Do you think you could show us how to set up two stepper motors with a single nozzle I’ve been trying for three weeks and I can’t figure out the firmware or the slicing software😥PLEASE
Dear Edward,will u suggest your video for 3D printer DIY-arduino mega- ramos 1.4 - marlin1.1.8 - nema 23 - drv 8825 set up
thanks for ur prompt reply.
Hello Edward, how do you calculate the right setting for the stepper driver with a NEMA 17 stepper motor, or can you tell me how much mV must be set on the driver so that it works properly on a RAMPS 1.4 board without the stepper motors getting too hot ???? Thanks for your help and support in advance. Best regards
Christian
Sorry, I forgot to make a video on RAMPS 1.4, but this will help. czcams.com/video/m1fOqq5GYDA/video.html
There are at least two videos in the RAMPS playlist explaining how to address. Link to playlist is in video description.
Dear sir, DRV8825 become very hot eventhough I used Nema 17 stepper. I have given very small amount of current. I do not know why? Is it for marlin firmware?
It maybe related to the drv8825 tuning. There's a small potentiometer located on the drv8825, this controls current flow like a water valve. It may need to be tuned. I've not yet made a video on how to tune with test equipment as I'm still in the process of getting the test tools the demostrate, but there are several videos that exist on CZcams that may help. I'll try and find a link on CZcams in a couple of hours. The Marlin firmware is not the issue.
Dear sir, I change the values but still becoming hot.
Here is a video talking about the process of tuning ... czcams.com/video/Vp9ZRCEhVYc/video.html
Edward Sir, i hv connection as per ur instruction and all software duly install,on connecting printer in pronterface there is no action on stepper motor but the software is running ok for about few second and then error message :MINTEMP triggered.kill -printer stop .i hv not connected end stop.pls what cuold be the reason
The temperature trigger is related to the thermistor malfunction. It generally means it's not physically connected to the board.
Why does the extruder motor not work with the program used there if I am using the A 4988 drivers and a nema 23 motor?
Possible current issue with a4988. What do you see as required current on a4988 and nema23. I might tryout on live stream tonight at 6pm EST.
Hi, is it normal for the ramps 1.4 input(positive and negative) terminal to have continuity between them?
Never measured, but makes sense.
Hii can u tell me the input voltage and current require for circuit
checkout my other video in my playlist ... czcams.com/video/m1fOqq5GYDA/video.html
Would you please tell me the software that you used? I am using Windows OS. Thanks.
Ginger Wasabi I'm using Windows 10. And Arduino version 1.8.5 IDE or sketch as some call it. I'll add the link tommorow.
In the process of making my own cnc machine.
Got an MT- 170HS180A, a DRV8825, reprap 1.5 on an arduino mega.
Everything seems to work but i don't have an end stop (yet) and when i try moving the motor it makes strange clicking noises, stutters and heats up. I assume i have the voltage set wrong?
Sounds like a good assumption. In my RAMPS 1.4 or MKS Gen L playlist, there is a tutorial on how to calibrate.
@@EdwardBraiman Oops.Mine is also ramps (not reprap what). Thanks for the reply.
@@EdwardBraiman Ah. I'm dumb. My VREF was way too high. I had it at 2v and I needed 0.72v.
i have a 24 V power supply ...can i use it with the ramps board ??
Not on RAMPS 1.4, but RAMPS 1.6.
sir,i do understand ,but i need your guidance on setting of prontface that is to say setting for first print
I'll make a video,.
6:28 what is the software called? The software that you controlled step-motor. Thank.
My other tutorials may have a link.
Thank you for telling.
No problem. It's all about making knowledge easy to find so other's can solve problems for humanity.
Is the configuration made in the marlin firmware the same as axis motors ?
Yes.
I have three stepper motor same type and two stepper same type.All are nema 17 1.8 step angle. but different model.can i use them with one 3d printer.
Yes, just need to calibrate.
@@EdwardBraiman thanks
You're welcome
Hi
You're doing a really great job.
I have been following Ramps videos for a while and honestly found that your explanation is the best so far.
I consider building a CNC machine and putting a laser module on it.
I found several videos explaining the connection of the laser module on the Ramps via D9 which gives 12V.
But I did not find any detailed video explaining how to connect a laser module working on TTL 5V to a Ramps.
Of course, I want to go with laser module with TTL 5V , because I found a cheap Chinese product on Ali Express, which was satisfied with many.
Can you make a video on this topic please ?
Thanks
I would like too, but first need to order filter shielding to protect my eyes and create a ventilation chamber.
sir ,can i run just the nema 23 motor without any other devices like thermistor,end stop etc. for checkig connection,sir i hv assembled 3axis router and running it since few month.now ni want to add 3D printer head to the same 3axis router,pls advice.sir I am 75yrs young engg. this i am doing as a hoobby.pls help
You're probably going to need to modify minimum temperature, but I normally don't do routers.
do higher step counts make the printer quieter or no?
Step counts have to do with number of increment subdivisions you can achieve with the stepper motor. Tuning of the stepper driver board does decrease sound. The higher the stepper driver board does makes it possible to be quieter.
thank youu
Have the same Components But when I connectet it to Power it fried my Arduino. I have it connectet to 12V as it says that in the instructions.
My guess is something is connected differently. Can you send me a photo of the board and connected device's on Discord?
hi,
i want to ask about the output voltage from drv8825 ?
Aissou Amine I'll be doing a video on this soon. The parts didn't arrive yet to demonstrate. You will need a datasheet on your nema motors and a multimeter. I'm trying to find a safe way to demonstrate because of the power so it might be a couple of weeks.
Edward Braiman
thank you very much for fast reply,
sure i'll be waiting for ur video
all i need to understand is this
-- i have 3 stepper motors 3V 2.5A
and i have cnc shield and 3 drv8825
cnc shields works from 8V to 40V
so which power source i should use ?
9V 12A
or
3v 12A
Currently I'm avoiding giving Vref until I can explain the concept to everyone. So I'm saying I'm not yet confident to explaine, but I will be soon. Sorry, just want to give accurate information.
it will be okay i have one month to get my shoping list
I am a middle school student living in Korea. Connect SMPS to RAMPS 1.4 board and insert electricity to turn off my computer suddenly Tell me how to solve this problem.
Sounds like you shorted out the USB on your computer. Check to see if the stepper driver board is connected correctly. The en (enable) pin on the stepper driver board matches the enable pin port on the RAMPS 1.4. remember to remove all power from RAMPS 1.4 board before checking. Also could you shoot a video and post what's connected to the board so I can get a better idea of what you have connected. I need to see the connections for the stepper driver board and the Endstop to have a better idea of what you have connected.
can i use 12V *20amps* SMPS, with Ramps + A4988 + 1 stepper Motor? Please tell...
Yes.
@@EdwardBraiman But since a4988 drivers are suitable up to 2amps won't 20 amps cause excess heat ?
Thankx for replying ....
Should be okay as they draw what they need .
@@EdwardBraiman so thankx man
You're welcome.
Hello mister! Greetings and thanks before start asking...! I'm here because I'd broke one of my drivers DVR and need to buy some new... but my big question is: once I get it, can I just connect it in replacement of the broken one and then life will be better or... I need to get some especific voltage number to reach happiness? XD In that (maybe obvious) case, where shoul I place my tester? I mean, doing all on the same board where it will be installed (on the printer, indeed) - Thank you!
Watch this video ... czcams.com/video/m1fOqq5GYDA/video.html
I tried everything, even after that mention and same setup has been done, even though it's not working with drv8225 but the printer works with A4988
Check the version of the firmware. Recorded this several years ago and Marlin changed it to where you no longer need to change steps as it's different in the new version of Marlin fw.
Whenever you're in screen view your audio goes way down. More than one of your videos has this issue.
Very true. I think the issue has been corrected in my most recent videos. Checkout my SKR pro for a Endstop and tell me if it's much better. Just got a Delgado for the camera and pipe sound and camera together now.
sir ,in fact I nead ur advice on my problem in prontface error :MINTEMP
Can you post a screenshot so that I might have more context?
Edward Braiman sir can u send your Email address so that I can post u screen shot

Can you help me? I need 4 motors for my z. How can i do it?
Check configuration_adv.h and search on, "num".
@@EdwardBraiman i mean how do i connect 4 motors when you can only use 2 with drv driver? How do i wire and connect this??
There is a device that can breakout one connection into two or you can breadboard. This can be highly dangerous on this board for stepper.
Hi, When I do homing to X-axis, the motor just spins a quarter of tour, then stops. When i press the homing button, and keep it pressed, the motor keeps running until I stop holding it. Can ypu explain what I'm doing wrong?
And your videos are lit man, you helped me so much.
Thanks!!
Is it moving in the direction of the Endstop or away? What happened if you move in other direction?
is there a way I can use secondary extruder port to drive x motor as I think the driver has died
@@stiggybishope5449 Yes. Not sure if I made a RAMPS 1.4 tutorial on this yet, but this is the same process. czcams.com/video/2Hy9frwsFD4/video.html
So you press home x button, correct? Describe what happens next mechanically?
when it tries to home x the motor vibrates but does not move the currage it was working prior to it doing this but I tried an old motor as I was gonna use it to make a turn table for 3d scanning with an old motherboard
My X axis is not working.What can i do?
Which version of the Marlin firmware are you using? There is now an additional step with Marlin 1.1.9 firmware. You will need to search configuration.h for, "A4988", and remove comments or name to stepper driver type you're using.
@@EdwardBraiman I am using 1.1.9.Comments out for motor driver.But only the x axis is not working all other axis is working fine.I check the motor driver its also good.
Try switching x and y steppers boards. If problem migrates to y, then stepper was broken..
Hello there , iam working on diy 3D printer i have everithing sorted , i have been looking at people's videos having problem with them motors making noises and glitches ,but my motors act like they are dead....
PLease HELP!!!
What are the details of your machine? Which version of Marlin firmware are you using? Which motherboard and stepper driver boards are you using? Which stepper motors are you using? How long is the wire to steppers?
@@EdwardBraiman Hello there ,thank you so much for the reply, I am building CR-10 clone(a bit bigger in terms of Y axis) i am using Marlin 1.8.13 couse the newest did not complined(idk why) ,everithing seems to work fine with Ramps 1.4 /Arduino Mega 2060. I am running Nema 17 motors standart wires , i have followed many of your instructiions and everithing is just like on your side.... i had Trobleshooted it with that video as well czcams.com/video/gVoUmdE6g6o/video.html
but still they act like dead....
Search on, "A4988", in configuration.h and paste what you see for x, y and z.
@@EdwardBraiman unfortunatly i cant see nothing there is no such code in it ,and i am asuming that is an issue... i dont have any firmware for the motors ?
I was asking to check and see if there was a disabled stepper in firmware. Between Marlin 1.8 and 1.9 they made a change in firmware to enable steppers.
Sir for me X is rotating in only one direction i dont know why
What's in you configuration for hardware? Also I have a Discord channel below that has a bunch of people that can help as well.
@@EdwardBraiman ramps 1.4 with a4988 stepper driver
In Pronterface when you enter the Gcode M119 what do you see?
@@EdwardBraiman all end stopper are open
Im not getting current in x axis dir pin, which might b the problem, either program or the board??
ok so i think i found my problem. So my motors seem to be skipping steps whenever I run somethiing
Sounds like a stepper board calibration issue or the wiring on the stepper motor connector.
@@EdwardBraiman Thanks for diagnosing my issu this should be easier to fix :)
Let me know how it goes. Good luck.
@@EdwardBraiman Hey! so I need some help. Like you said earlier they might have some incorrect motor connection. I cant find a way to fix it. I tried the LED trick but I got confused. (im 12)
Does the LED light when they're side by side connected? Maybe you can ask an adult nearby to assist you. The outer two wires should light the LED when you turn the motor manually. If not then wires maybe out of order. Check the datasheet for the motor for the wire order. Should be something like black, green, blue red. Unless the motor is pre-wired when it arrived.
Please answer me .

Much slower. Granted most people in real life will tell you I speak very fast, but CC causes major issues if I speak quickly. So for the sake of less CC editing I speak slow.
