Hi everyone,
I’ve recently assembled my AR4 robot, and while most things are functioning well, I’m encountering an issue with the J4 joint.
The problem is that J4 can only rotate in the positive direction. When I try to rotate it in the reverse direction, I get an error message saying, "J4 Collision or Motor Error."
I’ve already checked the encoders and switches, and they all work fine. All the other motors are also functioning properly.
Could anyone help me diagnose what might be causing this issue? I’ve attached photos and a video for reference.
Thank you so much in advance!
Error log:
I have noticed the same issue, but have the previous kit (not MK). The lever goes inside the J5 motor mount holes when moving backward. J4 Limit Switch Mount.STL and 10T85 switch fix this, right?
Thank you.
There could be a potential wiring issue. Can you check with a multimeter that the dir input to the driver for J4 has a solid connection from the teensy and that the signal is + in one direction and - in the other?
