In industrial automation we allign rails with the finished platform and sliders on top. One Rail is fully fixed, then the slider is moved from end to end to automatically align the second one.
I started building cnc machines for a micro production shop that makes spinning tops that spin for 45+ minutes on a special base I haven't released yet. This was 7 years ago. My day job and life has my passion on hold. I hope I can some day get back to it.
When the video appeared on my list this morning, it already had the red line along the bottom, suggesting that I had already watched it, so I nearly dismissed it! Luckily I double-checked! 😊 Looking good, thanks Tom.
Next time you need to tap holes in aluminum get a Good quality spiral tap and a drill. You can plow right through in a single pass and tap each hole in about 20 seconds.
Other than friction and bendy bolts there doesn't seem to be anything to stop the Y-axis motor from partially rotating under it's own torque and causing a position error. Why didn't you just make another plate like the one holding the Y-axis bearing block?
You don't run water in a "water" cooling system. They always have some biocide and surfactant in there as a minimum. You can buy these as additives for PC water cooling, or just use car radiator coolant pre-mix. The high glycol content to prevent freezing might be useful in your garage, but does reduce performance a touch. Probably not enough to matter, just use a faster pump and bigger rads and fans.
I’ve been running 2 air cooled 4KW spindles for over 4 years now. I’ve run over 3000 jobs, many of which were 3-4 hours at a time. My garage has neither heating nor cooling, so here in New England the temps range from under 0 to over 100F. I can’t imagine what advantage water cooling has to offer. Maybe a little quieter?
It would be ridiculously slow as a 3D printer because of the screw drives. If you replaced the screw drive system with a faster method, the rigid frame would cause all sorts of print quality issues.
Or use automotive coolant if the parts involved can handle it. It'll last heaps longer than water alone and (assuming it's an antifreeze type) it will prevent any issues with frozen coolant bursting weaker parts of the cooling loop if it gets cold in winter.
0:49 - pro tip - machinist tap = you can mount it in a drill for extra Z axis stiffness add 2 pieces of aluminium flat bar opposite the spindle (as long as the axis- screwed to it ) so you create U shaped mount for bed u can do the same but under it in XY axis ,or maybe another project -- 2 pieces of aluminium (with dozen holes in it) and epoxy granite in between
Do not use the parallel port. There is a hundred dollar adapter that easily lets you use a USB port. I run Mach 3 and Windows 11 ( you can use any version of Windows)!! I just use a 200 dollar minimal laptop.

I think you can get off the shelf cast/machined motor brackets with mounting provision for ball screw support blocks. They have machined pocket that ensure your motor and ball screw have good concentricity.
We didn't mind waiting :) Think its just sad there aren't more companies that do semi pro (hobby) style CNC's , here in NZ we had a company who was going to do them but went out of business i guess due to lack of people buying larger machines and everyone knows shipping a big item from overseas these days will break anyone. Look forward to next video
I build a high speed cnc router to mill foam around 7 years ago, putting things together was easy, but caliberate the alignment for rails was so damn hard.
So something I learned when I made my cnc machine is that because steppers NEVER turn off they can get hot enough to melt the 3d printed part over a long operation. It shouldn't cause a major failure because it will just make the plastic soft and deform, but its still something to watch out for.
I hope he comes back and does this properly! Most people 'tram the spindle' without accounting for correct orientation of the axis relative to motion. Dial indicator to measure z axis relative to X and Y. A flat bed and decent 123 block will do it at a pinch.
Hi Tim I have worked on CNC Mills for over 13 years and what your doing is great. Just a thought maybe you could get a sheet of C250 Tool plate (30mm thickness recommend for a bed) as this makes good cheap Ish bed material. Any tool plate is good as it should come flat and parallel and stress relieved. If you phone up material suppliers they sometimes have a big off cut they will sell cheap. Try SMITHS, Optima metal services, aalco, mill stainless. If you ever need any CAD/CAM or support and I can help just give me a message. Cheers Luke
Do remember that the motors are not supposed to rest on the painted, non-machined surfaces, it may tilt them, and to be picky, it does not look very good that way. Exciting project!
Very interesting project. Looking forward to seeing it fully setup and milling stuff. I would like to build a smaller desktop size cnc and was curious to find out what type of extrusion profiles have you used for this build?
4:50 If you're looking to get better quality with that filament, you'll have to remove the mosture built up inside it. If you heat the spool in an oven or a drybox over time ( temp. depends on material, but theres a few recommended values and methods online it'll take the moisture out of the filament. You can also toss some dessicant packs in a box, and it should keep the spool dry for a while.
Freakin awesome man! I've been enjoying your videos the more into engineering and machining i'm getting into. Never really thought i'd be interested in that sort of a thing but well i definitely am, which is kind of funny. But yeah what i wanted to say is that with every kind of work, you always think your allllmost done like halfway through, so you know there's prooobably alot of work ahead i'd wager, but its super cool seeing this process, and thanks for sharing it!
I bought a windows 10 machine with a parallel port adaptor, but it didn't work. Apparently it requires windows 7 32-bit or older. However, I also tried a windows 7 32-bit machine and the mach3 driver blue screens the computer haha

Still not cheap, but clickmetal seems to have the cheapest aluminium tooling plate in the uk. Cheaper than aluminium warehouse's standard plate. About £150 for 520 x 520 x 16mm
Maybe I am dumb, but couldn't you use a frame out of cheap angle iron, which fixes a thick wooden spoil board, that you use the cnc mill to flatten peferctly parallel to your x and y axis? For many operations I would assume, that you would add a vice with some bolts on top and big sheets of iron etc could get screwed down with a bunch of wood screws: Drill a few holes in strategic points, fix with a woodscrew into the spoil board and remove everything once you are done.
The fan on the motor is fine. But the shroud sucks. 3d print a mount that allows you to attach a 32mm or so flexible hose and vent it away from the cutting. It allows for cool air and limits dust and chips and also, significantly cuts down the noise. As most of the noise is from the fan!
I totally get that you can afford to just buy a top end CNC machine, and I also get that this is about challenging yourself but what I am genuinely curious about is is this a cost saving device? Taking in account your skilled time, labour, knowledge and materials did you actually save any money? Not that it matters, I am just curious.
and can buy pci or pcie paraller port card, cost normal 20-30$ working well, i have my computer 2 pcs paraller port card and use my cnc lot input/output ports.
You might want you a fancy 4 spool printdry filament dryer. Combined with my AMSes it makes it much easier for me, a lazy person, to actually dry filament.
Please tell me some of the first parts you're going to machine with the new CNC are replacements for those long bolts with the aluminum sleeves that mount your z-axis. Those must easily be the weakest link in the design.
Do you know what kind of control you intend to use? A friend and I have developed a linuxcnc raspberry pi hat. It is currently in testing but we are trying to get them out there and being tested. In fact I am in the process of putting one on a very similar machine.
2:47 I thought you would put the bolt in the lathe and cut it. Well, that solution of just removing the washer was simple. (and that's why I never finish my projects)
it'll solve it in the short term, but in computer water cooling people add biocidal chemicals to the loop to prevent microbial growth and a similar solution would probably be useful here.
water cooling NOT used water, cooling used normal car cooling liguid and mix little to water, then not ewer have moldy problem, car not have moldy problem ewer.
I was looking to do something like this years ago... Bit atopped because of cost among other things. Will you do a overall cost at some point? Or you prefer not knowing? 😂
European mindset is very different from a Turkish mindset. He said, it is difficult to find a cutting bed with a reasonable price at that thickness. If I were him I would invest to best plate which fits my needs and try to compansate its cost in the future.
Why wouldn't you build the base from steel C channel so it's cheaper to make a much larger CNC? It's not like weight is a factor and it's just the same amount of work.
More difficult to work with unless you already have a lot of metal working tools and it's generally much less dimensionally accurate than extruded aluminium as delivered.
@@PiefacePete46 PrintNC isn't accurate without much work , its 100% as accurate as square tube used and 99% of people won't tell u that you should mill both sides of square tube for it to work properly or rail twist = damage.... plus it's really hard to mill it because square tube have stress in it from manufacturing = u mill one side , the other one bends so for everyone wondering why extruded aluminium ....its super accurate out of the box
@@ErtsenPlayGames : Absolutely! That is exactly the point I was trying to make. (Maybe I did not word it clearly enough.) I watched every video on Bryan Howard's channel about the making and refining of his PrintNC. The end result is a very useful machine, but it took a HUGE amount of time and effort it took to make it as accurate as possible. The first part of my comment was that C section is a worse idea than square steel tube. I wasn't suggesting that steel tube is a better alternative than aluminium profile, even if it is heavier and stronger. I completely fell in love with Piotr Wysocki's granite gantry mill though, and the amount of time he spent chasing microns was amazing!
@@PiefacePete46 Granite machines are incredible, I've wanted to try my hand at the more accessible option of epoxy granite for a ages but it still requires an abundance of surface plates or a surface grinder the size of a small house to take proper advantage of.
Do you already know what elctronics you want to run? I am using duet3d boards but i find it a little awfull that it doesnt use screw terminals only pins
@@TimStation these are great i am using the 6xd board. With external stepper drivers. When im remembering corectly there should be a 3d model on the website. I would recomend making a a custom pcb with screw terminals. Something like the boards for arduinos. I am using a pc the web interface is great. On the duet website there is an explanation how to connect it to the pc. I cant recomend that way. The Board has a sd card put them in the pc and change the ip adresse there way less work. For the vfd you also need an 0-5vpwm to 10v analog converter the duet board doesnt support 0-10v output. Or getting a fvd for pwm signal but these are not very common. The website has all documented that stuff but for a new one like me these where the Problems i had

Hi, Tom I built one of your air engines and it is mysteriously only running backwards do you have any idea why this is?
Why wouldn't you build the base from steel C channel so it's cheaper to make a much larger CNC? It's not like weight is a factor and it's just the same amount of work.
More difficult to work with unless you already have a lot of metal working tools and it's generally much less dimensionally accurate than extruded aluminium as delivered.
Square steel tube, rather than C section. But there is no way it is "the same amount of work"!
You are pretty much describing a "PrintNC" machine.
@@PiefacePete46 PrintNC isn't accurate without much work , its 100% as accurate as square tube used and 99% of people won't tell u that you should mill both sides of square tube for it to work properly or rail twist = damage.... plus it's really hard to mill it because square tube have stress in it from manufacturing = u mill one side , the other one bends
so for everyone wondering why extruded aluminium ....its super accurate out of the box
@@ErtsenPlayGames : Absolutely! That is exactly the point I was trying to make. (Maybe I did not word it clearly enough.)
I watched every video on Bryan Howard's channel about the making and refining of his PrintNC. The end result is a very useful machine, but it took a HUGE amount of time and effort it took to make it as accurate as possible.
The first part of my comment was that C section is a worse idea than square steel tube. I wasn't suggesting that steel tube is a better alternative than aluminium profile, even if it is heavier and stronger.
I completely fell in love with Piotr Wysocki's granite gantry mill though, and the amount of time he spent chasing microns was amazing!
@@PiefacePete46 Granite machines are incredible, I've wanted to try my hand at the more accessible option of epoxy granite for a ages but it still requires an abundance of surface plates or a surface grinder the size of a small house to take proper advantage of.
520x520 30mm machined cast aluminium 7021 tooling plate costs about 300 euro
Me who forget and see the notification: A surprise to be sure, but a welcome one.
I love this video 🌈
Looks good.
Do you already know what elctronics you want to run? I am using duet3d boards but i find it a little awfull that it doesnt use screw terminals only pins
I'm actually planning on using a duet3d board. Is it a good choice? (Other than the pins)
@@TimStation these are great i am using the 6xd board. With external stepper drivers. When im remembering corectly there should be a 3d model on the website. I would recomend making a a custom pcb with screw terminals. Something like the boards for arduinos. I am using a pc the web interface is great. On the duet website there is an explanation how to connect it to the pc. I cant recomend that way. The Board has a sd card put them in the pc and change the ip adresse there way less work.
For the vfd you also need an 0-5vpwm to 10v analog converter the duet board doesnt support 0-10v output. Or getting a fvd for pwm signal but these are not very common.
The website has all documented that stuff but for a new one like me these where the Problems i had
love it!
Tip for threads: even a router is able to mill threads, and chinese threadmills are more than good enough 😅
those ballscrew and linear rail sizes are weird.. the only combination that works without millijng or spacers is SFU1204 with HGR20 both are 30mm in height.
