Nice video; helped me better understand how the lead screw mechanism works. A Scara robot, which doubles as a pen plotter is on my DIY wish-list. One thing I'm curious about is, how you deal with alignment of belts when designing; do you have to do a lot of measuring? Are you using CAD software? I don't have a 3D printer and am using hand tools on my current project, and there's a lot of room for error (I've had to re make parts because I measured or cut pieces inaccurately). I imagine getting things to align is much more important for a Scara robot than on my current mechatronics project (a Rubik's cube solver).
Belts are a bit tricky to get right because they always stretch a bit. I designed a tensioning mechanism to keep the belts under tension but yeah it’s a lot of measuring haha, I use FreeCad it’s open source CAD software, works great. A rubik cube solver seems like an awesome project good luck 👍
Hi. That's a great project and I'd like to make one. What sort of thrust bearing did you end up using? In the video you said there'd be a link to the 3d printer files. Did you forget to post it?

Very cool! You should make a video about the electronics, I would love to re-create this
Awesome video and great ingenuity!
This is Super Cool!
I would Love to Build One like this

That z-axis stepper might be noisy/skipping because it (looks like it) has weight on it perpendicular to the axis of rotation.
thanks for the idea. I am going to try and put a trust bearing on top of the stepper motor to take up some of the load
What grbl do u used,? Can u share the link of all softwire with more explained
I used GRBL v0.9 uploaded that onto the Arduino. I am going to update the stepper motor drivers and make a video on the electronics
Do you add Inverse Kinematics into GRBL?
Please lower the acceleration parameters so you will obtain more fluid movements, $120 $121 $122
Part details list
Nice video. Music is so unbearable that I had to switch audio off and I do not know if there were comments, but still, good project.
Sorry about that haha it’s hard to find good copyright free music
