Wow! I'm just an old guy...and I am SO impressed with your knowledge...you go girl!! I have an old robot with opposing stepper motors on the main arm axis and you just explained a possible solution. Your neurons reached my old brain !! In the 1980's I worked for Cincinnati Milacron costing robot systems on old computers using punched cards....but the youth of today are inspiring with the flow of knowledge collectively sharing skills and ideas. Even in the mid '80's we had ganrtry robots with flat tape filaments that built up 3D parts layer by layer. Milacron called them "tape laying machines" insted of 3D printers...but the concept was the same. Toray uses Cincinnati Milacron gantry systems using this process to make parts for Boeing aircraft. (Look at an old ScoreBot ER4U robot and you can see what I mean)

Just a heads up everyone - you do NOT attach 2 stepper motors to one controller. You attach the 2 motors to 2 different motor controllers, then attach the motor controllers to the SAME connection from the motor controller to the mainboard/Arduino etc. Firstly, the amps are too high, you will have x2 3amp motors attached to a control board with a maximum 5 amp available. Secondly, the motors will go out of sync, as the motor controller does not know there are 2 motors attached it, and one motor is likely to "hog" more power than the other. The a+ -> b+, etc, that is fine, do that, but on a separate motor controller, not the same one! I still gave it a thumbs up, because it was of some assistance, BUT it is not the best advice!

[@BlackOakCraftsman]

So basically just connect steppers to two separate drivers ( to avoid burning them ) but merge both driver connections to the same inputs on the arduino. Did I understand that correctly? Side note. If I use two steppers and two drivers without reversing direction on one stepper. And merge the driver connections together too the arduino input. Would that work? Thanks!

[@m3chanist]

This is wrong, it is common practice to wire steppers both in parallel to a single driver as shown here or in series, the controller is a current limiter.

[@sojosue]

Thank you very much, your video saved me

[@Mole-Skin]

This is an old thread but it came up as I am researching Synchronousity between two similar Stepper/servo motors. I too needed 2 motors facing each other and rotating at the same speed.. I have come to the conclusion it is not possible even with encoders and it's because motors may be wound slightly differently and differences in electronic components in Circuit boards.. It may only be a couple of steps per thousand but it adds up. I am talking about hobby end stuff here.. I am sure expensive gear would be proportionaly better. In my case I can fit a mechanical drive shaft to link the ends together and the benefit will be I only need one motor.. A lesson I learned early in my career was that people may not be honest with you and may indeed not want you to know their hard won knowledge.. You have to pay for your knowledge.. one way or another..

@glyn hodges Hi Glyn - I need to put to Nema 17 60 oz motors on one drive and have the spin in opposite direction - can you suggest a better way?

[@MrIzaks]

@glyn hodges Thank you Glyn. i'm running few intial tests right now (motors are on the table) and not sure I can trust the results without load or precise way to measures lost steps etc... maybe need to buy couple more drivers.

[@MrIzaks]

@glyn hodges this is my first CNC build. decided to build MPCNC and once i gain experience and know exactly what i want, i will use the stand alone controller and stepper drivers in the new chasies and get Nema 23 or 34 motors for the new build. today i use small nema 17 60oz motors so i figured for this build i can get by with 1.3A RMS per motor. didn't see any problem (current wise) connecting 2 motors to one DM542T. I still dont understand the limitation. if i have driver that can push 4A and I connect 2 motors that take less the 3A together - what could be the reason for skipped steps?

[@MrIzaks]

​@glyn hodges thank you very much Glyn! apprichiate the explanation. will order two more setppers drivers.

[@hazmatt_]

Thank you, this was very helpful.

[@thepurposeofmyexistence2511]

Aaaaaahhhhhhhhh!!!!!! Thank you :)

[@julessteiner4840]

Thanks a lot.... I hope IT works for my Project...

[@julessteiner4840]

Perfect .... It is running

[@CNCARTGR]

Excellent explanation , but i have a question. If we have two stepper motors with 3amp each how can we calculate and set up dip switches ? Must we have set up dip switches to 3amps or to 6amps?6 ams?

[@d_dadang5467]

i'll help to answer, its must be 6amp, cause that basic stepper motor used coil in the inside and the coil formula same like resistor formula. this not need to more voltage just amp

[@Nadeem610]

nice work

wow, excellent, it was very helpful, thank you very much!!!

[@hardtechti5038]

Great, needed this at very time. Thank You!

[@doc_ineeda_win5834]

ty so much for this amazingly quick but efficent video you rock ... subscribed and liked exactly what i need for my laser project only question is how did you hook it up to the control board from there, i need to run 2 motors to a board that only has one spot for y axis

[@ESE.999]

You are really amazing

[@jfairplane8520]

Is the load of both stepper need to be way lower of the total of the driver ? very Nice.

[@amirmaulana]

simple and clear

[@ENITech]

Great

[@95machine29]

this is series wiring?

[@tonyt8807]

Why did the nearest motor move first before the other @ 2:54?

[@forthewin84]

Maybe it slipped

[@rakibhasan9225]

many many thanks.

[@sotm2]

Are you sure this is correct?? To reverse a stepper motor don't you only need to switch one pair?

[@paulzacharias5784]

Will the motors stay in sync? I wired mine like this without any load, just the motors facing each other with tape on the shafts, and they seemed to slowly go out of sync. Will they act better with a load on the gantry?

[@khaled4282]

I like to make is for z Axis.is this need same wirring

[@now_watch_this]

question, if i have to connect 2 motors into the same drv8825 driver, and i have calculated each driver al 0,65 amps, should i modify vref to 1.3 amps because i am connecting 2 nema 23 motors on it?

[@casplas0301]

@Saul Ortega Then ..how do you slave stepper motor using TB6600 AND arduino?

[@m.f.q9443]

Have a confusing Pls clear Is connect a-to a- on driver and a+to a+ If any wire i mean motor a- to driver a+ connected have run or not ?

[@GirishMurthy1986]

Not recommended for two reasons: 1. TB6600 will be over loaded 2. Current Distribution will be uneven and motors WILL go out of sync

[@othnielhamonangan8839]

hello friend, I ask for a detailed wiring diagram for 4 DM556 drivers and 4 stepper motors. Thank You

[@usernew1764]

and How to Wiring two Stepper motors on a Single Axis Spinning the same way with Single Driver

[@glen.simpson]

yes, I need this, essentially two pinion bevel gears on the opposite sides of main drive gear. Can this be done similarly? Seems there;s some debate here whether you can run to motors with one driver and signaler, as displayed here. WHat is displayed here is clockwise/counterclockwise and vice versa in reverse, and I need, clockwise/clockwise.

[@plongkie224]

My, God its very helpful.. does this also work on arduino? I mean same circuit for and arduino board and g shield?

[@abilashchakaravarthyrajase8109]

hi, nice video, will it work the same way if i have 2 stepper motor attached to different drivers having the same pul and dir single from the board give to both the drivers but just inverting the wires A and b in the drive not directly connecting it to the stepper motor. please help

[@danokmec6993]

1.8 nm is enoght for wood miling ? 150x80 cm table :) ?

[@trendremixx]

yes, but I rocemmend at least 2.2 nm

[@moorthimoorthi3908]

Wooow good

[@galactussnaxus1541]

Can i control 2 seperate Nema 17 Steppers one for y axis and another x axis with only one TB6600 driver?

[@DogSerious]

No

[@TheAusherGuy]

I got 4 colored wires coming from my motor. Yellow red blue green. How do I know which one is a+ A- B+ b-?

[@issambatti9836]

You can find color identification on the constructor documentation.

[@azrulharis3323]

Try connecting 2 wire and rotate the motor, if it heavy, means it a pair of +&-

[@electromechanicalstuff2602]

How about 2 drivers on one motor? Need 8 amps but an 8amp driver is $150+ Can i run two 4amp drivers in parallel to one motor?

[@isettech]

You can sacrifice speed and wire them in series. For example without reversing, A+ of one motor to the driver and A- to the A+ of the 2nd motor and the 2nd motor A- to the driver A-. Do the same for the other phase. To reverse the 2nd motor, swap just one pair of the motor windings. For example swap B+ with B- on the 2nd motor only to reverse it.

[@sebastienfaurez9304]

What size and amper stepper please

[@parampalsingh3912]

can i also use this connection on drv8825 also?

[@now_watch_this]

im asking myself the samequestion friend, have you found anything?

[@sotm6078]

Each motor should have it's own stepper driver or they will go out of sync!

[@HooPhartd]

What would cause them to go out of sync when they are receiving information from the same device simultaneously?

[@muhammadshah7349]

is this safe manner to run two motors on single driver board????

[@joruf81]

No, it is not safe, it is better to wire it in series, otherwise it could damage the control unit!! But it is allowed to put each half knowledge online

[@m3chanist]

@@joruf81 Wrong, the controller isn't a source of infinite current, it is a current limiter, take your own advice.

[@asgharrezaei0138]

My dear please give the wiring if both direction are the same .

[@sumolartsandhandcrafts209]

But what about ampier?

[@raeauker9884]

Looks like the stepper motors are connected in series so this dosen't affect the (Ampers) but instead (Voltage)

you can't

Why dont you study full information in art witch art soft isuued about cnc sys and the axess with 2 motores in long gantry and how slave the axesses .

[@kmgwoodcarvingkatareddy1619]

Yka 2811ma stepra

[@venko3211]

Please update Same direction diagram. I need double y axis direction diagram

[@mattivirta]

better use both motor own driver, drivers have cheap, and share step and dir pin controller to driver wires only. etc, y step go to driver 1 step AND driver2 pin step, same dir. go controller y step go driver 1 AND 2 dir pin. both drivers read same signal what come out at controller, better than swap motors wires.

[@sotm6078]

You should learn how to cross wires in a schematic.
