Currently I'm working on rebuilding a large CNC machine. The machine’s axes weigh up to a couple hundred of kilo’s. This amount of mass needs a lot of power to accelerate and decelerate. To make sure I had enough power I went for the biggest motors I could find and that turned out to be Nema 34 closed loop stepper motors.
The Nema 34 closed loop stepper motor ,from this video, comes with a HBS86H stepper driver. The driver can take 18-70 volt alternating current or 24-100 volt direct current. I’m using a 48 volt direct current power supply for my setup. Closed loop stepper motors have an built in encoder that checks every movement the motor does. Is there a difference between the amount of steps the motor is ordered to do and the measurement from the encoder than the system corrects the mistake automatically. Closed loop stepper motors are for this reason very reliable even when pushed to their limits
The initial plan to control the Nema 34 closed loop stepper motor was with use of mach3. I ordered a Nvem mach3 motion card but I couldn't get it to work. In the end switched to an Arduino nano running GRBL 1.1 and Universal G code sender. It’s a much cheaper alternative and so far it's working great.

The settings section helped me a lot. I was steady at 500. I saw 1400 RPM thanks to you. Thanks dude.
It is funny that most ppl use the VCC as the common, in mine i'm using Gnd as common and connecting the En+, Dir+, Pulse+ to the board. But also, i am using a different board.
It worked. I was having issues since I confused that the 24V/5V switch, I thought it was 24V since I was getting this voltage from my Power supply. It was 5V, because i'm getting 5V from the board. -_-
Spent 5 hs in this. Learning.
Wonderful, tks for sharing.
Now this one beats servo at any time
Attention to the NVEM card.
The card would seem well made, but it has serious software problems:
the plugin that is provided does not work correctly, in fact it has serious problems with soft limits and with home switches (this problem does not concern only my controller but all of them, in fact reading from the forums these problems are due to the plugin made really badly, also the manufacturer no longer gives support on this product, so there is no solution to these problems.
Below is a list of the problems that this type of card has (NVEM4 V2)
Operation problem: crashes, disconnection from computer, soft limit not working, MPG + dangerous emergency (with emergency not restored, the machine still moves using the MPG).
If it is still possible, replace it with another controller
Yeah, have replaced it with an Arduino. I wish I knew this before...
That's what I thought when I saw the card in the video. Actually I don't know of any Chinese card that works correctly with Mach3
@@MBcreates
I am going to use 3 nema17 7.2kg torque motor is 1 lrs75 24v power supply enough for it?
@@MBcreates How on Earth could you replace it with Arduino, given how slow Arduino is to send pulses??
Nice video. Just ordered the same motors for my big cnc router.
Nice 👍
Loved it
How fast are you able to make it turn with your controller? Really great vide0 !
Pls can I use it for sliding gate opening... I mean with a suitable gear box... Can it be powerfull enough to slid 1200kg sliding weight.....
Hello, what is the difference between a hybrid stepper motor running at 3 phase alternating current and a hybrid stepper motor operating at 2 phase DC, please help and thank you very much
I have thought to get a pair of these closed loop sets for my 6040. Very valuable to see them run and controlled. Sad that the BOB card is a fail. Please let us know a good inexpensive Mach3 BOB card.
Can you say me what is your microsteps setup driver? A pic of microswitches would be fantastic. Thank you.
Is it possible to go 36 degree and back and repeat up 30 times back and forth in 1 second? or how much back and forth times in 1 second?
How does the controller correct any missed steps? Does it stop the other motors until the steps are correct? How much error will be seen in the cut when this happens? I great video would be to cut a circle and a diamond while holding an axis to purposely cause a misstep. It would be cool to see what happens!!
Everything is done in the blue driver box. From what I understand (haven’t had time to completely read in on the specs) the driver corrects for lost steps in real time and you won’t notice anything while the motor is spinning. I suspect that an alarm mode is triggered when you purposely block an axis from moving and the driver shuts down but I’m not sure on this.
Great idea on the test. I will keep that in mind :)
@@MBcreates The driver has a simple PID controller. Lost steps are corrected by speeding up the motor to catch up. When the error (difference between the reference signal and the ouput) becomes too large, the driver will stop the system and return an alarm. This already happens when the motor is stalled for just a second. You can configure this yourself. The default gains of the controller are fine for normal use, when you want high performance with high accel/deceleration times you really want to tune the controller to your needs.
I have the same setup from Leadshine. I believe the one from Banggood is just a knockoff of leadshine but I guess is should work the same.
Thanks Buddy, I'm also making my Router!
Nice video, I've received 4 days ago my 6040, I designed and sent the files for a new work plan to a local company. Could a small vise be a good idea to fix the pieces? I think I will work mainly aluminum
One more thing, my fourth axis motor is pretty weak, is it normal or my motor/ motor driver is damaged?
Simone Chiarlo do an unboxing, review, problems you’ve encountered and many more things. I mainly use co2 lasers and 3d printer and I’m looking to get a 6040 for my first cnc but there are only few videos and I’ve only come across 1 unboxing.
Is that key on the stepper motor removable? I'm trying to find shaft connections, and I am surprised to see that it is quite difficult.
bro, lol, look up "couplers with keyed shafts" mcmaster carr will help you.
Can you show me the wiring diagram from driver to stepper motor 😅
what software is that u controlling 3 axis with it !
Hi I have 4 of these motors , I can't get them to move at all, I can't believe I have 4 bad motors or drivers
Any ideas??
I have set up in mach3 pin 2 port 3
Dor moves but motors do nothing.....
Very cool these tests, what was the Arduino software that you used in this video! Congratulations
Thanks, the Arduino is running GRBL V1.1 and the pc is running Universal G-code sender (platform version 2.0 nightly)
hola, no necesitas enable para mover el motor? Yo tengo un problema, no se mueve el motor y hace ruido cuando no esta conectado enable, me podrías ayudar? hss86 nema34 12nm. Muchas gracias!
Great video! 👍
I'm interested in that same nema34 motor, can you please say what max rpm you were getting? Thanks! 🙂
Hello, is it necessary to use the RS 232 cable for the safety of the CNC machine to work with the Mach3 program or is it only used to show the values? Please help and thank you very much
Can we run these closed loop stepper motor with a simple stepper driver like tb 6600 wi5hout encoder please tell me answer or make a video on this with a run closed loop stepper motor without encoder
He is not your slave.
can we control two steppers one 12 nm and other 2 nm(i m not so good in knowing standards), with the same controller , for robotics use
How many hours does nema 34 work continuously without heating?
It heats up immediately, but the question is, how do you cool it down :)
That NVEM has a super bad reputation ... Went for MESA.
Thank you for the video
NVEM is the problem belive me
I have 3 of them
Usb and ethrnet type and its a piece of rubbish
I wish if i can help some one with this comment and you can see my chanel explain the driver
48v 1000w supply for 1 stepper motor or multiple stepper motor setup?
can you control these with an arduino?
Much better choice: 3ø Mitsubishi Servo Motors
They look nice. Have you worked with these servo's before?
@@MBcreates yes with Mitsubishi MRJ2S-70A 750W Servo... and may be new plan with 1.5kW or 750Wx2 at Y to move table...
@@MBcreates I used servos as they are much better choice for pro CNCs, as stepper motor's armature got play after few time... so to use servo in 3ø mode leads to efficient system and long term usage... not only because its armature is well built but also better encoders, control so on... any professional MACHINE!!! (Except toy or router or bad Chinese) using steppers??? I also used the same product you're using here... when I used open loop stepper/encoder less stepper with this driver it fries the driver... if you're looking for less budget then go for it... if professional and much better product then servo is much better choice!!
