This videos is about modifications that turned the EleksMaker machine into a better performer than the already amazing 3D printer. First I 3D printed belt holders and adjustable roller mounts for the X axis to ease all movements. Then I equipped a small-dotted 405 nm laser diode, to improve on fine details. Finally I replaced the Pololu A4988 stepper drivers with Watterott TMC2130 ones. All the advantages of these Trinamic ICs will not fit in this text field. - วิทยาศาสตร์และเทคโนโลยี

Wow! Really great Upgrades! Very impressive. Especially the Trinamics Driver.

Now you can add sounds so it can do a *pew* *pew* *pew* sound when it is active and they won't be drowned out by the stepper motor sounds.
lightsaber sounds would be more appropriate than "pew pew pew"
I used your printed upgrades. I had to do a little hand filing, but that was because of the tolerance of the 3D printer I was using. I was not going to reprint it when 5 min of hand filing got the roller to spin free. I now can't wait for my drivers to come in. Keep up the fantastic work.
I can listen to you talk about anything and it's always as interesting and relaхing.
You're most likely the best maker-engineer I've seen on TH-cam.
After playing with Eleks for quite some time I improved quality drastically by placing an adjustable Z axis. I was never been able to adjust focus manually to get good results with that kind of laser untill I installed it.
LOL! Wow ... a CNC'ed Wood case for the TS100 solder iron .... you Rock !!! :) this is called upping the game!
That was so freaking cool to watch. I love upgrade/tinkering vids like these! Cheers and happy holidays!
Very nice and in-depth video! Got to know many small things about which had no clue about. The Trinamics motor driver seems like a huge upgrade / improvement over the stock drivers.
Hi Marco.
Thank's a lot for this movie. I have the same model od Eleks Laser, and I have the same problems as You. All information you present is just a hit. I'll try to rebuild and improve my Eleks Laser too. Thaks!
Dude this is awesome, the precision is just beautiful.... And think of what one could do with this type of tech!
Great pro tip I got from that was using a breadboard for soldering pins to pcbs. The rest of the video was also very informative of course.
This is a fantastic video. I'm looking forward to seeing how all of this is done and how to configure it. I just bought this same machine and am following your upgrade path. Please put a configuration video with information on how to do it!
I have the same machine but you took it to whole another level. Congratz
That is incredible performance - great work! I still believe the silence at 6:34 is a trick though! ; )
With this level of precision, you could probably laser-print your own mechanical stop watch!
An idea for the next use: Strap a tiny camera to it, and extend the lens with an extreme macro ring so you can do huge resolution microscope scans of larger objects.
Machine vision cameras with the "100X/200X 2X Barlow" fake C-mount lens(commonly found on eBay, and is not actually a microscope) work extremely well for this purpose.
A super-resolution algorithm implementation would also be quite nice, it's done commonly in the thermal imaging industry to quadruple the effective pixel count via small hand movements.
Yeh, beautiful idea! I already have nice "h264 built-in" camera that gets huge resolutions at high frame rates through USB 2.0. Will take a look at that lens.
And then combine image and original picture for QA purposes. Derive the difference, and instantly spot and identify possible or actual faults! Woohoo!
That idea really reminded me of Microsculpture petapixel.com/2016/04/25/macro-photos-made-10k-images-captured-microscope-lens/
Thematically a bit off but maybe some of you find it interesting.
Realworld DRC/ERC :)
AOI :)
It's a common step in PCB fab.
Merry Christmas and thanks for a brilliant video. I have to investigate getting this machine, upgrading and etching PCBs. The time saving alone would make it worthwhile, not waiting for couriers.
Hi Marcos, thank you very much for contributing the improvements for the EleksMaker. I hope you see this comment because I see that you have some time that they do not comment or ask anything about these updates. I had acquired this machine about two years ago and had to keep it because it was very busy, but now I decided to finish it so that I could use it on printed circuits. In my case it did not go very well. In the case of the Beld Holder and the adjustment of the X axis it worked perfectly; but I had problems with the operation of the TMC2130. I made all the connections step by step and I have reviewed them very carefully several times, update the GRBL to version 1.1, make the change of the configuration of the parameters that you have provided.
When I start to test the machine, and I try to move the X axis, I notice that it works well; however when I try to move the Y axis, I notice that it does not move. Then he proceeded to move the potentiometer to increase the current and setting the potentiometer to maximum power, the Y axis tries to move, but it does not, however, if we help the Y axis move with the hand, it begins to move.
I have tried to contact you by mail, but it has been impossible because I have not received an answer, so I am writing here to see if I am lucky that you see my request for help ...
I do not know which was the GRBL version about two years ago, maybe the problem is that I have the RGBL 1.1 version installed, and now it is not compatible with the software residing on the Arduino Mini Pro.
Please send to me a email to electrologia@electrologia.com.
Thanks very much.
Awesome.... that led in the end did it... magic...
Great research. Very impressive performance. Thanks for sharing!
Wow!! those modifications worth a lot!! Great details!
I'm glad you used the voting system on the TH-cam community features to help you decide what video to make.
Wow! Super quiet! Very well narrated!
Now this is the first video that eradicated all my doubts in purchasing a TMC driver.
I'd like to purchase them too.
Wow nice to know before buying, thanks. Those stepper drivers are wonderful
Great job with the precision and silence. Thanks for sharing your steps. Can you let me know how well a PCB etched using the improvements?
Hi Marco, great video, thanks. Now you got me wanting to make one.
Do you plan on doing any more of these? It is really cool, and you seem to be one of the few that have pushed it this far.
I have two of the TMC 2130 coming from them myself this week.
Do you have a picture of the final results in high res? Wonder if you still see the edges from the steps
I ordered all of the stuff to do this. I've done etch resist and light tanks - it is a giant pain in the butt and doesn't have a perfect success rate, and definitely can't do small traces. Needs a darkroom more or less too. Messing with high pH solutions isn't nice either. I was messing around with flatcam, I think it'll work with this method. Can do isolation routing from a gerber file, and export to SVG, which could be imported into laserweb. Flatcam looks like it can generate gcode too, but it's more oriented towards CNC milling. Would have to edit the gcode to switch the Z layer movements to turning the laser on and off.
Thanks for these videos.
Merry Christmas !
Very interesting video. Everything ordered and printed justness to wait for the deliveries now.
Do you think that this - www.banggood.com/EleksMaker-EL01-500-405nm-500mW-Blue-Violet-Laser-Module-with-PWM-for-DIY-Laser-Engraving-Machine-p-1179513.html?rmmds=search&cur_warehouse=CN - would be a suitable replacement as it would not require the PWM modifications ?
The oscilloscope outputs at 4:43 from your drivers are exactly the same as a "class a" audio amplifier (or likely "class ab" on the left) vs a "class b" audio amplifier (on the right). The cross over distortion (or in the audio world THD) likely influences stepper driver movement in the same way as it does a speaker driver or our ears. Hence being more quiet and having fewer artifacts.
Interesting comparison! I wonder if there are any technologies in the Trinamic driver that could benefit HiFi amplifier ICs
Marco Reps More likely it is the other way around. The trinamic chips or stepper motor drivers of the future can benefit from reduced distortion methods of audio ICs or discrete components such as Darlington pairs or negative feedback loops.
I saw the same thing and and thought it was odd to see that since it's usually something you want to avoid which talks about the design quality of the cheaper driver, but yet again this was not an audio application so one can kinda understand the desition
Well err, not quite a legit comparison. Speakers are essentially (ideally) a resistive load being driven by a voltage source (Class AB or Class D). Steppers have a significantly greater inductive component and are being driven by a current source. The feedback loop in an audio amp is controlling the amps voltage output whereas the stepper driver feedback is controlling the current that the stepper coil is allowed to ramp up to. If the scope is showing only voltage across the stepper coil then that's not the whole story....
That's a very nice case for the ts-100!
The TMC2130 are amazing little things!
i didnt even know the made such drives! they perform amazingly
Excellent tips; thanks.
Did you fix the issue with the laser firing upon controller initialisation? I have the same issue. I originally assumed it was a floating pin that needed a pulldown resistor but haven't found time to investigate yet.
That trinamic signal was beautiful
Your listening to smoooooth cnc on 95.5 the coyoteeee.
My listening? What about the other guys' listening? What about your listening?
@@Anvilshock infinitely more subtle than I would have been. Brought a smile to my face!
Oh wow. I wish I could learn from you!
Sharp! quite impressive.
Yeah those trinamics are a beast of an IC
Oooh... Nice re-work!
Now you need a 10w laser and a set of lenses that focus like a phone camera stack, then you can adjust power based on need, and adjust the focus to save time, vector drawing is a must for that of course
If you leave the plastic wrap on the acrylic and paint it black, you can cut or engrave it. The black paint absorbs the energy, instead of just going through and bouncing of it.
Damn I have that exact laser kit. I am so ordering that diode and triodes
Wow, this is amazing. Thank you!
Hi, love the video, did you design the adjustable rollers yourself? if so could you share it with us? thank you.
Excellent video! Thanks for sharing. I am still very new when it comes to Lasers and or 3DP. I have just started dabbling with CNC very recently and built myself a 2ft x 2ft mpcnc with Marlin 1.1.9 and learning about fusion and g-code and my next plan is to move to laser. I am curious to find out if this TMC2130 based controller can benefit CNC routing applications for say milling Acrylic??
Amazing mashine and nice work
Awesome job, thank you, having a similar setup now. Did you ever concidered to use something like a DLP Printer for it?
Thank you, awesomely useful video!
Muito top, sua explicação é muito boa! Parabéns!!!
Interesting project
Thanks for sharing 😀👍
Awesome video. Can you do an entire video on those drivers. Very interested in how they work. Would like to see them on 3d printer
thomas sanladerer also made a video about them in 3D printers specifically
Marco Reps I really like the fact that you showed the effect visually with the oscilloscope. It's one thing to to say it but seeing it was great. I am not sure if you could show the other features visually
I don't understand anything, but liked your video. Almost Discovery Channel. Thx!
Have you tried using the current sensing capability on the Z axis of a 3D printer? Sounds like the right way to do bed leveling
Tanks Marco, very usefull. Listen you regulate the Vref? Value? By and apreciate.
too amazing real germany engineering upgrade ! thx for share !
Hi, You did a really good work. Surely this will help to all interested people. Well done mate. The only thing is the link in description for wiring and software upgrades isn't right. Would be possible to share the actual link. Would really appreciate it
Very well done sir
Magic. Excellent info
hello.
thanks for sharing the vid. I've got a 1x1m eleksmaker. I see u have a transmission bar that let u move simultaneously the two sides of the main transversal harm like u have 2 motors. Was that a mod of your or it was a stock configuration? I'd like to add it to my machine because of is big and needs it in order to avoid the torsion of the central harm.
thanks
Now I really want one.
Nice upgrades! May I ask what precision can you achieve with that motor driver?
WHAOO thank you Mister Marco
Basically a 300 euro super silent super precise Cnc base :D pretty sick
"SUPER FANTASTIC" Bruno from the movie Basquiat :D
Try putting a 0 ohm resistor at R4 on the Pololu board and check if the zero crossings are gone
The Trinamic drivers were probably the best upgrade for my 3D printer - Delta printers are especially noisy with four motors going constantly; now all I hear is the fan noise
pretty cool laser machine
That is getting insane, that you can do that at home
Great Video, did you Change the Software to create the gcode? In the other Videos I saw that the laser is just doing linear movement and in this case the engraver is doing line by line also with curves what I would also prefer for my engraver.
Wonder what power laser is required to etch a standard copper clad board, if they make even a small desktop laser pcb etcher they will sell loads of them to hobbyists and businesses for rapid prototyping
Hi! Could you provide some links to the 3D printed parts? Thanks!
Thanks for sharing 😀👍
1. was hast du gelernt?
2. was arbeitest du?
Ich wünschte ich hätte Talent in Sachen Strom und co..... aber wir hassen uns 😄 Habe einen 3D Drucker und das piepsen der Motoren treibt mich in den Wahnsinn 😄 Respekt vor deinem Know How! Neid!
заказал TMC2130. Очень понравилось как двигается каретка :)
Thank your for the video!
I will maybe check the stepper driver out.
But since im a total dummy with these things, it will stay with the normal "single mode" and Im not going further ^^
Also that sound comparison was wild. Do an ASMR video.
you make amazing content
oh man, this motivates me a lot to pimp my machine a little.
Can you post some details about the 3d printed parts and the end stop solution and spi interface you built?
Ok, got the link from the description. Dankeschön.
Google thinks the site is dodgy, but will allow me to go there :)
I have a cheap Chinese CNC machine and i have been thinking of way to make it accurate enough to mill a SMD PCB. So far i was only focusing on mechanics however after watching this video i think i'am gonna have to have a look at the controller board. microstepping might just be the solution to my problem
nicely done
Thanks for this video, it's great! I'm interested in using this for pcb boards with more than 2 layers, any advice for materials? Definitely going to buy one of these machines this week and going to buy those drivers. Going to test out the alternative laser diode you listed too, just to see how good it is.
I don't get why he showed that at 1:55 but decided not to use. The 1W laser diodes are cheap, if it is possible to use them to engrave PCB ink as he did with the pricey one would be just great :-)
Also, FIlastruder now has these in stock on sale for $12.99 USD
Great video! Sure would love to know how much all of this cost in total though.
3:42 did you just yank drivers out of a powered board 😱
I'm making a small office plotter and need it to be silent so I picked up some tmc2208. I made sure to get the freewheeling protector boards to try and save them from the ignorance of the suits.
Nice video, funny (at 1:09-1:10), direct, voice totally understandable, congratulations! May I ask why you choose not to use the 1W laser diode at 1:55 to do the PCB engraving?
I am thinking on mouting one of these beasts using a similar laser like the one at 1:42 but using Acro System Openbuild parts, and arduino uno with cnc shield, as it runs grbl just fine. It would cost, without the laser, about U$100-150!
I have the same engraver (well, the older iteration of the same engraver) and have always had huge problems with jagged (and I mean really jagged) lines. Think these stepper drivers could fix that issue for me?
Fantastic monopoly logo dance over wood XD XD
Did I miss the video of you making that wooden soldering case? I need to make one of those!
The manufacturer sent me that a while ago, I don't know when / where / if at all they are selling it
Marco Reps when seeing that case I fell in love with it - would be great if you could pass a link as soon as it's available!
PS Great video
If you google for 'Logend wooden box iron box TS100 smart iron wood box' you will find it.

The manufacturer sent me this link: www.ebay.com/itm/162776351409
Marco Reps thank you so much!😊
Hello! Awesome video! I got one of this machines and your video is absolutely relevant!
Woluld you mind to share the file to 3D print the pieces your showing in it? Will be great!
brilliant indeed !
Wonder if the Watterott /Triaminics driver would work on a Carbide 3D Shapeoko 3
Thanks for the video very interesting!show us what software you use to get from Gerber or image to Lasered copper?
FlatCAM
265 steps? I guess you mean 256, lol. I love how silent they are!
Is there an higher current version available?
Damn, German influences ... we say zwei-hundert-sechs-und-fünfzig = two-hundred-six-and-fifty. 2^8 should be the international standard :)
Marco Reps. Haha I know the problem very well (in Dutch). It's even a bigger challenge when you need to go back and forth on a daily basis. Great video as always btw!
Be happy you aren't Danish ... imgur.com/PhmSI5a
Do you know how Late it is?
I was wondering how the stepper driver are providing the better performance. The controller is sending a pules when a step is needed. The only way I can think of is that the stepper driver introduces a delay and therefore smoothing out the timing errors. Futhermore I think you can see it in the results! Because there you see that not all forms are completely closed. This can then be explained because the laser introduces nearly no delay. Any other ideas?
