@@RayMAKES Ray, I believe you'll be very pleased with Centroid Acorn. Centroid continues to improved the hardware and software.

@@martyscncgarage5275 I'm actually retrofitting an old plasmacam table. I wonder if the conversational aspect of cnc12 would be easy enough for my guys to use to make flanges and cover plates

Yes you could, but you'll need to make sure you have or fit up 5vdc differential encoders to them

Not the proper way to reverse the direction. The encoder and motor rotation need to be synchronized. Otherwise you can have a run away condition. The motor is turning one direction by the encoder reports it's turning the wrong way, so the controller tries to force the servo into position, which it can't do. Until it faults. So, it's not as easy as just swapping motor power leads

Not likely. I would suggest you call Centroid. You'll need a spindle drive that accepts +/- 0-10vdc analog input

​@@martyscncgarage5275 So what to do when the AC/DC Drives only control 3 axes X, Y, Z. Do you have a way to control the main axis?

​@@noithugian494I don't follow. Please go to the Centroid CNC Users Forum and post pictures of your machine, axis motors, axis drives, spindle motor, spindle drive and pictures of their nameplates. We can help better with more information centroidcncforum.com/

Yes. Very common to use one NC home switch per axis and to put them in series and use ONE input on Acorn. Program the input HomeAll

@martyscncgarage5275 Hello, Marty, Im not talking about the goming switches. I was talking about the hard limit switches in case the servos run away. I have one limit switches per axis and two trip blocks on both ends of the table. That's the way Anilam did their CNC that I'm retrofitting with Acorn. I think I might have a solution, I'm thinking of running parallel wires from one contact to for both axis limits.

@@trikepedaler there are limit inputs. Did you buy Ether1616 so you have more inputs? Memory serves there is also a LimitAll input that works like HomeAll

@martyscncgarage5275 Thanks again, I watched your limit and home switch video on UA-cam . Thanks again.

I don't recommend using an AC servo for a spindle motor. I have not had good luck getting them tuned. They are really not designed for spindles. Feel free to reach out to DMM for further advice.

I would try and stick with a 3 phase motor and VFD with a braking resistor for the spindle. I got lucky and was able to mount a differential 5vdc encoder on the other end. I would go with Clearpath SDSK servos on all axis. Be sure to get one with a brake for the Z axis if necessary

Go to the Centroid Users Forum and post the details.

No. The braking resistor is part of the VFD and not all VFDs support them.

Should be ok. Give it a try

You're asking something that's years old. Unsure what you are referring to. The machine is still being used currently.

Great to hear!

The Emcoturn 120 has long been done. It used 4 sensor gray logic. It would be very helpful if you found a schematic for your turret/machine

Not enough information? New build? Existing control? Please post your question with more details along with a fresh report. F7 Utilities, F7 Create Report centroidcncforum.com/viewforum.php?f=20

Use and assign an unused input. You will also need the detect to let the control know you have the KP3 connected. Those would be the two inputs. You have a third wire that needs to be wired to COM Please post to the Centroid User Forum. Post picture of your cable you received with KP-3 centroidcncforum.com/viewforum.php?f=60

Look at Clearpath SDSK servos, also Leadshine AC servos. Go to the Centroid User forums, post pictures of your machines and folks will provide suggestions as well

The drive logic for step direction signals comes from Acorn, it's passed through C86. Some signals are monitored by C86. You still need an appropriate motor power supply

Well, they are out there. Watch Craigslist, FB marketplace, even eBay. Problem is, like this one, control is dead and needs an upgrade with many of them. Good. Luck!

You might also look at Precision Matthews mills. If you want to do a CNC conversion, look at Grizzly G0704 and convert it. Google G0704 CNC and you'll find a lot of info. Syil also makes CNC machines us.syil.com/

@martyscncgarage5275 Hi Marty so I went ahead and bought one of these it was bran new from a guy on OfferUp. I’ve got it all setup and running great with LinuxCNC but my only problem is I don't understand how to get the spinal working through software. I’m able to run M3 S1000 and M4 S1000 and on the display panel of the machine indicates the direction is changing from forward and reverse but the spindle does not turn on. Is there some sort of PWM settings I’m also supposed to be configuring? If so, I don’t understand it and my guess is that I’m supposed to configure PWM on either pin 3 or pin 9 because in the user manual it says those are signal pins of some kind. I did try it once and after turning the spindle on through LinuxCNC the back of the main power panel made a horrible noise like a relay freaking out and immediately pulled the plug. Hope I didn’t damage anything. But can you give me any advice on what I should do? There's no information about configuring the spindle online and Syil won’t respond to my messages. You seem to be extremely knowledgeable on all this. Thanks?

@@DaveNorthWest I'm sorry I know nothing about Linux CNC and it's hardware.

@@martyscncgarage5275 do you know if the stock Syil X4 spindle uses PWM or PDM to control the speeds? Sorry if I'm asking so many questions. Just haven't gotten to get an acorn system upgrade yet

Change the frequency settings to 50hz and try that. You should be really contacting HY Electrical for support.

Friend of mine

It's older but to some extent still applies. In any case I'm glad you found it useful!

No sir. I sold all the original parts. You can still buy them.

@@martyscncgarage5275 please tell me where. Fadal tells me they are discontinued. And thank you for your time.

​@@markneary874 sorry to hear that. There are several dealers of Fadal products. I assumed you googled them and tried them all? I guess then there is eBay...

Download and follow the Centroid Acorn system schematic

There is a schematic for Acorn and the G540 showing the Estop wiring www.centroidcnc.com/centroid_diy/schematics/pbrowse.php

A little bit. Cnczone. Com has information in them.

Thanks I appreciate the comment. I'm doing some personal projects right now, I'm not getting any younger 😁.

@@martyscncgarage5275 i am glad you are alive and well

I am unaware of this. However, I am going to be setting up a Clearpath SDSK system up soon and if there is something new or different, I'll post an update video on that subject

You should post to the Centroid User Forum be sure to let everyone know what schematic you used and the excerpt from the manual you are quoting. Always post a fresh report as well. I have not been active because I've had some personal projects and they've only multiplied

Hi Marty, I added a post on the centroid forum as of today.@@martyscncgarage5275

@@avpriority just did basic bench test. Will be bench testing the Clearpath servos soon in between projects. Let me know what you learn and likewise I'll get back with you when I get to that point.

Hi Ronald. Not sure what you have. I can tell you that many people get overwhelmed with the conversion and or find they don't have the ability to wrap their mind around it and abandon the project. Others are too busy to do it and hire someone to get it done and back in service. They find it can be pricey, but if the machine is expensive, it can be put back into service and start making money again

With my old control I was going to try ridged tapping but control said this feature is not supported. There is no encoded on this spindle drive motor. Need to deactivate ridged tapping.@@martyscncgarage5275

@@martyscncgarage5275 I have 3 centroid people working on this issue ( spindle does not move )for 3 weeks now. There is 0.00 DC voltage at the ( H5 analog out ) spin-com / spin an pins and it should be 1.66 will it ever work. I payed $6,000 for the upgrade and I still have a $30,000 boat anchor.

If the DC brush servos are good, consider Centroid All in One DC. You will likely have to upgrade the encoders in them

Homing a machine sets the machine datum. You can create multiple work coordinates. What are you trying to accomplish?

Yes, preferred over a mechanical limit switch. Make sure it is NPN 24vdc NC

Try cnc4pc.com. call them

The machine belongs to a friend of mine. What specifically do you want to know?

I need the tool holders on the turret. Can you provide an e-mail or whatsapp number for communication?

Personally would not use anything else. Hardware and software from the same company who has specialized in CNC Motion control for well over 30 years. Constantly improving software.

@@martyscncgarage5275 that is how I felt. Glad you confirmed it. BTW I have been enjoying your other videos. Thanks for taking the time to make detailed videos. I'll be watching a lot of them. Also subscribed. Thanks

​​@@whistle3man​@whistle3man Thanks. Unfortunately Centroid has made so many improvements to their software and hardware, the videos became somewhat obsolete. But that IS a testament to Centroids commitment to improvements. All their boards are true motion controllers and now they have a solution for just about every project. You just need a good machine and the skills to execute the conversion.

​@@whistle3manTheir user forums are a great resource. You should check out their success stories to see what others have done if you haven't already. centroidcncforum.com/

@@martyscncgarage5275 thanks. No problem on the machine end. I spent over 40 years in machining with the last 27 designing machining assembling and testing large research equipment for a large aluminum company.

Sorry, no

We use it as a servo fault to stop the CNC control.

Not following. You want to convert a 3phase CNC machine to single phase and Centroid?

@@martyscncgarage5275 yes, our machine is a multicam 2000 laser . It uses 3 phase power, our thoughts were to convert to a single phase, replace motors and obviously the power supplies. We aren't sure yet if it's too daunting but there are lots of issues keeping it how it is.

@@laserfalcon if your laser power supply is three phase you'll need to keep that. Since it's a laser table, I doubt the axis motors are that large. If I were you, I would take pictures of the machine, machine label, control cabinet, axis drive labels and post to the Centroid Users forum. centroidcncforum.com/ Ask for suggestions. You WILL get good advice. Mention if you have schematics or not or can get them for your machine. Also mention where you are located. Let me know when you do

Variable Frequency Drive. Controls the speed of the spindle motor

Make sure you only ground the shield at the Acorn end and only to one common ground point.

Absolutely! It's how you configure the software. Centroid also has an installation manual and many schematics

First did you download the Acorn Installation manual ? It's explained there. Use the Centroid CNC Users forum. Post a fresh report and ask your question there. But it IS explained in the installation manual which can be found on Centroids website

Yes, Teknic makes the Clearpath SDSK servos

​@@martyscncgarage5275 Wanting to switch over to centroid on a multicam cam 2000 laser cutter, using as much as i can, they use teknic drives and servos but this is all new to me but think i can manage if taking step at a time

@@laserfalcon you need to identify which Teknic clear path motors and drives you have and how they are controlled first. Especially if you plan on using Centroid Acorn. They must be able to take step and direction signals. I suggest you get the drive and axis motor model/serial numbers and give Teknic a call and ask to talk to an Applications Engineer. They are most helpful

@@martyscncgarage5275 Thanks for that advice

What format laser?

@@MartyEscarcega pwm i believe

@@laserfalcon is this a small bench top machine? Acorn fully supports PWM and I have driven a laser with it mounted on my router

@@laserfalcon have you done a UA-cam search for Centroid CNC Laser?

@@MartyEscarcega i was in touch with centroid but not done a search yet

The software used to require a reset on power up. Are you saying that feature is missing? Please run over to the Centroid CNC User's forum and post a fresh report there with your concern. Centroid will comment on it. If you hit Estop and reset E-Stop, you reset CNC12
