DIY 4 axis foam cutter and DevCNC Foam

- This is my new Hot Wire CNC Foam cutter.
It was quite a long time that I didn't mess with foamies.. After some time spent designing this CNC foam cutter, these are the first attempts to cut wing panels.
I use DevWing Foam to design half wings and DevCNC Foam to cut them.
This combo is superb!
Some tuning must be done and there is a lot more to learn, but the overall quality seems really good!
I recently went from linuxcnc to devcnc and devwing foam2 . Made such a big difference. Great software. Nice job on your cnc.
Nice, I saw a cut of yours on devwing forum. Now I'm playing with a 3 axis CNC machine.
@@MrBigattone I won't be posting over in those forums anymore. Had a really bad experience with the owner. Banned me for trying to share the cool stuff I have been making with the software. Really don't ever want to talk to him again.
@@thenatedog Really?
I know the owner by forum/email/test softwares and I have never had bad experience with him.
I use his software when I cut with Foam Cutter an I like them.
What was the problem?
Pm if You like, i'm pieri70 around RC forums (RGGroups and others)
Ciao
@@MrBigattone when I got unbanned I went to one of my forum post to answer a question somebody had about a video and I was going to tell him that I was sorry that I hadn't gotten back to him in a couple weeks as I had been banned and I didn't know why which was totally true I didn't know yet. Well he didn't like me saying that so he removed the comment I can't even reply to the guy. and the section where you introduce yourself I shared my video of my 8-foot flying wing I designed it and cut by hand with metal fishing wire and for some reason he didn't like that. I think in his own words he said this form is not for excitement, whatever that means. In the dev foam section I showed my video on how to make fuselages and he removed that video because in it I actually made the comment that I purchased that instead of the fuselage software because it wasn't as expensive and so he removed that video and it's just like it's not a creative place that I want to share my stuff with anymore it was just not enjoyable experience at all that I want to come back.
Sorry for that, I saw some of your videos and they are pretty nice projects. Now I'm building a CNC router by myself, as soon as I'll return to foam cutting I'll take some ideas of yours.
Hola Pietro!! Esta muy interesante, podrias compartir los archivos en algun sitio de los de impresión 3d? En RC Groups no hay nada relacionado a esta maquina, saludos!!
Not bad for a first attempt. The wire is much too hot. The ideal temperature causes fine strings of melted foam to trail behind the wire. This gives the finest and most accurate cut. A bit of trial and error and you will get it. Nice machine.
Thank you. Yes that was my first attempt and was with 0.2mm NiCr wire. It was 3 years that I didn't cut any foam.. Now I cut a lot of pieces and fine tuned current/speed. It's fine
Great vid! How much weight was used to apply tension?
@@elwynj5379 300g if I remember correctly
@@MrBigattone many thanks. I’m slowly rebuilding my 4-axis foam wing cutter I built decades ago. It worked fine using GMFC software, fence posts and drawer runners. It did struggle with steeply tapered cores. It used springs/rubber bands for tension. Pulleys and weights is a great idea.
Can It work with GMFC prg?
Good job,
How are you making an electric connection between the wire and the bolt? As far as I know, the inner part of the bearing, which is in contact with the bolt, is not electrically connected to the exterior part of the bearing, which in turn, is touching the wire...
Hi, with crocodile clips on the bolts that hold the v-bearings in place. You can see it at 3min. Inner part is in connection with outer part of the bearing by mean of the metal balls.
nice work. Reduce the current its too high temp
Hello Pietro : Congratulations for your fantastic foam cutter proyect , I belong to an spanish rc plane foam cutter entusiast , and whe have some machines working with belts threaded barrs etc . but your solution with a belt reduction seems perfect ¿ what is the reduction relation that you are using ? ¿ is posible to share wit us the stl files of the plastic parts ? thanks Antonio Medina
Hello, thanks
I think I used a 1:3 (20 to 60 teeth) reduction from motor to belt axis and then 30 teeth to the driving belt.
It's GT2 2mm belt.
For the stl, search my user on RCGroups (pieri70) and let's get in touch there
@@MrBigattone Thank you so much , I will follow in rc groups
Ciao Pietro volevo chiederti se puoi condividere i file del tuo progetto, personalmente mi piacerebbe molto costruirla. Grazie
What is the profile on y rail?
Open builds 20x80
Hello, how is everything? Friend I'm building a hotwire and stopped at the software part. I did a lot of research and saw that DEV software is the best. I saw that the friend is using DEVCNC FOAM. In your case .... Could you give me the software? Or give me a tip where I find the license?
Of course you can buy it. I did
nice CNC , what steppers you using NEMA 23?
No, nema17 and for Z old nema17 not so powerful..
Hi Pietro, Im really interesting in you design. I tried to get the STL files from RCgroups and I didnt find it. pls, could you share it? thank you
I didn't export them. I must do it..
may I order one machine?
Hello it's not for sale. Or better, I don't know how much should I price it..
@@MrBigattone would You supply 3D printed parts and help with electronic so I can assemble it myself.. I'd pay for help
