It has taken forever for me to get this footage edited, but it is finally here.
Please leave comments on areas you would like me to explore further...and faster. I need to learn to make shorter videos.
Sketchup drawing of the major components: Here is a link to the plans. It is a Sketchup file with different view tabs and all the main dimensions.

Thanks so much for documenting all of this for the rest of us!
great job! They run the coolest lines through the cable tracks with the wiring.
Exactly what I have always dreamed off. Have started building an exact replica. Thank you for sharing experience and plans and comments. You are a very generous person.
Impressive design and fab. I’m building a single axis stepper driven plasma cutter. This video and the one on servomotor sizing was very helpful. Thank you for posting.
Well done, sir! Digging info on building my own and you have presented the key aspects in a very informative manner. Looks very solid and easy to understand the structural components. Thank you!
This was very nicely done. I like the fact that you mounted the bearings facing up. Many DIY'ers side mount these which significantly reduces the lad bearing capacity of the assemblies.
Thank you for showing us your work. You are very gifted. I enjoyed learning something
You're one of the cooler boomers i've come across on youtube. seizing the means of production, looking forward, and doing cool stuff.
Nice, organized setup. Well done.
I appreciate your build and video- I am just starting my journey to build a CNC 3 axis router similar to yours.
I look forward to the plasma build.

Nice Job! I'm just embarking on a build myself. Thanks for sharing your ideas and experience.
Thanks for your time going over this. I am interested in CNC and possibly building my own. Your input/advise has been very helpful.
Thanks and good luck. The whole home CNC thing is really growing. I think the trend is being over shadowed by the excitement of 3D printing. P.
Nice video tour of your CNC. I in the design/build phase of my own and love to see others ideas and designs. Subscribed and looking forward to more videos!
Very well built machine. Thank you for sharing.
very nice table, I like the clear design. It Looks stable.
Looks like a really nice build. I am looking at doing the same thing. Thanks for the video on it!
Who but a woodworker would build a machine with WOOD parts! I had not seen your design (this video) before I started my designs fo a machine, and it is amazing how I came up with very similar designs; except for the horizontally mounted X axis; have not started the build and this video is making me re-think my deigns. Thank you for posting it!
Wow, thank you for sharing this with us and especially giving back and making your Sketchup file available for us. That file makes such a difference for replication. I will try to make something using yours as a base for creating mine.
Good luck on your build. Send me some pictures. There is one up and running 'down under' already.
Awesome project. Looks fantastic.
Well thought out setup. If anything can be taken away frm this, wld be the reminder that you can mock up on wood etc before hand as you did w your plate. AND mocking up even the electrical boxes will save time and space. Anyone cld look at your setup and know what was what AND how much thought went into each part of the sum.
Great video. You put out some very usefull info on building a nice looking CNC. Thanks.
Very nicely done. Congrats!
Wonderful, thanks for sharing, still dreaming of the day...
Beautiful machine you built. Well done.
Thanks. I appreciate it.
Greta video, thanks for a really good overview of your machine. really nice work you have done.
I am very slowly putting together a CNC of my own and given me some nice ideas.
Great choice of the Z axis having stationary blocks and moving rails. The rails tend to stiffen the plate and allow for greater Z clearance. Also placing the Y axis rails near the height of the X axis makes for better rigidity and less issue with debris on the rails. Excellent work!!
You don't know how many times I have questioned the placement of rails vs bearings on the Z. Nice to have someone say I did it right. ;) P
Great stuff,..Your'e absolutely right about grounding everything Preston. You can tell how over the years grounding has become more and more important and since the advent of smaller and smaller voltages I/E computers they've gone and increased the size of the common or neutral......I wont start in on clean power....lol
Even though this video is 5 years old, it's still full of good material. Thanks. And thanks for including the sketch-up file (I'm doing my design work in Solidworks, but that's not a problem).
It is still relevant. The machine is still working great. I only have made a couple upgrades, primarily to the rails. ~P
looks solid - great job
Just found your channel, beautiful job on the CNC machine. I am subscribed!
Interesting and helpful. You're a good teacher. Thank you.
Great build there. I also use Mach 3 on my scratch built CNC
I really like your design. I think i will do something similar for my next machine. I like that you can feed and index a 4x8 sheet.
Very well done, considering that you've literally custom bult it according to your criteria. Look forward to seeing more soon. Kind regards.
well done all the best from John in Texas
Looks great, awesome job and thanks for the video.
Great build and really nice vid. I appreciate this has all good info for my build. I’m going with all rack/pinion and v-quad Linear rail sutethe x/y
Nice work! Love the controller podium idea. I hope you post a schematic for your control cabinet.
Looks like a lot of thought and effort went into this machine! I'm building one from scratch now and can assure you it isn't that professional looking... Cheers,
Nice build and good narration and thank goodness no inane music. Enjoy your machine , I have just about finished putting my 1075 openbuilds machine together and have done something very similar with the electrics, , nothing on the machine and all in a ventilated metal box and a big paddle on off switch on it. I'm just using the black box grbl controller and dont need separate driver modules so its a little bit smaller but just as enjoyable. I do not understand why so many people don't do the electrics in this way.
It is the best and safest option IMHO and keeps all the crap out of the main system brain. I live in 240 volt land so I will also be using a VFD spindle and hope to also build a fully insulated enclosure over the whole machine but allow for tiling , I too have tried a router and the noise difference is huge, with an enclosure as well even more I am hoping as that will have soundproofing but its going to cost half as much as the main machine so its another year for that bit.....Cant wait for the spindle to arrive now.....Many thanks for sharing.
Hell of a machine. Fantastic work!
Thanks ~P
Incredibly inspiring build summary! One of these days I'm going to pull the trigger and make something like this happen. I still feel I have so much to learn. May I ask what your background is? Just subscribed and I'm looking forward to seeing more of your videos. Thanks for taking the time to record, edit and share. I, like many, really appreciate it. Joel
Great video man, really appreciate you sharing it!!!
you know what might be a sweet project to do in aluminum, some end caps for that square tubing. I think that thing is sweet though, good job for sure.
awesome. I envy your shop and knowledge.
Awesome build!!!
good job I'm a tool and die maker and I'm impressed. once you get you speeds and feeds down that things gonna be unstoppable
Thank you. That is high praise to me coming from someone with tool and die making skills. ~P.
Thank you give me some great info and ideas for my first project
Looks real good and good work
I could NOT do it, you did fantastic, keep it up...
I am impressed with your build and the first run of end results. Thanks for sharing. I too am thinking of one day constructing my own CNC table and given I have a MIG machine, steel and can produce nice welds (as opposed to yours - tongue in cheek!), will go on the fundamental design of welded cut steel. I can also MIG weld aluminium > 3mm thick and may decide to construct the framework out of aluminium extrusions, but not the fancy T-track ones you see most CNC machines made from but solid chunky bits of framing into which I can drill hundreds of holes & taps. That way, if heaven forbid I needed to move it, I could actually lift it with a couple of guys.
One snag is the box for the controller gear - out of my league but hopefully I can find someone who will help me out there.
Whilst you have over-engineered it to billy-oh, it will work true for decades and as long as the motors don't burn out, you could run this machine as hard as you want and it won't miss a beat.
One thing does concern me however: the round bar / linear bearings and the ballscrew / bearings are open to the air and dust and chips will settle on them. I presume you will add a vacuum cleaner head to trap 90% of the flying debris but do you think constructing covers for your railing would become necessary - or would a good old fashioned broom and dust cloth do the job?
Overall a very impressive example of home-made ingenuity.
Very smart design of X-axis. Less height=extra rigidity!
Yes, I noticed that aswell - going to build the same type.. Wonder why so little people build it this way?
@@tadasrudnickas3132 because the rigidity there does nothing.
Bravo........heads up note.......two things........magnetic shield on cables motors and cross cables at 90 degress.....cheers
nice explanation, nice machine, congrats my friend.
Great vid man, thanks for sharing!
Very nice work !!!
Just subscribed. A lot of good information in your videos. I look forward to viewing future videos.
roireb1 thanks for subscribing.
Very nice ...Thanks for sharing.
Very nice job and nice improvements on the machine. Would you have a parts list for the control panel box and wiring diagram for it?
I had a similar issue with building too heavy of a frame to move easily in the workshop. Might try setting up the bottom side to accept a pallet jack to aid in the moving process.
Great looking machine !
Great build!
I have a 4'x4' router I built from a FineLine Automation kit for the mechanicals. Right now it has the original rack and pinion drive and bearing blocks with 6 roller-bearings each, riding on 1/4"x4" x6" steel rails for the X and Y and a ball screw and linear rails for the Z. Dual Y drive and all NEMA 23 steppers. Trying to keep the bearing blocks adjusted for the 2 ends of the gantry are a nightmare. I had paying jobs lined up but had to cancel them because I could not hold the accuracy on the Y.
I would calibrate and be cutting perfect circles, all backlash compensated by Mach 3. Then 1/2 way through a job, I would be cutting ovals. X and Z are fine. I can hear the gantry binding and releasing as I traverse it back and forth on the Y with no load. I scrapped the steel rails to 12" flatness (longer than the bearing blocks) but no improvement.
I have purchased 2-15mm ballscrews with nuts and bearings from china and they are very clean and precise with no discernible (by hand) play. I also bought 2 Japanese linear rails removed from machinery in Korea ( the profile kind with 2 bearing blocks each with recirculating bearings.). I cannot tell they have ever been used and are smooth and tight. All these are 6 feet long. I have 2-960oz NEMA 34 motors to drive them, one on each side of the Y. Getting rid of the rack and pinion and the finicky original bearing blocks.
I assume this is overkill grunt for my gantry. All of my framing is 3x3" alum. extrusions and spindle mounting plates 1/2" alum. Even with a 6' steel rail, I can lift the gantry by myself. I didn't think to weigh it before assembly but I would guess less than 200 pounds.
My question: Would it be better to keep the dual Y drive with the ball screws and 2 NEMA 34s OR redesign the gantry to be driven from 1 motor and ballscrew under the center of the table and save one of the motors and ballscrews to convert the X axis?
Is that enough info. The reason I would want to is I would only have to buy 2 rails to complete an X upgrade. Perhaps even round like yours.
Sorry. My bad. I just mic-ed my balls screws and they are 2005s 20mm x 5 pitch.
I thought they looked better with those massive 34s. Esthetics is everything. :-)
Awesome work! I'd love to recreate this same build for a plasma table... Currently fabricating a small turn table for welding with a NEMA 23 Stepper motor. Those motors are awesome!
I can't guarantee timely, but I am working on a plasma table next. I have a rough design in my head and have started collecting parts. I hope to start over the holidays.
Awesome job Preston! From the square steel legs to the best x axis I've seen on TH-cam this is a great build!
Just a thought, but if you continue with your plan to leave the steel uncolored, you might want to give it a light coat of clear poly to keep rust down some. I'm a fan of the bare steel look too, but in a couple years you'll get less happy about rust stains on your pants, hands and all your projects.
Thanks for the compliments. As for the bare steel your point is well taken. It is coated right now but not with poly. A little secret I learned from an old timer that used to do some auto restorations. Go to the auto parts store and pick up a can or two of 'battery and ignition sealer'. Spray can of this clear stuff that goes on very thin and lasts for ages. It can be removed with solvent if you want to paint later, or I have painted right over it. It dries super fast and leaves no glass. It does however have a nasty off gas smell. I will only use it outside. Makes lacquer smell good.
very nice build..
Excellent! Thank you.
Good job thanks for going to the trouble of showing us your project very nice :)
pretty interesting cnc design, especially Y axis. subbed ))
Very nice build. Do you have any cad files for the control podium?
Thank you for share it, and for give us your time on making the video. Great.!!
Your welcome.
@Simon Messer Kit for what part of this build?
¡¡ I loved the bucket !!
Thanks for sharing , I like your engineering . I was debating to build one myself with square block hiwin linear bearings . Wish I had enough confidence to weld the base and get it acceptably accurate. I was going to use t slot extruded aluminum, but your idea using steel is much better imo . Just a little harder for me to implement , so I'm sticking with the aluminum
A lot of the design features I built into the framework came directly from my consideration of not being able to fabricate a perfect frame. Once I had those adjustments baked in, it took all the pressure off of trying to make a perfect welded frame. Good luck in whatever you do.
+sbirdranch
Yes I realize that . You have some good ideas for levelling and squaring the gantry , and that should come in handy for tramming the spindle /router .
All good. I don't think you are missing out much (apart from some possible job screw ups) by skipping the centronics port and going to an ethernet smoothstepper. All of my glitches were eliminated by spending the extra $ for the smoothstepper. My machine even sounds better when it is running! All the best with this beast.
nice machine! I am using those spiral cut aluminium motor/shaft couplers too. but they are springy on the axis that moves the gantry and router. how is it that yours aren't springy?!
I had to cut up a credit card and shove the pieces between the spirals to reduce the spring. but the gantry still bounces a little.
thank you for this information. brilliant
Thanks from Bangladesh .
I seen you video on your CNC, like it. It's the TOP
I wish I know what the total cost was, I would to build one myself.
Great Job! Thanks!
Awesome build guy
Joe Eichholz he's not your guy, buddy
Great Job!
What stepper and controller system did you use. Also motor torque. Nice job.
you made no mistake. no matter the windows environment, a dedicated pulse train generator is a GOOD thing to have. Be it ESS Smooth Stepper, UC100/300, centroid acorn etc etc etc. you made the right choice.
Great Video nice machine! still building my system although not as intricate or massive as yours but fun none the less. Great job
As long as you are enjoying the build, it doesn't matter. Best of luck. I have continued to add to mine with air and vacume and such. It I even call it done someone will expect me to put it to use. :) ~P
AUDIO QUALITY!AUDIO QUALITY!AUDIO QUALITY!AUDIO QUALITY!
The quality improved when you wear the microphone or have it very close to your head.
wow man great work . I'm armrest . thanks for sharing
Excellent video!
Subbed
Very Cool, Thank You.
Great video
Great build and video. I look forward to seeing your plasma cutter. What is your maintenance plan for the ball screws and slides? Do you feel the need to shield these from dust and in the future sparks from the plasma cutter?
The bearings have wipers on them, but I still try and keep them from getting too dirty. With my change in plans, I won't use ball screws and linear rails like these for the plasma version. It is way more precision then I think a plasma table needs. That said, it was the concern for sparks and grit in my original plan that had me put the rails above the work surface.
Thank you for the video, I love your design. Sorry if I missed it but what size motor are you using on the Z axis? I'm designing a machine that is very similar to yours where the ball screws will be exposed. Have you had any issues with loose clothing or anything getting caught in them? I'm thinking I might make a cover.
nice!! stable!! confident apparati!!
What an amazing machine and shop! I'm not sure if any of the other comments made it clear, but the 64-bit CPU in the computer can also run 32-bit operating systems and 32-bit software. CPUs like this are backwards compatible.
You are the second person to make the 32 / 64 bit observation. And as a software engineer I get it. For one of the few times in my life I followed the directions and might not have needed to....but.....my original intent was to use the built in serial port, and that requires using the Mach 3 serial driver. I did some reading/researching on how that driver works and it is so close to the 'metal' that I don't believe it would work on a 64 bit architecture. That driver actually hi-jacks the system clock in order to send out the pulses. This is a very surgical maneuver and is why having the system taxed with any other processes becomes so problematic. In the end I went with the smooth stepper to avoid what the documentation said would be an issue. The up side is I have never had any of the problems with stepping getting wacked. I can surf the web during a job, and not worry about anything. In the end I think it was I nice mistake.
So all of that said...if anyone has tried it, I'd be interested to know how it went. Thanks for commenting ~P.
Ah, I didn't realise you have a background in software. You're right, if the driver is supplied as a 64-bit binary then you must use a 64-bit OS. You cannot use a 32-bit driver on a 64-bit OS or vice versa because the ABI (register names/widths/purposes, argument passing on stack or registers, etc) is different. What you describe sounds like the Mach 3 is doing the job that a microcontroller would usually do. A modern pre-emptive OS (Windows/Mac/Linux) usually isn't good for this as any userspace task can be interrupted or rescheduled by the kernel. I guess there's enough leeway in your purpose that small task-switching breaks don't affect it enough to matter. As you've observed, when you max out the CPU then the userspace task has larger gaps between being scheduled on the CPU and the result suffers. There are several "real time" operating systems which partially mitigate this problem by disabling some pre-emptiveness so tasks get interrupted less and get more predictable latencies. A microcontroller doesn't have this problem as it has no pre-emptiveness to service, the CPU is dedicated to running one task and only one task.
Love your CNC, will be watching your next build on changes, I've been wanting to build one for sometime but never had the room before, now new house with huge workshop so it's back on my wish list, I was kinda wanting something similar to your idea as wood router / plasma and maybe laser all in one, but maybe for now just wood sounds like it's not going to be to simple, at least something to fit 4x8 sheet of ply if need too.
On the Z axis how long are the linear rails?, are you still happy with them?
They are about 12 inches long. They have been fine when considering length, but to be honest, I am about to replace them with the square type rails. When I try and do any drilling or spot drilling, the Z pushes out of alignment. I am hoping to reduce this with the new rails. ~P
Wow, super job :)
Wished I saw your video before building mine. If I build another, going to incorporate lot of your ideas. Great job, both with the machine and your video.
Mike
Thanks Mike.
Excellent job!! I am planning on designing and building my own CNC Router setup and was also thinking of using steel square tube for the gantry and frame. Other than being able to get everything true and parallel and needing to have adjustments to compensate do you think there was any other draw backs to using steel versus aluminum? Also I was wondering if you could give me am idea of what your whole setup cost? Thanks in advance and again great work!
I don't think there were any draw backs. None in hind sight. All positive things like ... - Material was readily available - Material cost - and probably most important, I could weld it. I can't tig aluminum yet.
If I had to do it again, I'd plan on $2kUS.
Thanks for sharing
Love it.
Important piece for strength. Anything but wood.
Awesome I am thinking about building one working on learning the drawing part first.
That is the key. It is also the part people overlook when they run out and buy one of them cool new 3D printers.
You can make some fun stuff and get your machine running quickly just by using Easel from Inventables. Good Luck. ~P
