Contain the metal chips and coolant 💦 with a custom enclosure

This project started with a relatively simple goal: enclose my DIY CNC mill to prevent metal shavings from flying all over my garage. However, I decided that if I was going to build an enclosure then it must support flood coolant for improved surface finish of machined parts and increased tool life. Of course, this requirement led me down a rabbit hole as I designed, plasma cut, welded, machined, and even large format 3D printed components for a project that quickly grew in complexity. The complete build took about 5 months of weekends, but all this work resulted in what I believe to be one of my most entertaining videos to date. Further, improvements in quality of life (no more spending hours cleaning up after milling) and surface finish of parts has made this investment of time and money worth it. So worth it that I thought everyone should have access to my design to build their own enclosure. Find my free parametric model on my website: drdflo.com/CNC...
This video also features several upgrades to my mill, including double nut ball screws, variable lubrication system, and new spindle bearings.

This is such such an awesome build, but please be mindful when welding around pets and other people. Even indirect exposure to the welding arc (reflections) can cause eye injury. "Arc eye" is basically UV "sunburn" damage to the retina. While this heals in a couple of days, reoccurring exposure to extreme UV (e.g. from an arc flash) over time can lead to permanent eye damage and blindness. It's hard for our dogs to tell us they're having trouble seeing. Even if your dog wants to stay close, it's important to keep them away and safe.

That is mighty impressive, I never expected the spindle to become so much cooler after the modification. But you should really use a proper respirator when working with epoxy, especially epoxy based spray paint. Even short exposure can be very harmful.

Hey David! Your builds are always very impressive and this one is no exception. The pillowing you’re seeing on the print is due to there not being enough top layers. Some things you can do to improve this aside from more top layers is higher bridging/solid infill speed and more part cooling.

@3xtrusi0n Жыл бұрын

Isn't it mostly speed/part cooling related? Not that I've worked at such scales before, at all, but I have noticed going fast with inadequate cooling leads to 'top' fill layers to 'stretch' apart when there's uneven cooling from the top/bottom (the temp is removed faster from the top, since uninsulated). This causes them to curl upwards. More top layers feels like a patch to the actual issue. Could be entirely wrong though, appreciate anyone's insight here.

@saf3ty3rd Жыл бұрын

This is really difficult with sla/msla/dlp because the membrane in the vat becomes more flexible as the area scales and the total adhesion force goes up. This is probably why the formlabs print "head" actually pushes up on the bottom of the vat in the area being scanned.

@DrDFlo Жыл бұрын

Joshua is right. You actually have to flip the process over (see the ProX 950: kzfaq.info/get/bejne/sJddhbyDt9XUqGw.html ) You then have to have a really large resin vat, which would cost several thousands just to fill! Also surface tension leads to poorer print quality.

On my mill, I put the Y motor on the back side behind the column. I did not like leaning so far into the mill during setup operations. I used a 3d printed adaptor to match the draft angles on the casting so I could mount the y motor correctly. After a couple of years of use the 3D-printed adaptor broke down and crumbled. Your drawer may experience the same failure being exposed to coolant. It might be something to keep an eye on. Overall I love your enclosure. It turned out great!

Maybe this is the sort of question you're not supposed to ask, but I have to ask - where do you get the money for projects like this? Of course this is done on a budget, but knowing how much this sort of thing tends to cost, that budget can't be small. Like I work a relatively decent engineering job and there's no way I could afford all that hardware without saving for... years probably. And that's without spending on any other projects. All the same, money doesn't make you good at designing and building CNC machines, and this is a very well-executed build and well-produced video. Great job. :)

@DrDFlo Жыл бұрын

Some of my projects, like the Large Format 3D Printer, are sponsored, but even when I receive some the big items at cost or free, the small hardware and the other bits and pieces that you don't think about have started to add up. Over the last two years almost all supplies have doubled in cost. A MeanWell 24V power supply now costs $40-$50 when it was $20 about two years ago. Same with stock aluminum or plastic material. The point of my rambling is to say that it is getting difficult to afford these large projects.
