Almost bought a tevo bc of you, but I instead purchase the motherboard to use in my DIY 440x440 big printer build and this video helped me a lot getting it to print very good and fast prints, Thank you for the effort and take care.
the best video about adding a Z axis on tevo tarantula. and the best way is to connect on the free port, since both parallel and series are "second best" options...
Hi, I use lithium grease but you can use any bearing oil for that. The disadvantage of the oil is that will fall down and eventually drop on the table. But there are some oil dip trays in thingiverse you can print and add. www.thingiverse.com/thing:1530711
Don't we need another "oldham" protection for this axis so this motor is killed too if obstacle? Will it be the same if so, or some part must be mirrored? Thx!
Hi, Yes...if you want to add protection with the oldham, you will need to print a second one and install it with the new leadscrew. No need to mirror parts. it's the same thing for the second one.
Thanks for your answer and your videos - really inspiring! Can you tell if this particular mod with the second Z motor worth it ? Is there a definite improvement or only minor/placebo ? Thx!
Hi, In my opinion it's worth it for many reasons. 1- it will maintain your horizontal profile bar always horizontal. The up and down moviment will be controlled and perfect. 2- With only one leadscrew, you need to tight real good those eccentric nuts so that the horizontal bar gets fairly horizontal and it stress the wheels and might reduce the bearing and wheel life time. 3- I always need to use an oldham coupler to prevent Z banding. When i installed the dual Z i didn't have to use oldham couplers any more. This was proof for me that the moviment is much better.
Hi Ruiraptor Your tuto are practical I thank you for that. I am entering to mount a second engine on the Z axis, I have to connect both in parallel because I am also on the points to install a double extruder. Could say to me, the things to change (Voltage, firmware ..) so that both run parallel to the connection Z. I try to change the current and do the wiring. And either the engine remains on Place, be it turns with difficulty without counting this noise that does not reassure. Would you help me on this?
Hi, i read somewhere that having dual z motors can introduce such issues as one of the motors skipping steps or something like that. And that it's better to use a single motor but to use a belt system to drive both z axis leadscrews. I'm a complete amateur at mechanics and electronics and don't even have a 3d printer yet but i would be interested in hearing your opinion about that.
Hi JeikoNYAN, I also have the same opinion that using a single motor with belt is a better method but that does not mean that the other options do not work. I’ve been using a dual Z (two motors connected to a single driver) for some time now and never had any issues. The only thing I might additionally done (but had done it before the upgrade anyway) was to increase the current output of the drivers. Since i'm connecting both motors with the same driver in a Y connection, i'm also sharing the current. Therefore, the current adjustment prevents the motor from skipping steps.
i am interested in the dual z set up, my board came with a bad z axis driver and I'm still waiting for a replacement. I attempted to adjust the pot on the z driver, but no matter what position, it has 4.96v! the motor works fine connected to y driver, so i need to make it think i want dual z steppers, but really i want to connect Z motor to E1so i can use this giant paperweight. any suggestions? i download the firmware from tevo, but has no tab for configuration_adv.h in it.
Hi SubieLand, If your Z driver is faulty (and you are not using a dual extruder) you can use the spare driver to drive the Z axis and use the supplied parallel cable and connect it to the spare working driver to drive both motors. I understand the fact that you prefer to use 2 drivers (one for each motor) but one driver for both works just fine (that’s how my printer is working). In your firmware you just need to enable the dual Z option and you will get both Z drivers working. Don’t use the TEVO firmware…use the community firmware instead or the more recent RC8 (posted recently in the tarantula facebook group).
I brought dual motor about 1 year ago. Before I installed the motor, whole axis were working, included filament motor. After I installed, whole axis wont move at all. Even I tried to control through computer, still nothing. So I decided to upgrade the firmware, Marlin. The display said the motor aren't connect with motherboard, actually it is.
@ruiraptor I brought the motor from TEVO's amazon product. Link: www.amazon.com/gp/product/B073YMBNTC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 And I looked at wire pin out. All of them are exactly same as other
Hi Chi Cheng, You can use E1 but you need to flash the firmware because that port is not assigned. Regardless of the firmware version, you need to edit the firmware to assign the E1 port unless the new firmware already has the E1 assigned.
Hi Rui ! I seem to have everything ready to make this install but I do not have the parallel cable. Could you please tell me the cable specs so that I can search for it ? Of course It would help a lot if you could recommend a good supplyer. Thanks and congrats for your 10.000 susbscribers !
what firmware are you using ? In marlin 1.1.x i'm not able to see the same code as you . on the commented hints from developpers, it says next unused E stepper will be asignated to Z motor . but is Marlin that smart ?
Hi, I'm using the community 1d version. Are you planning on using the extra driver for the new Z motor? I'm using the same driver for both with the parallel cable and works perfectly.
Hi, There are different opinions about that it it always raises discussion :) In my opinion, i prefer to have the same driver to move both motors (using the Y cable) as this way both motor will always move in sync. At the same time, i made sure that the output current is correctly set (you can see my other video about how to adjust the current of the stepper motors) and i have zero issues with this setup.
Master of code 101 , I currently use the community 1d version. it works great. There are other more recent versions but they are RC versions (Release Candidate). some may have bugs but you can try them. The latest is the RC8.
Thanks, I love your video's as always. But one question, Do you see a difference in quality having dual z axis? Is this a highly recommended improvement?
Greetings Jósep, There are some things i notice with this upgrade: 1- The horizontal bar is always straight and leveled 2- Both couplings share the entire Z weight (as you know the motor coupling is flexible and is stretched due to the weight ) 4- Smooth movement thanks to the perpendicular movement of the horizontal bar - Also means less stress on those 8 wheels. 3- The combined movement reduced the Z wobble (for my first test print i wasn't using the oldham coupler and the dual Z nut mod was incomplete). 4- If you are planning on getting a MGN12 rail for the Z axis then i recomend you have the dual Z motor to release the stress on the carriages too. If you have a combination of oldham coupler or dual Z nut + a bearing mod that supports the Z weight, you might get away with it just fine but will always have the unleveling of the horizontal bar and stress on the 8 wheels.
Thank you, I will then definitely do this upgrade soon, and then wait for you to show us how to add the mgn12 rail to the z axis. Happy holidays Master :)
I was wondering if the platform of the wheels in the opposite z axis to the motor (the one in the 2020 frame) was more large, that would help to the stability? I'm asking because i want to design my 3d printer using similar system.
Hi there, I don’t think it will make a difference since both leadscrews are installed near the edge of the horizontal bar. If you had a single leadscrew installed in the middle, for example, then yes…but not in this case.

Hi Woody,
Thank you for your feedback.
Which option would you recomend for the stepper motor power? You give 3 options, but I don't think you indicated which would be the better option?
Hi Glen,
I'm using the cable that is provided with the tevo upgrade (parallel cable).
ruiraptor Ahh ok. Sorry I misunderstood, I didn't realise it came with a parallel cable.
May i know which connection did you use?:) parallel, serial or thru the E1 port?
Also, where could I get a cable to fo the parallel configuration?:(
Great step by step video! What did you use for grease and syringe? Thanks

You can use E1 but you need to flash the firmware because that port is not assigned. Regardless of the firmware version, you need to edit the firmware to assign the E1 port unless the new firmware already has the E1 assigned.

Hi rui, i've install a dual z kit but with the wire given in the kit my motors turn in oppsite direction, any idea ?
Hi,
You can reverse the wires in one of the motor connectors (cable) to fix that.
It was my first idea but how to do that ? by pairs ? ABCD => DCBA ?
Thks a lot.
That's correct
