This is one of the best custom built CNC i have seen on UA-cam. Most of them are made by people with huge experience in mechanics, tons of tools and another lathe or router. Thing is that people watching those videos don't have either experience, nor tools, and definetly lathe, so Your video is very helpful and inspiring.
First thought @0:10 : "What a piece of crap!!" Second thought @ 2:00 : "Y'know.. you could learn a lot from this project, and not spend a lot of money" Third thought @ 3:00 : "Well, shoot. Why didn't I think of doing this earlier?!!? What is there to lose?" Hats off to you!
THE ORIGINAL .... www.buildyourcnc.com Start small, low tolerance... AND LEARN WHY EVERYTHING IS AS IT IS. DOING, NOT GUESSING. MAKE MISTAKES, TO LEARN FROM.
Five years ago I had the same plan, building a cnc router. I wanted to incorporate parts from old printers etc. but I realised soon enough it would be too big a challenge to fit all these parts together and have a rigid and accurate machine. So I decided to design my own cnc router. Therefor I had to buy some tools and use the expertise of a colleague at work to fabricate one or two parts. The rest I did by myself. The build took four years, it seemed like forever, but the ton of experience I got is priceless. Nice videos Stefan! Keep posting.
Michiel van Hees can somebody make his 3d printer 👉 a car key cutter/engraver ? (notice it has to precisly make the cuts on the blank new key which has a small area)
I'm used to larger, corded routers ua-cam.com/users/postUgkxfQ5_mgwq6PcudJvAH25t-I4D-3cTPz4z so this was a different experience for me. Basically, this is an incredibly sweet machine, fits well in the hand, etc. It has slightly less power than I'm used to, but that's understandable. Maneuvering freehand takes some practice. These days, it's especially nice to be able to avoid power cords. This is above the level of a hobbyist but below a pro level.
@CNC Kitchen Hey! Just wanted to thank you, saw your video over a year ago with this machine in it, and decided to build my own. The first one was kinda bad, but it worked, currently testing the second iteration, and it works great. Chinese router, with box section frame, metric threads, and a with a workspace of 320x250x60. Interestingly mine also looses steps, with specific feeds. It was a nightmare to debug, but I think I finally got it working. Tried the drawer sliders, but they got real bad deflection, currently using 3d printer bearings for small loads, and a combination of 608 bearings on an aluminium profile for high loads.Works great. Thanks for your work.Great video, as always.
Wow i always thought i was to much of a perfectionist to use wood and drawer rails. You have proved me wrong and you were able to learn a lot quicker than me!
I made a wood CNC machine as well, it was my very first electronics build. I LOVE your design, especially the use of the joist hanger for mounting the router.
Fantastic!! I want to do the exact same thing right now! Thanks for inspiration, I would have never thought about using wood. And I can use wood easily so once again 👍👍👍👍
Wow! Tastefully done! I was just in the process of making my own DIY CNC router out of parts scrounged from my garage, the backyard, a junk bin full of stuff that maybe would come in handy someday, like IKEA bed frame birch plywood that was up in the attic for decades! And old drawer glides! I was going to buy a really good one for about $500 but my wife convinced me to try and do it myself. I actually like making tools better than using them to make stuff.
Fantastic video in every point of view, the speech, the voice, and the video quality awesome, informative, short, and sharp enough. All together a perfect example for how-to-create an educational video. Congrats, and thank you!
wow, didn't expect to see cnc made out of wood, it's relatable to not have metalworking toolset and needing a cnc too much! i think i gotta repeat this project next month! thanks for sharing!
Huh, I never thought to use drawer slides for the moving axes of the cnc. I might actually try this since I have a bunch of drawer slides like these and plenty of leftover plywood from other projects =)
Nice Machine ;-) My router also started with a Proxxon "Dremel", and is waiting for the 2kw water cooled spindel for some years now... Fortunately i started with NEMA 23 Steppers.
I used those springy aluminum axle couplers, but I noticed they bounce during fast moves. I ended up using fuel line (with wire twisted to hold them tight). I made a video on my channel.
Excellent build guide from the bottom up with limited tools and materials. The follow up retrospect advice was really helpful. For a startup on a limited budget and space, its inspiring . Thanks
Richtig cool diese CNC - du müsstest eine kleine Projekt Serie machen, in der du, eine 2.0 CNC Kitchen CNC baust - mit deinen Erkenntnissen aus der Vergangenheit. :-)
I made a 4ftx6ft version of this from plans I bought online back in 2004. It used 1.5"x3.5" (2x4) lumber from Home Depot which I sealed with a polyurethane varnish. I used NEMA 23, 1/4" adjustable hand router, 30V 200W supply and 100W current chopping stepper drivers from China for $50 each. All was run on a parallel port of an old 286 PC saved from landfill, running DOS 6.22 and TurboCNC sw. I wrote my own gcode by hand to cut my kitchen cabinet doors. After I was done with it, I sold it for $750. It costed me around $300 to build it.
The drawer slides are an interesting idea, never thought of that! I'm always amazed how cheap you can build these while still getting good results. My first CNC Router was also built from plywood parts, although I used ACME leadscrews and SBR16 linear rails. Overall way more expensive, I paid around 500€ for the whole machine including electronics, motors and spindle. It did a great job though! After a while I machined aluminium parts for a new Router, this time with a VFD Spindle, full aluminium construction and ball screws. Only thing I'd change would be using hybrid steppers or Servo motors, at least for the Y motors (which move the whole gantry). The steppers reach their limits fairly quickly there at around 3000mm/min.
The speed limitation might be due to the drivers or the voltage. I went from ~4m/min on 24V to ~7.5m/min at 48V. Also, my DM556 drivers reach a lot more rpm than my TB6600 drivers
What I think of this project?! Absolutely amazing is what I think! I've been feeling so much like going into CNC after year and half on 3D printing. Let's see if that happens by Christmas! Cheers Stefan!
It's funny that you post this now, I've just finished a similar thing (with more scrapyard bits). Only difference is, I have used the very cheap slides that you've decided against. I set them up as dual and inverted to gain stability, but they remain really wangy. On inital feel the slides alone feel quite positive, but in fact the balls have a lot of play which is only taken up by the flex of the plastic carrier. Your machining results look significantly better already, I would think thes bigger slides actually do better. It would be interesting to know a sitffness value of yours.. am planning to measure mine soon just for the giggles. The frame itself isn't the problem, so In any case thats some actual rails for me, soon.. Cool budget build, loved to see there are other people with a similar approach to getting started :) Usually you get the "ah that's crap, don't bother until you spend that X amount of money.." feedback..
computername I wonder how your slides would have done if you had tuned them per Matthias Wandel's instructions as he did when making his slot mortising machine? He sort of makes them into industrial slides. I am going with aluminum rails and V groove bearings for my first iteration of a wooden CNC.
@@terry2346 Thanks for the suggestion. Had a a look at them and it looks like, in comparison to the ones Matthias and Stefan have used, the V-groove isn't very pronounced on the cheap ones. So basically, if you bend them tighter there might be a chance the balls snap out of the rail completely and they don't work anymore. I will give it a try.
@Terry Got round to tweak the slies accoring to Matthias Wandels method. It did indeed increase the stiffness but they still flex. I think it's the metal itself bending under load. I stiffened the whole machine with struts and tried with different feeds and speeds and eventually got more useful cuts, I think the strategy + settings make a big difference. Here on youtube people managed to cut aluminium with an MPCNC, that shouldn't be miles off in terms of stiffness, one of them suggested that adaptive (?) toolpaths are key, so gotta try with them to see if there are further improvements. I also think a more suitable spindle would make a difference as I am still using an old corded drill that has quite low rpm. After watching some other videos I'd say it's now probably as good or even slightly better than these plastic mini-routers from ebay. It was definitely way cheaper than these so overall a nice learning project. Probably way better with the aluminium rails you suggest.
If you are trying to align holes for the rods to pass through the bearings, I would clamp the two boards together and drill pilot holes through both. It takes a little pre-planing before assembly
This is awesome. I am looking to build my own CNC router and while I'm not going to use your design, you did mention several things that will help mine. Thank you.
I like it a lot. Here, such ingenuity is considered awesome, the basis of who we are. Well done. It is not what you have, but what you can do with what you have that is important.
Aluminum is very easy to weld with just a propane or mapp torch and aluminum brazing sticks. An hour or two of practicing, and you'll be ready to build anything.
"...wooden stand-offs, which I thought were temporary at first, but in the end, worked out pretty well." Every project of mine ever has had at least two cases of this exactly. lol
If you want good quality stepper motors for little or no money, find a photocopier shop in your area. They are constantly discarding obsolete copiers and very likely would be happy to let you take a junker for free or a small fee. The document feeders (The unit that feeds stacks of paper one at a time to be copied) usually have 2 or 3 NEMA 23 steppers in there, the body has more running various other drives.
You know you have an engineer in front you..when he says.. "I should have painted it...(pause)..cz humidity and steardyness... " And you realize that unimportant skrews are both pan head and dive skrews.. heck the head does nothing for the pull force... Thanks Stefan. - great vid... I am sticking around..
Could you oil the wood and make it less moisture sensitive? Some truck bed liner might make it nearly indestructible (kidding, but only partially kidding.) Maybe an aluminum bed material for adding that laser? I like the ball screw idea. Did you mention linear rails? I might have missed it. Would be neat to see more information on how you got everything aligned, trammed, plumb... Etc.
for the torque problem , a simple gearbox could solve the issue (since speed is never maxed out) 1: 2-5 could be done with just 2 gears (aviable in china for ~2$ a piece)
This is the first cnc I've seen that raises the entire x axis for z moves. It may even be more stable with regard to z sagging /tilting out of straight up and down.
This is absolutely great! Creating a useful machine with what you have! I hope you save this machine as part of your history and evolution as a mechanical engineer! Thank you for posting this!
Thanks for sharing. I was looking for an affordable CNC but this is actually way more fun and reward than any prebuilt. On top of huge savings of course. If you don't mind me asking, what engineering studies did you do?
It's a great project. I have just got to get down to construction. I have the electronics, bearings and motors and threaded rods. I have a tinyG and am going to do Chilipeppr. My biggest problem is that I want to make a big machine but only have small motors. So your setup is the most realistic. Thanks for the inspiration and as always, excellent video.
Möjn,möjn.. I think you've done some good work with this one. Thanks for sharing the ideas and your thoughts about how to improve the machine. I'm in the progress of building one myself. Guess it will be a long and cumbersome way. However, you showed me it can be done without expensive materials.
Thanks - proof of concept. If I build one, I will fibreglass the individual pieces to protect and increase rigidity. I wonder if any of your viewers have built one and used fibreglass external skin?
I encountered the same thing with the drivers and switched to DRV8825 as wel. Now, they have polulu drivers , producing 4A , definately a good idea. I used Nema17 High torgue steppers for my 3D printer, but it can also do a bit of milling. I started with TR12x3 , but it is more advisable to use a pitch of 1,2 or 4, because of the 200steps and 16/32 microsteps. With a 200 steps/rev and 2 pitch, you get 0.01mm per step, a nice round number. This means, the stepper coils get fully charged/discharged. With 3mm pitch, you never end up with maximum holding torgue and the 'steps_per_unit' settings are not a round number. I now used the tr8x8 (8mm pitch) to speed up the 3D printer. It is the same with ball screws. I use 2004 (20mm with 4mm pitch), but they usually sell 2005.
I was planning my own CNC machine back in school. Back then we hadnt had such a broad software base to choose from as right now. Thats why I gave up because 14 y.o. me wasnt able to understand half of what the make shift software avaiable to makers requirred to know. Now I feel like the bug bit me again and maybe I will get out my old plans and revisit the idea...
Mister sorry for my langage but i'm french : You have my totally respect realy !!! Bravo Monsieur Your mind is very accuracy realy !!! thank for your ideas ... I'm very exiting about your chanel Long life for you . Eric Bergart Isigny sur Mer in France
I started with wood, and normal m8 threads and nema17 motors, but realized wood wouldn't be stable for long time. Just started a new project with only Steel and Aluminum nema23's T3x6 threads and 1.5kw spindel. Cant wait till finish
Damn, throwing shade us mechanical engineers at the beginning 😂, I'm learning electrical engineering as a hobby bro, recently got an alduino and planning linking the two fields together to make my own DIY projects. Can't we all just get along 😭 . Thanks for the tutorial btw keep it up
AWESOME, I kinda did the same thing, except for the X,Y,Z I used 8mm rods with linear bearings and epoxy'd them to the mounts with J-B Weld. I enjoyed your video and Makers Make the world!
Have you considered making a video where you test the multiple extremely cheap linear rails available online? I ordered some from ali and while i don't really know how good or bad they are they seem to work well enough for 3d printing and i'm wondering how they compare to quality rails.
why is it no one has ever as far as I know tapped the end of a shaft coupler so you can screw in the leadscrews then use the grub screw to tighten. This would eliminated grinding the leadscrew. I think your machine is a 10/10 for KISS design and will help beginers understand the machine better than just paying for one.
I know a commercial sign maker in the Los Angeles area that has router tables built on the same principle as this machine shown here in the video. Just because this is a very small machine, it does not take too much to use larger motors and larger stepper drives to make something that is even 8ft by 12ft or more in size. The most difficult thing with any machine is keeping the waste out of the electronics and making good use of the software, as some software programs are even too much of a headache to use if they are free. One good start is using Mach3 or other similar software, as interface boards are for the most part quite affordable. I have designed and built many machines and have upgraded and repaired many more, but I'm a much better consultant at this point in my life due to spinal problems and other medical problems that limit my ability to do physical work. If anyone near the Southern California area wants help with some ideas, perhaps you could contact me. I am glad for Stefan and others as they show things from a hobbyist side that I have never really given much thought to. As I would not consider building a machine out of WOOD, but others have and they have earned many thousands off of their work. The key thing with any design is not that you are interested in a machine, but what is the primary thing that you will use the machine for. If you are welding or using lasers, wood and many plastics are out of question, but if using it as a router for plastic anything even particle board is good for the body of the machine. Also if someone wants to hold a sheet in place for machining, a vacuum cleaner can be used as a source of vacuum to hold it in place. Key thing is what are you cutting, how accurate, and speed of construction, ability to modify for other things, and so forth. Just because some company makes a machine for many millions, does not mean someone else can't do the same for a couple of thousand or less. Be creative, and if not sure ask others what they think. There is an old saying that no man is an island... This is for the most part true, as one person can't do everything, as the most basic things will keep you from being creative, but with others we can come up with and create things that few if any thought even possible. I've been an engineer for a few decades, and sometimes it is quite profitable, but many times it is a struggle just to have money to put fuel in the vehicle, have food to eat and keep the lights on etc. Do things because you enjoy them, because if you do thing just to try to earn money you will be hurting. There are many things in business that take far less thinking and have much better rewards than being creative in this world.
Great video. Perhaps I will build a cnc in the future as well. Your project showed a good starting point and gave good advices how it can be done in a cheap and easy way. Keep going on. 👍
wow, interesting that you get by without thrust bearings on the lead screws and flexible alu couplings :O 608 bearings really are not made to take lateral force but seems to be sufficiently sturdy :)
Well son, you want to know what I think about your project so here goes; I think it's genius in the fact that you started out simple, the way every endeavor should. Everyone now days has become so price concise they have forgotten what it's like when your parents aren't supporting all your, what may seem like hair brained schemes. This is where new technology starts!!!
Hey Stefan, super, dass du das Projekt so durchgezogen hast! :-) Ich hatte vor 10 Jahren (glaub 2008 war das?) auch schon die Idee, eine CNC-Fräse zu basteln, hatte sogar schon ein Design fertig und wollte auch Schubladenschienen verwenden, allerdings 2 Paar pro Achse, jeweils um 90° angewinkelt. Erzählt doch mal wie viel mm/min bei welcher Zustellung du in verschiedenen Materialien schaffst, so dass die Fräser heile bleiben und das Ergebnis noch genau wird. Da ich mein Projekt damals nie zuende geführt habe interessiert mich natürlich brennend, was da so gegangen wäre. Fräst du auch Aluminium damit? Ich habe mir gerade aus China so eine 2418 CNC Fräse zum Platinenfräsen besorgt. Die ist komplett aus Aluminium mit Rundwellen als Linearführung. Die hat schon ganz schön zu kämpfen bei nur wenig Zustellung in Holz (0,5mm Zustellung, 100mm/min, 1.5mm Diamantverzahnter Fräser), bringt dafür aber auch ziemlich genauge Ergebnisse. Die Kräfte, die da auftreten, scheinen doch ziemlich immens zu sien.

you are the best I found so far man! keep up the good work!
Could you oil the wood and make it less moisture sensitive? Some truck bed liner might make it nearly indestructible (kidding, but only partially kidding.)
Maybe an aluminum bed material for adding that laser?
I like the ball screw idea. Did you mention linear rails? I might have missed it.
Would be neat to see more information on how you got everything aligned, trammed, plumb... Etc.
i love your style - open mind is great - your english is super - your future is paved with awesome things
for the torque problem , a simple gearbox could solve the issue (since speed is never maxed out)
1: 2-5 could be done with just 2 gears (aviable in china for ~2$ a piece)
Cool project. Im considering building a wood cnc. Youve Given me quite a few ideas to play with.
What a cool project!
I was looking at drawer slides at the hardware store yesterday and contemplated this same idea! I didnt think it would work, touche'
Top vid fella keep on making them 👍
Duuude.. That thing is Baaaad Assss!!!
Makes for a nice entry point into CNC. THANKS.
I like how the gantry moves for the z axis
This is the first cnc I've seen that raises the entire x axis for z moves. It may even be more stable with regard to z sagging /tilting out of straight up and down.
this seems really good I'm looking to make a budget one just for fun over the new year and this seams like a great place to start
This is absolutely great! Creating a useful machine with what you have! I hope you save this machine as part of your history and evolution as a mechanical engineer! Thank you for posting this!
I have the same concern regarding adding a laser...But so tempting! Subscribed!
That Z axis was something I've never thought about. smort :)
I think you did a great on your build for your first cnc. Most people just dream about doing it (like me).
Interesting, affordable and useful ccn DIY project. I would like to built one.
Good project and excellent explain.
Another plus in making it out of wood is that it sounds really cool when operating because the frame behaves like a soundboard for the steppers lol.
Dank. I wish I can like you once every time you have a good idea. Maybe UA-cam should allow us to rate, instead of just thumb up.
Nice piece Stefan.
Thanks for sharing. I was looking for an affordable CNC but this is actually way more fun and reward than any prebuilt. On top of huge savings of course.
If you don't mind me asking, what engineering studies did you do?
Ich habe mir auch eine CNC fräse gebaut ;D Es ist echt krass das du das mit so wenig geld geschafft hast solche guten Ergebnisse zu erhalten
Excellent! Inspirational!
It's a great project. I have just got to get down to construction. I have the electronics, bearings and motors and threaded rods. I have a tinyG and am going to do Chilipeppr. My biggest problem is that I want to make a big machine but only have small motors. So your setup is the most realistic. Thanks for the inspiration and as always, excellent video.
Nema17 will work if you don't go too fast. Mine worked for 5 years. Better try, fail and learn instead of hesitate and do nothing at all in the end.
Möjn,möjn..
I think you've done some good work with this one. Thanks for sharing the ideas and your thoughts about how to improve the machine. I'm in the progress of building one myself.
Guess it will be a long and cumbersome way. However, you showed me it can be done without expensive materials.
Thanks - proof of concept. If I build one, I will fibreglass the individual pieces to protect and increase rigidity. I wonder if any of your viewers have built one and used fibreglass external skin?
Very good project
I encountered the same thing with the drivers and switched to DRV8825 as wel.
Now, they have polulu drivers , producing 4A , definately a good idea.
I used Nema17 High torgue steppers for my 3D printer, but it can also do
a bit of milling. I started with TR12x3 , but it is more advisable to
use a pitch of 1,2 or 4, because of the 200steps and 16/32 microsteps.
With a 200 steps/rev and 2 pitch, you get 0.01mm per step, a nice round number.
This means, the stepper coils get fully charged/discharged.
With 3mm pitch, you never end up with maximum holding torgue
and the 'steps_per_unit' settings are not a round number.
I now used the tr8x8 (8mm pitch) to speed up the 3D printer.
It is the same with ball screws. I use 2004 (20mm with 4mm pitch), but they
usually sell 2005.
cnc minimum motor what can use good have only nema 23, not ever nema 17 have good or working good, lot lost step and weak no power.
I was planning my own CNC machine back in school. Back then we hadnt had such a broad software base to choose from as right now. Thats why I gave up because 14 y.o. me wasnt able to understand half of what the make shift software avaiable to makers requirred to know. Now I feel like the bug bit me again and maybe I will get out my old plans and revisit the idea...
Mister sorry for my langage but i'm french : You have my totally respect realy !!! Bravo Monsieur Your mind is very accuracy realy !!! thank for your ideas ... I'm very exiting about your chanel Long life for you . Eric Bergart Isigny sur Mer in France
I started with wood, and normal m8 threads and nema17 motors, but realized wood wouldn't be stable for long time. Just started a new project with only Steel and Aluminum nema23's T3x6 threads and 1.5kw spindel. Cant wait till finish
Damn, throwing shade us mechanical engineers at the beginning 😂, I'm learning electrical engineering as a hobby bro, recently got an alduino and planning linking the two fields together to make my own DIY projects. Can't we all just get along 😭 . Thanks for the tutorial btw keep it up
AWESOME, I kinda did the same thing, except for the X,Y,Z I used 8mm rods with linear bearings and epoxy'd them to the mounts with J-B Weld. I enjoyed your video and Makers Make the world!
Have you considered making a video where you test the multiple extremely cheap linear rails available online? I ordered some from ali and while i don't really know how good or bad they are they seem to work well enough for 3d printing and i'm wondering how they compare to quality rails.
Awesome, thanks for sharing!
woow nice project
why is it no one has ever as far as I know tapped the end of a shaft coupler so you can screw in the leadscrews then use the grub screw to tighten. This would eliminated grinding the leadscrew. I think your machine is a 10/10 for KISS design and will help beginers understand the machine better than just paying for one.
I know a commercial sign maker in the Los Angeles area that has router tables built on the same principle as this machine shown here in the video. Just because this is a very small machine, it does not take too much to use larger motors and larger stepper drives to make something that is even 8ft by 12ft or more in size. The most difficult thing with any machine is keeping the waste out of the electronics and making good use of the software, as some software programs are even too much of a headache to use if they are free.
One good start is using Mach3 or other similar software, as interface boards are for the most part quite affordable. I have designed and built many machines and have upgraded and repaired many more, but I'm a much better consultant at this point in my life due to spinal problems and other medical problems that limit my ability to do physical work. If anyone near the Southern California area wants help with some ideas, perhaps you could contact me. I am glad for Stefan and others as they show things from a hobbyist side that I have never really given much thought to. As I would not consider building a machine out of WOOD, but others have and they have earned many thousands off of their work.
The key thing with any design is not that you are interested in a machine, but what is the primary thing that you will use the machine for. If you are welding or using lasers, wood and many plastics are out of question, but if using it as a router for plastic anything even particle board is good for the body of the machine. Also if someone wants to hold a sheet in place for machining, a vacuum cleaner can be used as a source of vacuum to hold it in place. Key thing is what are you cutting, how accurate, and speed of construction, ability to modify for other things, and so forth. Just because some company makes a machine for many millions, does not mean someone else can't do the same for a couple of thousand or less. Be creative, and if not sure ask others what they think. There is an old saying that no man is an island... This is for the most part true, as one person can't do everything, as the most basic things will keep you from being creative, but with others we can come up with and create things that few if any thought even possible.
I've been an engineer for a few decades, and sometimes it is quite profitable, but many times it is a struggle just to have money to put fuel in the vehicle, have food to eat and keep the lights on etc. Do things because you enjoy them, because if you do thing just to try to earn money you will be hurting. There are many things in business that take far less thinking and have much better rewards than being creative in this world.
Really good to see this and how it works etc..thanks...Laurie
Good video and Excellent Verbal Walk Through - Thank You for making and posting
Great video. Perhaps I will build a cnc in the future as well. Your project showed a good starting point and gave good advices how it can be done in a cheap and easy way. Keep going on. 👍
wow, interesting that you get by without thrust bearings on the lead screws and flexible alu couplings :O 608 bearings really are not made to take lateral force but seems to be sufficiently sturdy :)
Lots of great ideas sir. Thanks for the great video. Shows what one's mind can do if really applied. Thanks again.
Well son, you want to know what I think about your project so here goes; I think it's genius in the fact that you started out simple, the way every endeavor should. Everyone now days has become so price concise they have forgotten what it's like when your parents aren't supporting all your, what may seem like hair brained schemes. This is where new technology starts!!!
Nice one buddy I am learning to build my own cnc just collecting parts
Hey Stefan, super, dass du das Projekt so durchgezogen hast! :-) Ich hatte vor 10 Jahren (glaub 2008 war das?) auch schon die Idee, eine CNC-Fräse zu basteln, hatte sogar schon ein Design fertig und wollte auch Schubladenschienen verwenden, allerdings 2 Paar pro Achse, jeweils um 90° angewinkelt. Erzählt doch mal wie viel mm/min bei welcher Zustellung du in verschiedenen Materialien schaffst, so dass die Fräser heile bleiben und das Ergebnis noch genau wird. Da ich mein Projekt damals nie zuende geführt habe interessiert mich natürlich brennend, was da so gegangen wäre. Fräst du auch Aluminium damit?
Ich habe mir gerade aus China so eine 2418 CNC Fräse zum Platinenfräsen besorgt. Die ist komplett aus Aluminium mit Rundwellen als Linearführung. Die hat schon ganz schön zu kämpfen bei nur wenig Zustellung in Holz (0,5mm Zustellung, 100mm/min, 1.5mm Diamantverzahnter Fräser), bringt dafür aber auch ziemlich genauge Ergebnisse. Die Kräfte, die da auftreten, scheinen doch ziemlich immens zu sien.
