Really need more info :
Please post the video as per post #267
First it was giving me this type of error. And i resolve it by adding an arduino.flushInput() string like that. Which i think is some kind of interrupt.
It works perfectly fine and scan all the cube, except the D-face. Even though i've added the same flush.input string.
kas:
"flushInput()" flushes Serial input buffer and discards its contents
This python function is renamed "reset_input_buffer()" in Python V3.x
which Python version are you using ??
which RubikKasBot (python) version ??
which CubeMover (arduino) version ??
You mean you can scan all faces except the last one ?? :o
I'm using CubeMover_13, RubikKasBot V1.3 and Python 3.4.2.
Yes. By adding a flushInput it start scanning, but now it stops on U-face instead. And i did't change nothing from yesterday. And if i change all flushInput with reset_input_buffer it's says that it was not defined, so does inputflush*. So it's a little bit confusing how it works*
Hello all ,
does anyone has the frame (stand) stl files for 3d printing ??
i 3d printed the claws from the previous posts and it works good ,
i saw kas support v2 dxf file but it seems not suitable for 3d printing ,
thanks
hey kas!!
long time no contact, i gave up on my project for a little bit there but decided my school might disapprove. might have some simple coding questions to come like if i could get away with completing the project with out a buzzer.
hey kas,
for your code for "Cube Mover hard coded Demo @kas2017\n" I'm having some troble as when i set the limits for closing the griper it works at the start and finish. however throughought the execution the gripers don't close enough, i can try provide video.
thanks

hey kas,
thanks for that i'll see if i can get a buzzer, but i should be able to run the code soon then.
here's a video of the cube, as you can see the gripper on the left is lose and the one on the right seems fine, these are what my limits are set to, i thought it might be because of the my limits being the oposite to yours (close is higher than open, yours is the opposite)
First make sure that your can manually increase claw closure
You may have reached the mechanical end stop of your left servo
Just unscrew, lift the driving arm and rotate it
i thought it might be because of the my limits being the oposite to yours (close is higher than open, yours is the opposite)
That's a possibility
Remove cube,
adjust DOWN/BACK_CLOSE/OPEN parameters one at a time and see the effect for yourself
For a good grip, without cube inserted, claw should close about 2mm more than the actual cube edge size and open 1 to 2mm more than cube diagonal
hey kas,
thanks, I'd already been playing with my limits, so I've decided to change servo and to add different cushioning thats more gripy as one of my gripers is able to grip the cube while the other obviously can't. I've also been drawing up to 2.5 amps during the uses, does what does yours draw?
thanks
that's strange do you know what the stall current of your servos are? but its no real pro blame I've just
increased my power supply
i changed the connections to the servos and they back gripper still doesn't hold the cube I'm a little lost about because the down claw holds the cube beautifully, but i did find that by prints aren't quite aligned so
i will need to upload a different frame for those that would like to use it.

With cube removed, can you manually close the back gripper ??
How is the requested applied force compared to the down gripper ??
hey kas,
ive managed to solve the problem with the gripping, the claws werent aligned properly and i changed the foam that i was using on the claws.
however, i am now having some dificulties with the python, here's an image
any chance you know whats going on there, i changed the path that you set and it still didn't work.
