CNC Standalone controller Wiring and Operation Demonstration

[@PatrickHoodDaniel]

Thank you all for taking the time to watch this video. I am truly grateful and hopefully you get some use out of it. I mention this in the description, but it is important to not here: If you are considering purchasing this controller, there are different versions and each one has critical differences. Go to the product page (link just above) to see the different versions and the differences.

Am I correct that with this standalone controller you can use a CNC milling machine both in proper CNC mode i.e. by converting a CAD file to G-code and milling out an object accordingly, but that it will also allow you to use a CNC milling machine as an electronically controlled manual milling machine i.e. instead of turning turning the crosstable wheels you just tell it to move the x-axis 40 mm to the left, the y-axis 200 mm forward, and the z-axis 15 mm down etc?

[@PatrickHoodDaniel]

This controller will process g-code in the traditional sense. If you take your CAD geometry and apply machining operations to that geometry to form g-code, you can save that g-code to a thumb drive and process it on this device (move the machine according to the g-code). You can also use this control as you would any other controller and move it manually. I would not suggest cutting with the pendant unless you have the correct feedrate parameters built into the parameters. The pendant is chiefly used as a way to jog to desired positions and stop the machine if needed.

[@Brute4rce1111]

Do you know how to change the startup boot menu logo on it?

[@PatrickHoodDaniel]

No, I haven't delved that deep into the unit.

[@pierregauthier3077]

I've had this controler for 4 years now. It works well most of the time. My issues are that only G54 works for positioning. The H and D offsetting does not work. Another thing is, if too many files are on the usb, the control won't read the USB.

[@PatrickHoodDaniel]

Excellent information. Thank you so much for this! Do you have the 3.1 or 4.1?

[@pierregauthier3077]

I have the 3.1​@@PatrickHoodDaniel

[@pierregauthier3077]

Another thing is. Once you have your machine ready to cut. Cut some squares and circles. Physically measure them, then adjust the numer of pulses in the control for each axis so it cuts on size.

[@PatrickHoodDaniel]

@@pierregauthier3077 The formula that I added in the video is a first step. You can adjust as you mentioned if the calibration isn't quite perfect, but don't let runout or incorrectly sized tools cause a change in the steps per unit.

[@pierregauthier3077]

​@PatrickHoodDaniel you are correct. My power supply is variable to 36v. I can't explain it but, if I change the power output of the power supply. My cutting sizes change. I have open loop steppers.. but a step is a step regardless of power supplied? I do have closed loop steppers waiting for me to swap them. I'm currently using 1 power supply for all the steppers. Sould I used individual ones? I've learned so much building this. Seems like the more I learne, the more questions I have 😂😂😂😂

[@sifsif7809]

Hi, Would you recommend this controller or any of the newer versions from nema 34 12.5nm closed loop motors, for 3d carving for long hours and gcodes more than 3million lines? If there is a step loss, would the process stop and show an alarm? Would those controllers run the machine at high feeds and acceleration like 12.000mm/min and 500mm/sec2? If there is a stop of the process, will there be a way to start again from the line I want? Thanks for your time, I'm interested into buying this.

[@PatrickHoodDaniel]

Those are all great questions, but I haven't tested this controller extensively, so I would not be able to tell you, but those speeds look withing the specification.

[@homeshopmachinist84]

im confused on how to setup, my stepper driver is set to 800ppr and i have 1605 ball screws so each revolution results in 5mm of travel, what would i set the ddcsv to?

[@CraigHollabaugh]

Great editing on this video. No fluff.

[@PatrickHoodDaniel]

Thanks!

[@chanchalsakarde2768]

how to control steps movements, like lets say we have 400 circular points to move one by one and i need to move pointer in following example sequence starting from 0->10->240->45->28-> .......... -> 400 . How can we automate this ..

[@PatrickHoodDaniel]

Not sure I understand the question. Do you want to make it so the number of steps, like 20 steps are delivered, then 240 steps are delivered and so on? This can be done using gcode, but you will need to set the steps per unit accordingly.

[@new2diving]

I see the backlash compensation parameters but are there any parameters for ball screw error mapping ?

[@PatrickHoodDaniel]

Now sure. I haven't deep enough into the settings. This controller is the cheaper one on the market. There are others, like the expert and the 4.1 that may have these features.

[@ShawnHawkins666-33]

Im building a cnc wood router, a MPCNC and had the Jackpot control board in mind. Will this replace that? I own a few 3d printers but this is my first foray into the CNC world.

[@PatrickHoodDaniel]

@@ShawnHawkins666-33 I am unfamiliar with the jackpot control board. I do a Livestream everyday at 1:00 Eastern. I can delve into this on the Livestream if you like.

[@ShawnHawkins666-33]

@PatrickHoodDaniel that would be awesome. I'll see you then.

[@sputnik9708]

Looking to use a controller to run a simple cnc back gauge and some limit switches for a press brake. Like the options of the v4.1. Are you able to write basic gcode straight from the machine? I don't need any spindle controls. Just move xyz steppers then machine pause, and more movement. So far this looks like a really good option!

[@PatrickHoodDaniel]

The only way to get code into this controller is to use the thumb drive included. The controller doesn't have an MDI feature.

[@sputnik9708]

@@PatrickHoodDaniel thanks for the reply. Are you able to edit existing gcode?

[@PatrickHoodDaniel]

@@sputnik9708 Just like any gcode, you can use a text editor and modify the code. Or you can modify the machining operations in CAM and re-save the g-code. Editing the gcode in the controller is not possible as far as I know..

[@sputnik9708]

@@PatrickHoodDaniel copy that. I see the "expert" controller offers the ability to write and edit gcode, wasn't sure if that was carried over to this one. The manual for the v4.1 says options for creating a new file and editing a file, but doesn't go into detail on those processes.

[@PatrickHoodDaniel]

@@sputnik9708 That is good to know! Thanks you. IU'm guessing it would be quite cumbersome without the M3K keyboard (amzn.to/3vvLXuD).

[@ibrahimkaratas6088]

How does it continue where it left off when the power goes out?

[@PatrickHoodDaniel]

I have not tested it in this condition.

[@gregoryjohnson3627]

why does this thing call for using 2 separate 24v power supplies for the controller and the MPG? just used the same and it seemed to work. my MPG will move around the cursor while in the menu, but it wont switch to mpg mode and let me jog.

[@PatrickHoodDaniel]

That is a good question. I thought I mentioned something in the video about this, but if I didn't you can use a single power supply and just jump the terminals. I did this in my testing. Even if they are prescribing a separate supply for different functions, it would not make any difference.

[@oldschoolgaming6135]

Hello. Can you use this for plasma cutting operations? Thanks a lot.

[@PatrickHoodDaniel]

@@oldschoolgaming6135 I don't think it would work if you plan on using a THC (torch height controller). You would need to resolve the torch distance to the plate mechanically.

[@oldschoolgaming6135]

@@PatrickHoodDaniel Thank you so much!

[@naterowley8503]

Do you know if this controller will work with closed loop stepper drivers. I assume the encoder is all delt with in the driver but would like to ask someone to be sure.

[@PatrickHoodDaniel]

Yes, it does. I just built a system that has closed-loop steppers on this controller.

[@badmintonmaniax4864]

What the post processor used for this controller in CAM software?

[@PatrickHoodDaniel]

I put a link in the description where I found the most information on what post processor to use.

[@sasasasa711]

Can this be used for all types of wood carvinf 3 axis operation? and the post processor?

[@PatrickHoodDaniel]

I added a section in the description that talks about the post processor after doing some research. Yes, this controller can do 3 axis carving.

[@IceCreams62]

Hi. One curiosity. Why did you remove the keypad/screen protection sheet ??

[@PatrickHoodDaniel]

I like the look of the face without the plastic. Personal preference.

[@povilasvaiciulis7931]

is there a way of making it ATC ?

[@PatrickHoodDaniel]

Not that I know of. The outputs are limited. You would need outputs t to control relays to control solenoid valves to release and accept tools.

[@metalsliver4325]

Can you use servo motors ?

[@PatrickHoodDaniel]

Yes, I did a build recently with servos, but the servo drivers need to have step and direction terminals.

[@SILVERBULLETSS86]

Question, would you recommend this over mach 4?

[@PatrickHoodDaniel]

No. There are too many features that Mach4 has that this device would not be able to do. To name one of many is the number of outputs available. Mach4 can be interfaced with very complex and unique setups and each setup can have its own profile. This also goes for Mach3. For instance, If you have a machine that features multiple heads (spindle, laser, plasma, additive nozzle, etc) on the same machine, mach4 would be able to be adapted to each very easily with a switch to one of the profiles, or be adapted to use multiple at the same time. MAch4 can also be adapted for unique robotic applications along with the various controllers that use Mach4. Another top of mind is probing for measuring surfaces, or finding position for fixturing. Mach3 and 4 would do this with ease where the DDCS controller would be a one trick pony. I do recommend this controller for those that are looking to do only a single application and has a relatively simple setup.

I've had and been using this contoler for 3 years. Only G54 is usable even tho G55, G56...... show as being available. The height and diameter offsets have the same story. As a machinist, this controller is not perfect but serves the purpose well when it comes to basic 3 axis function.

I don’t know how to use g configurations, I wish to know that

I'm planning used dm500 stand-alone on my machine .please if you have any knowledge about micro programming in these controller share with us

[@GrimResistance]

Nice video, probably gonna get one for my cheap hobby mill. Consider adjusting the audio towards the end though, that beeping was driving me crazy!

[@PatrickHoodDaniel]

Thanks, will do!

[@decootubization]

Q: can it be used to control 3D printers?

[@PatrickHoodDaniel]

Probably not. Accepts g-code and has outputs to control devices for extruder, heat bed, etc. However, It wouldn't be able to perform some of the complex tasks like bed leveling that is present on most modern 3D printers.

[@myname3463]

3D Printer Kit with RAMPS 1.4 works like a charm whit Marlin Firmware

[@PatrickHoodDaniel]

@@myname3463 Yes, that would be a much better platform.

[@dd_Dedsec]

Remember if the motor is rated of 5a phase current or rms.. The current you need to set on its driver will be √2 x 5a = 1.414 x 5 = 7a! not 5a

[@PatrickHoodDaniel]

Thanks

[@tonyn9632]

Hello, Do I need March3 to work with this controller Sir?

[@PatrickHoodDaniel]

No, this controller works all by itself. It's a standalone controller. No computer or CNC software needed. If you have a slave axis, then you will need the DDCS 4.1 variant.

[@SomeTechGuy666]

I love what you are doing but I wish your devices had open source code. And I wish the display was larger.

[@PatrickHoodDaniel]

I agree, but for the price these are retailing, it's a good option to free up a computer. All open-source control will typically require the use of a computer. The source of this device is firmware and would be challenging for a typical hobbyist.

[@wolleausmallo1]

I reduced the speed to 0,75.

[@KarlMiller]

@1:10 you mention that you are using a ONE AMP power supply "for this quick test" - why make it purposefully more confusing? Nobody will use a one-amp power supply to drive a CNC, so all this did was confuse people. The rest of the content does not work as instruction because you commonly share details in a fast-spoken speed such as "let's go with 3200" without explaining why you are choosing these random number values or how to make the correct decisions for these parameters for the viewer's own equipment relative to this controller. The only thing useful about this video was that it introduced this controller exists.

[@PatrickHoodDaniel]

The one amp power supply is only for the power for the controller, not for the motor power. Did you see the section at 7:00? Also, at the 5:00 timestamp, I show how to adjust the values to work with a custom application (calibrating each axis).

[@pierregauthier3077]

So to properly shelid ypur wires, you ground them to the cabinet the ground the cabinet to the earth?

[@PatrickHoodDaniel]

@@pierregauthier3077 Two options, ground to the cabinet which is earth grounded, or ground to digital ground.

[@tcurdt]

Wow - that's an absurd price. At least for people that don't mind to tinker.

[@PatrickHoodDaniel]

I don't think the price is high. If you consider the alternative (other than RPi) as a dedicated system, you would need a computer, a CNC controller, and CNC control software. Is there a standalone option that you know of that is less expensive? If so, I would love to get my hands on it and review it.

[@tcurdt]

​@@PatrickHoodDaniel IMO the only distinguishing factor is the "stand alone" really. For that kind of money you could get a bigger screen, a pc with even a mesa. Or get a cheaper controller and pendant. There certainly are options. The only benefit I see is "no tinkering" and the "stand alone". But priorities vary.

[@PatrickHoodDaniel]

@@tcurdt The DDCS v3.1 is $250. I haven't seen a PC, monitor, controller (even Mesa) altogether lower than $250. Are you referring to a used PC with a parallel port?

[@tcurdt]

@@PatrickHoodDaniel The DDCS v4 seems to be around $400+ (for me). A good enough used PC (without a parallel port) you can get for 30 bucks, screen you can spend more, but less than 100 is easily doable. Plus a new mesa for about 150. Or alternatively with a NVEM with remora for about 80. Or one of the better grbl(hal) boards for about 80 (if you are not keen on linuxcnc). There are options. 400 bucks for a DDCS just doesn't feel right - to me.

[@PatrickHoodDaniel]

@@tcurdt Sure, getting a PC for $30 will do it and keep it out of the landfill, but I would not go as far as saying that this standalone unit is "an absurd price". The DDCS v3.1 is $250 and a good option if you don't need to slave an axis. I believe this standalone CNC controller is a very good option for those not wanting a complex arrangement of computer, controller and software for an excellent price. Most CNC programmers would want a much more sophisticated system like the Masso, which is $1200+. One price may be attractive to one person and not another. I would like to keep this discussion going. You are providing an interesting perspective and this discussion can "work out" a lot of details.
