Great video as always, just had someone asking about this yesterday so I linked them here. Playing it safe is a good bet. I used this test last week and broke the layers apart to measure thickness. What "looked good" measured noticably thinner than the section below it, so I ended up stepping down more than just eyeballing it would have gotten me.

[@ModBotArmy]

That’s a great idea. Especially for verifying your parts won’t be weak from not enough filament being extruded. That route would definitely help you hone in on a more exact rate.

I am loving this slicer personally. Not having an x1c or p1p I hadn't really considered the Bambu studio slicer but being able to arrange my projects all in one file with multi plate support is honestly amazing. I also love using the Ellis printing guide for setting up printers and walking through everything for calibration it's been a big help klipperizing old printers or getting my new builds set up and printing great.

For big project having multiple plates set is sooo nice. I used it recently when printing the P1P enclosure and it was a great help.

I have a few remarks: 1) IMO better to use not AutoSpeed setting but Filament - Advanced - Max volumetric flow. flow can be different for the same type of filament, even the same manuf. (see CNC kitchen video for that) 2) The missing part for me with this method - I don't see how much underextrusion changes prints that are more than 1 perimeter shell. On the shell it might look fine but in reality underextrusion is there and slicer "perimeter fusion" math won't work anymore. Say Hi to separated walls. And back to #1 if it looks fine on single wall in green there is no guarantee it will work in black due to different characteristics of filament. I wouldn't be so picky about it usually but I do mass production of parts and you want to do it fast. So I fine tuned everything for semi-transparent orange PLA. And when I changed to black PLA it was underperforming and a batch had to be scrapped, slowed down and reprinted. If you near your printers capabilities every subtle difference in filament will pop up. Either test more or make like 70% of printable flowrate your max volumetric speed

[@sierraecho884]

You are doing 3D printing, if you want to do mass production create a mold instead. Unless you do one offs and only small batches which again is not mass production. You can´t really do mass production, not comparable to most other methods. Maybe it is your definition of mass production is you produce 1000 parts or so.

[@CodeMonkeX]

One thing I do not understand is that PursaSlicer and others seem to have the Max Vol Flow linked to the filament. But it's actually linked to the hot end and the extruder more than anything. So I do the test with a 0.4mm nozzle and a 0.8mm nozzle and I get very different results. It seems to be hard to save these settings in the slicer.

[@3lemental]

Because each filament flows differently. As for the different results. OrcaSlicer uses the thickest line width and layer height combination. So, different nozzle with change the flow rate as well.

[@sierraecho884]

It´s both. The hot end determines the heat output and the surface to the filament, so does the nozzle but the filament also plays a role in taking in that heat. You can heat PLA way easier since it get´s soft at around 60°C already but you will need much more temp to do the same with PETG. So it´s both parameters.

[@slothgirl2022]

Wouldn't too much filament being pushed through lead to overextrusion, not under? Refering to @0:14 or so.

[@ThomasS17]

It's not too much filament being pushed, but too much being requested by the slicer (attempted to be pushed), i.e. more filament than the hotend (or extruder) can handle (edit: a reason can be that the hotend just can't melt the plastic fast enough). So if the slicer moves at a fast speed (or thick layer height) and thinks 20 mm3/s are being extruded, but the hotend can only do 14 mm3/s as in this case with the Revo, you will have underextrusion (basically missing plastic worth 6 mm3/s).

Im 8 months late to the party but well here i am with my black week buy called neptune 4. Just by logical thinking i came to what you are describing in the video. But with that there is a new topic on my plate now. Well seems like for not all but for many typical prints 0.2 layers are fastest now with capped flowrate. I tried everything i could to get 0.28 layer heights to spit out faster prints but its impossible since you will exceed that 0.4 nozzle quite quickly. So the next question is how to savely overheat filament. PLA often goes to 220°c(per manufacturers advice). I could go greatly above it if i push it through fast enough. But how fast do i need to push it through so that the filament doesnt burn itself down in the nozzle? In the end the filament would still only go through with 220° but the nozzle has idk 250° or sth. Is there any good way to push the nozzle temps without trial and error? How do i make sure that speeds/flow are maintained so that the filament doesn't overheat in the nozzle?

[@Finsternis..]

Isn't that flow rate highly dependend on filament and temperature? Surely my ABS filament flows slower than my PLA filament, and surely the ABS filament flows easier at 230° than at 210°?

[@petercallison5765]

Of course, you need to run a test for each type of filament. You then need to deal with the changes to due to temperature and the effect of different nozzles.

You just have to click on the color swatch for the filament. So on the left side above the slicer settings there will be between 1-4 filaments listed (depending on your printer and if you are using an AMS). Click or double click on any of the small color squares and you can set any color :)

[@frankdearr2772]

great ,, thanks 👍

[@lauretiu]

i know this is a silly question but if i set the "step" value to 1mm form 0.5 how much is that in mm3? 2mm3? so i multiply by 2 the number of lines plus the default value i set of starting point ?

[@richard3365]

No calculations required, it does all the work for you. "Step" is how much the amount changes each time there's a line. So, as an example, if you have it set to start at 8, with a step of 1, and you notice degradation after the 5th line (5 increases of 1), your degradation is at 13 mm³ so you'll want to set it to 12 mm³ in your slicer. If you start at 8, and have a step of 0.5, then the 10th line would be the same 13 mm³. But if you notice it looks great between line 9 and 10, then you can set it to 12.5 mm³ instead of 12. Another way to look at it: the space before the first line is the same number you set as the start. Each space after that goes up by your "step" setting. Counting the spaces between the lines, count by whatever your step is set to, only counting the "good" faces. With a step of 1, you would count 8, 9, 10, 11, 12. If your step is 0.5 you would count 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12. Whatever number you stop counting on, that's the number you input into the Max Volumetric Speed setting. No need for a calculator, just count them.

[@NSCXP2005]

Great video Modbot. What flow ranges should I do for a Pheatus Dragon High Flow hotend? Thanks.

[@richard3365]

They say online that the rate is supposed to be ~35 to 38. So you'll want your end to be higher than that. The rest is really up to you. Start with whatever you're comfortable with. Just keep in mind that at some point the single-thickness wall is going to become unstable and you'll start getting artifacts just from its weight and the action of the new filament getting placed, so you might want to do it in segments. For example, start at 18 and go to 26. If it's still pretty much perfect, then do 26 to 34. Then 34 to 40.

Great video! Does the Max Flow rate calibration have to be done for every filament I use or is it more for the machine's hot end?

[@richard3365]

From what I've seen so far, I would say the number is indeed related to the filament (and in Orca Slicer, the setting is found under filament, not under machine), but I don't imagine that two different rolls of the same material (for example, PLA black and PLA white) will have a huge difference. You can probably get away with just doing it per TYPE of filament (1 setting for all PLA, a different setting for all PETG, etc).

[@sierraecho884]

At least for filament type. PLA is different from PETG for example. The max. flow of PLA can be almost double to PETG. You might have to tune it with different PLA filaments as well, but the difference should not be too hight. If your max flow rate is e.g. 30mm³/s for PLA I would choose 28 or 26 and call it a day.

I hope that they do implement it. That being said finding you max flow rate is still valuable. Cura will let you check volumetric flow in your sliced file on the preview page so you can use it to verify you are not trying to output more than your hotend is capable of.

[@slomo4056]

Do one has to perform the temperature tower calibration before or after the maximum volumetric speed test?

[@sierraecho884]

Before. The volumentric speed depends on the temp. The higher the tempo the higher the flow. So I would argue you should find the ideal temp before and then do the volumetric calibration, maybe somebody else has a different opinion, I would like to hear it.

[@slomo4056]

@@sierraecho884 thanks, that makes sense. And regarding Flow and PA Calibration, First Flow or First pa Calibration?

[@sierraecho884]

@@slomo4056 They all depend on temp too. The hotter the filament the lower the viscosity, so a more "runny" filament. Usually you don´t need to adjust your flow much, mine is always at 100%. As long as the extruder system is tuned properly it should be fine. You can fine tune that later maybe if you see some parts being underexztruded (this is most common because people calibrate wrong in 90% of all cases with the single wall method or some other nonsense). PA calibration I would do last because now you have your temp, your flow, your speeds all set and want to see what´s the "advanced" pressure changes do I need for the given speed, pressure, temp, material. Just don´t create a master thesis out of this, it does not have to be complicated to function well, heck I would argume most complicated stuff does not function well because you keen introducing more stuff that can go wrong. I would start with a temp tower, it prints rather slow and show how the filament behaves during x temp. You will see what your overhangs look like, if the filament droops and how well the layer bond is. For most filaments the band is rather large. For example I print my PLA at 220°C can I print it at 230°C ? Sure but cooling is more difficult and overhamngs droop al little more. Can I print it at 210°C ? Yeah I can but the layer bond gets weaker. You will have tolerances in the system anyways, so while the printer runs your temps will change between 215-225. That´s totally fine. You can then test for Extrusion multiplier so see how much flow you need. usually ±1%, so 99%-101% ca. Then you can test for retraction (you don´t need to do this for every filament, this highly depends on the hardness of material, TPU is soft and will deform more than PLA which is very hard and brittle. Mine works in about 0,5mm so I have my value set a 1mm and call it day. Max. Flow rate is important, one of the most important tests probably. If you find out your PLA looks okay at say 22mm³/s set it so 20mm³/s and you are fine. always leave a little bit of headroom for tolerances. And then jst print some parts and see how they turn out, you then adjust on a per part basis. If you print accurate parts where holes need to be aligned etc, so not only figurines you should also calibrate for XY hole compensation XY contour compensation and material shrinkage.

[@slomo4056]

@@sierraecho884 thanks for your great explanation! It is very helpful

[@sierraecho884]

@@slomo4056 You are welcome. The most common mistake beginners do when tuning their printer is they tune it to the absolute limit without leaving an headroom for any kind of problems or tolerances AND people tune extrusion multiplier wrong because they confuse two parameters. Dimensional accuracy and extrusion multiplier. They print a cube and measure the dimensions of the layer width and the overall dimensions then they REDUCE the extruded amount because of course the cube is slighly larger, it is physically impossible to print 0.4mm lines with a 0.4mm nozzle. so now they tune in 90% flow test again do 95% and usually leave it somewhere there, which means yeah your cube looks nice (has weak layer bonds but who tests for that right ?) But everything else they prent come out underextruded. So what you do instead is print small flat objects 5-6mm high with 95% infill and see how the top layer comes out. Do you see gaps (under extruson) or ridges (over extrusion). Forget about geimetrical accuracy for now. Once you have dialed that in and your top surface is smooth and everything is withot gaps ONLY THEN you tune for accuracy. Simply print small objects about 5mm, so like a 5mm staurcase and measure the blocks also print holes and measure, then compensate for it in XY compensation that´s what it is there for. And now you will get precision infill precision sized small, very small objects. Fo parts which are say 200mm long you need to factor in material shrinkage. It can be very small for PLA about 0,3% (which translates fo a failure of 0,6mm on a 200mm parts) or bigger for PETG, ASA etc. PA can be really bad with 1,5% which means if you porint some fixture with holes, your hole position will be off by 2mm or so. Never confuse extrusion multiplier with geometrical accuracy. Your laver are usually 20% or up to 200% thicker than your nozzle size, they have to otherwise there would be no Squaish and therefore not Z layer adhesion, it is physically impossible to print 0.4mm wide lines with a 0.4mm nozzle. Personally my course draft layer witdh with my 0.4mm nozzle is 0.8mm. So I can print single wall object which are very stong with only 1 perimeter of 0.8mm instead of 2 perimeters (double the travel movements) with 0.42mm line width.

[@JesseDahirKanehl]

Is the formulas that each slicer uses to determine volumetric flow the same? if they were different it would make it hard to switch. not a big deal if you only use one, but sometimes there are features that one has that another doesn't and vice versa

[@abeardedbucket]

In theory they should be the same as known values should be consistent, ie filament diameter, nozzle diameter, line width, and layer height. If extrusion multiplier is tuned in and consistent then the maximum speed at which all of those remain the same can be found. Bambu Studio, OrcaSlicer(formally known as SoftFever), SuperSlicer, and PrusaSlicer are all based on the same thing so there will probably be very little difference between them. Cura is the big outlier here, lets face it very few are going to pay for the subpar Simplify3D, at this time does not natively support setting max volumetric flow to automatically limit print speed. There is also the issue of most of the popular off the shelf printers are limited more in other ways and wont hit max flow on a 0.4mm nozzle with 0.2mm layer height. Start upping nozzle size and layer height and they may in fact get close to it. Ultimately if your slicer of choice does not use max flow to limit speed then you will just need to set those limits manually after some testing. The faster we print the more the little things matter to making a good looking and functional item.

[@JesseDahirKanehl]

@@abeardedbucket yeah I started to run into under extrusion with .8mm nozzle and big layers

[@ModBotArmy]

Yeah Revo is not a high flow hotend at all. Other than the abrasive nozzles not being available that is it’s biggest draw back. I am hoping a high flow heater core is released but if you are wanting high flow right now Revo is not the answer.

[@kilianlindlbauer8277]

Depends a ton on filament. For example natural filament gets you around 15% more flow compared to colored one. Or formfutura volcano pla flows 50% better than regular formfutura pla. Also you shouldn't forget the revos construction. The nozzle itself is on pressed onto the heater with a spring and the thermistor position is different from the stock mk8 heater block. I would be curious how much of a temperature difference this will have. I would go that far to say 220 on a revo is around 200-205 on a v6/mk8. You might want to look at the rapido. I really like them, the only reason im not buying one for my v0 is that the hotend would overwhelm the psu. They come with a copper and a steel nozzle, so thats already 40 dollars in nozzles in the package. Of course a volcano gets you more flow per money spent, but i went against the volcano on my sapphire as i would loose build volume and the sp3 isn't exactly large

Step 1: tediously calibrate flow rate Step 2: ignore that and print as fast as possible 😅 Usually step 1 goes wrong, so the rest is irrelevant. Keeping flow rate in flat zone (100..99%) creates better prints than opting to "no-fail" zone where under extrusion is significant.

[@ModBotArmy]

The calibration tools available make 1 much easier now. I have had really good results with finding that cap and setting it as a failsafe in the slicer :)

@@ModBotArmySadly temperature is missing as a parameter. I suppose you already dialed in your temp for that specific filament before.

[@blaskotron]

You'd have to increase temperature as the flow increases. So you potentially didn't hit the max unless that is tested as well.

[@ModBotArmy]

To an extent this is true. However, printing hotter also means you need additional cooling to compensate. Also, at a certain point pumping heat into these materials can cause other problems. When testing flow rate I don’t like to go higher than a range of 20c. I wouldn’t go above 230 for PLA.

[@blaskotron]

@@ModBotArmy my Bambu needs about 235 on turbo for pla. Default is 220 for generic. Going to try this test out tomorrow though. The material may not actually be reaching nozzle temperature as it's coming out so fast.

[@ModBotArmy]

@@blaskotron their profiles are tuned. That aux fan is how they get away with cooling quick enough.

[@blaskotron]

@@ModBotArmy Did the tests. At 220 C I got 25mm, 230 27mm, 240 28mm - all without changing cooling. It could flow faster but I believe that's where the quality would start to drop due to insufficient cooling. It seems the sagging corners represent insufficient cooling and gaps represent insufficient flow/nozzle temp. These are all MUCH faster than the stock profile of 12 mm for generic pla.

ZeroG Mercury One? Yay or nah?

[@ModBotArmy]

2 thumbs up from me. I did the Mercury 1.1 and Hydra. Hydra adds a lot of cost too it as you at that point are only keeping frame and psu. I would start with the 1.1 conversion and see if you feel you want to upgrade the bed. Ender 5+ being supported on both sides is a much better start than the cantilever bed of the 5/5 pro. Will have a full video.

[@Tcromb]

@@ModBotArmy thanks for the reply and the heads up on the Hydra aspect. The printer looks great! Looking forward to the video and starting the project for myself.

[@noodl3d]

10 months later and Cura still doesn't have a Max Volumetric flow rate setting... Unbelievable

[@bonjipoo]

Now called OrcaSlicer rather than softFever.

[@ModBotArmy]

Yeah they just changed it 😂. Pretty funny timing. Will be nice for it to have a bit more of its own identity.

[@bonjipoo]

@@ModBotArmy Ha. Yeah typical.

[@kilogee700]

If you find setting up orca slicer too daunting then teaching tech has a web app that kind of does the same thing. Just an idea.

[@Tome4kkkk]

This looping test wastes far too much filament!

[@ModBotArmy]

It’s single wall so it’s not as much as you think. You can also run a narrower range so it can be much smaller.

[@jnygaarddk]

I’m shocked you didn’t even mention material type. Almost have more impact than the hotend it self. PET-G only half of PLA. That’s why most slicer (also) keeps this in the filament setting

[@Enjoymentboy]

To make this process a lot more fun do the prints with dark brown filament and then once all the blond have been weighed simply discard them into a chocolate chip bag and leave it in the cupboard. It might take a little bit of time but when you hear the very distinctive crunch you'll know the joke is working

[@jackykoning]

Cura devs have decided not to implement this feature. Bad move IMO.

[@raiden72]

Both cura and ultimaker have fallen off the face of the map. Ultimaker used to have a great AMS But it couldn't change filaments in between Prints.

Thanks!

[@ModBotArmy]

Thank you for the support 🙌
