Build Your Own CNC Controller Part3

This series is amazing. Genuinely want to thank you!

how much cost all equipment of the CNC Controller box

I'm intredsted ok

Hi i have nearly finished my control cabinet but i need some labels for the switches etc where did you get yours from ?

How do you calibrate the cnc on the DDCS V3

This came out incredibly nice for a DIYer. How did you know how to do all of this?

Thank you for this series. I have similars needs, so will be building a similar controller

Excellent build, question from a total newbie to cnc. How is your enclosure performing? and I have bought a RatRig 1500mm x 1000mm cnc will this enclosure system work ok with it?

Hello,
What chuck size is your 4th axis set? Are you happy with it now? Thanks

Excellent series. Detailed and very well explained. Thank you for taking the time to make these videos and for sharing.

Very good presentation and nicely-organized! Lots of useful information, and it was helpful in planning my own DDCS setup.

Excellent explanation and useful for everyone. Thanks

nice project and thanks :) but for box you could use metal pc case ,it is big and have space for psu where you can put vfd to move him from drivers even more (case have some metal separating pcu from rest) ,plus it is metal so you have free grounding

I am fascinated with this, following your idea, it does something similar, it works for me, but I have 2 concerns, the first, how do you connect the keyboard, via USB to the ddcs? I am referring to commands in the ddcs, the Bluetooth indicator on the keyboard lights up intermittently, but does not connect, and the second, the surge suppressor diode, I am not clear about its function, thank you for sharing your knowledge, att León Anchislavsky

Hi sir pls tel me how to speed homing pls

Hello,
I wonder if this controller is interactive like Mach3 ?

Meaning is it possible to type Gcode in a command prompt let's say to cut a straigth line?
Thanks

Can we upgrade to ATC??

Hello Robin
Very fine workmanship. Well done!
I am in the process of building my CNC machine and I have chosen to use the DDCS v3.1 controller.
The issue I am running into concerns the limit and homing switches.
My plan was to use the left/rear/upper limits of the machine also as home position.
The left (X--), rear (Y--) and upper (Z++) are not only connected to the linit terminals of the DDCSV but also (with a wire jumper) to the home terminals of the controller to not only serve as travel limits but also as home sensors.
I am using Hall Effect proximity switches as sensors. When the magnets come into range, I get a 12 volt signal at the corresponding input terminal.

Here is the problem(s):
1. None of the limit switches stops the travel
2. When the gantry is in the Y-- (home) position, it kills the output to the Y-axis stepper driver in the Y++ direction

I have experimented with all combinations and permutations of the Home and Limit parameters (soft limits are disabled).

I wonder if you could share the parameter settings for home and limit. It is very difficult to find information on line and the manual is difficult to interpret.

Thanls in Advance

Excellent work on this series, I will be referring to it religiously, now that I have decided to get rid of Mach3 for my 6040. The DDCS seems to do exactly what I need, and what bugs me about my combination of cheap breakout board and Mach3.
A question: Have you considered integrated servo motors like the iHSV57? I've used them on my machine, and except for their power requirements being higher (necessitating a new PSU), they were a near drop-in replacement for the steppers. From my limited understanding, the advantage they have is that they maintain their torque over nearly their entire RPM range, whereas steppers lose a lot of torque in the extreme ranges (low and high). Plus, they're closed loop, and at least on my machines, significantly faster.
And even if none of that is appealing, the fact that the driver is mounted to the motor means you would free up significant amounts of space in your cabinet ;)

I was also wondering if it is possible to combine the functionalities of your different e-stops simply by wiring them together. Wire the pendant into the external e-stop circuit so that hitting the pendant will perform the same way as the external one, and vice versa? Would that work?

hi, great job.
So you connected all the stepper and spindle shields to the AC power ground?
I have to wire the electronics of my cnc and I would like to do things better.

Creative video, thanks :)

Thank you for the great video, you did a great job, and very neat work. I'm not going to tell you that you did anything wrong, so that I may distinguish my comment from many of the other viewers :) Thank you for the information, i'm going to use a lot of this when I build my enclosure next week.

Make sure your watercooling lines are free of kinks. I noticed they are restricted at the exit of the motor and at the tank. Fish tank pumps do not have enough power to overcome a bent hose. You can use a big spring around the hose to prevent bending

Any updates /regrets about this controller

On the DC power wires, you should twist the two wires together which provides a certain amount of self shielding, and cancels out any emi that is present on the power leads.

Grounding is not going to help if you have the VFD in the control box --- DON'T DO IT ----

Hi. How did you get the closed loop to work with this controller? I’m having issues after connecting new closed loop stepper and driver. Doesn’t work at all. Can’t get it to work in open setting without encoder too. Works fine with regular steppers and drives.

Gracias por compartir tus conocimientos, tengo un problema con el eje A, al minuto de funcionamiento el driver enciende la luz de falla, revise todas las conecciones y están todas bien, tu sabes que parámetros de la controladora debo cambiar?. Saludos desde Chile

very nicely done. I have done a build that's 99% done but its a lot more rudimentary than yours. You make me want to redo everything.
My bed is 2m x 2m and my Z travel is 300mm to allow for my 4th axis

Hola, gracias por responder a mis preguntas, podrías decirme si es posible, continuar un trabajo desde una línea de códigos,. Al quedar sin energía eléctrica, para no empezar todo el trabajo nuevamente. Gracias espero lo entiendas. Saludos amigo desde Chile

Thank you so much the very detailed step by step video guide. It is awesome! I'm in the process of gathering all the components and an enclosure. I would like to know what gauge wires should one use all the different low voltage DC cabling between the psu's and the signal wires from the motor drives to the DDCS etc and the 4 core shielded cables you have used for connecting the GX16 connectors. Because shielded cables comes in various gauges, if you happen to know how many strands per wire and thickness might be helpful. In my case I will be using a simple Arduino Uno3 with a screw terminal shield.

Thats awesome video, thanks!
im having problems with my CNC. When i turn on the system, the step motors on Y axis change position just a little bit i can see the gear moving over the guide. Any idea what is going on ?

You definitely need to protect coolant hoses from bending. And maybe add some radiator, because it's can be not enough.

Hi! Love this series! I bought a second hand cnc router that has a ddcs v2.1 but the limit switches are not connected. They are allready wired in serial and it looks like you did the same or? Could i connect one end to ground and the second to limit x- and brindge this to limit x+? I guess i will try this if i cant find an answer somewhere. Best regards!

if you want to spend 1000 euro for this ok

What cam program do you use to make the g-code? How do you transfer it to the Controller?

Коллега, ну и компактно вы всё уложили в шкафу😂

Hi love the video and information I'm struggling with the home limit switch connection and can't find any videos or wiring in the 1 video said you linked in your page but I can't seem to find it.
Thank you

Great upgrade, excellent video. I hope to upgrade my CNC on similar lines. If you want high repeatability in limit switches, consider using an optical limit switch, they are dead accurate

hi do you know what aviation connector i can on my 1.5kw spindle ive been looking ate them and they all seem to be rated at 5A but iam sure that that is tool low, i want to put my vfd in a enclosure like you and use a aviation connector like you have for easy connection,any advice appreciated thanks

Hello mate. Dou you plan to make a new update to the latest build? Would it be possible to make a wire diagram with the newest parts you build in?

How would you do the wirings if you're using 3 closed loop stepper motors and drive?

Very nice build ! but that cooling setup is so funny 😆

Good job ,all set perfect wiring and conections.

wow awesome vid, this is going to help a lot since im currently planning and designing my DIY cnc machine

Very nice series

Thanks a lot.. greetings from indonesia
