Very good info! Do you have another video for the tmc2208 driver?
Sorry. should I first install Marlin on the Arduino board or it doesn't make a difference?
Thank you for the great video, would you be able to share the size of the plastic container and maybe a link where can we purchase this type of plastic container? Thanks. A million.
Where did you get these boxes ?
On multimeter i set it to 20v dc for measuring When i rotate potentiometer the value on multi mere is 11.85 and its not changing
Thanks for explaining so simple. watching everyone else they say to adjust to rated of motor so I was assuming 3.6v (rating of my motor) but every video was showing under 1 volt. glad I kept looking to find this video so i didnt blow anything up
Greetings, but, the microstepping issue? Is the same vref for full, 1/2. 1/4, 1/8, 1/16 and 1/32 ??? Thanks in advance
Hi. Yes, same settings. Current setup is independent from microstepping setup.
Thank you! Very clear explanation
Thank you for your kind feedback 🙏
excellent!! thanks!
Thank you for your kind feedback 🙏
Short and to the point. Well done, very helpful. Thank you.
Thank you for your kind feedback 🙏
A fórmula mais adequada para Vref do drv8825 é Vref = (Imax - 30%) x ((5 x Rsense))
Sim, se considerarmos que queremos dar uma margem de segurança de 30% e se a Rsense da placa tiver um valor diferente de 0.1 ohms
nice trick attaching the lead to the screwdriver! thanks
You're welcome :) Thanks for your kind feedback 🙏
Hi I have a question, I connected the DRV8825 driver the wrong way and I do plug in the power, will that burn down my driver? because I notice that I cannot get any Vref reading after I correct that.
If you plug the power supply the wrong way it is very likely that you may have burned the driver chip😔
Your style is amazing please make more videos
Thanks for your kind feedback 🙏 Hopefully I will have some free time to do more soon :)
Thanks for good video
Thanks for this good video
Thank you for your kind feedback 🙏
My motor initially worked but slowly the rotation stopped and wouldn't turn on again, do you have a solution?
That is a weird behavior. Are you sure you connected everything properly? Can your power supply provide enough current?
Noob here... does this mean that, by setting the imax value with the potentiometer it won't matter how many amps te power supply is sending? Also... is it normal for the driver and motor to get too hot to touch longer than a couple of seconds?
By setting the maximum current, the driver will draw that for the power supply as long as the power supply has enough power to provide it. Depending on the current setting, it is normal that the motor and driver get hot. That is why in some cases it is recommended to use heatsinks and/or cooling fans
@zerotoheroengineering ah, good to know! thank you for the reply!
Great tutorial. Thanks! Sadly my A4988 jumps from 0,1V by turning 1° directly to 1,7V. No possibility to adjust 0,8V at all ...
This a very weird behavior. Maybe you got a defective unit? 🙄
explanation for idiots
We are glad that you understood
Génial super vidéo merci 🤗🤗🤗👏👏👌👌👍👍👍
Merci :) 🙏
Best video on the subject, well done !!!
Thank you for your kind feedback 🙏
Hello my friend can you help me
How can I help you?
Thank you! Best Tutorial on this.
Thank you for your kind feedback 🙏
Thanks for not trying to be a comedian while explaining the technology.Getting straight to the point and not wasting words earned you another sub. THANKS!
Thanks for the kind feedback 🙏
Thank you for the concise presentation of this important subject 👍🙂 I'm currently in the process of organising my electronics hardware and I'm using Method 1 (storage boxes) for small parts, and plastic lunch boxes for the the larger parts (switches and knobs). I'll probably use Method 2 (parts cabinet) for the electronic components, as space is limited.
so my stepper motor is 1.3A; x 8 x 0.2 (0.2 is the resistance i measured) = 2.08? Seems a bit high. hmmm.....I'm definitely taking 10% from that!
Your calculations seem correct and taking the 10% is a wise decision :)
well done... THANKS
Thank you for your kind feedback 🙏
merci beaucoup pour votre travail ,video tres bien expliquer vous avez un aboné de plus
Merci! :)
Thanks for the great video
man whre tf r u ???? please do more
So my question is, why did you select a 12v 180w power supply? I’ve been trying to find out or understand what the minimum power is required. Can I use 12v with 74W or can I also use 24v @144W? I have been unable to find out how I can possibly use higher voltage power, and how to go about it.
I used that because that is what I had around. It is the type of power supply that is also used in 3D printers. For setting the Vref you can use a very low power power supply because almost no current is drawn during the process.
oh thank you so much otherwise I burn my motor coils for too much current
Thank you for your kind feedback🙏
hello. for A4988 i see this formula : current limit = vref * 2.5 vref = current / 2.5
That formula is only true for a specific value of the sensing resistor. There are boards with different resistors as I mentioned in the video and the value of the sensing resistor must be taken into account
Clear and precise
Thank you for your kind feeback! :)
Thanks mate, precise and detailed at the same time.
Thank you for your feedback. I''m happy that it was useful to you :)
I have a problem and I don't know where else to ask, but for some reason I'm getting a 12v reading off of the potentiometer Does anyone have an idea on how to fix that?
It might be because you may have not yet connected the ramps board with the Arduino board.
@@hamzajamal5661 nah that can't be it, the first thing I did was connect the ramps and the arduino
@@ikermorell1078 try at stack overflow/exchange, you might get a solution there
@@hamzajamal5661 alright thanks I'll try
Seems like A4988s have a max of 2A per coil
Yes, it can got up to 2A per coil with proper cooling. 1A per coil is the max recommended with passive cooling
Uitstekend uitgelegd, ik heb al 2 opgeblazen. Nu heb ik al nieuwe besteld en ben op internet aan het zoeken hoe A4988 en DRV 8825 moet worden ingesteld. Maar nu begrijp ik dat met de stappen motor en de driver eerst goed moet uit gaan rekenen om de Vref in te stellen. Heel erg bedankt van deze Video uitleg.
I had to use google tranlator for this one :) I'm glad it was helpful for you. Thanks for your feedback :)
Thank your great help. Got motors to run right; finally. : = }}
I'm glad it was helpful for you :) Thanks!
Nice info, thanks :)
You're welcome! Thanks for your feedback! :)
Useful information. Well presented and explained.
Thank you very much for your kind feedback! Cheers! :)
How would I go about this if my power source doesn't have a positive and negative voltage section like yours does (just one cable for the entire power source)?
If it just has one cable coming from the power source you'll have to strip the insulation of the tip of the cable and there you will find two conductors. They can be two separate wires or one of them can be isolated and the other not. If this is the case, the one that has insulation is usually the positive and the other is the negative. However, the best to do is to test them using the multimeter.
bingoooo
I'm glad it was useful for you :)
I wish I lived where you live. The ut61e is like 140 where I live. I have the ut61e + and you're right is a great multimeter and I've had many. Thanks for the video too. I forgot how until you said crocodile clips haha
Well I actually ordered it from China. If I had bought it locally it would have been much more expensive. Regarding the "crocodile clips", some people also call them aligator clips. Thanks for the feedback :)
@@zerotoheroengineering are you insulting me? I'm horrible at sarcasm. Lol i was thanking you and probably got the word messed up lol I got mine from China too but they've went way up in price in China. I paid like 110cad. Great meter the probes are no different than any of the probemasters I have. I actually mailed a set to a youtuber in new Zealand. When I ordered them I didn't realize that they were just the probes but they retracted way too easy. I got a new set with all the different parts for Xmas and they send them in a giant case like a good ratchet set would be in but no one keeps their probes in the case. There's a set on Amazon from a company called bionzo for like 50 dollars that I already had. If not for the soft wire on the pm there's no difference in quality. I forgot how to set vref and your channel popped up. I'm only a newb man, 2 years into circuit level components and theory as a hobby. Much more fun than coding. Peace
Perfect training video! Thank you! You are the best! I've been printing for a couple years and this is totally going to save me a bunch of headaches. My driver V-refs were way too low.
Thank you for your kind feedback. I'm happy that it was useful and easy to understand :)
is it okay to use a 15amper power supply for a4988?
Hi. Yes, it is perfectly ok because the A4988 will only get the amount of current set by VRef.
Superb! wonderful demonstration, thanks!!!
Thank you for your kind feedback! :)
Best tutorial on Vref! It should be possible to do this without the ramps board, right?
Thanks for your feedback. Yes, it is definitely possible, even on a breadboard. I just decided to use the Ramps because I already had it and makes everything simpler.
Great video, very informative and explains WHY for things, rather than just DO this. Can you do one for TMC 2209 too? :-D I notice you only have 2 videos, did you stop?
Thank you so much for your feedback. Regarding the TMC2209, yes. It was already on my plans, actually :) . I didn't stop making videos. I just have been been busy with work and a few projects (some videos about them coming) but didn't have time to edit the videos yet. I didn't stop, just had to pause. Hopefully I can get continue making videos soon :)
