    For the thermal switches, you can easily put an LED with a resistor in parallel with each thermal switch. If a switch trips, the appropriate led is going to illuminate, so you can find which thermal switch tripped.

    Thank you for the backlash segment of the video and upcoming joint testing! Great job putting this together, I will definitely be watching the upcoming videos on the further testing/design iterations! One idea that hasn't been addressed with 3D printed gears on youtube (yet) is applying a wear coating to the gears (something like a low-friction paint) - to allow tighter tolerances for less backlash without significantly increased wear rates. I think this, combined with grease, would be a really interesting long-term test after the upcoming individual joint/force/wear tests!

    Nice clean looking build. I've become quite partial to timing belt actuators to avoid the high backlash from 3D printed gear actuators. When properly tensioned, timing belt actuators have essentially no backlash, and only a little deflection under load from belt stretch. With some gravity compensation on the shoulder joint, you could also get away with a lower gear reduction.

    TIP for Everyone, if you print hollow shells; you can pack them with glass-resin, to save time and increase strength !

    It looks very nice. The PCB tower looks cool but, I am afraid that the motor drivers are going to get hot, maybe heat-sinks should be added and a fan for the enclosed space. Backlash seems quite high, but I'm waiting for the next video with more advanced movements to see how much it oscillate when it moves.

    With the metal acting as a thermal mass, it might still melt if the melt temp is reached on the motor. If you set threshold lower, then it will take a long time to turn back on.
    It seems like eventually you'd use the thermal switch as a failsafe only and calculate the safe duty cycle which would always be in effect?

    Holy crap that's glorious! Would 5 axis be good for getting cool shots with a camera? My brain sucks at figuring out the potential movement paths lol. If it is then a cool idea might be the ability to add keyframes for setting up a movement path. Maybe a rotary encoder to first dial in how many keyframes you want, then a button to set a keyframe, and a little display to show you how many keyframes are left to set as you enter them.

    Two ladders or a few 2x4's of wood, with rails on the sides of them to create a x and y axis, with a spray painter on it. You can place it against a wall like a ladder normally would, and hit PRINT, and it either coats the entire wall in controlled even passes, or draws a photo painting from a file you send the gcode.
    Cost? could only be just a few dollars if anything, if you already have the basic materials.
    Use it to become a tireless exterior interior wall painting employee that you only pay with buckets of fresh paint.

    Is there a reason you stepped back from using BLDC and stepped towards stepper motors?

    • @Skyentific
      @Skyentific  2 роки тому +4

      I am not stepped back. I still plan to use BLDC. But BLDC controllers way more expensive than stepper controller (around 100$ for BLDC vs around 12-20$ for stepper). So with BLDC, 5 axis arm would cost 500$ only for electronics. So to keep everything cheap (as many of my viewer require) I used steppers.
      But I have several BLDC projects on which I am working now.

      Without screw and nuts it cost around 150$ (if you use cheaper drivers from 3d printer). Each motor is less than 10$, all the bearings is less than 40$. And you can get stepper driver for less than 10$ per driver (I use here more expensive drivers 20$ per driver).
