J4 is the only joint that moves. I am getting COLLISION WARNING on all joints. I did the following troubleshooting: tested that encoders are communicating with ARCS by pressing emergency stop and moving joints: result is that all joints register reasonable changes in values. I verified all wires with multimeter. All stepper drivers are getting signal sent from the Teensy 3.5.

I noticed some warnings when uploading the teensy sketch in arduino: Warning regarding unused variables, syntax warnings, and undefined operations. Is this normal?

The only motor cable that gets power from the driver is J4.

I set the ARCS to open loop and still only J4 moves.

Warnings on ARCS include: AXIS LIMIT, COLLISION OR OUT OF CALIBRATION for all joints. I to reset calibration to rest position, but i still get the warnings.

The green light illuminates on all of the stepper drivers.

Any suggestions on what I should look at next? Thank you!
