A practical easy to follow needed instruction which I will be using on my new mks 1.4 board
Thanks. Just remember VScode with Platformio IDE is becoming standard for Marlin firmware setup.
Worked perfectly, I have to say that in the newer version of Marlin I saw no mention of Dual Z stepper it on asked me the number of Z stepper I wanted to use, other than that, flawless, thank you
You're welcome.
Hello Geryguild, i cant find where i can set the Number of Z-Extruders to two. Could you help me or send the exact pronounce where I can do that? Greetings
@@manuelrenner3671 in the configuration_adv. h search for #define NUM_Z_STEPPER_DRIVERS and change the value to what you want
Thanks I really really needed this tutorial
You're welcome.
I have an older prusa that just has the wires spliced together with one plug into the z pins. Whats the difference between splicing and the way you did it and why did you do it this way?
Impressive job, and simple shown, love it
Thanks for sharing😀👍
You're welcome.

Hi Edward
I am in the process of making a vertical down DLP 3D printer.
I have bought a 32bit Bigtreetech Circuit board. I want to modify it for this project and I’m wondering if you have any thoughts and ideas on how best to do this?
I want to use the heating bed for the heated resin tank and servomotor for the Lens shutter. The stepper motor is 2.8amp and will be driven by a TMC5160 stepper driver. It can be configured up to 256 microstepping and it all needs to work with creation workshop. I’ve spent ages trying to sort this out! I am not a programmer and I’m a newbie to coding!
Any help or advice you can offer would be much appreciated.
thanks
Matt
Marlin firmware should have all or most of the functionality you may need. Good luck. I've not yet created a resin printer.

hi , i have a KEYES control board MKS Gen V1.2 on a bee prusa can i use marlin 2.x or i have to use only the 1.1.0
Tkx very much and nice video
8 bit boards can use either Marlin 2.0.x or 1.1.x. 32 bit processors can only use Marlin 2.0.x.
Hi Edward...
i'm trying to flash the firmware but i read this
Marlin_main.cpp:356:7: error: expected ')' before '.' token
(card.cardOK card.initsd();
^
exit status 1
expected ')' before '.' token
How can i resolve?thank you!
It might mean syntax in that line is missing a, ")".. try downloading a new Marlin firmware and recompile.
In the newer version of marlin, i tried two find the line dual z stepre but it doesn’t seem to be included, could you please help with this because it got me really frustrated
There should be a link for Discord and we're all in general chat.
Hi, friend, great tutorial. I have a issue. Im making a CoreXY. The axis Z is moving by two motors nema 17 with two drivers TMC2209. One to Z axis and other to E1. The motors move to different speeds. Could you help me please? any tips?
Hi Rodolfo! I have the same problem. Have you solved it? Can you say to me how can I set the steps for the second stepper (E1)? Thanks!
You might be able to compare configuration to example configuration.h and configuration_adv.h be careful as they are just example files.
Hi great video thy
How does marlin 'know' it have to be use e1 as the second z stepper?
i want to use a second Y motor with a independent endstop ( so i can square things out)
greetz Edwin
It's possible to use E1 as a second Y stepper. As for the second endstop not sure why.
Normally one endstop in each axis x, y, and Z need a zero point for homing. Adding a second endstop might not work in this case.
I did read that you have to say in marlin that you have to say use _e1diag_ as second y axis as endstop
Edward at 6:30 in you skip defining the E1 defaults - DEFAULT_AXIS_STEPS_PER_UNIT, DEFAULT_MAX_FEEDRATE and DEFAULT_MAX_ACCELERATION. Was this because you were accepting the A4988 defaults for your E1 channel setup - or does Marlin copy the Z Axis values to E1 when you add the Z_DUAL_STEPPER_DRIVERS definition ? I am using TMC2208's in UART mode so it will makes a difference. Thanks Bob
E1 is a default setting for normal printers. It may change based on configuration after calibration. I have a video someplace in my playlist.
Bob Carter thank you for your comment, I have this issue as I have the tmc2208 drivers. Basically E1 either turns faster or goes further. I have not solved the issue yet. I would like to know how you solved the issue.
@@lucasvandelogt5126 Hi Lucas - firstly I am using a BTT SKR 1.3 and not an MKS Gen board. I have yet to put the TMC2208's on the Z Axis (I have tested them working on X and Y in both STANDALONE and UART) but I have yet to try them on the Z Axis. I do have that working currently with a pair of A4988's (as it is cheaper to screw those up). In configuration.h I have defined Z_DRIVER_TYPE and E1_DRIVER_TYPE as A4988 (Z2 remains commented out). I have set only 4 values (ignoring E1/Z2) for DEFAULT_AXIS_STEPS_PER_UNIT, DEFAULT_MAX_FEEDRATE, DEFAULT_MAX_ACCELERATION. In configuration_adv.h I have uncommented Z_DUAL_STEPPER_DRIVERS. I had a similar problem to yours on X&Y and I ran that down to only one of the TMC2208's actually being in UART mode and running 16 microsteps. I had an issue with the other and so it was running Legacy and with no jumpers present defaulted to 8 microsteps. Check your soldering on the TMC2208 and the UART connections.
@@bobcarter6143 I solved the issue by putting the motors in parallel
@@lucasvandelogt5126 Lucas that is one way to solve it - the ANET A8 V1.5 mainboard I am replacing does just that, shares an A4988 across 2 Z motors - and I have bought several parallel splitter boards of eBay just in case - that said this morning I moved the two UART jumpered TMC2208's from X&Y to Z&E1 on my SKR1.3 reconfigured it and recompiled. Marlin is not reporting any TMC_Connection errors and is turning both motors in the same (wrong) direction at the same rate. I forgot I needed to reverse the direction moving from A4988's so changed just the INVERT_Z_DIR ignored E1 and that recompiled still turns both motors the other (right) way. So Marlin appears to be ignoring some/all of the E1 settings and just duplicating the Z. Good luck Bob.
Thanks friend 😊
You're welcome.
Would this serve for a correct alignment of Z in marlin? with the line that says #define Z_STEPPER_AUTO_ALIGN
Maybe, but would independent steppers will always have alignment issues.
@@EdwardBraiman
So you recommend using a single driver for two motors? Thanks for the prompt response!
Np.
Edward, i followed your tutorials, my dual z stepper was working fine for 1 year.
I didn't use my printer for a month and yesterday when i ran it, my E1 motor(which is dual z) is rotating too much Ex: if i move z axis for 0.1mm E1 motor moves for around 1cm.
I tried re-uploading marlin firmware. Doesn't work
Changed drivers, and adjusted current.
I checked E2 motor and cable, all are good.
Just cant figure out what the problem is, can u help???
Different steppers or NEMA 17 motors?
@@EdwardBraiman a4988 drivers , and nema 17 motors for both E1 and Z
Are part number same on both NEMA 17 steppers?
Is there a print resume function for the board?
Should be, that's a function of available pins on board and setting in Marlin firmware.
Some printers use four motors in the vertical direction. Can you please advise how to do this in Marlin? And if you please make a video about this, it would be great. Because big printers have 4 motors in vertical direction.
I've shown in some tutorials in advanced boards how to do this.
@@EdwardBraiman could you please tell me in which video you speak about four motors in the vertical direction? i check video titles, most of the video tiles are "dual z stepper" and i looking for quad motor in z axis.
i also check Octopus board and can't find how to setup 4 motor for z axis.
please help me about this.
thanks.
Hay! Im using some TMC 2208 and this error keeps apearing "TMC2208 or TMC2209 on Z2 requires Z2_HARDWARE_SERIAL or Z2_SERIAL_(RX|TX)_PIN."
Any idea how to solve it??
Thanks!
Post your configuration for configuration.h and configuration_adv.h in Discord and I'll look after work.
@@EdwardBraiman Thanks man!! I'll do it
You're welcome.
Im running head first into a wall. I have Marlin bugfix 2.0.x and Z_Dual_Stepper_Motors are nowhere to be found!! Please help! Im going crazy trying to figure thisout
Use non bugfix build. Bugfix is a development branch it's not stable.
@@EdwardBraiman I even tried 2.1.1 & 2.1.x. Neither show these options. What am I missing?
There's a Discord link on channel. Explain your issue in general chat and I or someone else can help.
Thanks very helpful - where is Part 2?
I think I took it down for some reason and have not record a new one yet. Also BTT added configuration files, so later this month I'll update tutorials again.
Good video, thank you. Can you do one with dual z, dual endstops?
Soon. I'm working on about five tutorials in my queue and then will start to add more to do.
@@EdwardBraiman I am just curious if it will help keep the bed level if it know to adjust 2 steppers. Thanks again.
Steppers currently will only move in parallel.
@@EdwardBraiman So I was thinking of dual z steppers/rods, dual z stepper drivers and dual z endstops. In Marlin, especially bugfix 2.0, there is the capability to re-sync thereby re-tramming the bed to the x-axis. Someday, when I get ready for a full upgrade of my E16, I will give it a go.
Sounds interesting. I've not yet digested the whole firmware, but I would like to examine it soon.
hola tengo un problema con el conector del termistor. esta quemado el pin . quería saber donde consigo el archivo pins.h para poder usar el conector del termitero del segundo extrusor . muchas gracias
El archivo de pines que busca es pin_MKS_GEN_13.h. es posible que desee averiguar la causa raíz de por qué el termistor se quemó en el primer pin para evitar una repetición del problema. Buena suerte.
@@EdwardBraiman disculpa no encuentro el archivo. se quemo el conector por que no tenia la protección plástica y se me cruzaron los cables provocando un corto. fue un grave error.
@@rodrigov424 La ruta del archivo puede verse así para Marlin 2.0.x ... C: \ Users \ ebraiman \ Downloads \ Marlin-2.0.x \ Marlin-2.0.x \ Marlin \ src \ pins \ ramps
I follow these steps exactly and changed drivers to drv8825 because thats what im using but i get an error when compiling.
What's the error?
@@EdwardBraiman will try and reflash this morn when i get back to my shop and post error
it actually flashed this time... I must have done something wrong the first couple times I tried. now to test on the stepper motors. I will report back
all motors are working as they should print head is getting hot but im now not getting a hot bed.

Please do you have any advice for me to solve this issue?
Do you have any devices connected to 3d printer board? What board do you have selected in Arduino IDE for chipset? Have you considered using VScode with Platformio extension?
@@EdwardBraiman Thanks for the quick response. The board is on it's own with just the stepper motors plugged in. Board selected is Arduino Mega or Mega 2560. I don't know what VScode is. I am using the DRV8825 steeper drivers if that makes any difference
I've sorted the problem. I had the wrong COM port selected. When i checked the COM port in Arduino Port 1 was ticked but it also gave me the option of Port 4 which i have just tried and it uploaded. Now to carry on with the rest.
In my playlist for this series there is a video on how to install. It should make it easier to work with. Is almost the same, but has a configuration file called platformio.ini. are you able to connect to the board with Pronterface?
@@EdwardBraiman i connected to the board in Pronterface and when i moved the motors 1mm they turned. Tried 10mm and they turned again but when i tried to go back to turning by 1mm sometimes they were hesitant to turn then 1 might turn but the other didn't. There was also a bit of a click coming from the board.
I HAVE MKS ROBIN 2.4 BOARDS AND MARLIN 2.1. Z2 STEPPER MOTOR CONNECT TO E1 NOT MOVE.PLEASE HELP
You'll need to set up the stepper for E1 in configuration.h and then enable E1 in configuration_adv.h for E1 as a second z stepper. Note it may fall out of synch with other stepper motor as the calibration of each stepper may vary. It might be cheaper and more precise to split the output of the stepper with a stepper divider board in one of my SKR 1.3 videos it's explained. Hope this helps.
@@EdwardBraiman HOW enable E1 in configuration_adv.h? CAN I SEND MY CONFIG FILES FOR U? I USE MKS LV8729 DRIVER AND I WANT DUAL STEPPER DRIVER FOR Z AXIS
@@EdwardBraiman Hello, thankyou for the help. but how to set the E1 as the second z stepper in configuration_adv.h? i cannot find it
The Marlin firmware may have changed since the recording of the video. Which version of Marlin firmware are you using?
@@EdwardBraiman im using Mks-Robin-Nano-Marlin2.0-Firmware.
Here's the link: github.com/makerbase-mks/MKS-Robin-Nano-V2.X/wiki/Marlin_firmware
I found how to use E1 as Z2. Here it is: NUM_Z_STEPPER_DRIVERS 2
But when I flash it in, it still doesn't work. Do you happens to know why? Thankyou to reply!
At 0:58, you said E0, don't you mean E1?
Probably.
