That transition was slick Edit: I mean this in the nicest way possible. The outro gave me some real middle school science class movie day vibes. I loved it.
Seeing mods like this makes me want to upgrade my Voron again, but then again i don't want to mess with it cause its in an working state. Really looking forward to the Voron Tap video. Still undecided on upgrading from kicky. But it looks way more reliable than anything else.
Note that once TAP is installed, you could print some features onto that carbon fiber plate, then take it all over to the CNC and cut a finished part out Additive + Subtractive processes on the same part.
Good idea for the filtration and vacuum when milling carbon fiber. You may already know this, but just in case you haven’t run across it - carbon fiber dust is conductive so you have to be careful with electronics nearby as the dust can get in there and cause you some electrical issues later on. Great video!
The RU-vid algorithm never notified me that you existed… shame on it. Nice concise video about something I haven’t seen anyone else doing. Thanks for sharing.
Advancing the skills and abilities is what it's all about. I was talking to someone about printing ABS and they were like why would you want to print ABS instead of PLA? Aside from the obvious superiority of the material for certain applications, its really just to improve the process. Good stuff.
The entire additive manufacturing angle on industry is becoming increasingly interesting in general. Just a decade ago I wouldn't have imagined stuff like what's being done by companies like DM or Nano Dimension, let alone a dude in his home doing carbon fiber printing. Amazing world :)
Great video! Glad you mentioned the issues with cutting carbon fiber. That stuff is nasty. I'm excited to see the adxl graphs/ringing difference between the printed and cnced gantries.
Yeah, that's not sawdust. Carbon fiber dust will literally embed in your/your kids lungs like miniature needles. IMHO, a shopvac really is not sufficient safety. Ever seen Pagani cutting CF on RU-vid? They literally wear spacesuits.
You could also have gone with fibre glass, it's almost the same but much cheaper. Carbon fibre has it's place, but if you don't do it for the cool factor (as you said) it doesn't make any sense. You can achieve the same thing with glas, it's just a bit heavier: And since this isn't a fast moving part, you wouldn't notice it. Just a heads up to anyone wanting to do something similar. Glas is at least 5 times cheaper than CF. In 3D Printing people know it as gyrolite, G10 or FR4. It's literally all the same stuff.
This is really nice step by step, I love the video! And the following comment is only meant as constructive feedback. As a humble mechanical engineer, I believe that the stiffness haven't improved drastically with this new design. Yes CFRP has some really good stiffness properties. But you loose a ton of co-planar stiffness with the polymer spacers ( they have a small diameter, and they are quite weak in compression forces). So with a few minor design adjustment's, the stiffness could be greatly improved. Upgrading the spacers to GFRP/CFRP tube spacer's cut at the correct length (and straight cuts). Increase the number/diameter of spacer's. This would give this box construction a high degree of stiffness in most directions.
There is another way to make CF parts. Use your printer to make a female mold. You place the fiber and the epoxy in the mold and then press it with clamps and let the epoxy cure. Then take the mold apart. The trick is making the mold, you need to sand and polish the inside and coat it with mold-release wax. Or print the mold in water-soluble plastic and soak it. The parts can have any shape you like. Maybe you have to do some very minimal machine work, like reaming holes.
The resin matrix in that carbon fiber is a thermoset rather than a thermoplastic, so if you get a sheet with the right epoxy it should be able to handle high temperatures (higher than the ABS you'd previously used). Aerospace-grade epoxies can go up to ~300C without deforming. This is actually the reason why thermosets have continued to dominate the aerospace markets - it's only fairly recently that thermoplastic resins like PEEK have started to get up towards the required temperatures.
The locating feature is parallel to the screw holes, just use a second pi3ce of carbon with the same holes cut, or do a 3d print 2mm thick by 3mm thick with screw holes and have a sandwiched piece, itll work Great.
When you cut carbon fiber plate, do you ever seal the new edges you created with epoxy? Maybe the cnc cutters are good enough to leave smooth edges without chipping or fraying.
for the locating features, you could cut slots into the plate and glue in some sort of key that is then proud of the surface of the part and works as a locating feature.
I just generated DXFs from the sketches off the existing CAD model and did a few "manual" tweaks in carbide create to get it to a workable state Unfortunatly that also means the final product isnt exactly something im confident in sharing
Most of my voron is aluminium; I'm actually considering making the extruder from carbon fiber, aluminium or even steel at the moment using my big CNC. But: I do like the carbon fiber idea, it might actually be better because it's so much lighter. I do agree that you have to be careful with that stuff... these fibers are very carcinogenic, and they will give you cancer if you're not careful. The components you have there are some of the ones I have made from aluminium. In fact, i used conical spring washers for mounting the idlers. You can really put them in as tight as you can reasonably can, and they will make your prints more stable because the bearings have no place to go. As for the benefits that people ask about in the comments? Basically, if it's more rigid and stable, you can throw more force at it and still get the same results. There's little or no wear and since nothing moves, the speed matters little for the precision.
I actually just picked up a used Shapeoko 3 for a whopping $125usd. The Makita router it came with is worth that. A no-brainer. I've been wanting a CNC router at home for years anyway, since I don't want to experiment and cut weird things at work. The problem is, with being used to 5'x10' machines, the 16"x16" cutting area seems almost useless. Might have to use the machine as a building block to build a larger machine. We'll see what actually happens. I haven't even put the machine together yet. 😅
Nero, it would be awesome to see a video on Tap. I know things are subject to change. But it would be nice to see an overview on it, what would need to be changed, etc. I completed my 2.4 a little while ago, using a lot of your videos to help me through the process, since I'm a noob. I have been happy with my Omron probe up to this point on Stealthburner, but am considering if tap is a wise upgrade for me.
Useful video! I'm about to machine a new CF midplate for the dual 5015 hotend setup on my SK-Tank...it'll be replacing a printed part, and should be a perfect job for my MPCNC (running Duet and RRF). Quick question, for the CF gantry on the Tank, Ernest recommends sealing the edges of the CF pieces with superglue, but I didn't see you do anything like that. Do you feel it's not necessary?
True, and this is why ill be keeping an eye on it for a potential followup But also i tend not to run my machines crazy hot so on paper im not hitting those temps
I consider reprinting everything in PC blend but I could mod my cnc to be able to cut aluminum… Not sure yet. In the end I want a heated chamber to get to 80-90c.
Opinions on using lasercut stainless steel for these parts instead? That's what I'm considering for upgrading my setup. As I see it, rigidity is roughly the same as CF, it is heavier but since this is not moving mass it is not a problem. And it can be done pretty cheaply in a lot of shops. Granted, it doesn't have nearly as much glam as CF, but as a pragmatic option maybe?
Not related to the CF parts (which look reaaally neat btw !), yet curious about TAP. Using optical switches over mechanical ones, ok, yet why not piezo discs ? Like piezo probes, you know. Besides extra electronics, of course.
Not really, the material costs+time it takes to machine+shipping+the need to make a profit on it for it to be worth my time really doesnt make this scale of manufacturing parts a viable thing
Love this content… Keep up the good work Sir. Crazy question…would you ever consider klipperizing the CNC (not sure what/how your CNC HW/SW set up is, will watch the live stream)? I have an MPCNC and love the klipper environment and was thinking “what if I klipperized it”…at the end of the day, the main board/SW is repurposed 3D printer/marlin based…why not?…thoughts?
Problem with that is klipper is missing a bunch of the gcode commands CNC machines use to operate, even RRF requires i do some post processing to the gcode to make it happy
If you like Klipper but want to drive CNC, Look into "Linux CNC" or just "LCNC". CNC is more com[plex them printing. For example, think about a ball end mill. The tools can be of different sizes and shapes. Let's not even talk about 4 and 5-axis machines. In this video, we saw only very basic 2D milling.
So im still pretty new to the at home cnc stuff, a 3018 or comgrow robocnc like im using here are relatively cheap and beginner friendly, albeit limiting in capabilities
I was planning to say "when will we see a new tosty boy aka vulcan man made out of carbon fiber, heat resistant enough to print that ultum/ peek spool you have laying around somewhere." but since appearenty the resin melts at higher tempretures, I'm not sure anymore this is possible hahahaha not gonna lie would be cool to see you make an entire printer with carbon parts and a "homemade" printer capable of printing ultum hahhaha
Spacers and lack of centering features on lower dimensional accuracy machine vs weaker material. Suppose rigidity gains would be lost in play... Kudos for CF machining, I failed dramatically trying to machine 5mm carbon plate for mk3s by hand.
I love how everyone likes to be an environmental health & safety inspector with their safety warnings on RU-vid 🤣 We drill and cut through stack ups of composite and carbon fiber on the F35 daily. Yea it’s not good to breathe it in but our own safety inspectors don’t come around acting like that with their warning 😂
Two reasons really 1 not everyone knows how to be safe around everything, so a reminder/overview in the video can help some folks 2. if i DONT do it, while the engagement would be nice, videos would get a ton of comments about how im NOT covering safety.
@@CanuckCreator not to mention it's scientifically proven that carbon fiber dust is insanely detrimental to your lungs. Everyone needs to be aware of that. It's as insane as people who don't wear masks when working with fiberglass resins. Haha. Kudos to being safe when publicly showing processes like this. The general population have no clue to the dangers.
