In Cura, biggest gains for the lazy: (assuming your printer is already calibrated) - increase inner wall, infill, skirt/brim and travel speed (don't increase Outer Wall speed). - remove infill if the part supports it (more walls w/o infill is faster than less walls w infill), - increase wall width to achieve same total thickness with less walls. - enable _Filter Out Tiny Gaps,_ (assuming the model is watertight) - set _Fill Gaps Between Walls_ to _Nowhere_ - turn on/off _Use Adaptive Layers_ as it sometimes saves time.

[@itzrobertho]

Agreed! Also disable infill before walls that way your infill lines won’t show through the walls when you’re printing 2 of them at 0.6mm line width.

Commissioning the VCore 3 500 with this at the moment. Thanks! 🥳

[@Hugocraft]

Great video and to add there should be something about obvious item is changing the nozzle to larger diameter to do thicker layers so less layers needed to print but sacrifice detail. I have stock .04 but now have a .06 to try out in the middle since .08 is too large for what I'm wanting

[@martinpirringer8055]

Great Video - Only thing missing IMO - especially if you go really fast - is layer adhesion. Expecially on bigger parts where the previous layer had plenty of time to cool down. The next layer needs to bond with the previous one. So If you lay down a molten noodle too fast the layer adhesion will suffer. Not critical for a "look at" model like a figurine but it can make a difference on a mechanical part. Also just checking the weight of the extruded filament IMO is not enough as at high speeds you still might get the same weight of filament but if you look at it the extruded material is shorter and thicker. This happens when the pressure inside the hotend gets too big and it compresses the molten plastic too much and then when it comes out of the nozzle it expands

[@daliasprints9798]

If you get layer adhesion problems when the previous layer has cooled all the way, your nozzle temperature likely isn't high enough or you're underextruding from going too fast. I used to think "printing on a cooled layer" was my problem for petg, and turned fan down or even off for it, but got bad surface quality and overhangs from doing so. Just cranking the nozzle temp up allowed me to print petg with full cooling (and I have some rather extreme cooling).

[@JoakimMiller67]

I am trying out SuperSlicer because you recommend it, but out of the box I am experiencing problems, especially regarding overlap, multiple types. If you really do prefer SuperSlicer, it must be ok, maybe you could do a video on how to set it up? Thanks you so much for all your brilliant videos, have learned so much! 🙏

[@szokodi72]

Köszönjük!

[@Cfontes82]

Another great video… Another Important setting for maintaining quality when printing fast seens to be Jerk, corners tend do become bulges when it’s too low, even when acceleration is correct, because the speed is not translated into corner turning velocity and we have a slight stop before starting to accelerate again

[@Mr_Pewpy_But-Whole]

linear advance / pressure advance fixes that

[@Cyb3rGlitch]

Great video! Another simple and relatively cheap flow rate upgrade is using a CHT nozzle.

[@jungofett]

What an amazing video. I have a Bondtech CHT Nozzle and it's truely amazing I now need to look at more part cooling. I have used bullseye and hero me before but I added direct drive so I had to remove the bullseye. What part cooling are people using?

[@daliasprints9798]

On a printer without some seriously upgraded cooling, your flow test piece is likely to hit cooling failures before extrusion rate limits. You can mitigate this by blowing a desk fan at the printer but then you need to make sure your hotend is sufficiently insulated or you might just strip away so much heat from the block that the flow drops.

[@TheAndyroo770]

Some good tips and I will check out your calibration website. Have you done any testing on ringing on square/straight edges prints by comparing rotating 45° on the bed so no straight edge perimeter uses just X or y axis to print but both? Also, I've been doing some experiments with prusaslicer fuzzy skin - try depth 0.06mm, length 0.1mm - it gives a cool, subtle texture and makes parts stiffer in my opinion as the internal perimeter crosses over the deviations of the outer perimeter forming a better bond. I have tested with functional parts with a 0.3mm tolerance and they did not fuse together.

[@Mwwwwwwwwe]

Chep has a crazy fast cura profile with settings cloned from ultimaker settings- requires a lot of tweaks- bit worth it

[@justinpedersen9174]

I feel like all of the different settings and dials here would lend themselves really well to an AI application. Provided you could train with all of the parameters of a printer and feed it back real world data about how well something printed you could potentially have an AI help tune all of these settings in.

[@BanditEssex]

General question, when I use the permiter speedrates you've used on your video within your teaching guide, my returns are half that for example you have 100mm/sec feeding back on the screen as 28.80mm3/sec, when I enter the same number on your website I get 9.60 mm3/sec returned in the calcuated volumetric flow?

[@squidcaps4308]

I noticed that when you start to reach the limits on your hotend, the filament it pushes out becomes thicker than the nozzle size. Increasing temperature or slowing the speed will fix that. The plastic is not coming out at same temperature and speed, some of it slows down and this allows the extruded line to become thicker. Skipping is related to the wheel grip, not just hotend. I use both now, just see when the line starts to look different and that is your maximum, at those temperature. The sensor does not measure nozzle temps but block temps, it can be seriously lower inside the nozzle at high speeds. Of course, without adjusting the pressure that the extruder gears have is a way to get faster extrusion so the free air print test still applies to the current state of the machine. But it might not be just hotend that is starting to lag behind, it can be that the extruder has too weak grip.

[@matthewweinberger7023]

Is the filament swelling not die swell from internal stresses?

[@normanziegelmeyer7693]

I learned a lot from your video, thanks. Does the ender 3 v2 have a max speed limiter to prevent any damage to steppers or other parts from extended printing at high speeds? Thanks

[@briank1131]

@teaching tech im hoping you can help. i bought an used Ender 3 of FB. It was a printer that the person was still using so i know it works. The issue i have is it looks like there are a few thing that were upgraded and not sure what all is on the printer. is there a way to find out easily. im looking at upgrading the mainboard so need to know what all needs to be done when down loading the new firmware

[@Dystrackshun]

Have you been able to get the automatic died seeing to work in Superslicer?

[@kimmotoivanen]

Visual maximum flowrate test might not be accurate - there most likely will be underextrusion before perimeter breaks (example: Bondtech CHT test model, 0.7 mm requested line width with 10ish mm3/s flow ->

[@WJCarpenter]

This is a nice video and the calibration website is very handy. There is still one thing that I am confused about. I can see that my firmware has limits on X and Y motion speeds. And I can see that the calibration site generates G-code with lines like "M220 S100 ; custom speed A - 20 mm/sec". My understanding is that M220 is sets a relative percentage. How does it know that 100% of /something/ is 20 mm/sec? What is that something, where can I find it, etc?

[@yanfik4257]

Hi Michael, I gave it a go to your acceleration tuning test, and for some reason I can't figure out, the print head stops a second or two, will still extruding causing a blob every layer on the same spot. I use Cura. Any clue please? May be your Gcode got somehow corrupted? Ta!

[@Mr_Pewpy_But-Whole]

i have been printing 95A TPU with a 1.2mm volcano nozzle at 0.6mm layer heights. i have theorized that i am encountering 3 types of flow rates. the flow rates are: The Nozzle The extruder the material. In this case i found that my nozzle and my extruder could handle the high flow rates but i suspect the material cant handle the high flow. So, by using the speeds recommended by the manufacturer i was able to determine a flow rate that is within the calculations and the prints are far superior.... althougg much slower..

[@daliasprints9798]

For decent print speeds with TPU, Overture has a "high speed TPU" product (95A) that seems to work. I can print it at about 8-8.5 mm³/s.

[@Mr_Pewpy_But-Whole]

@@daliasprints9798 interesting. i think mostTPUs max out at about 3mm^3/s

[@daliasprints9798]

@@Mr_Pewpy_But-Whole Yeah. I can do a little over that, but I have a really good extruder pushing it (Flex3drive G5 which you can see on some of my videos).

Will you be doing a Cura 5 video?

[@TheSuburban15]

For some materials, too much cooling can lead to fragile parts because of poor layer adhesion. PETG, for example, should be printed with zero or very little cooling, except when bridging

[@Jaze2022]

at 2:54 the chart shows underextrusion at around 4mm3/s. But in your test, you were able to get ~20mm3/s. I assume 1) you have an upgraded hot end, or 2) You are willing to tolerate an amount of underextrusion so long as the part holds together. This would mean dimensional accuracy and structural integrity would be sacrificed. Am I correct?
