Teaching mode and suction

When I try to teach the arm to move and pick something up the suction never comes on when I press the correct button for it. When the gripper is installed that works as expected. The suction cup works when programmed via blocky. Is this a known issue or is there something wrong with my arm?

Another problem I have is when rotating the wrist the suction tube pulls on the wrist causing it to spring back to the wrong position. I can not pick something up and rotate it 180 degrees. From 0 to 180. When I try it springs back to about 150 degrees.

uArm Serial No.: D43639DB0CCF

Firmware Version: 3.1.9

Operation System: NA

uArm Controlling Method: teaching

When I use uArmStudio to record the button does turn on the suction. I did get the on-arm teaching to turn on the suction if I switched to bluetooth.

Hi mspy,

The usage of the button next to power button:

  1. During Offline Learning Mode: switch between suction cup and gripper
  2. While controlling uArm via PC: turn on/off Bluetooth

Sorry for the confusion.

Currently, the logic of the button is weird, since it has two functions in different situation. While could you please give us a video about the servo springing? That would help a lot. Thanks

Thanks for the clarification. That makes sense now. I did not see that documented anywhere.

We should make it more clearly. Thanks for your feedback.
