excellent job !, you brought hope again to me because ball screws are expensive (about 200$+shipping!), I was afraid of using belts instead but you prove that wrong .many thanks!
SIR YOU ARE FUCKING BRILLIANT. i am making one using linear rails and ball screws with garage tools. Id have made it this way if i ran into this video earlier, for lining two pulley holes i believe is ALOT easier than what im trying to do right now or so i think
Thanks for the reply my cnc has threaded rod 1/2 20 on the x and 1/4 20 on the z and y It is spot on most of the time but i have lost a few steps along the way i have it set to 4000 /30/4 seems ok its a tiny bit less on the x axis after calibration x is my long axis cant wait to see your next video very well done vid btw I hope to post a few cnc vids my self soon Jerry
Thanks again, belts are ok, but I would go for ballscrews if I should build another one, but depends what you use it for. I will do another video soon, and will try to show the settings there. It can go alot faster but this is ok, the importing thing is the acceleration, so you can keep your feedrate when changing directions, there are alot videos here on youtube where the machines can go very fast, but the acceleration takes allmost the working lenght of the table to get there, thats no good.
Hi Morten, thanks for sharing. Many smart details show its ingenious ! It proofs your innovative approach can work, truly unique. I wonder you say you would go for ballscrews next time. Can you please explain why ?
@antennasbc, If you would just put the 18tooth directly on the stepper motor you would have no torque in the machine, then the motors would stall easy - so it's important to have this.
@alswift1 ,Thanks, on all axis between the stepmotor and output axle I use belt type M5-9, from the output axle I use M5-15 but on the X axis I have 2 belts - one on each side. I have access to a lot of different materials, belts pulleys... but no ball screws, I figured it would be good enough with belts so I went that way. This is my first build, but if I should build a secound one I would go for profile rails instead of round rails, and ball screws instead of belts. Regards Morten
Hello again i have a cnc with similar steppers i drive threaded rod directly mine is insufferably slow i think im going to go with a belt drive system like yours whats the cost per axis for the needed pulleys & belts Fantastic job by the way Maybe show a screen grab of your settings and the ports and pin setup from mach 3
@alswift1 Not that important you will just have another ratio between motor rpm / axis movement. I have 16t on the motors going to a 72t and outputs to 18t on all axis, with a full step that gives in teory 0,1mm ( but in practice it's a little more because you stretch the belt to the axis). My motors have full torque up to 500rpm, so I am able to go about 10000mm/min at 500rpm, and I was lucky it worked wery well. I think it's important that the x & y axis have the same reduction.
@evaj0933 Hi, the stepmotors have long holes so I can tighten them by pulling them away from the reduction axle, the belts for the axis I can tighten the freepulleys, they need to be rather tight to eliminate backlash. I will try to do another video to show more details.
excellent project, congrats. How did you fine-tune the parallelism of the holding rods of the X and Y axes? I am building a MDF CNC and that became a big big issue here...
Hi I am planning to build a 6' X 6' cnc router similar to yours. However I would like to use fast travel ACME lead-screws with anti backlash nuts. Do you think they would work better than belt? I would use the router for wood and if I have to for aluminum.
@banananarchy, hej, det er faktisk ret nemt, du skal bare disable ACPI, og kører den som standard PC, Google "mach3 acpi" så finder du helt sikker en guide, ellers vend tilbage. Der kan dog være noget med spændingen på din parallel port som kan være for lille til din styring...
Congratulations you machine cnc excellent. what¨s step belt? I have straps silimilares 60S5m with them fodder them place like trinsmision of my machine cnc that nowadays this one with screws. Say to me your experiences with straps? Thank you for Regards reading myself from Venezuela.
hi this's a really good job! just one question: are these all 23 nema stepper motors and can i use only nema 23 for that size of cnc? or is it too much ? am new to this and am drawing a rough sketch to build a cnc so any tip will be appreciated
Hey Morten, I'm looking at buikd8ng my own CNC at the moment, do you still have the design in inventor you'd be willing to share?? I'm drawing one up right now!!
Super flot bygget! Hvad er xyz mål? hvilken dimension bruger du på føringerne? Jeg er gået i gang med lignende konstruktion, plade, men er noget i tvivl med dimensioner på føringer. Det bliver bælte på X og Y, og ball screw på Z.
Takker:-) 970x640mm er mit plan, vandring hvis jeg husker rigtigt 790x 575y 170z i mm. mine føringer er 20mm på y og z, og 30mm på x, alle sammen hærdede overflade slebne h6 aksler.
Morten Lundt Tak for svaret :-) Hvordan er stivheden i "gantry" sidevers ? Og er der ellers noget du har erfaret med plade konstruktionen jeg bør være opmærksom på ? igen, super flot maskine :-)
Bjørn Christoffersen Jeg syntes stivheden er ok til træ og plast materialer, og ellers må man jo sætte spåndybde og tilspænding efter hvad den kan klare:-) Angående plade konstruktion... min er 3mm alu med buk for at gøre den stabil, jeg ville lave den i tykkere plade med større buk hvis jeg skulle lave den samme igen, jeg har næsten en ny cnc til metal klar, den er med 25mm kuglespindler, nema 34 motore og lineære lejer, samt servo motor til spindlen. Hvis du allerede har ballscrew til Z så kør med det, men ellers syntes jeg faktisk på de 3 akser at Z er den mindst nødvendige da remmen typisk er så kort at den ikke rigtig kan give sig imod sætning til X Y som tit er lange. Mvh
Morten Lundt Tak for det, det lyder godt.Hvad er ombukket på pladerne? Jeg har tænkt mig at bruge 20-25mm ombuk, og evt. lave afstivningen indvendigt. Jeg har adgang til noget 2,5mm High strengt steel, en cnc stanser og cnc kantpresse (og pulver lakering :-) ) så det har jeg tænkt mig at bruge, og så bolte det hele sammen. Jeg har ikke købt ballscrew, endnu, så det kan nå at ændre sig, men det kunne være meget sjovt at prøve begge dele(og så dyre er de heller ikke fra kina). Jeg har kun lagt mig fast på SBR rails, 2,5mm plade, og 4 steppere(2 til x), resten er stadig i design fasen, men jeg er ret sat på rem træk. Cool, en mere, er det til dig selv? det lyder til at blive en kraftig sag :-) lægger du en video op af den også? man kan aldrig få for meget inspiration :-)
Bjørn Christoffersen Jeg har 25mm ombuk på siderne. Lyder spændende håber du smider lidt video op når du kommer så langt:-) Husk remme til at drive akserne med stålwire i og ikke glasfibre, glasfibre er ok til udvekslingen. Jo der skal nok komme lidt video af den nye, og ja den til mig selv...
I bought Nema23 270oz.in kit , I have a usual thread ( 1.25mm pitch ) .The problem is when I try to go fast with the axis I increase the motor velocity from mach's config but the motor hang and stop moving and making strange sounds . I don't have a larger pitch thread to increase velocity instead of increasing the pulsing rate . is there a limitations for pulsing rate in mach 3 ? ( i use 35kHz kernel 500mm/min velo. ) sorry for my large comment :)
Morten, hello! Really loved your design, it's simple, but full of details. I'm still building my own after several tries and a lot more failures than success, but just keep walking. I'd like to ask you about pulleys: First, are they standard or you had them custom made? or do you have a list of materials that would be best How did you hold the second and third gears, i mean, the one from the motor i get it, but can't see how did you fix the others and manage to adjust it tight. Please i'd love to get this answers as soon as you can!!!. Best regards Mariano info@modulart.com.ar
Hi, thanks. All the pulleys are standard, they are cheap so I did not want to use time making them. If you look at my other video "DIY CNC slideshow!" you can see at 0;46 that I use flange bearings to hold the "gear" axle, I used one in each. The motor have slots (0;46) so I can adjust the tension of the short belt on the motor, the belt that are connected to the axis have slots in the free pulley to adjust the tension of the belt. Hope this helps, regards Morten.
Really nice design. It looks very proffessional!!
Your machine started it all for me love the belt drive mine has gotten a bit bigger now
Can you share more info on the belt, pulleys and gear sizes? I'm doing my research to build my first CNC Router.
excellent job !, you brought hope again to me because ball screws are expensive (about 200$+shipping!), I was afraid of using belts instead but you prove that wrong .many thanks!
very well made - nice design and fast running
Hey Dude. Well done! It's a neat machine. I am building one as well and the design is very tricky. I have appreciation for what you did.
Nice machine dude
Hi Morten
That is a very nice machine you built!
Thank you very much.
SIR YOU ARE FUCKING BRILLIANT. i am making one using linear rails and ball screws with garage tools. Id have made it this way if i ran into this video earlier, for lining two pulley holes i believe is ALOT easier than what im trying to do right now or so i think
VERY nice build!! Makes my MDF creation look slow and amateur :-) Well Done!
Very well done you should be proud
@TrudgeRC, Thank you, but there are many fine mdf machines, many of those gave me the interest to make mine.
well designed and built!
Very nice work!
@João Leite, It was in fact very easy, everything is machined - lasercut sheetmetal and cnc bended, machined parts, so it was quite easy.
Thanks for the reply my cnc has threaded rod 1/2 20 on the x and 1/4 20 on the z and y
It is spot on most of the time but i have lost a few steps along the way i have it set to 4000 /30/4 seems ok its a tiny bit less on the x axis after calibration x is my long axis cant wait to see your next video very well done vid btw
I hope to post a few cnc vids my self soon

What can I use for nema 23 motor with nema 1.8 degree step? Is there any advice?
@Rogerquin, I had all the sheet metal parts laser cut in 3mm alu, then bended, and only a few parts welded, almost everything is bolted together.
@Aulio Diaz, It depends... you will get more stability in the machine with acme screws, but belts also have good points....
Very very speedy
surprisingly it is verry fast
at what speed do steppers turn please ?
@Udaya Varman, You have almost zero backlash when using belts (depends on the belts) but on my machine I can meassure backlash to 0.02mm
Thanks, the pulleys and belts are from optibelt.com, but look on ebay there are many cheap pulleys and belts there instead.

Great build. Where did you get your components i.e. belts, timing belt wheels, linear bearings, rails, etc.
Do you make the project available?

Great job! I wonder why not direct drive instead of 16 to 82 to 18? Is there an advantage to that? Thanks
nice machine. how much did it cost you? how was fabrication with al?
How are you avoiding back lash in Z-Axis.
OR the set up is dragging down due to gravity whet the set up in is top position.
Very nice where do you get the belts and pulleys ?

Amazing!!! I like so much your design of the CNC
i have a question... the stepper motor turns hot along the time work?
sorry for my bad english :(
would love to know what motors and gearing you are using?
hi this's a really good job!
just one question: are these all 23 nema stepper motors
and can i use only nema 23 for that size of cnc?
or is it too much ?
am new to this and am drawing a rough sketch to build a cnc so any tip will be appreciated
Hey Morten,
I'm looking at buikd8ng my own CNC at the moment, do you still have the design in inventor you'd be willing to share?? I'm drawing one up right now!!
where can i find the piece connected to the z axis that drives the x-axis?
What torque do your stepper motors provide?

hvordan har du været i stand til at køre mach3 igennem en bæbar?
To all, sorry for the late answers, merry Christmas to all...
What is the dimension?
I used 3mm alu sheetmetal for everything.
@Rogerquin, yes this is my first build:-)
I also used mach :)
@bmillmine Thanks.
