De los mejores videos que he visto al respecto, con los cálculos paso a paso, con ejemplos y vocalizando, que de inglés voy justo pero lo he entendido todo! gracias!
I don't understand the formula to figure out the new rotation distance. It doesn't make sense to me. If we get "x" amount with "y" rotation then to get "z" amount which rotation "r" we need. That would be "z" times "y" divided by "x". Right?
Nevermind. I got it. The formula is correct. Basically if we are extruding less than what we need with x rotation distance we need to reduce that number so the system knows the axis is moving less per each rotation and then to get to a certain movement on the axis the motor needs to rotate more.
wow. I am really confused by my printer. Everytime I performed this calibration, my extrusion distance got SHORTER. I started at rotation_distance of 33, and it extruded 47mm. So I increased it to 35.1. My extrusion went down to 46. This was really weird. So I changed the rotation to 27, and I got an extrusion length of 59! uhm... what? I'm using an Ender 3 V2 with bowden tube... so maybe this has something to do with it. It's VERY strange.
The extrusion distance is an indicator of how much filament you push through per turn of the extruder motor, so a higher extrusion distance means less filament going through.
@@soljoa That's so counter-intuitive. A longer distance SHOULD (to my mind) mean more filament. Higher number (more distance)... more filament. I'm not saying I think you're wrong... I'm just saying that doesn't make sense to my paltry brain. :)
@@crooker2 I found it. From the configuration reference: "The rotation_distance is the amount of distance that the axis moves with one full revolution of the stepper motor." It was so clear to me yesterday, then I lost it, and now I see it again.😅 The higher the number, the less of a full revolution it will make to extrude X mm of filament.
my distance keeps coming out negative.. plz help. so, i mark my filament at 70mm, and it goes all the way to 120mm, so when i do 70 - 120, its negative, therefore making the rest of the result negative.. why?? someone help plz
Hi there...when I originally measured I put a mark at 70mm. I then set the g code command to extrude 50mm. I then measured 23mm to the mark that I originally made on the filament...that means that I under extruded by 3mm...so I've extruded 47mm instead of 50mm (70-23=47)...If I measured 20mm from the extruder to the mark I made that would mean I extruded exactly 50mm...The reason you put the mark on the filament at the 70mm point on the filament is to take into account over extrusion. If you put the mark at exactly 50mm and your printer is over extruding you won't be able to get a measurement.
make sure u do ur math right 🤦♂i did it wrong and took me 5 first layer test 1nd 7 flow cubes wondering why its so high and nothing made sence lol figured it out now lmao 7.91 (right number)is a big change from 3.87 (wrong number)
Finally someone who shows the complete calculation for the extrusion multiplier.
spent weeks trying to decipher overly complicated calibration guides getting nowhere and you just solved it for me in less than 10 minutes. Legend.
First video that explained why I couldn't find steps setting! Rotation distance would not even been on my radar.
Now my printer is set up awesome!
Really clear explanations, thanks!
Very well explained guide. Thank you very much.

Amazing, accurate and to the point. Thank you sir!
Thank you very much for making the video, it's a big help because I encountered this problem. 🙂👍
good video contect and clear explanation. Thank you very much.
Excellent instruction! You helped me get my Flsun V400 turned right in! Thank you!
very very clear explanations, thank you :) 👍
Best flow calibration tutorial I've found so far👍 thank you
Very helpful! Thank you!
Good Video, do i have to repeat this with different filament?
Thanks a lot!
love the video

you can set retract speed in the web interface to 1 or 2
and retract 50mm
why it should be fast ?
you don't need to use console at all

Same was happening tonmr would get worse

@@crooker2 Yeah. I'm confused as well. To the lab!

Reverse stepper
So you had 23mm left un-extruded from your requested 50mm that would mean you only extruded 37, But your saying 47 am I missing something?

i keep getting diferent results, to short by 70 ish, to long by 70 ish and repeat lol
