happy holydays Edward all my respect sir :)
Thank you and Happy Holidays to you.
Great, best I have seen in a long time. This tutorial explains everything you need to know to get your BigTreeTech SKR 1.4 up and running. All tutorials should be this good. Oh, I was using all DRV8825 so I updated my configuration.h to :
#define DEFAULT_AXIS_STEPS_PER_UNIT {160, 160, 160, 160, 160 }
#define DEFAULT_MAX_FEEDRATE { 200, 200, 20, 25, 25 }
I only have one extruder and my printer is a Anet A8, TronXY X3S clone with a Prusa I3 MK2 extruder.
Thanks Richard
You're welcome.
@@EdwardBraiman : Great. got it installed and was able to compile: In this board there are five places for drivers. X,Y,Z,E0,E1 so if you have a driver in each you would increase the list to five. All with 160. but that gives an error. What else has to be changed. Thanks
I guess you just showed us as an example to set us two drivers. When i want to configurate my board completely, the jumpers for the rest of the board may have to be placed at the same position like the first two drivers, right? Im asking this because im very unsure :D Thanx for your video anyway! Ciao from Germany! :)
very good as always
Thank you.
Thank you for the video's. Would you recommend the 8825's over the 2209?
Depends on your skill level. For beginners I recommend DRV8825 and once they become novices work up to other stepper drivers. Each stepper has advantages and disadvantages based on users experience. Drv8825 is good starting place for cost and learning.
Hi, thanks for your videos. One question I have some TMC2100 drivers from my previous board and I would like to use them in my new skr 1.4. They are compatible? And what would the jumpers be like?
In my previous board (mks gen 1.4) I had to remove all the pins, is it the same in this one?
greetings and thanks.
They should, but check the manual. I've not tried them.
Thank you very much for these 1.4 videos. Would you mind doing a video on bl touch and firmware settings?
I'm waiting on a Marlin firmware fix. Already recorded half the tutorial.
Excelente video una pregunta com se configura la corriente de DVR8825 para un motor de 1 ampres?
Gracias. Este es un ejemplo de cómo ...th-cam.com/video/m1fOqq5GYDA/w-d-xo.html
Thank you very much
You're welcome.
Hi, on the SKR 1.4 manual says that when we use DRV8825 we should connect RST and SLP with jumper cap. but it seems you are not using that jumper, why?
It appeared to worked or the manual was updated after the tutorial. This happened to me with TFT display so it might be why. I'll check the manual I downloaded last year.
Hi Edward, this video is awesome. I’ve bought four A4988 drivers with skr1.4 for my ender 3. But finding it hard on how to make it work as there is no tutorial. Can you please help 🙂
You're commenting on the tutorial that explains it. What seems to be the issue?
Edward Braiman Sorry😅, i got confused as you’ve have used DRV8825 too but i just have 4 A4988 drivers.
Are you adding the translations on your videos by yourself? I'm asking because the french subtitles look like straight Google Translate copy/paste lol Ton of grammatical and orthographic mistakes, even worst sometimes, the sentences have simply no meaning lol
Your videos are really informative though so keep it up the great job and maybe let the community translates them for you in the future :)
Yes, they're Google translated. My French is terrible and my sister and mother are not interested in proof reading them.
DRV8825 vs A4988 which would you do as I am going to get a CNC and wondering which of those to grab. For 5 it is only 2-3 dollars more.
The drv8825 are one of my favorite steppers drivers. They can be tuned by ear.
Tuned by ear? Hmmmm. I did notice they can handle slightly more current and I know the A4988 very well.
Before I learned to tune by multimeter, I used the sound of the Nema17.
Can you help and create a video on the SKR V1.4 and the BL Touch and I am having trouble setting this up. I push on the BL Touch plunger and I do a M119 on pronterface and I never see a trigger on the Z Axis. And Thanks for your videos... Great Job!!! I have 2 SKR V1.3 boards up and running Thank to your helpful Videos.
Currently there is an issue with BLtouch and Marlin firmware release 2.0.x. funny thing is I've been trying to create a video for a week on this.
I understand that the error with bl touch has not been fixed yet ???
do you have a configuration for skr 1.4 and bltouch?
I think it's fun too Al now.
Hola es colocado los Drv8825 y no me funcionan es como si no le llegara voltaje hay alguna otra configuración?
Hola. ¿Qué ocurre cuando el sistema está encendido e intentas mover los steppers? escuchas un ruido? Si es así, ¿qué escuchas?
En mi caso no escucho nada con estos microcontroladores. Debo soldar RST y SLP en cada uno?
can SKR v1.4 combine XY with tmc2209 and Z Extruder with a4988?
If you're asking if you can use multiple stepper types on SKR 1.4, then the answer is yes.
I doubt its impossible to hurt yourself with 24v dc I mess with 54v dc at work never been shocked by it also damaging the board may be a strech unless you have really sweaty hands
Well I want to stress good practices to viewers. In HS we had someone in class shocked themselves and to this day we only know him by the name the teacher gave him of, "sparky". So I rather other people not get that nickname.
