Hi all! I've discovered that Fusion 360 has had some problems simulation the beams with another material inside it. It makes those beams deflect less than they should. Watch this video if you want to learn how to simulate beams, but please remember that you cannot simulate something, with a different material inside it. Now other than that, Fusion 360 is still great for assemblies, with the epoxy granite beams being the exception.
It's quite a lot actually... I have started another build where i only use 200 N, and allow myself to have a maximum total deflection of around something like 0.01. I'm gonna start a build log soon, then i can confirm how stiff the machine is, and you guys can see what kind of cuts will be doable with the stiffness i end up with.
yes, 1.298E+4 means 1.298 x 10 to the power of 4. Just like 1.298E-4 means the number times 10 to the power of -4 (0.0001298). An engineers way of writing large and small numbers.
Yes. I've designed a really stiff gantry for the machine. I'm planning on making a video on how I used shape optimization in F360 to see where the critical loads in my gantry were located. I'm really busy with work at the moment compared to when I started this project, but it's not a bad thing, in two months' time I'll have to funds to realize this project. I've learned lots of new things about composite materials and I'm looking forward to sharing it all!
@@williamsgarageengineering6543 Even I am trying to build one. Made the design choices of gantry frame, steel tubes and epoxy granite. Planning to mill stainless steel and titanium and other hard materials. I will be lucky to learn few things in this regard from your videos. I finalized fixed gantry over moving gantry. Thanks a lot for your videos.
@rapoliit That sounds great, I'd be happy to follow your build. You should consider making a build-log on the cnc zone forum, people there are happy to help (as am I).
Really good information here! I’m designing my own fixed gantry cnc router and am learning a lot. Excited for the future videos!
Thank you Lotrias, I'm glad you found the video helpful. I'll be sure to upload a new design video soon😁

I cannot believe you don't have more subs
Is 1400 newton's a lot of force for a cnc or a normal amount?

@@williamsgarageengineering6543 OOOO! Yes, please make more videos, theyre actually so helpful
You didn not show the results of the "L" profile. Thanks anyways.
32:12 that is not a weird number. It is 12,9 kg. But I guess you figured that out by now.

Any updates to this project??
