Thanks!!!! you are the best channel about 3D printing on all YT!!!!! amazing work!

[@minimal3dp]

I appreciate it.

@@minimal3dp i send you a email about strings on CR6-SE but with this video I fix it yesterday!!! Thanks!!!!

[@downsyndromebear]

Thank you for the video! Every time I saw the broken model error, I assumed it just wasn't going to work and didn't bother. Now that I know it doesn't matter, I will actually give this a try. Thanks!

[@minimal3dp]

Let me know how it goes for you.

[@NeonDreams7]

I love it! Thank you for making possibly complicated calcuations easy!

[@minimal3dp]

Glad you found it helpful. Let me know if you have questions.

[@davidham1338]

awesome!! thank you, the spread sheets are so damn awesome!!!!!!

[@minimal3dp]

Glad you found them helpful. I am constantly adding to it. Let me know if you see a formula I am missing.

[@christopherlyons7613]

Hi Mike. It's been a while, we talked back in November. Have a question on how best to do this Max Flow calculation when working with faster printers & filament. I just got a Bambu A1 Combo (love it!) to go with my FlashForge 5M Pro and am printing with some Elegoo High Speed PETG & PLA+ which can support up to 600 mm/s. Totally. understand results probably won't be great at very high speeds but would be interesting to experiment to see the speed it can maintain. Going back & forth between Orca and Bambu Studio. Definitely like Orca better and it's frustrating that Studio took out most of the Orca calibrations. So trying to my new filament (actually all my filament) calibrated in Orca and then I push those values over to my profiles in Studio. So I'm currently printing at 0.2 mm layer height with a 0.42 line width using a 0.4 Hardened Steel nozzle. So, using the formula, if Max Flow is set to 50 that should allow a max print speed of just under 600 mm/s. So when trying to run through this for faster setups, what should your min/max ranges be set for? High would obviously be 50 but not sure what to set as the low value. Appreciate any guidance. Thanks.

[@mattlydon3531]

Do you have a video on the order in which to do these calibrations? Thx

[@rohanc.8402]

Great series! Super in-depth to help even a veteran like me to learn Orcaslicer. I wanted to ask, do I have to re-run any of the other calibrations after doing the Max Flow Rate?

[@hc6979]

Still new to 3d printing so this is SUPER helpful - thank you! Would I have to run this for nozzle swaps, as well, or would they be the same because it's the same filament (using this to try to get better prints using Overture Gold Silk PLA).

[@minimal3dp]

I would not if you do a swap. If you change extruder, then yes.

[@christopherlyons7613]

Thanks for the video. I ran the test for Overture PETG with settings 5-30 with 0.5 step and the results were surprising. This is an older dried filament that I've been having some trouble using on a few objects. I'm printing on a ForceForge 5M Pro and the issues I'm seeing seem to be related to it trying to print too fast. It prints Ok and then it starts to string and it gets ooze accumulating on the nozzle and then it just fails. I've tried lowering the nozzle temp but that hasn't helped much. The odd thing is this happens only on certain models. Some things it prints fine others not. So I suspected Max Vol may be off, even though it's only set at 12 in my filament profile (which I created myself from a generic PETG profile since I couldn't find any defined profiles for this specific filament). So I guess other parameters could be off too. In general, how would you deal with something like this? I ran the Max Vol test as described here. Oddly it printed almost the entire test without issues. It was just the last few layers that began to separate unlike your test where it was a clearly defined spot where the test print quality degrraded. Granted the look of my print isn't perfect but it's mostly all together. I get a value of 29.11 mm when measuring where the quality of the print starts to degrade (I'm going a couple mm lower then where it actually degrades just to be sure). Using the equation & your spreadsheet, this gives me a value of 19.555. This is quite a bit higher than the initial value of 12, so I'm really not believing this will help my problem. What do you think? Appreciate any guidance. Thanks.

[@samuelwilli165]

Thank you for the Video and the Excel sheet. One question I have is, will this max flow rate effect my speed settings? Say, I have set speed to 500mm/s, it obvious can't be reached with a max. flow rate of 10mm³/s. Or do i have to calculate and set the max speed myself?

[@klaushg]

Recently i started using the orca slice calibration.the order i do my calibration is as followa. 1.temp 2. Flowrate.3. Pressure adv. 4. Retraction. I want to add the max volumetric speed calibration but i dont know if i should do it at the end of calibration flow or before the flowrate test.

[@minimal3dp]

I personally do it at the end. Basically the same order as the menu.

[@ericksaint3837]

This is a great video and spreadsheet, thanks! So using your spreadsheet how would I use this to push the limits? I did 5 to 30 with PLA at 210, measuring and using your spreadsheet it gave me a 26, Dragon HF hotend. But because the print was so tall it was starting to bow. Do I just uncheck the box to turn off the max I set and change the specs in orca to like 20 and 40, then adjust the start number in the spreadsheet to match, and use the measument I get?

[@minimal3dp]

I am glad you find it useful. You should be able to adjust the limits to the 20 to 40. Let me know what final number you hit.

[@wanderingcartographer2479]

Once you have volumetric flow how do you enter the speeds? I ran the flow test and got 14 for my ender. After using teaching techs speed calculator it says I should be able to print close to 200mm/s but if I got more than 60 I see bad under extrusion which to me seems like my max flow is actually closer to 5 than 14mm3/sec

[@minimal3dp]

Take a look at the extruder flow calibration test. What Hotend are you using?

[@saitavr]

Does max volumetric speed limit the nozzle movement maximum speed?

[@minimal3dp]

It will.

[@karalistecakirbeyy6650]

In that window that opened, I wrote 10 on the top and 40 on the bottom, and the bottom was 0.5, I measured it as you did with a caliper, but I couldn't calculate the flow rate, how can I calculate it?

[@Offcut55]

tried it on my Sonic setup and it would not work as it was trying to mesh over my bed size? ~Checked bed etc and it was correct?

[@subseauk]

nice video, but when I try to do the same using my Bambu Labs X1C Carbon i get all sorts of problems where I am asked to click on all the AMS reels I want to include in the test. However, when I try to select just the one reel it will not let me and the send to printer button is greyed out in Orca Slicer!! Any thoughts on the cause of this issue?? Cheers

[@minimal3dp]

Unfortunately, I don't have a Bambu so I can't help you solve this problem. Hopefully someone else here will be able to advise you. You can also take a look at the Orca Slicer github for a solution.

[@gamingwithreal1100]

the excel is locked to edit or to type in the number

[@minimal3dp]

If you go to File you should be able to make a copy.

[@barongeorg1623]

perhaps you can answer this question. a volcano .4 nozzle has a reported max flow rate of 30-40. yet when the test is run on my sidewinder X2 my flow rate is between 8.08 and 10.70. why is the highest flow rate roughly 1/3 of the capacity of the nozzle?

[@minimal3dp]

My guess is your extruder is not pushing hard enough. What speed are you printing at?

[@andrikurniawan531]

Hello sir, i have question, i do this max flow calibration for my a1, but it print normal same speed for all layer, what i do wrong? And when i check my max volumentric speed it is 200mm/s, its make me confuse

[@minimal3dp]

Recheck your calculations. It should be something on the order of 5-40mm^3

[@hansherrera6969]

great video but for me i dont have klipper my printer is a elegoo neptune 3 plus

The max volumetric flow should work if you are using either orca Slicer or prusa slicer with you printer.

[@Tome4kkkk]

It takes far too much material.

[@minimal3dp]

It does take more but I am pleased with the results. What test do you prefer?

[@nelsoncomputer]

Think of it this way, much better to spend some material getting a max flowrate that works and saves time and wasted filament on prints that don't work because you didn't run the test.
