Sir,,,I have copied and pasted different version of Configuration to Merlin folder.Will different version of Configuration will make error? and also I can't find written code of Stepper motor...
This channel have come a long way in terms of video quality and other aspects and I've learned a lot of things here and I'd love it if you could recreate your old arduino basic tutorials, Thanks for what you've shared with all of us and I hope you'll keep going
All your projects have been an inspiration for me and I'm currently developing my own smartphone controlled car, thanks for the amazing ideas!!! Great work!!!
With this laser power you should think about some enclose, it is enough to irreversible damage your eye within a glimpse. Also a fume extraction would be good because of the toxic gases and particles. Greets from an engineer who works everyday with lasers.
Hey, thanks for the input! Yeah, we must be very cautious when working with lasers. I already mentioned that in the video that safety goggles and respirator mask are must have. Cheers!
It’s great that you keep your collaboration with Dassault Systèmes to produce your legendary content. I can tell you that your rover video has had a great success among DS Enovia engineers. 👍
Can you do an indepth inverse kinematics explanation? Showing the steps how to derive the equations and perhaps doing another example for other robot design would be very nice!
I understand how inverse kinematics works in theory but I've never been able to understand how people use it on real things. I don't underhand how they manage to get the angles needed for calculations and I also don't understand how they manage to get the location of a partof the robot in 3d space
Hi Dejan, I downloaded all the build files from Cults. Where can I get the stl files for the case for the Arduino Mega + Ramps boards? The downloaded file only come with the Arduino Uno case stl files.
Just an idea I had after watching the start of your video, you say you dont need the 4th rotary axis on the end effector as you are mounting the laser there. Most of the lower cost diode lasers dont have round beam shapes and they give a rectangular beam spot, as a result you find they will give higher power when travelling along that narrower axis. My thought is if you used the rotary axis to turn the laser head you could keep it aligned along that axis to maximize power, most important when cutting with the laser. My other thought was this may not be too difficult if you processed the file to be used as though it was to done with a drag knife engraver ? maybe there is already software that will keep the head aligned for that purpose ? Anyway nice project !
Please make a 3D printer version video off this sacara robot. Getting rid off from the traditional 3d printer's small printing area besides occupying big place problems can be solven by this.
haha that was a good one! 🤣 Though, making a project like this requires so much work, starting from designing, building, programming, troubleshooting, filming, making a script, video editing etc...
that's a brilliant idea big bro, may i ask why you not use light burn for the software? i really love our design, maybe i do it for may laser engraver..
I had been eyeing this robot for a while but never could come up with a real use, now you have and now I'll probably have to build one... Maybe lol thanks
Can marlin support a dual setup? Sticking a laser module to my 3d printer extruder assembly would allow me to do both, without having to switch hardware?
How does the SCARA kinematics and homing logic in Marlin work out for you? Do you need any more changes / improvements to get everything working well? I introduced a “scara feedrate scaling” factor at one point to deal with the difference between degrees-per-second versus mm-per-second, and that should have an obvious positive effect on laser engraving. And I also have in reserve some alternative kinematics (to deal with XY tool offsets) and improved homing (Z first, to the top and “quick homing”) for a SCARA like yours (with a rotating base), originally made for the defunct MakerArm project. There is even mesh leveling. Some of those changes should eventually get integrated into Marlin. At one point I also repaired the old laser plugin for Inkscape, but it looks like the plugin you used is superior.
Hey Scott, thanks for the incredible work you put in the Marlin firmware. Just like I said in the video, I had some problems with the homing, I opened up a issue request on Github #22233. I managed to get it somehow working with commenting few lines just like explained in the video, but still it's not working 100% as it should be.
Hi Thank you very much for all the information. I have a question. Your Solidworks 2D drawing should prepare for zero and home point, and you had to look upside down so that, for example, the scara offset x and y will be 200, -120. What if you see the Solidworks drawing exactly right. Then the x + axis is to the right, the y + axis to the top and the z - axis from the screen to the top (the z axis will be the same). If we write the coordinates with this perspective to Marlin and change the limit switch pin to "+" except for the z axis (z axis still in "-"), should this work (x, y, z home direction is still -1 because we are approaching limit switches, but for positive direction this time for x and y)?
Hello, I am guided by this project to make my scara type 3d printer, however when I enter a G1 the robot does not move, while with the G0 it works as in the video, I do not know if you have any advice, it should be reported that because it is an arm the G1 should make linear trajectories while the G0 non-linear movements.
hi man i wanted to ask if you make curses where you build those projects from scratch like actually building all the parts in solid works and explaining the code in details ? great video by the way
Could this possibly be scaled up to run at a small workshop level to cut stuff like sheet metal? Looks quite interesting, only seen Scara printer prototypes before.
Hi, I need to read data of battery and show level in a display, but I wish to show in percent instead just volts. I’ve a eletric motorcycle, and the display show 64 volts ou 50 depends how I driving. But it’s confused because I never know if the battery is low or not. In percent is more clear. Can you help me ?
Hey, thank you very much for the coolest content. Creativity. Looking at your site, I noticed two projects where you use the same tool, laser engraving machine by "scara robot" and laser engraving machine by "simplest CNC machine", I guess the question, what is the use of laser in scara even though there is a simpler CNC machine that is easier to use and less expensive, but most of those interested in this field use the same idea of the simplest CNC machine as it develops. scara . is not used
Thank you for this great explanation)) could you please tell me if will be possible to change stepper motor to servo motor? Do I need to do any gears changes ?
Do you have a great Egg Bot ardunio uno shield robot with tool changer function? It is interest me a lot. Minimal 3D print as possible. Smaller eggs and maybe a strucc egg also. Maybe the tool can be laser or engraver head. Maybe you can figunting out something genial setup.
Hello, I am doing your project and almost about to finish it, it occurred to me that I could put an LCD screen with a card reader, but Marlin tells me that I cannot select 2 screens, the fact is that I do not see that another screen is selected , can you give me a hand. Thanks for everything
Hi there, I tried to test your engraver and encountered the following problem. When I try to home all axis, the Y homes nicely(while the X is moving away from the endstop), but then the X skips entirely and proceeds to the Z axis. If I try to home the X manually, it works perfectly. Do you have an idea, why that could be? Thanks in advance!
I'm improving your project to be an all-in-one machine but the more I go on, the more I notice some flaws: -The vibrations and the inaccuracy are due to the accommodation of the thrust bearings in the joints which block only the first millimeters causing translation during movement. - Marlin was not well implemented, it has a dedicated laser mode. -In the parts list you forgot to include the 30x42 ball bearing. apart from these things congratulations for being able to assemble without modifying the pieces and using only 3D printed parts.
Great job :) Do you think that firmware will work with more recent 32bit board like BTT skr2 or octopus , i think it will be better linear or circular interpolation that is not really possible with a mega2560.
To go further with the application of this scara arm ( like found with Fanuc industries ) I guess it's not imposible to make a version for 3d printing. Good work as usual keep us amazed!

Great work. I also want to work on this and add changes to it like I want to add camera (opencv using python)to marlin firmware. Can anyone guide me on this
fantastic, as always! thank you for going into so much detail, i really learned a lot and feel like i could follow along. always amazing when you post a video! see you next time!
i have only 1 question you added 4th motor in the laser head, for what? i think with 3 motors its enough maybe i wrong im just a student. also i liked the video
hi, i have a problem with homing can you help me with this issue. i used the firmware from your site but my issue is y homed first but when started to move towards endstop y also rotates but it should be idle when x is homing as you shown ,someone please help me with this issue

You could apply s-curves to the motion to control a lil bit the backlach of the belts and smooth out the trajectory.
Thanks man! You rock! I've been hoping for solid works to be more affordable.

Incredible! This must be one of a kind? I've never seen this type of laser before, this has capabilities that no other laser has :-)
Glad to hear it, thank you!
can you please make a video of its parts briefly, from where you bought it and how you did the complete programming the brief video🙂
Hi Dejan,
I downloaded all the build files from Cults. Where can I get the stl files for the case for the Arduino Mega + Ramps boards? The downloaded file only come with the Arduino Uno case stl files.
Fantastic design. How would the electronic part be changed, if you had to drive NEMA 34 controllers instead of small NEMA 17 ones?

Given the many degrees of freedom of the robot, would it be possible to engrave ona 3d surface of an object, like the sides of a cone?
You should teach up how to make a 3D printer/extruder.

Hello, I want to make this really nice project ! But seems like the link to download the Stl is dead on the website. Thanks in advance!
Which language is supported in Arduino? First which programming language do we have to learn to program Arduino.
nice! you could mount the robot above the material which would give you full 360* freedom
That's cool idea!
how much weight can support the arm?
do you think i can swap a more powerful laser module that weights 360 g?
Bro u r working hard superb 👍

Nice. That said - the arm looks very wobbly. Did you measure the play?
Yeah, it's quite wobbly. I don't have exact numbers but it's few mm for sure.
What are the transmition ratios?
i have only 1 question
you added 4th motor in the laser head, for what?
i think with 3 motors its enough maybe i wrong im just a student.
also i liked the video
