I thought it was extrusion width. (Near) Perfect Dualstrusions with the FlashForge Creator Pro and PrusaSlicer dualstrusion-postproc.pl v1.0. PrusaSlicer is a feature-rich, frequently updated tool that contains everything you need to export … PrusaSlicer misinterpreting extrusion width percentages. Next from within your slicer check the line width is not on automatic. But why? /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. Set extrusion width → first layer to some percentage under 100% Now it slices the first layer in super thin lines and it won't work because my machine will extrude so little it won't adhere to my bed. Extrusion width of 90% for the machine with 0.4mm nozzle to be equal to 0.36mm setting. Im using the Prusa Mk3 Profile as a base, which gives me surprisingly good results. Older files did not apply overhang detection to bridges due to thin wall detection (a PrusaSlicer problem). With the support material, detachment occurs (no matter how the printing speed or extrusion width is selected) as soon as the fan cools the component with more than 80%. So there seem to be a regression bug in Slic3r PE when specifying the first layer width in percents. Edit: Most slicers set extrusion width to 110-120% of nozzle diameter, and can gap fill using widths from 50-200% of nozzle width. EDIT: New V2 temp tower files allow for proper bridging perimeters. Enter 0 and PrusaSlicer will derive the extrusion width from the nozzle diameter 1.125 × nozzle diameter will be used; Enter a percentage e.g. I use extrusion width of 0.45 mm for the same nozzle size, which gives more controllable width and better layer adhesion. You can increase the extrusion width of the first layer to make it stick better to the print bed … But PrusaSlicer is likely to be 0.42mm. But when slicing it, the width appears much smaller. Perimeter - A lower value will produce thinner extrusions which in turn will produce more accurate surfaces. Remember to reset the flow rate in the slicer to either 100% or 1.00 if the slicer uses a multiplier. As you can see in the gcode preview both models have the same extrusion width, regardless of which extruder they are using. PrusaSlicer is a feature-rich, frequently updated tool that contains everything you need to export the perfect print files for your Original Prusa 3D printer. Now from within the 3D slicer set bottom layers to 1. Step 1 Configure Settings Part 1 ... Set Minimum extrusion length to 0. 3D printer brand / version + firmware version (if known) Original i3 MK3s (not that it's important as this is a slicer issue) Behavior. So there is no way to use nozzle diameter multipliers? Isnt this overextruding on purpose? Like neophyl said, it is calculated over layer height. The main thing that changes with a different nozzle is the extrusion width. GitHub Gist: instantly share code, notes, and snippets. Extrusion Multiplier This setting allows you to control how much filament comes out of the nozzle and make small adjustments to the extrusion flow rate. Generally, you want your extrusion width to be about 110% of your nozzle diameter. Still, actual extrusion width is calculated over layer height. This additional pressure does not only squeeze You signed in with another tab or window. If you’ve never tried it, set your extrusion width for the bottom layer at 250-300%. Möglichkeit 2: Wenn ich die Extrusion Width höher einstelle, erhöht die Software die Menge an Filament, die ausgegeben wird, und erhöht so die Breite der Bahnen. When setting infill extrusion width for example, a value of 150% is used. on cura, it's set to 0.44mm by default. Successfully merging a pull request may close this issue. The external infill … The one thing I like to do is to fatten up the first layer to make it less sensitive to bed leveling errors, you can do this in “Print Settings” by increasing the first layer height to about ¾ of your nozzle size, so around 0.3mm, and also making the extrusion track wider in the “Advanced” settings under “extrusion width”, “first layer”. You’ll be amazed at the result (I … Variable Extrusion Width, say you have a wall with different thickness and you could have settings for min and max extrusion width and the slicer will automatically adjust the width for the different model widths. I am also using an older version of S3D which I don't think matters as I also use Prusaslicer with the same Extrusion Multiplier. New comments cannot be posted and votes cannot be cast. PrusaSlicer is our own in-house developed slicer software based on the open-source project Slic3r. If you’ve never tried it, set your extrusion width for the bottom layer at 250-300%. As a guideline, ABS usually prints with a multiplier of 1 (100%) and PLA prints with a multiplier of 0.9 . calibration_0.4_and_1.0_nozzle.3mf. Maybe you could try printing a test box width 0.45 mm extrusion width and measure if that still holds the measure for single wall. You specified the first layer width to be 200% of the first layer height, that should be 0.8mm. Detect bridging perimeters. 3D printer brand / version + firmware version (if known) Original i3 MK3s (not that it's important as this is a slicer issue) Behavior. Prints that don’t require a lot of strength can get away with weaker infills like Fast Honeycomb to get a faster print. Does Cura the same? But I've selected a print profile that has 0.45mm extrusion widths set. Your conflating over extrusion, or flow rate, with line/extrusion width. There is auto set which uses a mathematical formula rule of thumb to set the width or you can choose a width slightly smaller than that rule of thumb. Already on GitHub? Enables bridging flow for overhangs and turns on the fan. This will help to capture tiny details. If you change the flow rate your tool path stays the same but more material is put down. The text was updated successfully, but these errors were encountered: Did you read the tooltip ? That means it's referencing my nozzle, which is the only thing that is 0.4mm. Enter this in the extrusion multiplier field to tell the printer to only push … So if I'm going off of a layer height multiple, 1000% of 0.1mm is 1mm. So the extrusion width is thicker the better or vice versa?? ohhhhh, that makes so much more sense. After replacing the nozzle and the filament drive body on the M2, I figured I might as well throw all the balls in the air and switch to PrusaSlicer for all my slicing needs. Extrusion width validations was added. Extrusion width is how wide your line of plastic will be laid down on the plate. Im working on my PrusaSlicer profile for my Hypercube. Fixed a hard crash in a specific case when using copy-paste on objects with modifiers But in cura the line width is the distance between the lines. Hallo. The extrusion width in the tests is only the same size as the nozzle = 0.4mm. If you change the flow rate your tool path stays the same but more material is put down. Generally, it should be about 110% of the nozzle diameter. With higher extrusion widths the pressure inside of the nozzle needs to be higher as well to squeeze the material to the sides after it leaves the nozzle. Apart from some weird filament stringing, first layers sometimes (not always) not sticking to the bed and so on. Edit: Most slicers set extrusion width to 110-120% of nozzle diameter, and can gap fill using widths from 50-200% of nozzle width. For example, if your measurement is .47 take .45/.47. By clicking “Sign up for GitHub”, you agree to our terms of service and The nozzle is set at 0.4mm, so this would mean that the width is 0.6mm. Edit: Most slicers set extrusion width to 110-120% of nozzle diameter, and can gap fill using widths from 50-200% of nozzle width. I use multiple nozzle size all the time with my Makergear M2. Closing. Related issue #2829. Press question mark to learn the rest of the keyboard shortcuts. When setting infill extrusion width for example, a value of 150% is used. Ich wollte jetzt mal den Prusaslicer ausprobieren doch leider klappt das mit dem Ender 3 nicht.Hab beim Ender das Board getauscht (SKR 1.2 mini) … Expected behavior. Next, let’s analyze the contents of the form. The nozzle is set at 0.4mm, so this would mean that the width is 0.6mm. You don’t have to change the print speed, but with really big nozzles (0.8+) you might want to either – slow down to let the plastic get properly heated – or – increase the temperature a bit. to your account, Original i3 MK3s (not that it's important as this is a slicer issue). Möglichkeit 1: Wenn ich die Extrusion Width höher einstelle, denkt die Software, dass die Bahnen breiter sind und legt sie weiter auseinander. Note: This guide assumes that PrusaSlicer/Slic3r has already been successfully configured for your printer. It's still open-source and you can get it in our Drivers & Apps Package. You can create a single print profile that will work with all nozzle sizes by taking advantage of the auto settings for extrusion widths. Operating system type + version. I will use my M2 manufactures profile default for a .35 nozzle which is .4 as the example. When the line width is adjusted to 0.35mm, we can see that the printing effect is basically great, but when the thickness is 2mm and 2.25mm, the fineness of printing is not as good as the line width of 0.7mm. You get 0.2mm, which is 200% of the layer height, not the first layer height. Yes, value in the error message/sanity check is not correct, which was already reported here #4631. One of the most common causes of this problem (other than not leveling the bed tight enough to the extruder) is an improperly configured first layer setting in the slicer.To obtain good adhesion to the bed, the lines of the first layer need as much surface contact with the bed as they can get. 120% the percentage is calculated from the layer height, not nozzle diameter; Extrusion width tips. If you run the first print and you are having trouble with adhesion, add a brim. Sign in Next, let’s analyze the contents of the form. Learn the best PETG print settings (including PETG print speed) for perfect results! The reason is that creates a theoretically round extrusion that would have adhesion problems. You can create a single print profile that will work with all nozzle sizes by taking advantage of the auto settings for extrusion widths. In this second example, I told PrusaSlicer to … Windows 10 Home. If you’ve never tried it, set your extrusion width for the bottom layer at 250-300%. Your first step is to configure your PrusaSlicer profile with an extrusion multiplier of 1 and external perimeter width equal to 105% of your nozzle diameter (see pictures for reference). They’re separate parameters. Not everybody agrees with the limits but it is what it is for now. This gives us .957, which is your new extrusion multiplier! This means that: - Nozzle size = 0.4 - Extrusion width = 0.45 - Basic materials (PLA, ABS, PETG) Extrusion Multiplier = 1 I also had this problem at the beginning with other, small parts, too fast printed and cooled layers are clearly not working. Additionally make a note of the line width, for example Cura maybe 0.4mm. So the extrusion width is thicker the better or vice versa?? Not at the moment. Enabling Detect thin walls lets PrusaSlicer generate just a single perimeter that works as both inside & outside shell. Current implemenation is inherited from upstream Slic3r, it always worked that way. I'm printing at a layer height of 0.1mm. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Thanks a lot! I am doing a massive update based on the recent name change from Slic3rPE to PrusaSlicer. I think it's because it flattens it out if you have your bed leveled properly. One of the most common problems I see people having is with adhesion. Ensure Complete individual objects is unchecked. This post-processing script allows to make high-quality dual extrusion prints on the type of 3D printers that have two extruders on a single carriage, like the FlashForge Creator Pro which is based on the Replicator Dual. You didn't look at all of my pictures. Press J to jump to the feed. When setting infill extrusion width for example, a value of 150% is used. If you want your print to be strong, choose infills like Grid, Solid Honeycomb and Triangular. Operating system type + version. privacy statement. When there was an object with non-ASCII characters in the name, PrusaSlicer would suggest mangled name for the GCode when exporting. For the outermost loop of perimeters (aka external perimeters) Slic3r will default to a thin extrusion width, equal to nozzle diameter * 1.05. If you set your extrusion width greater than your nozzle size in the slicer, it’s not just extruding more material, the tool path is actually changed to reflect the wider extrusion. Flow is the extrusion multiplier. This could also reduce the amount you have gap fill. PrusaSlicer is our own in-house developed slicer software based on the open-source project Slic3r. There are some further cases where it may be beneficial to modify extrusion widths. Adaptive cubic infill was not generated correctly in case that infill extrusion width was expressed in percents. Please note that the following guide is based on default PrusaSlicer 0.4 nozzle profiles, with a layer height of 0.1mm - 0.2mm. This is considered the thinnest safe extrusion width. But when I set it to 1000%, it says that it cannot lay a width of 4mm. The default extrusion width is calculated by taking the nozzle width and multiplying it by a number I’ll call the aspect ratio, which expresses how extruded plastic is flattened onto the new layer. Selecting “0” for the width of any feature will direct PrusaSlicer to calculate a width based on the nozzle size when slicing your models. PrusaSlicer-2.2.0. To verify, I set the width to a value of 0.6mm and it made the width much thicker in the sliced part. Unfortunately this happens during the porting from Perl to C++. Please bear with me while I update everything. Selecting “0” for the width of any feature will direct PrusaSlicer to calculate a width based on the nozzle size when slicing your models. PETG combines ABS's strength with PLA's ease of printing. Have a question about this project? A thin extrusion width provides better accuracy to the object shape and minimizes the flow errors caused by … With extrusion width you have to take into account the actual thickness of the filament you are using. The nozzle is set at 0.4mm, so this would mean that the width is 0.6mm. When the line width is adjusted to 0.35mm, we can see that the printing effect is basically great, but when the thickness is 2mm and 2.25mm, the fineness of printing is not as good as the line width … Hence the message. One reason for modifying the extrusion width has already been discussed: increasing first layer extrusion width in order to improve bed adhesion (see p.). PrusaSlicer CR10 Mini Config Bundle. Just make it 0.351 to nudge it. At the same time, if I set the width to 1000%, an error shows up stating that it cannot extrude a 4mm line, so it must be calculating the width properly, but not actually applying it. So if your layer height is 0.2 then 150% is 0.3 wide. However, walls thinner than a single perimeter extrusion width will likely still be ignored. Print Settings > Output Options. Take the expected width and divide your measurement by it. Also added pictures indicating where the tuning parameters are located in PrusaSlicer. We’ll occasionally send you account related emails. After you've printed out your PrusaSlicer-2.2.0. Percentage setting is not done over nozzle width but over layer height. Planned over extrusion is a good thing. It’s one of the good features of Creawesome. It’s built from the Slic3r project, gaining features used by Prusa’s printers / filaments and a considerably improved UI, with a full-time paid staff working on it: You’ll be amazed at the result (I couldn’t believe it worked when a friend showed me). Windows 10 Home. of the extrusion width. This can be compensated for with a lot of glue spread on the bed, but w… The strength of your print will vary depending on what kind of internal infill you choose. It seems very cumbersome to have to create overlapping profiles for the same layer height with different nozzles, and then again for each material you use. For full control over that value I used PrusaSlicer 2.1 for all prints. It's still open-source and you can get it in our Drivers & Apps Package.
