but then it'll mess up the texture I'm shooting for w/ the glass bed for this item. I did modify the FW when I put in the type 11 thermistor, not sure why i said 1 before that's my mistake. I moved from a 1 to an 11. Ill try to get that file later today.

Wow tough crowd here. I had spiralize enabled for others who run into this.

Not sure what is going on but It is retracting and returning from retraction but it never actually extrudes. I have relative extrusion enabled so I can diagnose this. Looking at the gcode it seems it should be extruding. I have tried multiple printing profiles including a default .10mm layer height just to see if there was some oddity w/ my profile but no changes. Any opinions here? Attaching the gcode WDI3P_shaft_1.gcode

Using cura 5.1 and a dupilcator i3+ w/ a micro swiss all metal hot end and a hardened .6 nozzle. Have tried 3 different brands of 1.75mm PLA also. The letters are 1.9mm at the narrowest point and my line width is .6mm so it's not too short a line but short. It seems the lines are so short that they have a tendency not to look great. I am currently printing PLA at 235/60. I have a #1 thermistor and it doesn't report temp exactly perfectly according to my multimeter thermal probe (It's about 8C cooler than reported) plus the micro swiss and the thermal efficiency of the hardened nozzle are reasons I'm printing so hot. Even if I print a raft the issue is there so it doesn't seem to be bed adhesion for these short bits. I am printing first layer quite slow at 15mm/sec. Including a pic of first layer. First layer is printing at .3mm and glass bed is perfectly level (Verified w/ a .0015" feeler gauge". I have modified my Y carriage and bed to use 3 points rather than 4 also to ease w/ leveling but I've never really had issues w/ that before. Thinking it "may" be an adhesion issue for these short "blasts" of filament for the narrow spots of letters I did put down some painters tape to see but it's possible the thickness of that needed to be compensated for increasing z height so maybe I didn't give it a fair chance. I could just in case first layer z height to compensate but I don't know that's an issue. Another thing I'm noticing is the very beginning of any new line start doesn't adhere perfectly for about 1/2 a mm and sometimes it will curl up a bit. I have taken the entire hot end apart and cleaned it thoroughly to the point there was not a spec of old filament in there, it's NOT clogged Three days ago I could lay down a perfect purge line, perfect skirt, etc which made me think it was a mechanical issue but I cannot find a darn thing that could be causing this. I even had a spare extruder motor i threw in to see if made a different but it didn't. Checked esteps and they are fine as well. Since the first layer is the layer will be visible and i'm doing no post processing right off the glass bed I am trying to get this layer perfect. This is a center cap on an aftermarket wheel for my car (Lost one hitting a pothole I guess and nobody produces it anymore). Will reply w/ the one i'm printing now just for reference.

Just printed another piece i'm going to be making and a very similar issue occurred. It seems under extrusion is occurring after a retraction here. Any help would be very appreciated. I'm not sure what else to play with here. Dave

White marks are start marks. I'm no pro but this means when it's recovering from retraction it is extruding too much. if you've done all the obvious stuff and it hasn't changed perhaps look into retraction extra prime amount and retraction prime speed. Setting a negative value can help w/ that if nothing else can.

I know that's a bunch of changes at once. I don't recall ever having this w/ the other setup. Looking at the sliced object layer by layer i have determined that the issue is at the start of each line. Most of them are not obvious as the start of the layer is at an inner seam obscuring the defect but it does seem to be there. it certainly appears to be under extrusion but what do you guys think? One thing I just noticed while looking at the slice, is that the layers were these holes are the layer is starting in between them so it's like it's not priming enough at the start of each layer.. Any suggestion how to resolve this and perhaps add a bit of priming? I played w/ Retraction extra prime amount and changed it to the recommended value of nozzle size cubed (.216mm) but it changed nothing. Then for the sake of argument I set it to .500mm just to see if it'd do ANYTHING and it didn't. I also tried a .2mm layer height and it didn't change this either. I do have coasting off. I tried to let cura calculate speeds and it didn't help. In fact it also added a bunch of stringing (I'd assume due to a lower travel speed) . The outside walls are perfect but given these are at the end of the extrusion for that line I'd expect that. I'm still experimenting w/ settings but this print was all defaults w/ the exception of the following. Any insight or tips would be appreciated. Layer height: 0.4 mm Retraction: 2.0mm at 25mm/sec Speed: Inner walls: 80mm/sec Outer walls: 60mm/sec Travel: 150mm/sec Infill: 100mm/sec Relative extrusion: Off Optimize printer wall order: (True) Wall order: Outside/In Coasting: Off The speeds are the same I ran before w/ the stock hot end and 0.4 nozzle w/o issues so I don't know if perhaps the larger nozzle isn't able to move the appropriate amount of filmament after a 2mm retraction.

I'm sure i'm missing a setting here but i'm using a calibration bridge print that is part of one of the calibration extensions. The object shows 3 layers of bridging including the middle but when it prints it only prints one line on outside of print as you can see. I have not changed any default bridging settings. Occurs on any layer hegiht. Yellow shows pre slicing, red lines show what actually prints after slicing.
