Subscribed and Liked. I just did this and after one measurement it is exactly on the money. The one thing I did different was disconnect the Bowden Tube, flush-cut the filament at the fitting, run 100mm, flush-cut at fitting again, straighten cut filament, and measure with ruler on desktop. It was EXACTLY 100mm
Glad someone has put a vid on this, i would wreckomend people should do this asap when they have extruder issues. even if it is a New printer. hence there has been a lot of folks saying there extruder head is clipping their object, This option is good for beds that have Decorating tape. this option is best as if you try doing it from an alternative Datum you may get worse issues. this is because if you printer is not 100% square/aligned/True it will put you measurements off in the slicer. To calibrate along the X,Y go into controls select 100 mm and click the X+ and the Y+ button, use a pencil and mark around the extruder nozzle. you should have about a 1-2mm diameter circle you may need to remove your fan Nozzle to get better access to nozzle, NOTE it does not matter if circle is big or not totally round as we will use centering logic, Basically the middle if the circle :) . And so this is your centre. (not actual centre of bed but of our task) ok when done click the Home Button, So its out of the way. Now measure up 100mm from the center of the circle and also measure from the circle to the Right of your bed 100mm Ok breather time LOL So now you click on the 100mm and click button X+ once and same with Y+ and were back to the middle of the circle that you made drawn with pencil/marker. This time click again once more on the X+ button and see how far that goes to the next 100mm mark that you put on the bed and mark it and measure it to get measurement. and do the same calc and input into settings as Joe has shown in this vid. Just do the same for the Y axis after getting to the centre of circle, IE move Y+ 100mm from centre. (WARNING MAKE SURE YOU HAVE NO HEAT ON THE EXTRUDER OR BED) IM NOT RESPONSSIBLE FOR ANY OUCHES!
Thank you, thank you, thank you. This by far is the easiest and understanble way to get a near perfect calibration. In my case it was an origanal E step of 93 and calibrated it to 111. Almost a 20% increase. Made a world of difference on the first layer. Again thanks, keep up the great work.
Excellent video. Great job explaining how to properly use software to make your hardware function better. Many people think just plug in and go. Both software and hardware need to work together for the best prints :)
Someone may have already pointed this out, but, when you do your first length multiplier calculation (at about 7:00 into the video), the on-screen text uses the incorrect extrusion length, and, therefore, the calculated length multiplier is incorrect. What you're saying in the video is correct, thus it doesn't match the incorrect on-screen text. Despite this small error, thanks for such an easy to understand method for doing something I didn't know I should be doing. 😆
I found it easier to control by removing Bowden tube (if available) then putting filament flush with extruder. Then you can run it in and out until it is dialed in without marking filament.
you are the man im loving your channel top quality content Plus all the info and tweaks very complete without making a 3 hr vídeo out of it congrats to you keep up the good work, soon enough we will have a fan mail section in wich i would gladly participante any ways thanks for your input to the community
That's actually really helpful. I'd be a bit too scared to mess around with gcode directly, I guess. I wouldn't want to break anything by issuing the wrong command. Using Mattercontrol for that is definitely much less error-prone, I'd say! Thanks for the video, Joe!
Hi! Did you mean that the same formula is applicable to the X, Y & Z axis, isn't it? So, while the desired extrusion/moving length didn't match the actual length, you need to: (desired length / actual length) * configured steps per mm = new steps per mm value Greetings from Spain!
Hello, just got my first printer and i've been having issues where the machine wont send enough filament through, so this is a great video to follow. Problem is that when i followed ur instructions to the teeth i had some issues. So when i first extruded the 100MM it only extruded 8 MM. so for the first equation should be 100 - 8 = 92, went on with the next equation 100/8 = 12.5, the current step was set to 93 so last equation should be 12.5 x 93= 1162.5. Adding this number and trying to extrude 100MM made my filament retract and actually go out of the extruder. I dont really know why this happened hoping you could shed some light.
I'm getting this message when I click Configure for EEProm under the hardware section in MatterControl. "Oops! There was no eeprom mapping for your printer's firmware. You may need to wait a minute for your printer to finish initializing."
Hey how is going? I watch your videos just because you explain the stuff like is for someone that has no idea about the equipment and thats awesome for me. Do you sell stickers with your channel name?
Hi Joe! Thanks for the video! And thanks for the Mattercontrols tip! I didn't know it! I have the same printer as you. E94.3 by default, and extrudes around 60mm instead of 100mm. I follow the formula and I get something like E130 or so, but then nothing changes. Any suggestion? Thanks
Great video as always! Will definitely be doing this. I have a question, after saving to EPROM will SD card printing use the new values? As I dont want to keep the printer hooked up to my pc.
by mistake the overlay text was for the second calculation of the 100/102 which is why it displayed 0.97. the initial calculation was 100mm - 41mm = 59mm, and then you divide 100 / 59 = 1.6949. apologies for the confusion :)
Would this still be a current way to calibrate an extruder today? I am confident that my Anycubic i3 Mega S extruder is under extruding. Will this method work to calibrate this extruder? Thanks!
Good afternoon, my tevo tarantula pro is leaking filaments on the sides of the extruder, is too much filament being deposited? If so, how does the calibration perform? I wait and God bless.
If it's leaking around the threads of the nozzle or next to the heatbreak, probably your nozzle is not installed right. It should not butt on the heater block, but sit tightly against the heat brake. Maybe that is your problem.
Hello, thank you for making this video. I have a duplicator 4 running sailfish firmware. When I click the configure button next to EEPROM I get an error prompt saying "oops there is no eeprom mapping for your printer's firmware." Please advise? Thank you :)
Its actually not spot on for whatever reason. I also recently did a video on this because I had to adjust mine as well and the 'new' number was quite a bit off from the factory default. Not exactly sure why this was the case but it was. I used Pronterface though you can really do this directly from the machine's control panel if you want to manually extrude the filament. Otherwise its the same process / math to get your new e-step value.
I have a i3 Plus as well and I want to upgrade the stock hotend. do you have a video about the new extruder? How would you recommend it versus other options like the Flexion and Microswiss? Thanks.
to be completely honest i have only tried it out for the past week, it's been great so far but have yet to test it out with TPU and other flexible filaments. i don't see why it shouldn't work as good as a flexion if not better as it's the same concept. will have a video up in a little while once i've done more testing on it :)
thanks for the tutorial. I will be trying this with my new anycubic i3 mega straight out of the box. question: does this calibration change for different materials? or do they all extruded at same rate?
+Glen Childress if the diameter is the same, the extrusion is the same. However! Some materials might need higher extrusion rate just because of the way they are. Those little adjustment are done through the slicer though
@@3DMakerNoob Joe... ive done 30+ years in IT as a consultant and still bugger up the simplest of tasks. You are making a massive difference to newbies like me. Thanks Mate!! from UK
Update. Anycubic kossel linear plus I checked was extruding 96%.... Naughty kossel!! 😀. So I adjusted. Now it's bang on!!! You can't quantify the massive help that your channel and some of the other good contributors provide... People helping people. From all over the world every race religion even different football supporters lol😝... Thanks mate
Dude, I picked your video because I saw 2 of your other ones that were good. But this one, oh boy. There's a lot wrong here. The math is wrong, the overlays are wrong, you're using the cleaning procedure to extrude... what happened? You either should delete this video or redo it. M503 ;grab current E value from the M92 line printed out G92 E0 ;reset extruder _EVERYTIME_ G1 E100 F90 ;extrude 100mm at 90mm ; use G1 with F to use a sane speed ; unload is WAY too fast (it's meant for cleaning) and you will almost always come up short of 100mm (unless you use PLA and set your hot end blazing at like 300c). ; then plug in your old E value along with whatever you measured to get your new E value ; $New_E_Value = $Old_E_Value * ( $Want_To_Extrude / $Actually_Extruded) ; or any variation of that simple formula ie. $New_E_Value = ($Old_E_Value * $Want_to_Extrude) / $Actually_Extruded ; M92 E$New_E_Value M500 ;save ;
Hey Joe, just did this on my CR-10, and it's now dialed in, extruding exact length of filament. I'm still having issues though. Printing a 2 perimeter hollow box, with a multiplier of 1.0, the walls get way to thick, 1.12mm where they should be 0.96 (2 x 0.48). Multiplier of 0.9 the thickness is perfect, but I seem to get underextrusion on prints. So seems I have the choice of calibration being perfect but tendency of underextruding. Or going higher, where prints show less signs of underextrusion, but having the walls to thick causing some things to fuse... Any suggestions?
I am using s3d with auto 0.48. But to my knowledge, setting the width 0.40 will just lower extrusion accordingly, and put the lines that closer. So if I have the issue of 2 perimeters not being 2 x 0.48 now, will setting 0.40 not just give me the same relative error.?
+Karsten set the multiplier to 1.0 and extrusion width to manual at 0.4. If it's calibrated, it should print just right. Had the same issue on the Sigma when I changed to bongtech extruder that's why I'm suggesting it
joe i don't suppose you have meshmixer there. i so need to get back the older version. version 3. the update version has removed one the functions i use. and i can't carry on with my builds. :( i tried to find links to download the older version. :(
its ok joe i managed to sort it. someone on the anycubic facebook page sent me it. and then i got an email also from autodesk saying The auto-repair functionality has been moved to the Inspector tool (under Analysis). Hope this helps!. so will check that later. :)
Jeffrey Drake the most common way is by sending commands through repetier or pronterface. M92 codes and such. Could get tricky, this is just more straight forward
Almost all interfaces, pronterface and s3d included where you can tell it to extrude a set amount. One thing I usually prefer to do is do it without the hot end attached, so you can test retraction and extrusion at the same time.
Hmmmm…….that was something I thought about some weeks ago when I bought my E3 Pro...……...someone should design and market a filament feed rate indicator that measures the amount of filament that flows into the extruder in a minute etc. I also have to wonder why it would not be better to have an adjustable speed control for the stepper motor to adjust the filament feed rate. Then you could adjust the filament feed rate on the move according to the feed rate indicator. Over or under extrusion would be infinitely variable and corrected as needed.
+Linda Marika I think at some point we will all repeat each other in some way. We just all give it our own personal touch :) mine comes with hair ;) hehe

Honestly, you should have done this video correctly. You should have explained in actual Gcode or adjusting it on a printer. Doing it 2-3 times makes it very simple to get the process down. Your program isn't what everybody else uses and what you've done is just make it difficult. the only difference between what you did and what you would do in gcode is the extra commands you sent to save it and load it, that's really it. Although editing the firmware is still simple it is a few extra "what have I gotten myself into" steps that most people shouldn't need to get into.
+Joey duncan and an alternative process will come in due course. This is one of many way to calibrate an extruder which ultimately works. You can walk from A to B in many different ways and still get there. If it works then there is no harm, gcode can be intimidating to many beginners and there is no need for it to be. I don't want to risk giving out the wrong information before I have mastered something in the best way I know how. As you said, the only difference from what I did or "could" have done is the gcode commands. So I'll cover both and still cover everything
Joey duncan I've checked with matterhackers and they confirmed it's the same exact thing, the only difference is that the "codes" in mattercontrol are sent automatically rather than the user entering them manually. Works exactly the same way in technical terms, just a more user friendly way :)
It's changing software is all, that can be exhausting enough, you have to resetup the printer for THAT software and it may not work for their printer. In the time it takes to download and install that software alone you would be done with three simple commands: M500,M501,M503 (not in order)Or if you can do it on your printer you just have to adjust it ands remember to save which is even simpler. But I do admit it's not simple, calibration should be a focus for ALL printer software and firmware versions.
