Arduino CNC Foam Cutting Machine (Complete Guide)

Hello,...we can't homing our machine....when ever we try to homing our machine get stop in mid way.. we can't handle this problem please help us😢😢

how much to if i order ready to use this this machine?

simple machine, good work

Theres no way its that simple.

Do you have a vid on how you built the compents cnc shield , pwm , ect. Im tryin to build one and im stuck at the how to connect the hot wires ?

La piezas 3d donde descargo los modelos

I prefer adrifoam x4 but its a paid software, still, works very good. Can do tapered cuts also

I need this.

Where can I find projects that can be made with a CNC hotwire machine?

Love it!

Can I buy your code

Hi can you give me the code

Money 1 pat

👍

Can this also cut oasis?

Do you sell these in a kit ready to assemble with all the parts?

I was wondering how much does it cost to built in

Thanks! This was super inspiring! 😮😊

It would be great if you would sell ready the machine

Hello. Friend, could you build 5 axes foam cutting machine, pls?

Would this design be able to be scaled up for larger pieces

👍👍👍

Anlatım için teşekkürler. Ancak ben ne yaptıysam ugs programı benim gcode görmedi ve makineyi çalıştıranadım. Ugs projemi çalıştırmıyor . Makine ayarlarımı yapıyorum ancak çalışmıyor. Yardımcı olur musun?

Hi, awesome project. I would like to know why I cannot download the file even though I have followed the procedure?

For the right price would you consider custom making one for me?

Total price

How do you learn to do this!? I could never have figured it all out!

Could someone tell me why didn't he use servos instead of steppers?

❤

Please help! I have been working on this project for a couple of months now. I am at the point where I need to solder the limit stops and connect them to the cnc shield. I have soldered the limit switches to ground and normally closed, however, I have no idea what connector you are using to connect the wires to the board. I bought 2.54 mm pitch Dupont connectors and a max diameter crimper of 1mm^2. I am unable to crimp my 18 awg wire to the female connecter pins because i believe the crimper diameter to be too small for the wire. I am a total newbie and have no idea what the problem is. Is my crimper too small for 18-gauge wire or should I be using lower gauge wire for the limit switches. Can I use other types of connectors?

I've been watching a lot of your videos (old and recent) today and want to thank you for you clear explanations, calm voice and how open you are about things that don't go how you prefer. Also with your videos you've given me ideas how to solve issues I had with my 3D model drawing. Many thanks!

This is a really rad build. It probably wouldn't be the most difficult thing in the world to build a slicer which could cut complex, non-symmetrical 3D shapes simply by rotating a model and casting the outline based on step resolution. Then just doing as you have done here, having the system slice, rotate, load new file, repeat.

what software do you use on it? Its an amazing work what you present here! 🙏🫡

i would love u to make one for me

hello nice vid but do u sell any machine

Why do you have power running to the top circuit board and not the one underneath?

Hi - Any idea where we can get a similar one? Might you have one for sale?

Why error homing?

Hi, I was building this CNC and I had a question, how much amperage are the drivers connected to the shield? I am having problems when I try to move the steppers with the application, they do not have enough power to move.

I have built this design in 2020 or 2021, but changed the dimensions to 600x600mm cutting area. Also, I removed the rotating axis and shrunk the width down to approx. 10cm wire length. I only do 2dimensional cutting, because the machine was built for bible verses, that we put as decoration on our walls in our church.
We do take on a few jobs per year, as my wife sews and sells some products and started some advertising for the letters. So now, the machine gets more and more uses. Moving into an apartment, where I have my own office/hobby room and can leave the machine assembled also helps. Beforehand I always had to disassemble the y axis and store the machine in the basement.
I use DevFoam Pro for CAM and make the design in Inkscape. The CAM is quite finicky, if you want really precise and smooth cuts. Cutting direction and order of cuts can make or break your parts.
Things I have noticed and solved so far (or want to solve in the future):
- the power supply for the wire is too big for my short wire (10cm of 0.2mm NiCr 8020), I use an LM2596 for that
- the printed clamps on the y-axis failed, when I tried to tension the belt. Have added some mechanical fixtures, so that the axis doesn't rely on the friction of the clamps.
- construction of some of the parts are sub-optimal for 3d printing. I did split some parts into multiple single parts and use heat-set inserts and screws to assemble them.
- I had to disassemble it quite often, and setting it back up was no smooth sailing. I splitted the xy-joining part and now I only need to remove the belts from the idlers and undo 4 screws to disassemble it. Setting it up is in reverse order. Only need to resync the two belts, but tension isn't touched, since the mechanical fix points make it very repeatable.
- I want to add some belt tensioners on x and y axis in the future. Also some belt clamps, so that you don't need zip-ties and gain some more travel.
- We noticed vibrations in the cut line, when the y-axis accelerates, especially from stand-stills. For now it is solved with slower acceleration values, but I want to add some tension wires down to the xy-joint, that way I want to stabilize my long y axis. I'm not sure, if this problem exists with your smaller machine :)
- Since I'm manually placing my letters on the foam and never cut more than one letter at a time, I got rid of the endstops. They are needed, if you want to use the rotating axis of course.
- $1 in GRBL needs to be set to 255. If you use G4 dwell on corners, like I do with devFoam, the motors will drop and you get offsets in your part.
Overall: Thanks for the design, it helped me very much!

Hello where i can buy whole machine?

This is so cool... if I don't find something similar to this in the college I am going to, I'm definitely making my own. Thank you

After editing my grbl master confh file then upload got problem saying "library not valid Arduino error"

Привет, отличная работа)
Вы в своих проектах никогда не указываете размер станка, рабочего поля. Можете его назвать?

What type of filament are you using for the 3d parts? Is it PLA? ABS?
