Jeez, in less time than you used to describe the AI feature I had already gone through the process in my brain switching from what I am using now to SolidWorks.

@@RobertCowanDIYI could forsee general LLMs getting smart enough to describe the interfaces and the rules the user wants, piped into the generative design tools that are increasingly getting powerful such that you could describe something, and faster than you could possible design it, a suitable enough part is created, especially for quick "I just want an adapter" type projects. Tech is moving so quick I can easily imagine every CAD programs starting to have their own general AI assistant where if you get to some annoying part you just kinda say "Redo this whole section but like 2mm wider and adjust the formula accordingly" and through context it'll do what would have taken you an hour of fussing with annoying systems.

@@RobertCowanDIY Agreed. But there are some parts of modeling where I sure would appreciate having less steps like surface patterning, threads, etc. Regarding the magnets, I have always thought surface area was the idea, I never considered total mass as a way to increase strength without increasing the area of the mating surfaces. This is one of those reasons where actual schooling rather than self-taught provides a better foundation for success.

Great video. Love the thin material left on the print for magnet retention.

OOOOH, good idea!

7:40 if the orifice for the magnet was deep enough you could do it but then your flange gets unnecessarily thick to account for slot. You would put in magnet then Put in a Shim then let the print finish to lock it in place. Robert you probably know I meant bit others may not. The problem with embedding is that if you sell or discard pc. It’s worth recovering the sometimes expensive magnets. An embedded magnet is hard to remove than just pushing them out with a toothpick. If you have smaller magnets you could use the halbach array method to amplify the magnets. It makes a 10lb magnet array feel close to 20lb pull force.

They can be recovered easily enough with other magnets ;-) Just stack them up and slowly pull out the stack. This isn't my first rodeo with magnets.

@75keg75

@@RobertCowanDIY when I said it is harder to recover I meant once you’ve sealed them in. Ie put a slot, drop in magnet, shim magnet, continue print to seal orofice. The only way that’s coming out is a destructive recovery. pulling magnets on tight fitting parts is feasible for sure. But to be foolproof adding a tiny hole to push the magnets out is handy. For the part I had, the magnet was unlikely to pull out as the orofice was just smaller than magnet and the force holding magnet in place was more than magnet force. Have you tried a halbach array - I was impressed by an 8- 10x10dia neodymium magnets array. Possibly best suited to a different application than your duct, but cool to check out if you haven’t come across them.

@@75keg75 I usually add a small hole to push them through BUT in this case I was worried about debris getting into the hole and causing an issue with a snug fit. Once again, over-thinking a design that works just fine.

Love this solution. I am always a fan of using magnets to auto-align couplings. Are the plates on the fiber lasers aluminum? If not could magnet to the plate. Also curious, what use cases your 3 lasers fit.

@RobertCowanDIY

5 ай бұрын

The base plates of the fiber lasers are aluminum, so magnets won't work unfortunately. The CO2 laser is for most things. I use it for making little cardboard jigs (just goo for testing fit or layout of things), engraving wood, cutting acrylic, etc. The fiber lasers are for marking metals or engraving on anything the CO2 can't do.

For a rev 2 of this you could put the index nubs as triangles so it is more self centering than you have. Also you could print a soft TPU gasket that you press fit into a groove. The squish from the magnets should create a full seal. The perfect printer is the cheapest than you can print with. Much like the fastest car in the world is a hire car! 😂 Merry Christmas!!

This was prototyped pretty heavily and they seat perfectly fine. I've had zero issues with them finding their way in. Look closer at the models, the 'nubs' are all chamfered on the receiving and and it's nearly impossible to not get it to seat flush. TPU would have been a nice addition though.

@@RobertCowanDIY I was watching on an iPhone just after I woke up so I didn’t see.the Chamfers - which will definitely act like a centering triangle. TPU definitely worthwhile for a dusty system but as your extracting fumes it probably not worth the hassle. The vents on back laser are probably bigger than any gap on the flange faces.

Good thoughts. I like magnets in my designs too. The only thing I would do differently is to use a rectangular shape for the duct. Or better said something with a 45 degree top if you printer can’t bridge nicely. It would avoid the need for supports and allow you to get the laser even closer to the wall. Designs for a 3d printer needs some change in mind. I am not sure if I would like to have a 50W laser without a sight protection either.

Round ducts are better for airflow. The elbow is already as tight as I would like, any tighter and you will impact air flow. Ideally, I'd want it much larger, but I'm restricted by the size of the duct. Supports have come a long way and both parts print just fine with supports and were designed with 3d printing in mind. The fiber lasers have goggles down below, which you can see when I'm down next to the HEPA filter. Also, the computer that operates the machine is opposite the lasers, so my back is to the machines while they're being used. Most jobs are less than a minute, so I just hit go and by the time I turn around, it's done.

@@Newmeishu Eh, it's a $5K machine that comes with a lot of instructions and requires a fair bit of know-how to get working. I am just showing off projects I'm building, I don't need to be an OSHA instructional manual for people. Dumb people are gonna do dumb stuff and it's not my responsibility to stop them.

An idea for the fume extractor nozzle for the open printers. Put it on a metal plate that about matches its size and have a single smooth pin sticking down beneath the plate, just the right size to drop into the holes on the bed. Then you can just set it on the printer and the weight of the metal will hold it in place with the single centered pin keeping it aligned. That way you don't have to mess with screws every time, and you can move or pivot it anywhere you want.

@RobertCowanDIY

Fair point but all the holes are threaded, so eventually the pins would damage the threads. PLUS, I won't really need to move or adjust the duct very often, it's most likely going to stay in roughly the same spot each time. I did think about a method like you proposed, but I went with shorter thumbscrew so it's only a few turns to remove them. Another interesting idea would be set screws set below the surface and magnets... The magnets would hold to the set screws. Lots of ways to do the same thing.

​@@RobertCowanDIYOhh, the set screws with magnets sounds slick! Gonna have to tuck that one into my archives for future use! Lol And yes, wearing the threads over time is a good observation, especially with aluminum. That could be addressed by using a plastic pin though. If it doesn't have to move frequently, that also changes things a bit. I know that if I was having to move it for every job, the thumb screws (which wear threads out with constant use as well... ;) ) would trigger my unnecessary repetitive task annoyance, and I would end up finding a pipe wrench or something to set on it to keep it in place lol But the magnets on set screws would be even nicer.

I was told that type filter is not safe for use with acrylic work. Xtool told me the P2 should be vented outdoors when working with acrylic as their filter cannot remove the harmful fumes they found after testing.
