Hello Marti
first please excuse my bad english.
I am from Germany and my English was learned at school and that was 15 years ago.
I want to say a biiiiiiigggggg thank you to them for their videos.
I've been watching your channel for a while, what I really liked were the Emco conversions.
I also converted a Compact 5 myself.
But I removed the control from the box and screwed the machine onto the back.
This gave me a slantbed lathe.I then gave her a 750W servo as a spindle.
What a cute little toy she was then.
laugh
I have made a mistake.I watched you for 4 years and didn't understand what great software and Hardware you use.
It seems that a lot of people don't get that the Centroid and especially the Acorn Board is exactly what people need.
Also I was so stupid for a long time and tried to program with Mach3 Mach4 but that was a waste of time.
Then I played with Linux waste of time.
Mach 3/4 is rubbish in my opinion.Linux is a bit better that you can use process-safe to make coffee.
Centroid I think is the best.
You made great videos more than 4 years ago and only a few understand it.
Normally you should have 20,000 subscribers in my view.
Thanks again
I've also had an acorn at home for a month.
I connected it to an Emco Maximat Standard.laugh
Of course I'm enthusiastic about it.
Somehow you helped me to connect it.
I wish you all the best and stay healthy.
Greetings Stephan
Thank you for the kind words. I'm glad they helped. Mach 3 an d Linux helped start the DIY CNC movement. We'd likely not be where we are at today without them.
I agree with you on Centroid. The fact that Centroid has specialized in CNC motion control for over 30 years, designs their own hardware and software is what makes them unique in the industry. The also continue to invest and improve the hardware and software.
Marty your the man, i'm new at this and your video saved my butt for sure. I'm converting an old 1938 atlas lathe to acorn cnc..i bought stepperonline closed loop nema 24's 601 inch ozs with cl57t drives. No way would they work with the wiring shematic with them..but i watched your video and said what the hell I'll wire them exactly as you did with the kl5080h..and what do you know..they work awesome..can't thank you enough for your knowledge man thanks a ton!!
Ps..I looked for hours for how to wire these drives..not one ounce of info did i find. thanks again for your video.
Glad it helped!
I always enjoy your willingness to share such knowledge the rest of us. I was wondering if you think the acorn update would work on an older horizontal boring mill with an Allen Bradley controller that is going out?
Thanks
Ben, while doable, it's hard to to know what to recommend without knowing your budget, and what make and model axis drives it has, what axis motors, what spindle drive and what HP the spindle motor. Acorn and Acorn 6 only put out step and direction signals.
Coming along nicely!
I have the "integrated" Easy Servo system from Leadshine for my Z axis Bridgeport drive. Same guts as these but the driver is piggy backed on the side of the motor - cuts down on encoder cables etc.
And I see there are now clones available on AliExpress for $100 or so. Search for "STATE OF THE ART hybrid closed loop". No idea how good they are but if they are anything like the genuine Leadshine parts, their performance will be pretty good.
do you have any videos about connecting open loop drivers to the acorn controller?/ turns out the wiring is about the same for leadshine drivers , so this video works just as well.,, is the fault " alarm " connection optional ? is it only for diagnostics ?
Hi Rob, lots! Go to the Centroid User forum and post info and pictures of what you are working with. Will help get you going!
Looks very similar to the more expensive (2x?) Leadshine ES-P32320, which comes with an ES-508 drive. When you get the cable, please post a bit of the software. I've written software for interfacing with the Leadshine Easy Servo drives and I wonder how similar these drives are. If you have the parts, the cables are easy to make. A Cisco programming cable works on the Leadshine drive, and I assume yours. I also cycle the power to reset the drive after a fault, but now I wonder why I don't reset it via the programming interface...
Kent, John at Automation Technologies tells me these motor/drive packages are made by Leadshine for Automation Technologies. Feel free to drop him an email to inquire.
Merry Christmas Mr. Marty!!!
And to you and your family as well Marco!
Hi Marty. Great video. I ordered these drives/motors as well as the 48V power supply you recommended. Question: There are multiple pieces of drive programming software available. Which one did you use to program the drives?
Franco this was a simple bench test. I did not need to program them. I used it out of the box as-is. I do have two more and another Dyna DM2400 I am going to set up with them. I'll do some videos on that. On the power supply, 48vdc may be a little high. Using the formula found on Geckodrive's website on stepper power supplies, it says to take the square root of the motors inductance which is 1.85, which gives you about 1.36 and multiply that by 32 which equals 43.5vdc. That said, Automationtechnologiesinc.com sells a 3 axis kit using a 48vdc 969w power supply. Geckodrive's power supply white paper seems to suggest that a motor only draws 2/3 of it's rating. However, these motors have 3 coils. So, if you do the math per the motor spec sheet , the motor is said to draw 5.8a multiply that by 48vdc, and you get 278.4w per motor. So multiply that by 3 motors and you get 835watts. I am not totally sure that the 2/3 rule would apply to this motor. www.geckodrive.com/support/step-motor-basics/power-supply-basics.html
thanks I was wondering how the 5v went to ground and I did not realize the Acron did that, over thinking again
Through the step and direction signals terminals on Acorn
@@martyscncgarage5275 yes I was over thinking it for sure, after watching your videos I am now ready to set my systeam up tomorrow..
I also have a set of servos, are they easy to connect to the Acorn?
@@adrianharrison5208 I don't know what you have. If you have any trouble, post on the Centroid Users forum: centroidcncforum.com/viewforum.php?f=60
Be sure to follow this post so we have an understanding of what you are working with: centroidcncforum.com/viewtopic.php?f=60&t=1043
Excellent Marty!
this wiring is the same for nema 34 close loop? I have 5 motor close loop sets from Automationtechnologies!
I’m switching all my machines to Centroid from Mach 3.
But i just started learning about Acorn and Centroid this week watching your videos.
You are doing this very well, thank you for your time helping others with this nice work Marty!!!
Marco. Thanks, yes should be the same. Double check your manual. Be sure to use the dual voltage power supply that provides 5vdc and 24vdc. Jameco.com sells Meanwell for about $12. Glad you found it helpful.

Marty,
I purchased a NEMA 23 Kit from Automation Technologies. It came with KL-5056 drivers, a C10 BOB from CNC4PC and a 5V power supply and a 36V power supply. Do you have any schematics or info on wiring to the Acorn board?
Download the Acorn schematic package and follow the Leadshine schematic. Use a DB 25 male breakout board. You do not need your C10 breakout board. Though it may work. I'd have to look at it up.
Okay, The Schematic package has two directories. One for Rev.2 and one for Rev.3. My software is Rev. 4.12. The Rev.2 directory has a Leadshine schematic and The Rev. 3 has 2 schematics. The one in Rev.2 seems to be the correct one. Have any of these changed for CNC12 Rev. 4.12?
Hi Marty. Nice video. I think I'm going to buy these drives and motors for a small lathe I'm working on (that requires 1/4" shafts). What power supply are you using to drive the motors? How many watts do you recommend per motor? Thanks.
Franco, I had just purchased one to do some testing. I purchased 2 more to put on another Dyna DM2400 mill I have. I plan to use at least a 600w 48vdc power supply for three axis.
Thanks Marty. I decided to order a 36V 350Watt PS for each driver. Probably a bit more than what's needed in terms of wattage but if it's worth doing, it's worth over doing, right?
Hey marty,
Really appreciate this video as it encouraged me to go the closed loop + acorn route. I’m using the Nema 34 version but have been told it’s exactly the same to hook up.
Quick question for you, I’ve been pouring over the 5080H wiring pdf that Centroid has available and they have the Step / Dir hooked up via breakout board using the parallel port. Is there any good reason for that? I was planning on doing it exactly as you did, that was a big part of the reason I went with Acorn is the ‘all-in-one’ nature of it, I just want to be sure I’m hooking it up the best way possible.
Secondly, they consider the Enable +/- to be optional, can you tell me what that does? Is there any reason I need it or can I carry on just fine without it? As I said, just trying to do it right the first time.
I really appreciate the help!
You should post to the Centroid user forum: centroidcncforum.com/viewforum.php?f=60&sid=1008a0d5475ff32c7362bf07761f9dcf
But in a nutshell, the DB25 is similar to the parallel port. It would be a little easier to connect using a DB25 male breakout board you can buy on Amazon. There is no enable on the DB25. Enable means that when the pin is toggled (high or low) depending on the manufacturer of the drive, it will ENABLE the drive. Most drives come default enabled. For small stepper motors this is generally not a problem. When the control faults, or Estop is pressed, it will DISABLE the drives so they are free.
martyscncgarage Appreciate the quick response, I did sign up to the forums last night but I figured I would wait to see if you responded here rather than double posting my question. Enable works exactly as I expected it would, I just wanted to check.
As for using the DB25 board, if the only real difference in function is the ease of wiring, I think I’ll continue to hook it up as you describe in the video, it’s really not all that complicated as far as I can tell.
Thanks again for your help!
Marty, what input do you use for another driver setup? Do I change anything in the Wizard?
Robert, you simply set them up for each axis in the Wizard
Thanks for the quick overview. Is the Enable signal not needed ?
It can be used. I just put it together quickly for another user
As it says in the wiring diagram for Leadshine driver, the enable signal must be inverted in Acorn setup. Now it works fine on my side. Thanks for your detailed videos.
What does the acorn do? It doesn't seem to include with the kits I saw online.
Acorn is a 4 axis CNC Motion Controller. www.centroidcnc.com/centroid_diy/acorn_cnc_controller.html
Hello can we have a link with a wiring diagram of the motor driver to the acorn rev4 centroid board
You can find all Acorn Schematics here: www.centroidcnc.com/centroid_diy/acorn_cnc_controller.html
Hey Marty
I got a lot out of this video. You state that Flt+ is connected to Input 5. How is Input 5 defined in the wizard? Thanks!! And keep the info coming
Drive Fault. Glad it helped!
@@martyscncgarage5275 Thank you!
Question Marty?
It is possible to mix it different motors drives to Acorn board?
Because I have a big 5 Kw.
Yaskawa servo pack
And DMM 750 Kw.
Wish I want to install in my Bridgeport VMC!
Hi Marco, yes, as long as they all take step and direction inputs, you can mix and match.
Marco, 5kw is a very large motor. Is that your spindle? Also do you have a tool changer? ATCs
Marco, is the 5kw motor/drive on your spindle? Do you have a tool changer? ATCs require more inputs and outputs than Acorn has. You might be better off with Oak motion controller. You should call Centroid with the make and model numbers of your drives to see what is the best option for you.
This motor is going to drive the Z axis for now.I going to use the Acorn board . Tool change will be manually until
I buy it the Oak BOB.
By the way, do you have the video for wiring the 25 dB breakout to DMM servo drives?
Thanks Marty for your dedication to helping users with this Centroid board!!!
Thanks
Hi Marty the ena+ and ena- is not used in acorn?
Yes it could be. I was doing a quickie video for another Centroid Acorn user so didn't go that far.
martyscncgarage thanks also were did you bought your multi voltage power supply? Thanks
JAMECO.COM they are Meanwell Power Supplies. Look for the RD35-B it has both the 24VDC and 5VDC output. (Jameco also sells on Ebay)
martyscncgarage thanks Marty
They always run good on the bench. Connect them to an axis and whoa missed steps? Can’t tune with acorn? Nope. Frankly servos are the only way to go with centroid if you want any decent performance or consider mach4 a better solution for steppers where you can spend hours dialing them in so they actually perform decent. My servo driven centeoid machines run like a dream. I’ve not ever been able to get steppers working properly unless you run them immensely slow where you may as well machine by hand.
No issues with steppers and Acorn. The trick even with Mach is choosing the right stepper motors for the machine, paying attention to inductance values, choosing the right voltage power supplies to run them. This trips everyone up. Geckodrive wrote a great paper on stepper motors.
Closed loop systems match the stepper to the drive, and tell you at what voltage to run them at. You still have to choose the right size motor, but being closed loop, they can be size about 20% smaller, because machines with open loop steppers have been sized 20-30% larger to accommodate a safety margin due to their open loop design.
Sure makes sense that’s why buying a packaged setup helps but a set of 1600oz servos on a bench mill shouldn’t be losing steps with a 70v toroidal power supply above 25ipm. Have any links to acorn running open loop steppers? I haven’t found one searching all of UA-cam and three of my 6 vertical machines I’ve had all ended up not running with steppers but as soon as I threw closed loop AC servos on a couple, bam! they run like a charm. Now when I ran Mach on those it ran fine. That said it’s not always the hardware is it? Sure they have a lot more to offer for tuning. Well centroid has none. It’s just a different game. By the way all my UA-cam searches for open loop steppers with acorn only showed bench test videos.
Glenn, my D&M4 mill and Dyna Myte DM2400 both ran open loop steppers with Geckodrive G540's. Accurate and no issues. When it comes to large machines, I do run AC Servos.
Closed loop hybrid "steppers" also work well.
Good information but there's no need for all the recaps. We can easily rewind if we want to see something again. I'm looking at some of these drives and motors for converting a mill so thanks for the info.
Sorry you had issue with it but so many others found it useful.
