What I loved your part is, you can easily make those drills and cutting in CNC. But did it in handy. you give a hope to everyone who haven't accessable a CNC router. You made a confidence like you can do it.

i know right. thats how you do it

[@PiefacePete46]

Thanks Dejan, that one is a "keeper". I already have everything except the rails, and it will be a perfect project to share with my grandson who is just starting to show an interest in these types of project. I think a pen plotter would be a good place to start.

[@HowToMechatronics]

Glad to hear it! Yep, pen plotter would fit more. Lasers are a bit messy and actually dangerous. Cheers!

[@adamderbent6986]

Izvrsno. Bravo majstore. Imam prijedlog, kako povećat preciznost. Kod kalkulacije step/mm, koristiti maksimalnu raspoloživu dužinu raila. Ako je raspoloživo 400 mm, mjeriti i kalkulitati na cijeloj dužini. Naime, ako je greška očitavanja 1%, na 10mm to je jako puno. Na 400 mm, greška je prihvatljiva.

[@MrExNavy]

Thanks for this. I have looked at many, many, many CNC machines and this is by far the easiest and least expensive to build. I'm not a fan of the slider blocks used here because they get dirty so easy but since this is a laser CNC and not cutting wood like other CNC's, I think they will work just fine. Great job!

[@bj0rn2re]

Just orderet from amazon link 👌 this was cool

[@whiskeysquiker]

good point. Thanks for mentioning this. Recalculating my design.

[@MegaTechno]

What else do you recommend instead of the slider block? Will linear rods be a better option?

[@MrExNavy]

@@MegaTechno I think what you have is fine and will work good. As I pointed out, it's for a laser cutter and not a router, it won't get dirty like a router would make it. For the money, what you have is great and I wouldn't change anything if doing that would increase the cost of building.

[@MegaTechno]

@@MrExNavy I didn't decide yet, it is cheaper (way cheaper) to get linear rods! So if that doesn't provide a disadvantage, it seems like a win!

[@IainHendry]

Nice build! Keep in mind you need to have your belts parallel to the axis. Yours are angled slightly which means the belt gets tighter/looser as it gets closer or further away from the end points.

[@HowToMechatronics]

Yeah, that's a good point, thanks for the input!

[@pir869]

This is a nice project to learn cnc control as this could be upgraded slightly to use a small engraver motor,however,the use of MDF,the dust from MDF contains FORMALDAHIDE which is very toxic,so dust mask and good extraction,ANY wood material will absorb moisture from the air ,so ,you could either use same thickness large plastic (nylon)chopping board which will not warp with heat or moisture or water down PVA white glue to make an emulsion to paint all surfaces of the MDF after cutting to size,this will make it waterproof,make all screw holes self tap or drill holes and add emulssion,removing excess with a cocktail stick from screw holes. Nylon chopping boards can be found quite cheap,and are very strong and stiff when used in the proper dimentional axis to force,it can bend but will not compress easy so proper use is a must,along with PVA emulssion treated MDF,a very strong stiff frame can be made,though this project is very nice and the use of good linear rails is very commendable.

[@whiskeysquiker]

Wow, thank you for this. I appreciate the frugal take on this. I'm in design and part purchase phase. But I also want to create a machine with upgrade ability if i want to eventually get a CO2 tube. So I am going with a fairly sizable extrusion frame. But I was debating on a tslot/vslot combo, a tslot/linear rail combo, or tslot/linear rail (x)/linear rod(y&z) combo. But the ingenuity of using wood has me reconsidering because I can get more laser for my buck if I cut costs and use what I have in lumber and just buy rails. I so appreciate you taking the time to do this.

[@KevOXO]

I like the way you show how to build this, no 'this is what I prepared earlier' or pretending every hole was precisely on target.

[@HowToMechatronics]

Thanks, glad to hear it! I always try to be as transparent as possible in the videos. Cheers!

[@NikonCrayzee]

A bit late to the party, but I've started researching on CNC laser engravers so that I can start building panels for my XPlane simulator. This video is sensational and I am so thankful that I came across it. I am planing on using your design to build one, the only change I might do is to use (as you already suggested) metal brackets. The other change I was thinking off is using HGR15 rail blocks for the main axis instead of MGN15 (HGR is stronger and supposedly built to tighter tolerances). For the axis that holds the laser, I would use MGN12, to try and reduce the bending moment that the laser axis applies on the primary/main axis. Perhaps I could use the two Nema17 motors to provide a bit of counter balance. Your design is really fantastic mate - congrats, well done.

[@HowToMechatronics]

Hey, I hope you will have fun building one. I would also consider what I mentioned in the video, add another rail on the other side. The point of this video was to make the machine with minimum parts possible, but for more stable work, you can add another rail. Cheers!

Don't forget focal point. Should be in the laser specs. As pointed out, the belt positioning is also important. Curious as to resolution with this setup? I see these steppers are 1.8 degrees. Without additional hw, I'm assuming no half or finer stepping.

[@Nasir.alDeen]

[@omsingharjit]

Hello sir, Why my stepper motor is not continuously and moving in perticular axis while pressing the arrow keys and even movement is not content sometime it moves to Relatively large distance some times very little, sometimes not at all no matter how long I press the moving command keys or at any Step Level and sometimes the software misbehave ( not only this but other cnc software giving same problem), 1st i thought its Smps causing the noise I changed I even rapped stepper wires around choking ferrite but same issue so far it moves somewhat constantly but very tiny amount why? I am using clone uno with ch3 type installed driver?

This is was the kind of tutorial I was looking for. I currently don't have a 3D printer and wanted to know how I could go about starting a prototype 'pen-plotter', with something like MDF board. I'm hoping to use aluminium profiles along with the MDF, but I'm just starting to design so I'll have to work out if that is even feasible. Anyway, I'm glad I found your video, hearing your throught process was helpful.

[@HowToMechatronics]

[@dgo42]

Thank you very nice tool! But I want to make small correction for steps per mm calculation. You can calculated exact steps per mm. You use well known timing belt. Usually it has exactly 2 or 2,5mm per tooth. (there is also other timing belts, but this two are normally used for 3D printers) The stepper motor pulley has usually 16 or 20 teeth, so one revolution is 2mm * 16 teeth = 32mm. We also know, that usual stepper motors has 1,8° rotation per step or 200 step for 360°. Then 200 steps / 32mm = 6,25 step/mm. But usual stepper motor driver used by 3D printers has microsteps, some of them up to 16 microsteps per full step and some up to 32 (there is also much expensive with 256 microsteps). So if you've configured 16 microsteps you've got 16 microsteps * 200 steps / 32mm = 100 microsteps/mm I think you've 32 microsteps driver, 2,5mm/tooth timing belt and 16 teeth timing pulley, so your exact configuration is 160 microsteps/mm. Using 161.29 - you makes your engraving ~0,8% smaller as drawn.

[@HowToMechatronics]

Thanks for the input! That's indeed a good way to do the math. After few some tests, I actually ended up using 160 steps/mm which is exactly the same with your suggested calculation. Cheers!

[@DeezVlogz]

Hey man. I have a question for you. I'm planning on building a 600x500 engraver using this method.. I've never programmed one before, how do I set to size the the software.. do I plug it everything in an the board automatically know the size??? Help needed.

[@jamesbrown99991]

That's very impressive, especially considering the materials used. I was surprised that the unsupported axis was so stable. Awesome design.

[@HowToMechatronics]

Thank you! I probably should have mentioned in the video but as I was saving on time I didn't do it. When the laser module was fully extended there was a leaning of about 1mm. Though, the play was not coming from the rail, but the MDF base, or because of the method I glued an screwed the pieces where the X-axis was mounted.

[@jamesbrown99991]

@@HowToMechatronics Presumably a bracket would fix that. 1mm doesn't sound like much; if it doesn't mess with the laser focus, then all's good.

[@MrJesus4194]

How about adding a roller blade wheel on the end of the y axis to support it kind of like what they do to a large gate so it doesn't sag?

[@engina1572]

[@HowToMechatronics]

[@puffinjuice]

Nice and simple! Do you have any problems with the arm that carries the laser head? I was thinking that it would be cool to extend the cross arm out the other side to counter balance the laser head. You could use the same belt to move a counter balance opposite to the laser head.

[@PiefacePete46]

yes pineapple pizza: That sounds like a good idea. It would probably pay to keep some weight on the laser side to preload the bearing. However... this works so well as it is that you might just be adding complication for no benefit?

[@HowToMechatronics]

Thanks! Well as I said in the video, the machine is not that rigid, but works quite well. I probably should have mentioned that in the video, when the laser head goes to end of the arm, it leans down about 1mm, but it don't make much difference for the laser engraving. Actually, I notice that the play was coming from the MDF construction itself, not the linear rail. I mentioned that in the video, that the way I glued and screwed the MDF pieces that hold the X-axis was not that good. A more stable way, for example a metal bracket, would make a difference for sure and it would reduce that play of the Y-axis.

[@almosh3271]

From what I've watched on you tube if you don't have a stepper motor to the driver, the shield will fry and become useless. There are four slots on the shield and only two stepper motors are connected to the drivers. If that's the case how can you overcome the idea of two unused driver's slots so the shield won't fry. As usual you are very good at this, my hat is off to you.

How doable would that be? A minimal part dual Nema 17 3d printer does sound appealing.
