Super helpful for setting up a HSS86. Thanks for posting.
You are right on the assumption that current is dependent on the error. So if motor sits right where it should be the current will be quite low. That is why they will usually run cooler (and you will save some energy in the process too).
Thank you for sharing. I was having trouble understanding the "open/close" loop side but now I understand that the cheaper way to hybrid steppers is this way. The return side of the motor is just an error condition with no return positioning available. You made mention of possible use of the rs232 side, but it really looks more like ft232 than interactive 232. Ft stands for file transfer. The difference in return/settings compared to other drivers is you get what you pay for. Again.... thanks
Thankyou so much again you are a great person!
Thank you so much for you super helpfull video !!! you really help me a lot making this video!! best whises and best of lucks for You, greetings from Mexico City!
Thanks for your research. I still have to try this one day.
I already have the centroid acorn stuff , and some steepers . But I like the smart ones better.
Good info Franco, was wondering what the ac/dc power input was all about on the larger drivers. This will make it a bit easier when the time comes to actually your kit installed and cranking.
God bless you Franco !
You're correct about the amp setting in the software, however if you chose to run a motor that had a lower amp rating, that is where the importance of being able to set the current output will come in. While it's true that the driver is "intelligent" and will vary the current as needed, they WILL send more current than a motor is potentially rated for in attempt to make up for the felt resistance sent back to the driver COM port. More or less the setting should be no more than the motors highest current rating as a top end governor.
Hi, THANK YOU! Really, really helpful. BobUK.
thank for all hard work
you been grade help to me.
thanks
SADEGH POURYAN I'm glad you found the video helpful.
hi
i want to ask you , do you think for three motor we need three spread power supply or one its iok for three motor
Hi. You have to make sure you have enough amperage. You can have a single power supply as long as you can provide enough amperage to all of your drives. Divide the wattage of your power supply by the voltage it delivers and you will have the amperage. A 350Watt 36Volt power supply will provide about 9.7Amps.
thanks again
If you really want to get the best performance out of these I wold suggest researching how to tune control loops. I was curious if these drivers could be tuned. The big selling point of more expensive options like the DMM drivers or the ClearPaths is that their software will auto tune the motor under load. The leadshine software you have to manually tune the PID loops which can be a pain for first timers. And not very many DIY types know that PID tuning is necessary to reach the precision and performance potential of a closed loop system. People see closed loop and the cheap price and think it will be easy to setup. However spending the time to learn how to tune them can be very beneficial when it comes to matching the performance of much more expensive options. Im really surprised the eBay seller does not include information on the software, because without it there is no way to tune the PIDs. I'm guessing they are setup to max out the potential power of the motor when making corrections to the position loop, because those are some crazy powerful motors they are selling. And I would guess 99% of these motors will be coupled to ballscrews which acts as torque multiplier thus minimizing overshoots in the default PID loop.
Yes, you're right, on ebay / amazon and even on many sites, they sell engines, drivers, and more without knowing anything, often they are even fake leadshine or counterfeit, product random codes, photos of other engines, a real disaster. it's true that you save, but the risk is high. I buy them on ebay because I can't afford the clearpaths, too expensive really ... the only positive thing is that I pay with paypal, so if something goes wrong I open a dispute.
Elite Machine Works can you make a video on how to tune these?
Thanks a lot!! It's being really helpfull!!

I see the videos from 2017 but what the f thanks for the due diligence awesome on the serial you should be able to use the terminal server like putty to connect to the controller software is great now that you have found it documentation is irreplaceable great you found it,, I noticed recent comments from my experience if you're going to mess with the holding torque consider your working scenarios less holding of an access means is we're talking another axis we can pull it out of position... Depends on the rigidity of machine but if you find tolerance is an issue sometimes holding torque or current on the axis is needed to be higher.... Because you're talking about close loop it's important to build a system that can be effectively controlled..... Peace
Excellent video, many thanks.
Hi Franco, good video. I'm trying to program the drive but don't have the RS232 adapter cable.
Do you happen to have the pinout of your cable? Is there anything more to the cable (any resistors or anything inside?)
Never mind on my questions I ended up ordering the nema 34 12nm from fast to buy. I figured I’d stay with what you have and that’ll help me hook it up. Thanks for your time sir!
Thanks for choosing fasttobuy
Hey Franco, I see they have a different driver, HBS86H, is the software the same, or is there another driver to download?
Closed loop steppers are a variation of servomotors (en.wikipedia.org/wiki/Servomotor). They use stepper motors to rotate the shaft rather than a simple DC or even AC motors in "regular" servo.
In typical servo design the output of the encoder tells the controlling computer the position of the motor shaft or carriage on the linear rail and the computer spins the motor by controlling direction of rotation and duration of the power cycle until the desired position is reached.
Open loop steppers receive a pulse of current in specific direction which rotates the shaft by a few degrees, based on the design of a specific stepper motor. A sequence of those pulses in rapid succession makes the stepper motor appear to turn continuously. Variation of the frequency of the pulses appears as variable rotation speed.
But the computer sending pulses to the open loop stepper motor does not have the feedback from the motor if the shaft actually moved. So if something blocked the rotation or the pulses came faster than the motor could rotate, the machine would "lose steps"
Close loop stepper drivers take the feedback from the encoder in the motor and repeat the pulses if necessary until the encoder indicates that the shaft is in correct position. Some drivers can buffer bursts of pulses and move the shaft at the rate the motor can handle.
Note that the computer sending G-code commands to your DIY CNC still does not know if the shaft of the motor actually rotated as it requested because the closed-loop exists only between stepper and the driver.
This is where the main difference between real servo and close-loop stepper drivers resides.
In the real servo applications the closed loop exists between computer and the encoder on the motor (or linear rail/actuator assembly). The application controlling the machine knows exact position of the shaft or linear rail/actuator.
The close loop driver can only (at this time) send an error signal, which some DIY CNC software can read to at least halt the job to prevent damage to the tool.
One can expect that in time the close-loop drivers will be communicating with the CNC software creating a true closed loop CNC machine, entering a whole new level of accuracy that could even compensate for mechanical imperfections of the mechanical components of the machine.
Last note: There are servomotors available that use AC or DC motors but act just like stepper motors and the drivers for those connect to the CNC controller just like regular stepper drivers accepting pulse and direction input.
see th-cam.com/video/dDxyaoYXxY4/w-d-xo.html
AC/DC motors hold multiple advantages over stepper motors but the control circuitry is much more complicated (=higher cost, lower reliability)
Terrific explanation. Big thanks for making that clearer than any other source I've read.
Hei I am just starting up with closed loop stepper snd I wonder if you can help me with this. Is there any connection between the lines (lpr) and the microstepping number. Say 1000lpr is there any spesifyed number of microstepping I have to set using this 1000 lines encoder
The driver has a bride rectifier on the input from the power supply Transformer that changes the AC voltage in to DC before it get to the driver circuit. Using bridge Rectifier on any dc circuit allows that circuit to apply AC or DC to it with the DC being the only voltage coming out of the bridge rectifier, the DC will not be rectified and flow to the dc side unimpeded.
really great videos, keep up the awesome work, very nicely done, I purchased the same hbs86 nema 34 as you did, what was the pulses per rev set to, the dip switch setting on the drive
Hi. You have to adjust the steps per rev using the software - no dip switches on my drives. I believe the factory default setting was 4000 pulses per revolution. But, that's just a guess as it's been a while since I set them up.
Thanks!
Hey Franco
I recently bought a StepperOnline CL57T controller and NEMA23 closed loop stepper. It seems to be a clone of the Leadshine driver as well, in fact the user manual states "designed by StepperOnline, manufactured by Leadshine". Anyway I had downloaded SO's tuning software and it appears to be the exact same as the Leadshine, but without any documentation it's pretty hard to decipher. The support document you have in your dropbox is very helpful.
THANKS!!
Gary
Awesome. I'm glad I could help.
Well done sir very useful
Yes, they have control loops on position and current (12:00) Their performance behavior is different if used with open-loop drives.
thanks this video will help
hi sir great info, i was just wondering cause my driver will be able to do an ac and dc input , could yuu please point out which one is for ac and dc slot. thanks in advance
You can put AC too. If you see the driver pins where the power goes there is written AC AC on both pins.
Same on my UK 2 HSS57-60 drives, the PCB is marked with 2HSS86 V1.0 and AC on both input pins, and the casing is marked DC +/- :P I'm running them on 48V DC and so far works fine. At least after a fixed a broken solderjoint on the rectifier that prevented one drive to start...
I really found this video usefull and I gave you thumbs up!
I wanted to ask you what type of connection you are using between the computer and the cnc breakout board, USB or parallel DB-25?
I'm trying to build my own 4x8 cnc and have found conflicting info.
I'm guessing that having a closed loop should increase the need for a lower latency on USB comm ports.
Hi. I used the Centroid Acorn system which is Ethernet based.
Awesome info. Thanks

Hi Franco, thank you for this video and information. I bought the leadshine cable, but I can't connect to the drive. Any idea what would cause a communication fault? Thanks!
Mike Johnson Hi Mike. I had to install the Chinese and the English versions of the software. The English won't work without the Chinese.
Great informative video
Do you know if you can program inputs into the controller? there look to be inputs on the far side of it, I am looking to be able to program a forward and backward input on a controller once programmed. Cheers
Hi, thanks for uploading
the video very good ... I'm not very clear about one thing, these
drivers have to be connected with the RS232 cable to work in cnc or not? thanks greetings
Hello. You only need the RS232 if you want to use the software to chance the driver settings.
I have good quality shielded CNC cable in a few different sized depending on the size and Ampere of the motors. You can use any kind of wire, but there will be RF interference which can cause problems with precision.
cncpreference.000webhostapp.com/index.html
I am just getting started so please be patient. I hope to have the email address working soon. The phone number works until then. I only speak English though.
Very interesting video when looking into steppers and drives. Two things I never find with these Chinese systems that you might be able to answer: Max and rated speed (rpm) and a speed torque curve. Have you found anything like this in your search? Thanks

Running higher voltage motors.
Higher voltage requiers less current to achive the same or higher torque/wattage in a device.
Voltage x Current = Watts
You can use thiner gauge wire and longer runs with less current and higher voltage and AC power.
Franco i watch all of your videos on acorn and everything in between. Can you tell me is there any way to reset these drives without killing the power to it? Thanks for all your help on my journey I love your videos man!
Hi. Unfortunately, the only way I have found to reset the alarm status on these drives is to cut power.
Hello, thank you for your video and files. I'm about to buy 86HBS120 + HBS860H. 4 of them. The seller is suggesting a 800w 60V transformer. I don't know much about it. My worry is if I would be able to run the motors at 1000 rpm when needed. Also I couldn't find much information about microstepping and closed loop system like this one. I assume that microstepping only helps in reducing vibrations and you can't count on it for positionning. The encoder is said to be 1000 line but is this of any use? If you could provide some feedback about the motor capabilities (power, closed loop, microstepping) I would appreciate. Thanks in advance
Check this out: th-cam.com/video/5D7px0r0pUE/w-d-xo.html
The 1000 line encoder will actually produce 4000 pulses per revolution. Steppers don't make great spindle motors as they lose their torque as the RPM is increased. But, I think you will probably be OK at 1000 RPM. Especially, if you go with closed loop steppers.
Current.
The current or Amp's setting is a current limit, this limits how much current the driver sends to the stepper.
Think of this as a safety.
You can power all your steppers/drivers with one large 100A power supply, if you where to deliver 100A to the steppers and they where opperating under the correct load or strain they will only use what they need.
If you have a big heavy Z axis and the motor strugles to lift it or if you had a 1/2" endmill and had a to high feed rate, the stepper will draw much more current more then likely burning out the driver mosfets or the stepper windings.
By adding a current limit to the drivers they will behave like a shear pin to protect you drivers and steppers from being damaged when being overloaded or during a crash.
Can encoder be fixed after over volatage ,driver flash 3ces after motor move and display red light. Test with another driver and it works but 2 driver affected can this be fixed .
Hi there!Maybe you can help me out with something...I am at the final step of building an electronic leadscrew...i use the same closed loop hybrid steper motor but after connecting everything the motor does not move at all....it is the clough42 project but i used this motor and stepper.....maybe y0u can help me?
Have you looked at "Clearpath" precision servo motor systems?
I have. They look really nice. But, by the time you buy the motor, upgrade the precision and buy all of the cables and stuff, they start to get pricey. I think the closed loop steppers are a better bang for the buck (in my opinion).
Dear Franco, I hope you can help us with our problem with the HBS860H. Which motors did you select from the CNC12 Wizard? On the Forum we were advised to select the Leadshine DM series, but unfortunately we can't get motion on the motor (Model 86HB250-118B). Please can you advise us. Thanks MJR
My guess is you have a problem with the enable input. Try reversing the logic on your enable input.
Hi Franco,
Thank you for your helpful video.
The Leadshine tuning software does not seem to work under Windows 10. My multiport USB-to-RS232 adaptor has TX and RD data leds and no data is being sent. All ports work fine from Realterm. The software works fine on an old XP machine.
I just recieved a package (Jan 2018) of motors, drives and power supplies from Fasttobuy2012 , two 8Nm motors and one 12Nm. The 12Nm motor arrived with the shaft locked, which I'm working with the vendor to resolve. I suspect it took a knock in shipping and the armature is binding on the stator.
th-cam.com/video/2x_IKvZJIPQ/w-d-xo.html
Thanks Franco, that solved my connection issue!
What puzzled me was it working with just the English version installed on an XP PC I have hanging around at work for legacy software, but not on the fresh XP install I made at home. The 'Aha' moment was when I remembered I'd installed some software for a Chinese laser cutter on the work PC.
They're sending me a replacement motor..
Cool.
Hi Paul, Just a suggestion, can you run the software on win10 if you go to explorer and right click the program and then click Properties and there chose Compatibillity and then chose in Compatibilitymodes Windows XP and run as Admin.
Hi do you think the software you showed will work on a 2HSS86 driver?
Hi Franco, excuse me a newbie question, is it possible to get the data from the motor encoder? I mean EB + EB-EA + EA- to read position? i try to make a PID comparing with another encoder but usually incremental encoders only have 4 wires, is 5v voltage in EB EA?
At least on the closed loop steppers I have there is a 6 wire connection, EA+, EA-, EB+, EB-, +5V, GND, so 2 of them are simply power to the sensor. I would assume the signals are 5V as well since the sensor runs on 5V.
good jobs
How does this compare to the hbs57 with nema23 setup you had in your other video, what would be better for the 1500x1500 workbee?
I'd use the HSB57 for the router. They are the right size and you can get a killer deal on a 4 axis kit on eBay. A friend of mine used that kit on his WorkBee and he loves it.
I noticed this is about a year old and am wondering how you find the closed loop system to be working? lately, I'm working with a lot of two-sided routing which has been exposing the backlash faults of my machine. These faults are pretty minor and I feel that given the overall size of my router (60"x120") it's almost not worth mentioning. In my case, a closed loop driver would, I believe, have no effect on my cutting since the effect I'm seeing is outside the loop. On the other hand, if I had a linear scale on the axis's I should get pretty exact cutting since the scale would place the backlash inside the loop. Just wondering if your drivers are living up to expectations.
I'm 100% impressed with my closed loop steppers. I've purchased similar technology from two different distributors and they are both great. No regrets and way fewer headaches. They work great.
Hi, how much Nm for stepper motor for xy axis for lathe?
i ve bought a nema 34 closed loop kit and have the same driver . When i powered it up with 60Vac current from a 600VA transformer it was just plain dead. It flushes current throw the A+ A- B+B- and does not not give Green or Red light . The 60v ac is the recomended power but it does not seem to work. Most of the sites however selling this driver , are also salling a 48 V dc 400w power source. When you first powered it up
i trashed the proble; it was a malfactionning brige ac dc GBJ 1010 . However i had to upen it up . Very poor job
I also had to do a lot of new weldings rebuilt the heat shields
also i would suggest a lot of modiffying on the drivers built in power bridge as it is a real mesh
sorry for my spelling i am rather nervoys and cant hold my self .
Hi. I recently had issues with my NEMA 34 12Nm motor/drive malfunctioning. I was using a 60V 400W switching power supply. I changed over to a 48V 500W switching power supply and everything seems to be working better now.
actually the driver power circuit uses an ntc 14d 301k and a glass fuse of only 5 A . That means you actually cant power it over 400 watt i thing . You should also check the bearings as they seem to be the basic nema 34 . the transformer they recomend is 300VA so they recomend to power it with just 240-260 watt taking into account their ac dc power circuit board. If you had opened up the driver , you would have seen the transistors beneath the board that power the motor widings. Mine were poorly solidered. I suppose you have wirred the pending and the alarm signal to your control board.
Did you have these for use with the Acorn?
Yes. I''m using them on a PM25MV milling machine and driving them with the Acorn: th-cam.com/video/fVnHqQlyLnQ/w-d-xo.html
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
Hi. The RS232 cable is only used to program the drive. It is not used to interface with the breakout board.
Is programming the driver with the RS 232 cable necessary to obtain accurate measurements while the CNC machine is running or is it sufficient to adjust the settings in the Mash3 program with the hardware? Please clarify because I always work with only stepper motors without encoder, thank you very much

Hello. Download the driver utility from the Dropbox location and use the test routine to see if you can make the motor rotate. Then you can eliminate the motor and driver as your problem.
Bought a set of 3 x Nema 34 Motors Nm12 and 3 x HBS86H and 3x Power Supply 350W 60V and 1 x Breakout Board Db25-1205... 6 Axis for Mach 3. When wired everything I could only bring the z axis to move under Mach3 the x and y didn't move. But if I wire the x to. Pin 6+7 of the z axis at the breakout board then x moved very good and the same with y... Always what's wired to i 6+7 at the breakout board works good the rest not. So I must look is the board broken or does the software not work as it should???
It is possible that you have a bad Break Out Board. I've seen that happen before.
@@FrancoCNC that's what I thought first so I ordered one it comes in two days and also get a new from the seller. So I get two new ones and hope one will be okay 😁✌️👍at last.... my second thought was the idea of a friend that the optocuppler doesn't catch the too fast pulses and should be slowed down and that z is slowed down by factory default.. .. But I didn't find one proof for that theory z is on every menu set the same as x and y. At how many steps did you set your pins at the case of the motor driver 400 is default i think about 1600 to 3200 is best my Nema 34 have 12Nm and are really big and strong for the Optimum Bf16 Mill it's like a mini mill from Sieg 550W is the Spindel motor. The next step after I'm used to the 3 axis a little is building the 4th and 5th also with the same motors and the rest steel 😁✌️
I like your channel keep on doing the good work 👍😎
Ah the enable I didn't wire cause my wiring plan says you don't need until you use them and that will be later with Spindel and coolant control then I have to wire enable...
Do you know what does it mean when it blinks 9x?
I have an HBS860H with a 86HBS85 stepper and a 60V power supply. I can use up to 25600 pulse/rev but not 51200. Any ideas on how can I make it work 51200 pulse/rev? Thanks.
It could be that your pulses are too short for the driver to read. I believe you need pulses to be 10 micro seconds in duration.
Franco, do you still like these drivers?
what ac voltage can you run them drivers?
He said it at 05:20. 22-70V AC or 32-100V DC
can i drive the motor directly with the driver without connecting the rs232 cable ?
bcz im not able to drive the motor with just the driver and dc 48v supply
Negative. You need to send step and direction signals to the input terminals.
@@FrancoCNC Can you drive the motor with the dc power, driver, and a rotary encoder?
@@dpavlovsky I use a switching DC power supply. The motors have the encoder built into them.
@@FrancoCNC Yeah, I just got one of these HSS86 w/ a motor. Came with a serial cable that you hook up to the motor, and then hook the other end (6 wires) into the encoder terminals of the driver.
Also, have you ever used this: www.aneramall.com/index.php?main_page=product_info&products_id=2812
Yes. There's a little confusion here about rs232 cable, serial cable etc. You don't need the rs232 cable to drive the motor - it's just for tuning. You send step and direction signals to the driver's input terminals using individual wires connected to your breakout board/motion control board. The driver and motor are connected to each other with 2 cables - a 4-wire cable to drive the motor, and a 6-wire cable to read the encoder signals. The 6-wire cable comes out of the motor with a 9-pin D-sub connector on it, which is often used for rs232 standard, but in this case is nothing to do with the rs232 port - it's not a serial cable, it just looks like one. If you want to get the software and tune the motor, you need an rs232 cable with a 9-pin D-sub connector on one end, and what looks like an ethernet connector on the other but is, I think, a 6-pin RJ-25 connector (see en.wikipedia.org/wiki/Modular_connector). Hope that helps.
Hello, can you hepl me with RS232 debugging sw and cable? I am not able to comunicate with driver. Thank you.
Hello,
Can we use servo motors with the duet board?
Thanks
Hi. You can used closed loop steppers on any board that can send step and direction signals. So, anywhere a standard stepper can be used, you can use a closed loop stepper and get MUCH better performance. If you are shopping, be sure to check these guys out: www.omc-stepperonline.com//?tracking=5e66c8d3ae793
If you decide to make a purchase, it will help support my channel. Thanks!
@@FrancoCNC ok thanks
Franco, it’s really hard for me to find info.... I bought the toroidal transformer 220v ac in 60v ac out 900w for nema 34 12nm steppers my question is..... These transformers cause a influx of power at startup, they say to use a thermistor but WHAT SIZE? Do you need a Capacitor? ( reason I bring this up is my breaker trips every 1 out of 4 times)
oh man, and You working with cnc, ;(
Ruuge uuge my apologies CNC GOD!! I bow to you!! You know I have learned all my machining skills by asking questions. I saw this channel and thought I can do that! Which I have now accomplished! I didn’t need a capacitor or a thermistor. I talked to a very nice gentleman and he told me what he uses. Which was a YC-10-2D with 6" Din Rail and 2 Screws Yuco Miniature Circuit Breaker D Curve 277/480VAC 115/220VDC (2 Pole, 10 Amp) my set up now works! I’m a electrician that works on fighter jets not a fucking idiot. Tell me Cnc god what would you use?
Could you use that driver with a standard stepper and a linear encoder ?
Maybe. It sounds like you have something special in mind. I like the FastToBuy stuff but I can tell you that if you need tech support, you may be better off dealing with a company where the language barrier isn't as big a challenge. But, you'll pay more money for that.
+Franco
I got a PM-30MV and I am debating how to CNC it. I noticed one of the greman machines where I work uses a linear encoder for servo feedback, like you would find on a DRO for a manual machine. This stragety seems briliant to me because any backlash is taken out of the equation. Even a high precision servo is only as good as the mechanical system that it is attached to.
FML I miss spelled German
True. You may be able to find a way to use linear encoders - that would be cool. My thoughts are this: try to minimize physical backlash and use standard encoders/motors/drivers. I'm working on a kit for this machine that has double nuts for X and Y which will be adjustable with set screws. You'll be able to add as much pre-load as you like on the ball nuts to take out the back lash. But...there will always be some back lash due to clearance in the slide ways and torque windup in the couplings. That being said, I'm pretty sure we'll be able to get under .0015" on X and Y. Maybe even less than .001" depending on how tight the ways are.
+Franco
I am stoked about this, what do you have in the way of kits ?
I bought mine on aliexpress they supplied English documentation
Nice video I just bought 4 HBS86H WITH 86HSM85-E1 MOTOR of this the 8nm motor my problem is how to know the step per revolution of this motor for computing the step per unit to put on my cnc software. because I saw in es-m23480 datasheet that it's 3000 rpm and 2000 rpm I don't know if this is the step per revolution of this motor.
Hi, I consulted you and I solved the issue of revolutions? thanks greetings
The benefit of using AC instead of DC.
Switch Mode Power Supplies produce DC power and are cheap because they dont use lots of copper and are easy to manufacture, but fail easy.
Transformers are Solid and weigh a lot due to the copper windings and the ferrite or steal core, the quality is based on the winding insulation laquer etc.
Using AC you do not need any rectifiers or power conditioning/filtering just feed the AC power to the Driver, the downfall is the transformer will not fail when power surge spike occures and can over voltage the driver causing it to fail. The DC swichmode power supply is the failing component, and its cheap to replace.
With the transformer the price will be higher due to the weight and freight..
great video! can i control this driver with arduino?
Sure. You can control it with any device that can output step and direction pulses.
@@FrancoCNC excellent thanks!
I'm late to the game, but thanks!
How long did it take to get these from them?
I've ordered several different times. It never took more than two weeks.
Franco have you ordered from these guys they include power supply’s but from what I can tell no cables.

Never mind on my questions I ended up ordering the nema 34 12nm from fast to buy. I figured I’d stay with what you have and that’ll help me hook it up. Thanks for your time sir!
Thank you for the docs on your dropbox

Hello, try to connect by means of an FT232RL the wiring of the RJ11 connector on the page of this manual is different than the one attached by Mr. Franco
A switch mode power supply is more efficient than just a transformer.
Have you figured out how closed loops steppers work yet?
Yes. What would you like to know?
No I am good, I have an undergrad in Electrical Engineering and an Associates in Industrial controls and Robotics, you seemed really confused regarding holding currents with closed loop steppers and I wanted to make sure you figured it out. Thanks for offering.
@@mrkattm I am often confused. Please don't hesitate to write comments that will help people learn. Thanks!
I don't know driver programming.....
I know only dip switch setting , only dip switch setting this motor & driver working'ah? & Sorry for my bad English , pls reply me dude
Buy from these people - no software required. All settings with switches. www.omc-stepperonline.com//?tracking=5e66c8d3ae793
I m only doing dip switch setting its work , r u right????
i have tried to make own communication cable in rs232 side pin no 2 is connect to pin no 3 of rj11, pin no 3 of rs232 is connected to pin no 5, pin no 4 of rs232 is connected to pin no 2 with diode and 1k resistor, pin no 5 of rs232 is connected to pin no 4 of rj11. still im not able to connect driver to software plz tell me the right connections
bundling the powersuply doesnt say a lot , could be the seller just has a cheap shipment of sumting that "works" that he wants to get rid of
i wanted one power supply to power all the steppers in my setup , nostly to keep the size of the box down and theres a complex calculation to find out wat you need :
www.cnc4everyone.com/electronics/power-supplies/
i whent for the golden middle way in volts and for maximum in amps to have enough headroom and not overload the motors or the power supply
as for the manual : if you look at youtube for the chineese leadshine closed loop stuff the leadshine fabricator is actually putting the american type number in there comments below as they get this question about the manual several times per hour and if you search with that typenumber you get the american website with the proper online manual
hadnt seen the option about programming the drivers through software (not quite that far intoo the build yet just purchasing goods)
just in case youre building a complete unit : i found a realy nice ethernet controllboard/bob that doesnt get squirily when therers electric interference nearby and works realy well on both uccnc and mach3
www.cncroom.com/interface-cards/uc300eth-ub1?language=en
going to buy this myself as well , going to run the cheaper uccnc software
looking back its a good thing i waited with the purchase of the controller a while as the other versions running the same ethernet board needs a seperate break out board to hook it up to all the stepperdrivers spindle and analog stuff
Check out the Centroid Acorn software/control board package. What they are offering blows everything else out of the water.
going to look intoo it , havent seen any youtube how to's on that program , the most used one seems to be mach and uccnc
The Centroid Acorn is just hitting the market. I bought one and I'm very impressed. Very professional. Way less "fiddle factor" than Mach3 or Mach4. The software and the hardware come from Centroid and are perfectly integrated. I plan on making some videos as soon as I can get past this hurricane Irma thing...
The Acorn is new, Centroid has been around a long time building CNC controllers for real machine tools. Centroid Acorn is what I am using for my Lathe conversion.
Nice! I plan on using Centroid on my lathes, as well.
