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!

What version DM542T drives do you have for the other joints? The newer V4 drivers have a small slide switch for 5v input or 24v input. If you do have the newer driver make sure its set to 5v. Let me know if that could be the issue.
