Looks stunning 😲 well done that’s excellent 😀
My friend, it didn’t turn out bad! But I want to give a little advice (when working with epoxy resin, surfaces where the epoxy resin should not get in, rub a thick layer of wood polishing wax, let it dry, it won’t take long, and only after that glue the masking tape on top. This is significantly more will make it easier to post-process the part as a whole, since where the wax was applied, the epoxy resin will not stick, and the masking tape will peel off very easily).
Yes, I certainly think so.
thank you for the advice.
Просто продолжай делать это, нам всем очень нравится. Моё уважение.
I think it looks incredible! I am so excited to see where this goes. I hope it has the performance you're looking for.
Remember there is a big shrinkage in most epoxy when curing as well. West system epoxy only 0.01%!!!! Wonderful video
Работать с эпоксидной смолой - это гарантированный путь к тому что всё будет в эпоксидной смоле. Как сильно не стараться быть аккуратным, всё равно всё будет в смоле :)
Chopsticks saved the day! Great work, you pushed through the problems and the resault looks very good! That's the point for me, doing something for the first time and not letting anything stop you. Friendly advice, i'm the first to rush to do something, but wear gloves at least when working with this stuff. Looking forward to the next video!
At that time, I was getting frustrated because the work was slower than I expected.
I made a lot of mistakes, including the one with gloves.
I should do everything calmly.
Respect. Very interesting. Your designs and methods are opening my mind, I will be following closely as you progress!
In the end it looked better than I was expecting lol
Very good, less drinking and more thinking my good man.
this gives me some great ideas. thank you.
Impressive!!!
Gran videos estimado, se agradece el esfuerzo , saludos desde Chile ✌️
A great job, to pour epoxy resin with particles, through small gaps and so that it does not spill, it is better to pour the mixture into a plastic pastry bag. a greeting from Spain.
Thanks for the advice.
3 words; slow, cure, epoxy. great video. great machine. im building something similar. 600x700x600 mm (x,y,z). 12"x 28"x 18" once all the axis are on. mistakes are hoe we learn and i love to learn from OTHER peoples mistakes. thanx for the video. i enjoy everything you build.
Thank you.
I would be happy if I could help your project by sharing my experience.
@@a-cnc-f you have helped me considerably already. i think i've watched every single one of your build videos.

Nice ❤❤❤❤
"all the beautiful women who watch this channel" ahhhhh should we tell him?
Nice! Sweet.
BTW. There’s another type of masking tape. The white one you use is cheap, try the blue or yellow that is more sticky. But the price is double. That’s the one professional painter use. It is excellent quality and it will minimize your work.
thank you for the advice
Forget to mention, even if it is more sticky it is more easy to remove. Good luck man. @@a-cnc-f
ive never seen someone pick up liquid with chopsticks so effectively
Japanese and Chinese can use chopsticks like their own fingers.
Fantastic. Im curious about the cnc control. Will this machine be capable of simultaneous 5 axis motion?
Whether simultaneous 5-axis control is possible or not depends on the controller.
I use Linuxcnc, so simultaneous control of 5 axes is possible.
That is very useful, you could make and sell some checklists as merchandise on how to do these detailed stuff.
Thank you. I'm glad.

日本人にしか分からない冗談ですね！
多分食べたら、色々な意味でマズイです。
Hey there if i am to buy your plans for the small lathe will it include buildind instructions and parts list?
Special guides are not included.
As for the manufacturing process, you can get a general understanding by watching up to part 8 of this video series.

👍
Does 5AXIS recommend the MACH3 program? Do you recommend MACH4? Which do you prefer and apply?
Mach is a paid software that is compatible with windows and seems to be easy to handle.
I only use linuxcnc, so if I had to make a recommendation, it would be linuxcnc.
I chose linuxcnc because it is free and has a lot of flexibility.
The disadvantages are that you need to learn to use it, and you need to have a dedicated PC that runs linuxcnc, not windows.
I think raspberry pi4 is a good choice as a dedicated PC.
@a-cnc-f thanks bro~
i think if i ever got into doing epoxy granite machine parts, i'd cast them separate from the metal plates.
There are two reasons to use plates.
1) I need a perfectly flat surface to mount the linear guides. Since this is an environment where large machine tools cannot be used, a perfectly flat surface is needed once the epoxy has cured.
(2) The machine is designed to be compact, so thin sections are needed. These parts are the thickness of the plate.
@@a-cnc-f yah, you have a VERY complicated design and it'd be hard to get it flat with any potential shrinkage, without using an embedded plate. the smallest thing i'd be using that stuff on is probably a metre on a side.
Looks like you attached the rails and blocks during the pour to attempt to hold the alumuinum plate flat, if you read the hiwin spec - you'll see this won't work, even the highest spec linear rails aren't straight or flat, its a common misconception - its an artifact of how they are ground in manufacturing and why they can make them so long, if you try to set the slave rail using the first rail the carriage will slide but the tolerances will be terrible on actual manufactured parts.
To achieve the kind of specs and tolerances you want you'll have to either mill/grind/scrape flat to spec the reference surfaces of the master rail - then scrape/shim and force the other rail using an indicator on a block on the master to set the slave. Watch some of Piotr Fox Wysocki series on his granite CNC build for micron precision.
You are correct.
The straightness of the linear guide is not that accurate.
The straightness of industrial machines depends on the accuracy of the linear guide mounting surface.
In other words, it is the machining accuracy of the bed.
Straightness is achieved by using retainers to press the linear guide against a reference plane.
However, these methods can only be used when sufficient facilities are available.
However, I do not have such facilities in the room where I work.
In this situation, I need to find the best way.
In the first place, it is a stupid idea to try to build a CNC machine as a DIY project in an ordinary room.
First of all, it is a lot of work just to make a machine that works properly.
After that, I try to make it as accurate as possible.
@@a-cnc-f indeed - I’m not trying to dissuade you. It’s certainly possible to get good results in the home with only hand tools if that’s the aim of the project, it would be a real advantage to have a surface table who’s diagonal is over half the length of the longest rail and a dial test indicator - you can’t fix what you can’t measure, and they’re quite cheap these days.
Conversely if you’re trying to make the best machine you possibly can, reach out to some local machine shops - you’ll be surprised how many will help you with a little job like that for free, it’s only a 20-30 minute job to indicate those surfaces in and mill them flat with a straight edge.
@@washy934
Thanks for the advice.
I understand what you are saying.
I also understand that it is better to make a machine with high accuracy.
But it is also important for this project to be built in this small room.
I want to challenge how far I can go with the limited facilities.
If it becomes absolutely necessary, I will do as you say.
@@a-cnc-f If you know you are going to eventually put the effort into flattening and making co-planer (etc) for more accuracy it seems to me you would have been better off really leaning into that and not putting the rails in harms way at all in the first place - hold the shell as stiff as you can with scraps of angle so it can't blow out too stupidly. With patience you absolutely could 3 stone method it perfectly planer and in the process create some suitably flat reference 'stones' for each subsequent operation and part that are sized to your machine and space. (though I'd look for a machine shop nearby to skip to the end finishing stage with confidence it wasn't that far out of flat - I don't mind a challenge, but I also want to actually finish a project I start before life gets in the way again).
Edit: But don't take this too negatively - its an impressive looking start and project.
I believe you can get good results by getting a 400x400 or so granite surface plate and mounting your gantry on it with a 3 point method. Then you can inspect flatness of your parts and correct. By rotating your parts 90 degrees you can then set one rail straight by adjustment using the surface plate and an indicator. From that you can get closer to an aligned machine. Such surface plates aren’t very expensive. You may even be able to use it as a machine base when the machine is built, bolting your machine to it with threaded inserts to give the vibrations a place to go. If you haven’t seen Piotr’s videos as OP suggests you will be delighted at his learnings building machines from granite plates and beams. Gives me ideas, what if the granite beams were laminated with carbon plates as you have done? Could be incredibly strong and stable.
It is sad that your civilization have not invented funnels yet
You don't listen to advice :(
Stones don't make sense in polymer concrete for such small shapes.
大きな石を使うと、エポキシの比率を下げることができる。
私はエポキシ御影石の流動性を重視していますが、できる限りエポキシの比率を下げることで、より丈夫で強いエポキシ御影石になるはずです。
@@a-cnc-f The filler does not have to be a large fraction. The filler can be sand. This will ensure excellent cavity filling. Experience shows that the best ratio is 20% resin and 80% sand.
First you need to mix the sand and resin of component “A”, and then only add component “B”.
@@AlexMoonXXI
Basically I agree with you.
In my experience, I think 20% is about right.
The most important thing in making epoxy granite is to remove as much air as possible.
I believe the next most important thing is to reduce the percentage of epoxy.
To do that, it is easier to use the largest gravel possible.
Pure granite should be harder and stronger than any good epoxy granite.
Pure granite should have higher tensile strength than epoxy.
I believe that including as much large gravel as possible will bring it closer to real granite.
I was told that the percentage of epoxy in industrial epoxy granite is about 7%.
So I decided to first pour the epoxy granite made of sand and let it fill the corners before adding the large gravel in the center section.
@@a-cnc-f You should scale industrial products and your machine. How many pebbles will fit in the cross-section of your frame?
Don't reinvent the wheel! Use the experience of your colleagues. For example, watch the video titled "How to Build Epoxy Granite Machine Base"
When I decided to build a machine base out of epoxy granite, I of course looked up information on the Internet.
"How to Build Epoxy Granite Machine Base" I also watched this video.
It explains it very logically and is based on experimentation.
I am definitely heavily influenced by this information.
I agree with everything that is said in this video.
I have done similar experiments myself.
I came to about the same conclusion.
I found that about 20% epoxy with just sand without gravel worked best.
But is this conclusion perfect?
You say "Don't reinvent the wheel!", but I am of the exact opposite opinion here.
Isn't the reason for making the final product with only epoxy and sand in that video to clean out the air?
If he could have used gravel and still perfectly aired it out and lowered the percentage of epoxy, wouldn't he have wanted to do that?
I figured that putting an aluminum frame inside as an aggregate would narrow the space between it and the formwork.
So, I made an external skeleton with carbon fiber plates as aggregate so that I could create a large cavity inside.
I thought I put 1cm to 2cm of gravel in it so that it would not be a problem.
Hey brother, how do i get in touch with you 🙃 as someone who is a legot robotics engineering, i would like to helo out some time 😇
Drop a link to your business email or whatever and ill send you a mesage 🙃
Thanks for your interest.
I try to keep my personal information as private as possible.
I do not accept work from anyone.
I would love to build a machine out of real granite.
