Today I just manage to run the robot arm, after I calibrate @ Rest position, I tried jogging but notice weird scenario.
1. I jog J1 for +/-10 degree, the J1 move none stop to left/right (depends on i press + or -), I need emergency stop it
2. I jog J2 -10 degree, it moved as expected, I jog +10 degree it no moving. Same with J3
3. There is others issue but I think come from same root cause.
Then I notice at Main Control J1-J6 all the degree keep increment eventhough the robot is not moving and I no perform any action. I think this is the main reason cause the error. Anybody have this experience and have clues for me?
Thanks in advance,
Edit: I'm added video to further explain:
I press emergency stop button
calibrate rest position
the angle all remain the same (as expected)
released the emergency button (J1-J6 angle value start changing, but arm no movement)
press emergency stop button (it stop changing)
release emergency button (J1-J6 angle value changed, arm still no move)
i'd changed the teensy, it seems no longer repeat same problem. Thanks and Issue closed.
Hm.. I'm tried disable encoder seems can't activate arm. Then i notice my Macbook Pro complaint USB connection drain too much power (I use version 2019, with all USB-Type-C).
To avoid Teensy drain too much power from my laptop, I moved the the power source of GX16-2 from Teensy to 5V power supply which is reserve to relay and I then Teensy no more responding for ever 😓. I'm waiting new Teensy reach then can continue my work, hopefully I no further damage the Encoder 😅
Sad, it is bad day for me.
I'm not sure I understand completely but it sounds like it could be a substantial encoder noise or grounding issue. Can you select the open loop (disable encoder) option for each joint on the calibration tab and let me know if the odd behavior goes away.
