It worked for me perfectly once. Now, however, when I run it, the wrist starts rotating by small increments every time the arm moves vertically. So right after the arm lowers, the wrist turns to the left, then when it raises up it turns to the left some more. Eventually it winds up all the way at 180 degrees. Even having the wrist reset and using the reset block doesn’t help. I’ve closed the software and restarted it, and it keeps doing this.
It seems to be something other than my code. When I create a “move to” block, the arm goes limp and lets you position it where you want. During this time, if I move the arm up and down, the wrist will start rotating (towards 180 degrees and actually even past the 180 degree mark, further than the normal range of motion) every time.

uArm Controlling Method: Serial port direct GCode commands
Hi, I’m having the same problem with spontaneus wrist movement. It has happened while moving the uArm using G commands through the serial port, but also even when using draw feature in uArmStudio software. This last thing, obviously, ruins completely the drawing being made. It does not happen always, but quite often to be very annoying.
