Hey all - still kind of new to this but I have a wall mounted Onefinity X50 and I was curious if anyone has a good low profile clamping that doesn’t get in the way of the dust boot?
I’ve mostly been cutting it plywood and I’ve tried to maximize the material which often results in the clamps interfering with the dust boot. Also would be open to an alternative method for dust collection than the suck-it.
I agree with @Aiph5u - a vacuum table is a great solution for a wall mounted set-up. If you have a 3D printer and a small vacuum pump, you can make little pods that hold your material pretty rigidly. That is an inexpensive solution and good for getting a taste for how nice vacuum workholding really is.
That said, I have been working on a project to bring vacuum tables to this community of Onefinity users (since I am one myself). We just launched and I think our complete kit would work well for your application, especially for maximizing yield when cutting sheets of plywood. We will soon be offering a free 3D printable vacuum chuck, like the ones mentioned above, on our website to support people who are looking to experiment with this workholding approach.
I really respect the ethos of this community (among many things I respect about it) and would not be mentioning this here unless I genuinely felt I had a solution to offer. If this is too forward and promotional in nature, please feel free to flag this post and/or remove it.
These vacuum systems are very cool! An OTS solution is a bit out of budget at the moment but I do have a few 3D printers so i might try to design and print some vacuum modules and bury them into the spoilboard.
Also going to try to modify the OOPS clamps by swapping the thumbscrews + dialling in the screw length to make them a bit more lo-profile also getting a longer moustache on the dustboot.
I mention these covers because I find them necessary and want to have some. The challenge will not be the bellows themselves, but designing 3D-printed parts at both ends that take nothing away from the travel.
unfortunately you cannot see how this accumulates, as this is hidden inside the carriage. The one Onefinity showed here was only discovered when it began to block the ball screw, so maybe this occured months after the user had started to work with insufficient dust extraction / maintenance.
I bought the machine for a professional purpose so the maintenance that Onefinity expects from the hobbyist users is nothing I want to do. What I will do is try to use a very effective wood dust extraction, but you don’t really know how much the maintenance Onefinity calls the users for really prevents saw dust accumulating inside, or how much the wipers are able to catch the dust before it enters the ball nut / carriage on the ball screw.
I just know (and knew this before), that generally oiled mechanics are incompatible with wood dust (period), so I want them to be enclosed, so I plan to retrofit the bellows somehow. I will of course show it here if I implement a solution.
I’ve just gotten my X50 set up and running on it’s new wall mount. I chose to rotate the layout 90 degrees, knowing that this is not supported by 1F. Honestly though, the amount of dust that doesn’t accumulate on the rails is a tremendous bonus. Here’s how I modified the QCW frame to use the wall mount brackets. Basically, I bored a hole in the end plugs to bolt the hanging sprockets to the X oriented tubes. A shim is needed when reinstalling the end plug to account for play.
About the low profile clamps, here’s my version #2. The original was too tall, and I busted my dust boot , dammit! The step blocks are much stronger than bolts on the clamp bottom. The top bolts are furniture bolts from the hardware store, the T-track nuts are modified from the Oops clamps that I really didn’t like.
