- เผยแพร่เมื่อ 5 มิ.ย. 2024
- Today is day one of our DIY Laser Engraver build. In this video we will build the entire CoreXY motion system of our laser engraver. Many of the parts are 3D Printed and will require a 3D Printer. This same frame can be used for vinyl cutters and plotters. This is a quick project and can be easily completed in a weeking with the right tools.
WARNING: Lasers can be very dangerous and extreme caution should be exercised when attempting to build this project. Understand the risks to you and others by building a project like this.

Will you be building your own laser engraver?
Someday.
In the middle of it right now! It does take some time to print all the parts out, especially if I screw up here and there.
I am planning this build. I would like to reduce the size of the footprint to 250mm square since I only plan to engrave small images. Can I downsize this project?
Sure can. Just shrink the rails and extrusion. Update the firmware with the new size. Everything else is pretty much the same.
@@MakersMashup Thanks for your super fast response.
I think I will build one, when I am ready with my x301. Thank you for the great content.
Building one now. Just need to get the laser. Had a bit of trouble with the placement of the xy brackets. Had to watch the video a few times.
Great job on the build. Keep them coming.
Excellent video! im on my way to watch part two before i build my shopping list... oh wait, you did that for me! Guess theres nothing left to do but order parts! thanks for the amazing video!!
This is awesome, I just purchased a 10W (output) laser and needed something to do with the 5.5W Thank you for this
All I gotta say is you are extremely smart to do these things on your own
Outstanding build
Excellent video well detailed and you named everything I love it. People need to take notes
This is exactly what I was looking for at the perfect time! Thank you for doing this series. Soon as stuff is finalized I'll be building this.
I think I may build this for the wife. Thanks Rob!
Very interesting project-Thank you✅
Great how to video. Very interesting.
Great work.
Nice timing, Going to convert my Powerbelt Zero into a laser engraver!
Thank you very much, sir for this! Your video is my source of my project’s assembly.
I wanna ask you, are those 3D printed parts are editable? I want to rearrange some screw holes because my mechanism has a slightly different shape (H-Frame)
What steppers drivers are you using on the SKR? I would think microstepping would work for the fidelity you want if you use a 1.8 deg stepper motor with say a 2208 stepper driver..
TMC2209's
Do not look into laser with remaining eye.
Does the Rear Corner Bracket Top...the part that the extrusions lock into need supports when being 3d printed?
Nope. There should be a support in there already if I posted the right model but the 20mm gap is easily bridged with most printers.
Depending on the BOM cost, I'd love to make a pen plotter with this. How many grams of plastic did you use?
Didn't track the plastic use. For just a plotter you could probably do this for $100 to $200. If you went 8 bit board and ordered cheap rails. Those are the two largest costs aside from the laser which you wouldn't need for a plotter.
What is a ballpark figure to build this project excluding the printing (I have a very large collection of filament)?
I would say somewhere in the $250-$350 range. The "Laser" is the most expensive component on here. The one I bought clocked in at $179 from amazon.com. It is really going to vary a lot based on what parts you buy. I'm using an SKR but you could use an old Melzi 8 bit with drivers already on it.
Hi, can you recommend the frame aluminum extruded parts you used? I've been looking on Amazon but it seems they're not that clear about the specs.
In its Bill of materials document, he mentioned 4 aluminium extrusions of 400mm length that you can either choose as 20x20mm section (aka 2020 extrusion) or 20x40mm section (aka 2040 extrusion) if you want a beefier frame.
I'd stick with 2020 the models were not designed for 2040
I have downloaded the .stls for this project. I can't seem to find the pieces that clamp the belt to the CarriageBeltBody. How is it labeled? Thanks for all your hard work and great video.
Did you ever find these? I can't seem to find them either.
@@MrBcm77 yes. It was in the list of stls. I don’t remember what it was called but I do remember that there was a left and a right model.
@@MrBcm77 Found it !Carriage Belt Plate Left and Carriage Belt Plate Right.
@@howardmandel7930 Thanks
Rob, do you plan to release any more X501 videos, or was the one you did a "what's different from the X301" video and the rest is just an X301 build on a bigger frame?
Yup just working through some things and needed a break from it.
More videos are coming.
This is an interesting project, are you planning an enclosure for laser safety?
Right now no. Long term yes. I'm planning a set of videos on building Enclosures for the X series printers which will be easily adapted to this. I wanted to put a plexiglass shield in front but if you've priced out laser safe plexiglass you know a large view window will cost as much as the build itself. So safety glasses it is for the short term. 😔
@@MakersMashup Invest in a good pair of glasses :) check, I am thinking this might be s nice edition to the lab, so I dont always need to run to the maker space to use the 100W CO2 :)
@mikey's Lab - Getting good glasses was the first thing I did. Couldn't agree more about safety. Bought a pair from a reputable US vendor and confirmed the wavelength was covered as well. I also run the laser with a web cam as much as possible. One of my largest concerns on these types of diode lasers is bleed into other wavelengths. Unfortunately no way for myself and most people to confirm the actual wavelengths the laser is emitting. I've seen from other YT channels that wavelength bleed into IR or UV is not uncommon and safety glasses may not cover those bleed wavelengths. So I limit exposure as much as I can personally. :)
Could I use nema17 1.8 motors instead of the 0.9 ? Thanks for a great project !
Probably but your .9.will likely provide a smoother cut in arcs.
@@MakersMashup Thanks, I'll fork out the cash out for the 0.9 steppers. The 1.8 are much cheaper.☺
3d Files does not contain main carriage. Do you know where I can get it? Building one of these 600x600.
I'll add that to the files, wrapping up the second part today
A 20x20 calibration cube
That’s freakin’ hilarious
Who ever thought a calibration cube could have a use beyond what it does
You are a genius sir
I didnt feel so smart looking around the shop for something to be a place holder there. I almost built something but stopped when I realized it was a 20x20 cube. :)
@@MakersMashup These work better: www.amazon.com/gp/product/B08HC95XD2
Tap the end holes (M5) and these lock the extrusions nice and tight.
I've seen those before. Didn't think it was a necessary expense given the bracket itself is doing the heavy lifting. Haven't had any rigidity problems at all. Thanks for the tip however. 👍
So I am working my way through making the parts for this project, and I don't see in the stl files the part that secures the belts to the Carriage Belt Body. Am I missing something? I do see the cable retainer but it does not look like the part in the video.
They should be there but I can check. The X301 has the same parts in the repo but I can check for you.
Carriage belt clamp here is the same model bitbucket.org/makersmashup/x301-models/src/master/STL/ I will check the repo in the am. Thanks for letting me know.
Is it possible to get STEP or Fusion 360 files for the XY_Bracket_Bottom_V2? I need to make mod a low profiled version. Thanks.
That file is in the X301 repo for the printer version. Both step and fusion are available
So I finally got all my parts in. I'll watch it slowly but is that one length of belt?
You'll need about 2.5M each belt. That will be a little long but 2M is not long enough. 2 Belts, upper and lower.
In the BOM spreadsheet, it says two linear rails are required. Should that be three?
Yup, you're absolutely right. Typo there which I have corrected. Thank you for pointing that out.
@@MakersMashup Oops - was I looking at the wrong column? In any case, this looks like a fantastic project. Gonna start collecting parts!
I'm missing a file in your thingiverse file
To fasten the belt
Why don’t you use end stop for X & Y? Thanks
TMC2209 drivers are used and they support "Sensorless homing". When resistance is met on the X and Y axis, the steppers report back to the firmware the limit. Z needs higher precision so that still requires an endstop.
Can you give some hints as to how you printed some of these parts? Like orientations, supports, etc?
None should require supports. Most orientations are self explanatory. The motion system on the build is the same on the X-Series printers. The print guide for this is here wiki.layerfused.com/en/X301/printing-guide
@@MakersMashup Well, self-explanatory for a seasoned 3D printer operator, maybe. Thanks for the link!
Fair point. None of them require supports. Usually you can rotate and get an orientation that works well. I believe most just print as is. Most also have sacrificial bridges so they will print better and the corner brackets gave built in supports.
@@MakersMashup Thanks for the info. I tried printing a corner bottom part and, since I'm a 3D nube, I chose supports. They were impossible to remove, so I tried another with none and it printed fine but one side of the print was really tight on the extrusion. I think among other things I printed too hot. I am going to try to tinkercad a tiny bit more room there and maybe try to design in some brass threaded inserts, too. I just think they are so cool. So much to learn about this, I had no idea when I started.
I really want to! Oh yea...First!
I'm missing the parts to secure the belts to the carriage belt body ?
Never mind, I found them (not in the engraver repo though !)
Glad you found them. I'll update the repo today. Apologies for the oversight
What's you Thingiverse name so I can follow? Great simplified parts!
www.thingiverse.com/thing:4762541 is the parts and rwmech is the name on thingiverse.
Can I use grbl control instead of skr 1.4 ?
Sure can.
You'll need a different firmware though. But figured you knew that.
I wish I could redesign parts for a better quality idler. The only idlers that fit are cheap ones, 9mm high, good ones are 10mm. The cheap ones make a horrible noise when they move.
The fusion files are available in the L301 and the X301 bit bucket. Can modify for your needs.
@@MakersMashup I can do very simple things in Fusion, but I'm afraid that's beyond my capabilities.
For the life of me i cannot find where it indicates how long the extrusions are. I have 1000 mm lengths i need to cut. let me know and thanks! Good work
You can make it just about any size you want. The only real limitation is going to be getting the belts tight. 400mm is the size I used in the video but if you want a larger one 500 or 600 should be fine. You'll need a belt that is 2.5x the length. That might be harder to source unless you go with a custom cut gates belt. Totally recommend them if you can get them economically.
@@MakersMashup Okay, thanks for getting back to me so quick. I'll cut mine to 400mm.
@@MakersMashup One more question, i dont see the belt retainer STL that attaches to the CarriageBeltBody. I can make it, but i'd thought ask real quick before designing it. Thank you
It's available in the x301 repo. Let me get a Link for you.
@@MakersMashup never mind, i wound up designing it so i could finish this build.
Where's part 2 and so on? Please
Releases this week. Hang in there
