Nikodem Bartnik - well deserved mate, you were never crap, but you’ve improved exponentially over time and this last one was just great😎

[@TheRainHarvester]

If you take a 2 liter soda bottle, you can cut it in one long strip by using a spiral cut. I make very long pieces of clear plastic this way. Just keep to the portion of the bottle that has no curves. The spiral cut might actually benefit the ball screw cover, because it needs a little spiral anyway. No glue joints!

[@haenselundgretel654]

Hello. I'm a 35 year old graduated engineer and admire and appreciate your work! Congrats mate! You're great! This video is not just funny but also intelligent. Nice.

[@kurtlindner]

This was hilarious. "...even the second page of Google search." lol

[@0lympy]

Excellent presentation, Niko! Keep goin' on

[@DanBader]

If you want to go one step further, you could add an air line to provide a tiny bit of pressure inside the shroud to further 'encourage' the dust to stay out.

[@nikodembartnik]

Cool idea! Never thought about that. It would be like a positive pressure suit for ball screws :)

[@aarondcmedia9585]

Was thinking the same thing. It's like positive pressure in a PC cooling setup.

[@marcoguandalini5743]

You could look into those plastic hoses with metal rings inside and see if they work, I'm not sure there are any in the right diameter though. I don't think they will offer a lot of resistance to the advancements of the x, y, z axis and the idea of the air is also a very good one.

i saw exactly similar scene in cnc video by someone else, but i can not remember who

[@jamescullins2709]

Your are a brilliant young man, I really like your design of the gantry of you CNC Router. Keep it up.

[@victorandrei02]

If you want a good way to join the PVC strips together, you can use a blowtorch to melt one face on each of the two ends that you want to join, and then stick them together with the melted faces touching each other (maybe 2 or 3 cm of overlap) and clamp them between two pieces of clean scrap metal (vises are good for this). After cutting off the excess plastic that flowed out the sides of the strip, you should have a pretty solid connection. Great video!

[@BBru062]

You could probably use some shim stock for this, they sell it by the roll too.

[@per.kallberg]

That’s how it made commercially

[@justgotravel6646]

Did you test that small articles, like saw dust does not going to block the friction of the tube over time?

[@evren.builds]

I also want my own CNCologist. You're very lucky to have one :) Edit: For some reason youtube doesn't show my other comment. I will add it here. What about using one of those extendable steel staffs?

[@nikodembartnik]

Cool dude, he just complains a bit too often

[@MarinusMakesStuff]

Limit switches can be replaced with TMC2209 drivers these days, they have Stalguard built in ;) And normally we use bellows around our linear systems to keep everything clean. I really like the telescopic idea, but for me bellows work really well and are affordable if you find the right supplier. Now what I want to add, old bellows were sometimes made with some very smooth and strong (200grams) black paper backing and overlayed with some sort of fabric. This causes the inside to be smooth and the outside to be tear-resistant because of the fabric. The benefit of bellows is that it really doesn't let any dust through, whereas the telescopic solution will collect dust in-between the paper layers and eventually it can get either stuck, or will keep dust inside of the telescopic tube instead of keeping it out. I suggest using a fabric 'sock' over the telescoping tube will keep dust out. This could be a great addition to your design.

[@justgotravel6646]

Fabric sock sounds easier.

[@MarinusMakesStuff]

@@justgotravel6646 I think the sock needs a medium in order to keep it from getting into the mechanical parts. So the telescope is ideal for that.

[@justgotravel6646]

@@MarinusMakesStuff i was commenting on the dust coming into the telescope tybe when i saw your comment. What about just a plastic bag tube with thin Steel Wires to keep it's round shape. Or make it as a shower curtain with a bar holding the Steel Wires.

[@justgotravel6646]

Btw the tmc driver you talk about is that the one that detect friction / stop on the motor.

[@MarinusMakesStuff]

@@justgotravel6646 Oh yeah that sounds totally cool, a plastic-bag-tube kind of design with a thin wire spiral made or spring steel would work nicely as well! I like the idea.

[@PhG1961]

Nice sense of humor ! Also an excellent product/solution ! Well done !

[@blanksender7808]

You've got a hell of a career as an engineer ahead of you. I don't know if you're going electrical or mechanical but either one will suit you well.

[@misamokuzelpizu]

i wonder if you could 3d print cover spirals out of e semi-flexible filament and use only one layer thick walls.. or maybe even 3d printed segments

[@MP-mu1kw]

Excellent video! Keep tinkering with different ideas and things and never give up! I am still a newby and trying to figure out the CNC basics with my low cost cnc 3018. It is only a matter of time and will be building the IndyMill as my next CNC upgrade.

[@jappiemoto]

That’s a super cool design

[@Lozoot2]

This is an awesome solution, but did you consider the design of shock absorber boots? They sort of "accordion" in and out, they'd be perfect for this application!

[@glrider100]

Regarding the ball screw covers. This would cause your X axis to be longer but.... instead of the ball screws on the outside of the X gantry supports, put it on the inside. Then, on the top of the Y rail and linear rail/bearing assembly, you can add a simple flat piece of aluminum that "almost" touches the X gantry. This would shield the rails and the the ball screw. Also, it would be a nice place for the wire chain to rest. Again, it would cause the X gantry pieces to be longer.

[@solom57in1983]

i think if we put small brush in front the nut and fix it with 3d printer holder can work also

[@djcishere]

The Pvc is a great idea! Would suggest some ptfe spray as a bit of a dry lubricant to help decrease the sticktion. Also, you could like at teflon cooking sheets as well, over the distance, im not sure about rigidity, but with enough winds, I reckon you could be getting closer. Keep up the good work, cant wait for you to get closer to end game, as I will be certainly building one of these. Really appreciate your smarts!

[@PaulSmith-gt2lm]

Loving the upgrades and video format. My laser cut parts arrived yesterday and I will be building my indymill soon. Hopping to record build process. I hope you can share your limit switch additions in another awesome video.

[@eugenes9751]

If you add air valves to the covers and provide a little bit of positive pressure, it'll keep the smaller dust pieces from going in between the layers.

[@photoswisscore]

Andr for linear rails ? I looks to protect linear rails and not axis for my futur project

[@justoneofthesheep]

[@MrStrizver]

There are plastic fluorescent tube covers that are very long. Perhaps a spiral cut on one of these could yield two shields that are one continuous piece?

[@lazyh-online4839]

A suggestion for connecting the plastic strips, there's ultrasonic welders for plastic that should work well, and once you start using them you'll find all sorts of uses for them.

[@karipenttila2655]

Nice dialog from Bart to Bart. But why you not do like I did, I designed a sponge holder that is oiled and cleans the debris, both ball screw and linear rails. Naturally you need clean those sponges every so often but, they lubricate and keep debris out of getting in into bearings. In addition I have chip cover to direct most of the chips on y direction both sides.

[@PTJeff9x]

What are the travel maximums for each axis? Given the rails that you used in your project. I have not seen any in the videos. This looks to be the perfect size for my guitar project

That was a pretty funny video! And really like that you're experimenting with your content!

[@haenselundgretel654]

You'll have to enclose your linear bearings as well! Try to have a complete and a moving cover for both between your milling volume and the bearings and ball screws. I use a side cover for 80% of the dust and a driven rubber cover around the moving parts

[@adsonvital8477]

[@nikodembartnik]

[@andrewwakefield4519]

Nicely done video, and you've got me thinking about possible designs...

[@paskmoe4969]

how about building the cover "bandsander style" .....the moving "sandpaper" as cover attached to the gantry..it only would need a sider cover and 1 rolls at each end. The moving part could be some kind of cheap pont foil. If there is enough "overhang" from the foil this might work.

[@andersstromqvist2211]

This works the ball screws but you need to protect the linear rails to. Bellows are not that hard to fold from paper or plastic and then you can make them big enough to cover booth the rails and ballscrew. Perfect cheap diy

[@matthewsimmons6831]

The couch-and-doctor style worked really well dude. I'm sure a fan could suggest a good lubricant to help keep the roll slipping without jamming up; maybe silicon based?

[@GGGG_3333]

You should check out fork gaiters, like the kind used on Motorcycles. They're super super cheap, durable and work really well for covering leadscrews!

[@antoninperbosc1532]

Congratulation this a very clever solution ! can i suggest you to add a flexible pipe who add a positive pressure with deshydrate oiled air and distributed it with a micro lubrication your screws will last for years. Make bellows to protect the slide the slider hates dust and add the same technique as above !

You could try aluminium flashing as it is pretty widely available, not sure how it would perform though... Might be too maliable

[@SianaGearz]

Not bad. My first inclination would be to use polypropylene sheets, like from a folder, but there's one problem with them... you just can't glue this material, at all. PVC is a good solution and i think contact glue should work perfectly with it.

[@canonokintama]

Gread video. Have you considered making those covers using origami accordion patterns? If you search for "origami bellows" you may find another solution to your problem at least for the z axis.

[@nikodembartnik]

yes I did, but my origami skills said no

[@andersstromqvist2211]

@@nikodembartnik dont give up mine was horrible but after trying a few times i got them working if you scratch out the fold patterns it works great.

​@@nikodembartnik you can learn basic folding skills following simple origami tutorials. I recommend tadashi mori's channel. I hope your origami skills change their mind:)

[@seppei7955]

First of all great Project. And I have a question on that. Which CAD program are you useing?

[@RuudCreates]

Nice video, always nice to find people I've seen for ages on Instructables also here on youtube. As for an alternative solution, maybe you should take a look at origami bellows. I think that if you would print those in a flexible filament it would be ideal for covering your ball-screws.

[@filopat67]

Offset printing plates might work perfectly in this application, they are made with very thin and springy aluminium. The problem may be where you can find them in this age of digital printing.

[@b5a5m5]

Instead of joining PVC sheets together with hot glue, you should try taking a large soda bottle and cutting it into a very long 40mm strip. If one bottle's worth of strip isn't long enough I believe you could also clamp 2 strips together with some blocks of metal and slowly heat the metal block up to fuse them together in a seamless fashion. You can use some spacers of the correct thickness (perhaps metal feeler gauges) between the two clamping surfaces to make it so when the strips melt together the clamping force doesn't just squish them very thin and it will make sure the seam is of a uniform thickness. Maybe some wax paper on both sides of the strip to act as a release (kinda like fuse-beads when I was a kid.) Oh, fuse beads... Use a clothes iron as your slowly heating metal surface 😃

[@b5a5m5]

Did some math, the 2L soda bottles here in the US are ~105mm in diameter and the usable middle cylindrical section is ~150mm tall. So let's say we basically have a cylinder with 325mm circumference and 150mm tall. If we slice that into a spiral where the spiral strip is 40mm, wide out of one bottle we can get ~895mm of 40mm wide strip; for us US peeps that's just about 3ft.

[@klausbrinck2137]

"You used hotglue, seriously now? What´s next? Are you gonna start making life-hack-videos???" ;-)

[@MisterMakerNL]

This is very cool idea! But don't use air pressure to clean!

[@DanBader]

Yup, use a vacuum instead. Blasting it with an air gun will just drive the dust in

[@eliblessed]

Love the video! Have you thought about adding a small diode laser to the mill? that would make it do double duty, and for people without a laser, would mean that they could do engraving and cardboard/paper cutting. No idea how it would be wired, but it is an idea...

[@johannprum6393]

excuse me where is the videos of your tool used at 8min38 of your videos.

Use a plastic shower curtain rod cover which has a slit in it .cut the proper length for the ball Screw. slip it over the ball screw through the slit and just let it hang there . there's your dust cover

😳 I looked also at page number 5 .... and now I'm looking at myself as a monster 😭😭😭

[@partytempo]

This is gonna sound really boring, but here's an alternate design. Instead of the telescoping cover, just encase each side in a "box" and cut a slit along the top long edge for the Y-axis vertical arm to pass through. To keep a primitive seal on the slit opening, use bristles. They move aside when the veritical arm passes through, but form a seal to keep chips out.

It seems like sawdust would settle on the fibers, then fall in as the gantry moves them apart.
