Minimalistic CNC Router makes incredible parts!

[@CNCKitchen]

Too small and janky or perfect to get started and your projects?

[@robertobrenes5283]

Too small! I think a work volume of 15cmx15cmx5cm is the minimum to do some pcbs and small parts

[@mauminimus]

This is perfec for making gears into 1/24 scale rc cars, and small pcbs with smd components

[@axelSixtySix]

IMHO price decreasing CNC routers claims goes the wrong way. Should we buy a price or a proper tool ? Anyone who experienced CNC routing someday knows the goal is to get a capable machine. And the "capable" word can takes various sense from everyone. Let's propose a definition, shall we ? A capable CNC router is a machine who can get perfect results at the required machining parameters of the biggest tool the spindle can hold, on the harder material the bit itself is able to machine. Let's take as example a Genmitsu 3018. Its ER11 splindle can hold a 7mm carbide bit, so the machine should be able to take 7mm deep in aluminium at 400mm.mn. Unfortunately the machine can't hold it. This is not a capable machine. About the machine shown in your video, can it hold 3mm deep in aluminium at 300mm.mn ? Obviously not. So it's $50 wasted.

[@tinayoga8844]

I don't mind the small size. I am concerned about how fiddly it may be. (need to check into it more) I have a first starter cnc router build in progress with a machining envelope of 200mm x 300mm x 120mm . (parts stage only) It was to be a stepping stone for a later more substantial build. My starter project still will be a substantial effort. The Minimalistic CNC Router now has me rethinking my plans. Now I think I should make a small cnc router than my planned first build. Similar in design of the 3018 but with a smaller build volume of 180mm x 180mm, but more ridged, and a more accurate spindle. Or maybe a derivative of Nikodem Bartnik's original Dremel CNC project. kzbin.info/www/bejne/aGScknl3pr51prM

Back in 2009 a friend and I started to build a CNC router out of drawer rails like you did. Back then there was not a lot to build upon. We wanted to do everything ourselves. We built the stepper drivers from L293 and L298 chips. We etched our own PCBs. We programmed an Atmel microcontroller without Arduino. We learned how to create acceleration ramps for the steppers (and that we needed them!). We learned about the Bresenham algorithm to travel diagonally. We even built software to translate SVG files to something the Atmel could parse. We created our own protocol for the serial communication, ignoring the existence of gcode. We only managed a few drawings with a pen and some cuts with a Dremel. We never finished the project, but we learned a ton! We called it "Käsefräse" (cheese mill) because it was basically only capable of cutting cheese.

I had a well known company approach me about a decade ago. When I was doing a lot of engineering and machining in my business but my wife was getting into wholesale industrial scale jewelry production. They wanted me to help them develop a very very precise and expensive desktop CNC machine for jewelers and watchmakers. Something not only capable of machining stuff for Jewelry like lost wax forms and molds…. but also something capable of ridiculously tiny and precise mechanical watch parts. A buddy of mine ended up helping them develop it instead, and that little tiny thing was the size of a shoebox and cost tens of thousands of dollars. But was super impressive and there are a lot of them in use in Switzerland and other places known for small precise parts. Long story short… After being involved with that process a bit……me and my buddy both decided we could make something nearly as good and have it manufactured in Shenzhen. Since we both visited a few times a year back in those days and we can kind of watch the manufacturing process and keep tabs on everything. But you could make an insanely accurate watchmakers style tabletop machine … Capable of five axis machining of any type of material imaginable. for a surprisingly cheap amount. I can’t imagine how well and cheaply that could be done these days. Over the last decade 3-D printing and hobbyist stuff has made it unbelievably easy and cheap to tackle a project like that especially if you have a good team of guys working on it together. It’s been one of the best parts of my life getting to watch over the last 10 or 20 years… How incredibly precise and nice equipment is available on Amazon second day air mail to anyone who wants to start the Hobby. As an old timer machinist, engineer, and tool and die maker type guy… It’s just been a great thing to watch it become more readily available to everyone. Obviously China isn’t perfect but it wouldn’t have been possible without them. I hate the CCP because of how they treat their people but the Chinese people themselves… Salt of the earth type folks and then anyone hasn’t had a chance to go over there and learn a bit… I highly suggest it before spreading around ignorant BS that people always talk about and badmouth the Chinese people for. To hell with their government but the people are awesome This video is super cool because someone could develop that and take it as far as they wanted. And be able to get absolutely incredible space-age tight parts off of it if they wanted to invest a bit of time and money in rigidity

Agreed, a diy cnc, printer, lathe, band saw, or 120cm x 60cm router table is a great way to learn a lot about machining fast. I made a massive router table and it lead me down a path to learn about flat surfaces. Although not cnc there is still a lot to be learned about feed speeds and spindle speeds that are intuitively learned from manually feeding stock.

Excellent RepRap spirit, taking things back to basics....overcoming issues on a budget the reason why we have 3d printers now... I think I could build that for about $ 50, by salvaging parts and buying second hand, I don't see an issue again its overcoming issues by being creative.

[@AerialWaviator]

Like all tools, each has a set problem space where it works well, and many that it wouldn't be an ideal solution enabler. So no don't think this too janky a CNC machine. For someone wanting to learn about CNC machine fundamentals, this would be a great learning. The amount of learning provided for $50 is exceptional value. For creators making jewelry, or other smaller items this could be a pragmatic way to learn and test design ideas. Bigger is not always better.

[@reverse_engineered]

I think this is a great idea. Lots of these things could be scavenged or would be available in leftovers from another project. The main materials are available at your local hardware store - no need to buy things online and pay for shipping. The larger parts (like the rotary tool) you might already have or could be used for other things. The size might be too small for some things, but it's large enough for a lot of small, detailed pieces where that small collet and bit would make sense. You could even size it up without too much trouble. For the cost, I think it's a great platform for getting started in designing, assembling, and troubleshooting something like this. It's a much smaller investment and less dangerous than starting with larger, more expensive machines. There's also plenty of room to start upgrading it. You can use HDPE or aluminum for the frame, larger ACME lead screws and stepper motors, a proper spindle, add a small pump and some oil for lubrication and cooling, and so much more. You can do it in steps, replacing one part at a time, while maintaining a working machine. This isn't so different from the CNC mill my hackerspace first build over 10 years ago and we still use it to this day. We started with a larger frame and a trim router instead of a rotary tool, but considering the difference in scale, I think the capabilities would otherwise be quite similar. Building such a large machine required some expensive parts that weren't easy to get, whereas something smaller like this is much more approachable and obtainable. Now that I don't have a CNC mill of my own, but I do have a laser cutter and 3D printer, I'm tempted to build something along these lines. I might not go with quite as cheap of linear actuators, but otherwise it's not that different from building a small 3D printer. Thanks for the inspiration!

Now I enjoy using them. The 3d prins and cnc parts are leaps and bounds ahead of what I could do with the kits I started out with.

[@Rebar77_real]

Perfect if you need plenty of small things without tying up a larger machine. You can get flexible extensions for rotary tools. Wouldn't that solve some weight issues if you could mount the actual tool separately?

[@paulmcclay8697]

There was a "MicroMill" Kickstarter that used a rotary tool+flex shaft. (apparently links in comments look too much like spam) In this case, the other problem is that the shallow pitch lead screws chatter when loaded in the direction of motion, so the Z axis needs counterbalance to move downward even with no tool mounted. Assuming success, the next rev will lose the Z leadscrew and the whole problem will go away.

As somebody who owns both of them, the easiest workaround for the runout on the Dremel spindle is to buy a Proxxon IBS/E. Proxxons are much, much more precisely made but also more fragile.

[@paulmcclay8697]

In some parallel universe, I agree. But I tried a succession of three IBS/Es (Amazon exchanges) and gave up. The first one had small enough runout with good repeatability, which I liked, but excess axial free play. The next two had better, maybe ok, but not great axial play but poor runout. And runout+repeatability=bad. So, serious question: Has Proxxon become an empty brand now, or should I wait some time for bad stock to turn over and try again?

Since I built my 3D Prusa RepRap some 12 years ago, I haven't had any use for a mill. If I want a part in metal, I'll print it in PLA and use it as a mold to sand cast it in aluminum or brass. I agree 100%. If you wanna know something, study. If you wanna know something well, built it.

I'd like to try some casting from 3d printed positives - that actually got a boost up the list recently...

[@dekutree64]

@@paulmcclay8697 I've done a few, and failed a surprisingly large number of times even with the help of my father who did a lot of gold and silver jewelry casting in the past. Aluminum forms such a thick oxide skin, it's hard to tell if a small quantity is actually melted or not. And then if you heat it much above the melting temperature it dissolves hydrogen from the atmosphere and comes out full of little bubbles. Larger pieces without any thin sections would probably be easy though. Use natural PLA so it burns out completely and doesn't leave any pigment residue in the mold. There's no need for carefully controlled burnout temperature. My dad's old burnout oven is just a hot plate burner in an enclosure made of fire clay, no temperature control. Leave it in there until there doesn't seem to be any plastic left, and then give it another 20-30 minutes to be sure. Let the mold cool down some before pouring, else the aluminum stays liquid in there for several minutes (found out the hard way).

I would too -- that was the idea I started with. But it didn't work because shallow pitch lead screws, in some circumstances of which this is one, chatter hard when loaded in the direction of motion. If you roll the XY table on its side with the "top" axis vertical, it will easily run up but fail to move its own weight back down at any useful speed. So the XY table works only when close to horizontal. This is a problem I didn't expect and still don't see much common information about, so it's not like you overlooked something obvious.

I would love to see someone take this a bit further and invest a few hundred dollars in aluminum rails, maybe a heavy steel bed or frame. And see how rigid they can get this thing. Would be incredible in my opinion.

[@paulmcclay8697]

Agree :) ...or invest a few thousand dollars in a "PocketNC"... Also :) (would link, but apparently that looks to much like spam)

Will you make a video about the new volcano CHT nozzle?

[@user-tw2kr6hg4r]

So far I couldn't find anything about it except for the BondTech and the 3DJake site.

[@bruderdasisteinschwerermangel]

I dont think I have a use for a machine like that... But I wanna build one anyway

[@MrVivi0001]

Can this be scaled up ??

[@paulmcclay8697]

Not sure what you mean. Pretty nearly all CNC machines are bigger and stronger than this. Is there a particular feature of this design that you're asking about?

[@lastundani3348]

Review on proper printing belt extruder, when?

[@yourlocaltoad5102]

I already have a small manual mill (a Proxxon MF70) and so I might not build a cnc from the ground up, but I still intend to convert it to cnc as soon as I have the funds and figured out a way to properly control the motor speed and install a ER11 collet on it so I get get rid of the Proxxon-specific collet system. If everything works out as I hope it does, I should be able to machine steel with it and I really wanna develop my own direct drive system and Hotend for my Ender 3, so the ability to machine steel and other metals will be quite useful. It would be really cool if you could do a video that’s a introduction to diy cnc mills covering the basics of a motion system, what’s needed to control it and some of the software behind it, as that’s something that I haven’t yet been able to find a good KZbin video on. And having a good video is always nicer than having to read a bunch of blogs and websites (with half of them only mentioning things they can sell via amazon) to get a basic grasp on a topic.

[@naren4wood560]

hey hey, im also intrested in cncing, but the biggest prob i run in is the electrics, im a bit scared when it comes to the buy and put together part of the electronics, so maybe you can recoment me someone that shows what to buy how to cable and how to intall in aclear and easy way? thx for the great videos, im going to start 3d printing also when my new 3d printer comes :D

Up next, overclock your $1 laser pointer into a laser cutter 🤯

[@jonathanvoshell7914]

Honestly, the Coding of this is the only thing that peaks my interest.

[@Crushonius]

i like this project and he is a cool dude no doubt and ten years ago man this would have been such a useful cool project . but its 2022 and if you factor in the cost of the dremel you almost are at the price of a 3018 genmitsu or even cheaper a clone of it i found some on german amazon for around 165 its a sore dick deal you cant beat it

[@paulmcclay8697]

:) I haven't seen comparable precision from a 3018-type machine. And a rotary tool is a general purpose item that can earn it's own keep, no?

[@Crushonius]

@@paulmcclay8697 i am not sure which 3018 you have used or seen in real life but i can at least talk for the genmitsu and it can easily be as precise as this diy CNC . With a little bit of tweaking it will downright outperform it

[@paulmcclay8697]

@@Crushonius Apparently replies here can't mention even an obfuscated pointer to other content, which makes it harder to answer directly. When I looked for examples of fine pitch circuit board milling with 3018-type machines, the cleanest example I found was an SO-pitch breakout board. That, and a couple of functional but rough examples of 0.5mm pitch were the best I found. Please send better examples of fine circuit milling or other work at similar scale, for more valid comparison!

[@gizmobowen]

He wasn't that the dude from Proper Printing looking at this CNC in the beginning?

[@CNCKitchen]

Yeees, that was Jón! He accompanied me on the trip to MRRF.
