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!

[@StigBSivertsen]

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 :-)

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!

[@HowToMechatronics]

Well I plan to make such a tutorial as a website article, but I lack time to do it any time soon.

[@risingmermo]

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

consider flipping the arm upside down and mounting the base to the bottom of an arial support bar. this will give you the full 360 workspace without repositioning

[@ТимурАскеров-ц1ь]

I can't understand what size of the working area turned out in the end, if measured from the base of the manipulator?

[@JVDColin]

I am a complete beginner when it comes to this stuff, I was wondering, why it is you use Nema17 motors, I was looking at prices and I could find "Nema 23 Bipolar 1.8deg 1.9Nm" for a similar price. They have way more torque. Is it because maybe the drivers and powersupply they require are more expensive? I just wonder because at the end you say the arm does have quite some backlash, so I figured that more powerful motors might help with that.

[@thebigboss4749]

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.

[@Prophetsarkar]

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🙂

[@AustralViking]

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 !

[@abigail_mcleod]

am always amazed by smart people :)

[@kelvin6k]

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

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.

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 ?

[@HowToMechatronics]

Hey, thanks! Well it depends what kind of servo motors. It is possible of course, it completely changes the whole system, the drivers, the code etc..

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!

[@Stolnikk]

Интересная вещь. Станочек класс. Спасибо за обзор.

[@ScottLahteine]

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.

[@HowToMechatronics]

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.

[@proto_hexagon5649]

15:35 Cura work with scara mode?

[@Aeren1982]

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!

[@Mayankkleo]

Wow , it's very interesting project

[@arthurmorgan8966]

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.

[@HowToMechatronics]

Sure, why not if designed properly.

[@mohammedmaaz3543]

Bro u r working hard superb 👍

[@harungungor8938]

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)?

[@chriswoods9857]

Ok so I am confused and maybe someone here can help. I have been working on a diy laser for several months now. I have watched numerous videos on how to achieve a working laser but haven't figured out the firmware. It was my understanding that I need 3 wires for the laser being 12volt plus, 12volt negative and pwm/tty. I won't go into detail on how I have been trying to get it to work, but I cannot figure it out. Just lastnight I decided to scrap the idea and actually buy the controller needed to work around the install for grbl. I was using a skr mini3 v3 to control movement and the laser. I tried different configurations with Marlin and nothing has worked. I get home from work and sit down to youtube as normal and this video is suggested to me. Did I just come across what I need to finish the build?!?! My question is, do I not need the pwm wire? And was there no setup in marlin for the laser control? Is it that simple?!?! I have been killing myself trying to figure it out! I know this is a year old but I don't think much has changed since this was posted as far as firmware goes. I hope someone can help me so I don't have to spend more money on a new setup. Thanks in advanced!
