Hello, can you make the first issue of arduino rc remote control?

[@VijayaLakshmi19807]

Sir please make a simplest 3d printer... cause comeon... its 2021! 3d printer is a must nowadays. Love from India❤❤❤❤❤❤❤❤❤

yes you can use for fabric also.

Followed this guide & built my very own engraver today! I was able to convert the drawings into stls & 3d print all. I had to change a few things to get it to fit / work. But overall Happy! I'll make a video

[@VictorHeineken-ug1kv]

I have a question: Do all the materials/parts come with the code included, or do I need to add it myself?

[@skykalaicreations]

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.

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!

[@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!

[@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!

[@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.

truly the highest quality content, you never fail to deliver. I've been wanting to make something like this myself for a while

[@HowToMechatronics]

Thank you! Go for it! 😀

[@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.

[@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.

[@mohixx117]

You are back!!!!!!

[@OGMann]

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.

[@AugustineAriola]

The finishing is really impressive. You just need two stepper motor for x and y direction with no moving part along z- axis. It is really compact and cleverly built.

[@spaceengineersmods]

You can even reduce xy to CoreXY-like principle and have no moving Motor at all

[@theofficialczex1708]

@@spaceengineersmods I've built a similarly-sized core-XY plotter, but I utilized many 3D printed components.

Can you tell us more about stepper and driver spec.?

[@HariniPada]

Super excited to give this DIY laser engraver a try! Looks like a fun project to tackle 🔥💪🏼

[@TinyMaths]

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]

Glad to hear it! Have fun building one.

[@lawrencetate145]

Wow. I hope these talents become part of grade-school curriculum.

[@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!

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?

I've built my own CNC. The problem with this type of design is that is that the shape makes it wobble if you want to go faster. It's like the end of a fishing rod and the faster you go the worse it gets. So a square frame is a huge upgrade.

[@electronic7979]

Excellent product

[@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.

[@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?

Just to verify; Will this machine CUT modestly thin airplane ply (balsa, birch, etc.) & XPS foam with reasonable accuracy or resolution? These materials aren't thick or very firm. I can use a foam cutter for general shapes, but I'd like to use .stl files for gcodes to cut pre-designed shapes from folks that have already 3D designed said parts such as wing ribs, formers & similar. I'm just a home hobbyist that dabbles in electric prop & EDF homemade/DIY model RC planes in XPS foam (Depron brand), 3D print & light ply. You're designs & builds are killer nice!

I Really loved it And Always well explained

[@HowToMechatronics]

Thanks!

[@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!
