This is twice now my J2 has stopped working (No movement up or down) That joint is the only one that gives me trouble. After it stopped working the first time, I took the J2 joint apart, put it back together and it started working again... for about 30 min. The motor driver works and has full power/signal. The J2 motor works (I can hear it whine like it’s trying to turn, but the arm doesnt move in either direction) When I took it apart last time, I ran the J2 motor without the arm and it worked as intended. Has anyone else had difficulty out of this joint as well? If so, how did you fix it?

My robot is working great. Now I’m trying to disable all the motor drivers at the same time if any of the limit switches are made but I’m confused on the wiring on how to do that. Could someone who’s already done this please explain or take a picture of their wiring? Thank you very much!

Looking at the provided wiring diagram (red circle), where am I supposed to actually place the -5V DC wire coming from the motor drivers in order to disable them once a limit switch is engaged? Currently, if I jog the robot in one direction and press the corresponding motors limit switch, the robot doesn't stop; it keeps moving until it comes to the end of the jog movement.

OS: Windows 10, x64 Model: AR2 Hardware: 3D Printed parts (Prusa MK3S; PLA+), AR2 & AR3 hardware kit from anninrobotics.com, stepper motor kit from steppermotorsonline.com Software: AR2 Software 2.0 Problem: When I run the software, nothing happens. Nothing on the arm moves at all. What I've Already Verified: - Wall power (120V AC) - 24V DC Motor driver power supply (120V AC going in, 24V DC coming out) - Motor driver modules are all receiving the full 24V/5V DC (Green LED's on the modules are also lit) - 5V DC Power supply (120V AC going in, 5V DC coming out) - Arduino Mega (5V DC going in and the sketch has been uploaded into it correctly) + Baud rate: 115200 + Com port 10 (Computer recognizes through the Device Manager that the Arduino is connected via USB) - The entire arm is positioned (by hand) completely vertically with no limit switches actively engaged. When I run the AR2 software, I set the com port to 10 and load the "LTEST" program. I then click the green "play" arrow. The program only gets 3 rows in when it comes to an "AXIS LIMIT" fault. Any help would be greatly appreciated.
